ABI Research Expects Adaptive Cruise Control for Most Cars

Adaptive cruise control (ACC) has been an option on high-end luxury vehicles for more than a decade, but in the next few years ABI research says it will become available on mid-size and family vehicles. Costs have been falling slowly but steadily over the years, and now a new development promises to bring significant price reductions for the consumer.

“The highest cost component of ACC has always been the radar sensor,” says ABI Research principal analyst David Alexander, “and now the cost advantages of silicon technology are going to take effect. We project that, by 2016, the lower costs will play a big part in increasing volumes and push the global market value up to $30 billion.”

While cameras and lidar sensors are still contributing to ACC systems, especially for the low-speed and stop-and-go features, the core component is still the radar sensor. With Freescale Semiconductor announcing in November 2010 that its Xtrinsic chipset is going into production, the new silicon-germanium technology will allow automotive radar sensors to benefit from the efficiency of the latest CMOS manufacturing techniques. Other suppliers are likely to follow.
“We also expect intelligent speed assistance (ISA) systems to begin appearing in 2013,” says research director Larry Fisher. “However, rather than being pushed as the next big thing, ISA will take the form of an add-on feature to increase the value of existing packages that include navigation systems and forward-looking camera sensors.”

ABI Research still doesn’t see any proposed financial incentives to encourage the public to invest in speed control systems, but the latest NCAP (New Car Assessment Program) assessments are now including driver assistance systems, and manufacturers will have to start offering them to maintain high star ratings. Research has shown that both ACC and ISA can have beneficial effects on traffic flow when used in sufficient numbers.

A few years ago at M/A-COM (now part of Autoliv), the automotive group was making good in-roads into SiGe designs which has been used in their latest generation ACC modules. This really drove the cost down along with lower cost packaging/antenna materials so I can see this being more widely available on mid-range vehicles as an option.

Pat's Predictions for 2011

Last year was my first year of predictions for the RF and microwave industry. So what are my predictions for 2011 and how did I do last year?

2011 Industry predictions:

1. Tunable devices and circuits like RF MEMS and switched capacitor banks will be adopted in cell phones and alleviate some of the antenna reception issues that plagued phones like the iPhone 4.
2. Smart Grid applications will take off this year with ISM and Zigbee wireless applications being widely implemented around the world.
3. LTE will dominate the 4G networks as it is implemented around the world and zooms past WiMAX in deployments.
4. Femtocells, WiFi and other shorter range wireless technologies will be implemented to get around cellular dead spots instead of just deploying more basestations to fill in coverage.
5. Metamaterials will start to be used in real world devices for filters and other passive devices (maybe even radar cloaking for the military).
6. Adaptive/Cognitive radar and commnication systems will go into real development programs.
7. Millimeterwave frequency solutions will dominate the new backhaul and satellite communications deployments.
8. SOI and SOS based switches will start taking market share from the traditional dominant GaAs markets.
9. The confusion of the definition of 4G technologies will continue while someone will define and start using the term 5G.
10. Microwave applications will see significant use in medical technologies to enhance cures for diseases such as cancer.

And here are my 2010 Predictions and Outcomes:

1. The US Gov’t Broadband Initiative Stimulus money will be slow to come but even with the many hundreds of millions given out, it will have little or no affect on rural broadband access penetration (see our Oct 09 article on the Broadband Stimulus Program) - I would say this was right as millions were poured into the Broadband Initiative but it seemed to have little effect on market penetration.
2. LDMOS and GaN will gain major market share in the power product applications and become the leading materials for high power applications in their respective frequency sweet spots (see our June 09 article on the Power Brokers) - I think this was pretty close as LDMOS has dominated the basestation and lower frequency high power products in several areas and GaN has taken a significant hold in many new military and other high power markets.
3. We will see some control components integrated on GaN MMICs (i.e. switches, limiters, etc.) - I am doing well as at least 2 suppliers (Cree and TriQuint) released GaN switch products (See the end of the Nov cover story on Switches) so this one is also correct.
4. Nonlinear characterization advancements in the last couple of years will take hold in the marketplace as widely accepted techniques (X-parameters, S-functions, etc.) - Well, I don't think this was totally correct as these new techniques did become more widely known, but I not sure how widely used that are but this year should complete the task. We plan on trying to have a panel session on this subject at IMS 2011.
5. Several amplifiers with greater than 80% efficiency above 1 GHz will be developed as new high efficiency design techniques are exploited - This goes along with the previous prediction and while there are several examples of power amps over 60 and 70% efficiency, I could not find any over 80%. Have you seen any?
6. LTE will make large gains in deployments but not come close to exceeding WiMAX in the number of users (in 2011 I predict LTE will overtake WiMAX) - LTE was all the rage in 2010 and will continue to be in 2011 but I was correct that there were far more WiMAX deployments than LTE by the end of 2010. In an ABI report in Dec 2010, it was stated that at the end of 2010, mobile WiMAX will cover about 8% of the world’s population, while LTE will cover about 2%
7. SoC and SiP solutions will start to take hold in several applications where discrete solutions used to rule (WiFi, GPS, Bluetooth, etc.) - see our Feb 09 article on SoC/SiP - There are several companies supplying single chip solutions for WiFi, Bluetooth and ZigBee so I think this one is mostly correct (TI, RFMD, BroadCom, SiGe, etc.)
8. Wireless HDTV products will be released into the mass market and one protocol will distance its self as the leading solution of the 4 vying for acceptance (see our Aug 09 article on Wireless HDTV) - This market did not really mature yet (maybe this year) so I think I got this one wrong.
9. RFID will finally take off and see significant growth in multiple markets including front of the store (POS) applications - Same thing as above prediction so this one was wrong also.
10. As a result of the terrorists taping into our UAV video signals, new funding and significant resources will be spent on wireless encryption for the US military - This was somewhat true as there was emphasis to improve wireless security but I don't recall any major programs to do it so maybe I was only half correct here.
11. As a result of the failed terrorist attack on the Detroit bound plane, there will be renewed interest and purchases of mmWave and Terahertz body scanners for airport security - This was a hot topic as several groups and many individuals made a big fuss about going through the mmWave and X-ray scanning machines as they were widely deployed so I got this one correct!
12. As the military backs off the Future Combat Systems approach as being too expensive, advanced software defined radios will be demonstrated for near future systems - This was somewhat correct but again, I don't recall any major programs in this area so maybe it is only partially correct.
13. Smart IED jammers will be developed that actively adapt to different frequencies via software control as IED attacks continue to dominate our attention (see our August 08 supplement article on IED Jammers) - I think this one was correct and a new program was just announced that BAE Systems will develop electronic warfare machine learning to jam enemy adaptive communications automatically
14. A new military broadband satellite communications program will be proposed to ease the capacity crunch for bandwidth (see our August 09 article on the SATCOM Capacity Crunch) - I think this one was wrong as I did not hear about any such programs.

So if you count half points, I got 8 out of 14 correct!

The end of the year in pictures

With my camera-enabled Blackberry (or any phone), its much easier to record life's little snipets for posterity. Eventually though, its time to get those images off the phone's memory, to start a new collection of moments for sharing. And so this week I find myself cleaning out my camera's memory at years end.

I'm not one to take pictures frequently (with a camera or phone), but I did travel quite a bit for work towards the end of 2010 and that is when I am most likely to "snap a few shots". And so here's a quick photo essay of the end of 2010, from the perspective of a roving Microwave Journal editor. Got some industry related shots of your own? Send them to me at dvye@mwjournal.com and we'll consider posting them in a master photo album for the holidays. Enjoy !

Back in November, I travelled with our Northeast Regional Sales Manager, Mike Hallman to the Garden State, where we met a number of hard working RF/mW vendors. New Jersey has a great community of Microwave shops including Voltronics, Synergy, Wireless Telecom Group, MECA, Anatech, Pulsar, GT Microwave, Astrolab, and Anadigics just to name a few. I used to travel there frequently back in my Ansoft days (former Compact Software facility) and have a fondness for the state.















George Apsley, Chief Engineer Product Development and Amy Kulp, Marketing Director, GT Microwave with Mike Hallman, Regional Sales Manager, Microwave Journal.

It was at GT Microwave that I took these pictures. Its not every company whose founder is married to a stained glass artist. If that was the case, perhaps more lobbies would be adorned like GT Microwave. An RF power combiner in stained glass is certainly a thing of beauty. The detail in the coax connectors is amazing, right down to the flange screws. If you're in Randolph New Jersey, pay GT Microwave a visit.





APMC/MWE 2010

Here's MWJ publisher Carl Sheffres and Horizon House Event Manager Michel Zoghob together at our booth at APMC/MWE 2010 in Yokohama, Japan. They've been working so closely for years that they are starting to look related. Dont you agree? This was in early December. Great time for a long flight, a glimpse of the Japanese microwave market and some Sushi.

I loved this display. A famous radio tower in Japan constructed from semi-rigid coax cables and a variety of connectors (BNC, SMA, N-type, etc.). I was informed that last year they used similar components to reconstruct a famous Tokyo bridge. Perhaps next year they will go for a Godzilla design. Either way, very creative use of coax and connectors and a good way to get a show attendee to stop by the booth and hear some more about the company. OK MTT exhibitors, here's an opportunity to raise the bar on creativity.






I call this the Microwave Menora but actually it is a very interesting, millimeter-wave waveguide combiner for 60 GHz. Again this is from APMC/MWE. Japan has long been interested in 60 GHz applications, often tied to collision avoidance radar for automobiles. This is a fine example of the precise engineering and machining on display at APMC.


EuMW 2010

Final image for the year goes back to the roving editor in Paris at European Microwave Week this past September. Here I am after the first day at the show in the Latin Quarter, worried that I have arrived too late for the early bird, frog leg special. Our first European Defense/Security Executive Forum went off smoothly. The success of this event and the superb food (no frog legs but plenty of Fois Gras) made for a memorable trip.

GaAs Market Recovers Strongly in Recent Report

According to a report from Strategy Analytics last weeek, the market value for GaAs revenues, driven by smartphones and consumer adoption of data-intensive applications, has grown strongly from the lows it struggled for in early 2009. The recently published Strategy Analytics GaAs and Compound Semiconductors (GaAs) report, “GaAs Device Vendor Market Share 2009: North America,” reports that this growth brought the total market value for GaAs revenues to little more than $4 billion, a slight increase over 2008 revenue levels.

Skyworks Solutions nudged past RFMD to take the top revenue spot for North American vendors. However, less than one percent market share separates both companies. TriQuint and Avago Technologies both recorded strong revenue growth, substantially gaining on industry leaders. “Even though revenue from the GaAs market in 2009 was only slightly higher than 2008, the story that emerges is the strong industry recovery during the last three-quarters of the year,” noted Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Service. “This growth is driven by consumer demand for new data-intensive applications, smartphones and the infrastructure that supports these capabilities. We expect these drivers to continue fueling growth through 2010.”

The report provides strategic comments, representative products and selected news items for a comprehensive set of North American GaAs vendors. It also identifies the top ten global vendors in terms of GaAs device market share. Strategy Analytics estimates that six of the top ten GaAs vendors—including all four top contenders--are located in North America.

RFMD and Skyworks are always a close 1 and 2 with TriQuint right behind them but I have seen Avago making big push to break into the top 3.

ABI Projects RF PA Revenue for Mobile/Cellular Markets

ABI recently talked about the rapid Chinese TD-SCDMA rollouts and the often-maligned GSM/GPRS/EDGE equipment markets have benefited the base station RF power amplifier and RF power device markets. The stated that GSM/GPRS/EDGE RFPAs and devices are still shipping in the millions. The Asia-Pacific region is presently accounting for more than 50% of the RF power semiconductor devices sold into the mobile wireless infrastructure segment.

Recent Chinese TD-SCDMA base station deployments have been massive, and have buoyed RF power vendors to a tremendous degree. That demand is expected to strengthen the market until at least sometime in 2011, and the Chinese deployments will probably only start to slow in 2012. And in a happy coincidence for equipment vendors, 2011 is the expected time frame for LTE deployments in developed countries to really gather a head of steam. Below is a nice graph of how they project the mobile/cellular PA market to breakdown over the next 5 years:

Microwave Backhaul Favored in W. Europe and Most of Asia-Pac

A new ABI report says that capital expenditure on mobile backhaul varies greatly by region and by technology. While most countries face similar current or future struggles to reduce network congestion, the solutions being adopted differ according to existing infrastructure, network generations, and government mandates and incentives.

One major division is whether to use optic fiber or microwave for mobile backhaul. CAPEX for microwave backhaul will peak in Western Europe this year at almost $4.4 billion, more than triple the figure for the next-highest region, Asia-Pacific. The European spending surge is due to the expansion of 3G networks to new areas, as well as a few initial 4G network deployments.
“Once that wave is completed in Western Europe, microwave backhaul will be left alone for a while,” comments ABI Research analyst Xavier Ortiz. “Following the 2010 spending spree, Western European microwave backhaul CAPEX will tumble in 2011 to just over half its peak level.”

Virtually all world regions will see some increase in microwave backhaul CAPEX over 2011-2013, followed by a gradual decline. The reasons vary by location. In Asia, many 3G networks will be rolled out during that period, and others will be expanded to reach remote, underserved areas. According to practice director Aditya Kaul, “Asia’s investment in microwave backhaul would be even greater were it not for the Chinese government’s mandate to use fiber for the country’s 3G and 4G networks. Although microwave is less expensive and faster to deploy, a governmental commitment to fiber means huge economies of scale, and fewer worries about zoning permissions.”

In the United States, the situation is very different. The prevalence of fiber optic cable in many parts of the country combined with the high cost of tower leasing mean that interest in microwave as a backhaul solution is lower than anywhere else. “Large service providers are saying they will only use microwave where fiber is unavailable,” says Ortiz.

It is interesting how Fiber and MW backhaul use differ from region to region. The economics and policies are very different in each region. I would think it would be mostly based on cost but that is not the case. Do you think China will ever change their mandate for Fiber only?

Microwaves and the Universe

In cosmology, cosmic microwave background (CMB) radiation (also CMBR, CBR, MBR, and relic radiation) is a form of electromagnetic radiation that fills the universe. Unlike a traditional optical telescope, whereby the space between stars and galaxies appears pitch black, the radio telescope, exhibits a faint background glow between celestial bodies, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object. This glow is strongest in the microwave region of the radio spectrum, hence the name cosmic microwave background radiation.

Most scientists believe the universe was created in the Big Bang around 13.7 billion years ago. Stars and galaxies started to form around 300 million years later. Our Sun was born around five billion years ago, while life first appeared on the Earth around 3.7 billion years ago. The CMB dates back to 300,000 years after the Big Bang and has now cooled to around -270 degrees C. Precise measurements of cosmic background radiation are critical to cosmology, since any proposed model of the universe must explain this radiation. The CMBR has a thermal black body spectrum at a temperature of 2.725 K, thus the spectrum peaks in the microwave range frequency of 160.2 GHz, corresponding to a 1.9 mm wavelength. This holds if you measure the intensity per unit frequency, as in Planck's law. If instead you measure it per unit wavelength, using Wien's law, the peak will be at 1.06 mm corresponding to a frequency of 283 GHz.

Nasa’s Wilkinson Microwave Anisotophy Probe (WMAP) is a NASA Explorer mission that launched June 2001 to make fundamental measurements of cosmology -- the study of the properties of our universe as a whole. WMAP is responsible for mapping CMBR and has been stunningly successful, producing our new Standard Model of Cosmology including the first fine-resolution (0.2 degree) full-sky map of the microwave sky.


Concentric circles discovered in cosmic microwave background radiation (CMB) – the after-effects of the Big Bang – display evidence of events that took place before most scientists believe the universe came into being. The recent controversial finding points to the existence of a universe that did not begin 13.7billion years ago, as is generally accepted, but is instead a cycle of so-called aeons. The discovery has been posted online on the website arXiv.org by respected scientist Professor Roger Penrose from Oxford University and Professor Vahe Gurzadyan from Yerevan State University, Armenia.

But Penrose and Gurzadyan argue that evidence unearthed by WMAP shows imprints in the radiation that are older than the Big Bang.. They say they have discovered 12 examples of concentric circles, some of which have five rings, meaning the same object has had five massive events in its history. The rings appear around galaxy clusters in which the variation in the background radiation appears to be strangely low.


The research appears to cast aside the widely-held 'inflationary' theory of the origins of the universe, which claims the universe began with the Big Bang, and will continue to expand until a point in the future, when it will end.
They believe the circles are imprints of extremely violent gravitational radiation waves generated by supermassive black hole collisions in a previous aeon before the last big bang.

They say that this means that this means that the universe cycles through aeons dominated by big bangs and supermassive black hole collisions. Penrose believes that his new theory of ‘conformal cyclic cosmology' means that black holes will eventually consume all the matter in the universe. According to this theory, when the black holes have finished consuming all the matter in the universe, energy will be all that remains, which will then trigger the next Big Bang - and the new aeon.

Penrose told the BBC: 'In the scheme that I'm proposing, you have an exponential expansion but it's not in our aeon - I use the term to describe [the period] from our Big Bang until the remote future. 'I claim that this aeon is one of a succession of such things, where the remote future of the previous aeons somehow becomes the Big Bang of our aeon.'

More Fun with MM-Wave Body Imaging

Thanks to the “don’t touch my junk” traveler, most of the public is now aware of the controversy over the body imaging technology being employed at various airports (65 as of October 2010). Two types of body imaging technologies are actually employed. The first one known as Backscatter X-ray is an advanced imaging technology that detects the radiation that reflected from the target. . Traditional X-ray machines detect hard and soft materials by the variation in transmission through the target. A competing technology is millimeter wave scanner which produces a 3D image whereas the backscatter x-ray 2D image. The airport security machines are also referred to as "body scanner", "whole body imager (WBI)", and "security scanner".

Its oddly humorous to see microwave technology back in the mainstream news (I considered the Apple iPhone antenna design flop to be a microwave story). In August of 2006 - Endwave announced an agreement to manufacture a complete RF system for a portal scanner used in a variety of security applications. The company would fully integrate and test the active RF subsystems which form the vertical electronic scanning array (or RF mast). Once assembled into the mechanical housing, each RF mast rotates 180 degrees around a person standing in the portal, providing a full 360 degree scan of the body within a matter of seconds. These masts would incorporate a full suite of Endwave switch arrays and transceivers, along with the associated cabling and surrounding framework that holds the scanning antennas onto each side of the portal.

In August of 2008, the Microwave Journal discussed this technology with an Endwave executive in our Executive Interview series:

MWJ: One interesting millimeter-wave application is “whole body imaging” that is being developed by L3 Communications for security and detection systems useed in places such as airports and government facilities. What’s Endwave’s contribution to this system and will they eventually replace metal detectors?

MH: I think our relationship with SafeView (part of L-3 since they were acquired in 2006) is one that deserves some special attention. We initially began our relationship with this private Santa Clara start-up by designing the Tx/Rx modules that went into their first generation scanner. This was straightforward for us, given our leadership in telecom transceivers and the similar technology and manufacturing processes used in our core business. Soon after, we were awarded the switch modules that allow the transmit signal to quickly switch between antenna elements and scan the body from floor to ceiling. Still later, SafeView awarded us the entire RF “mast” – or chassis, of which there are two inside any ProVision™ portal. These 7-foot tall chassis include all of our electronics, plus all the associated cabling, connectors, and metalwork. We integrate all that, run final test, and deliver these large masts to L-3 SafeView where they do the final integration into the portal and ship it out the door. So you can see we are far more than your everyday module supplier.

In April of this year, the Transportation Security Administration Chief, Kip Hawley, publicly announced that the TSA was going to ramp up purchases of millimeter-wave checkpoint security equipment. Specifically, the L-3 SafeView ProVision™ portals were singled out for deployment in many US airports. During Q2 of this year, the TSA began deploying 38 ProVision™ scanners in LA, Baltimore, Denver, Albuquerque, Dallas, Detroit, Las Vegan, Miami, and New York’s JFK airport. Even more encouraging were comments from other TSA officials stating that the scanners could eventually replace metal detectors at the nation's 2,000 airport checkpoints and the pat-downs done on passengers who need extra screening. In addition to these airport checkpoint deployments, L-3 has publicly stated that scanners are already used in many different locations, including a few courthouses, jails and US embassies, as well as overseas border crossings, military checkpoints, government buildings and some foreign airports such as Amsterdam's Schiphol. So, it will be difficult for anyone reading this article to NOT see these millimeter-wave portals if they do airline travel. That should be exciting to our entire industry, as it’s sort of like “millimeter-waves going mainstream”.

MWJ: That is very interesting and I look forward to seeing this technology showing up in airports, especially if it means getting through security faster.

So despite the benefits, the public and TSA official need to resolve the objections people have to machines that can look through clothes.

Cell Phone Radiation Risks - Now I have seen it all

There has been a wide array of cell phone radiation protection devices such as antenna shields, cell phone holders/covers, gloves and hats but now there is Belly Armor. It claims to protect an unborn child from everyday radiation from sources ranging from cell phones to WiFi with a material that is provided to act as a Faraday cage. It comes in various forms such as a blanket, belly band and tee.

I have not seen any evidence that non-ionizing radiation does any damage to the body other than heating from very high power sources. The FCC has set conservative limits on the power levels of cell phones and other devices in order to protect the public but there are still many concerns about long term exposure to various sources of radiation.

Can anyone point to any conclusive reports or studies that I have missed? What do you think??

The 4G Controversy

Some industry experts and research analysts agree that today's WiMAX (802.16e) and LTE technologies are 4G but do they really meet the definition of 4G as others say they do not. Now that the ITU has officially accepted 802.16m and LTE-Advanced as IMT-Advanced technologies (4G), the issue has surfaced again. What makes it more confusing is that where the ITU mainly referred to IMT-2000 and IMT-Advanced in the past, it is now including 3G with IMT-2000 and 4G with IMT-Advanced.

It is true that the current LTE and WiMAX systems are 4th generation networks so shouldn't they be called that. But 4G networks should also meet some minimal performance specs for data rates, security, etc. (ITU now specifies 4G with peak rates up to about 100 Mbit/s). With the ITU's specifications of 4G now published, the performance specifications for 4G are far above those of current systems making them more like 3.9G (or something like that) as their speeds are in the tens of Mbit/s speeds.

All the carriers are calling their latest networks 4G any way in order to keep up with their marketing to the public of the latest faster networks. T-Mobile is saying their new HSPA+ network is 4G; AT&T and Verizon are deploying LTE networks as 4G; and Sprint and Clearwire are deploying WiMAX in the same way. So the point is probably mute as these carriers are already defining and marketing their current networks as 4G, so I think it is too late for the ITU to define it. But I agree that the ITU has a more proper definition since performance specifications are spelled out to quantify the requirements.

Here is our latest article written by the UMTS Chairman about the evolution of from HSPA to LTE and beyond. What do you think?

and the winner is....

NFC Rumored to be in Next iPhone

There was a report last week that Apple is already testing a prototype iPhone with near-field communication (NFC) capability inside that could lead to using future iPhones as a mobile wallet or payment device. Unnamed sources say that Apple is testing an iPhone with NFC chips procured from NXP Semiconductor. It's not clear what exactly what they are testing and is very preliminary at this point. But coupled with the hire of Benjamin Vigier from mFoundry as mobile payments product manager, it seems possible that Apple could be planning to open up to mobile commerce.

Using it the iPhone for payment seems to be a good idea for Apple, which has 150 million credit cards already hooked up to iTunes accounts, as CEO Steve Jobs announced in June to its annual meeting of developers. There are applications being built for iOS devices as well as Android and other platforms that enable mobile payment, so building in a contactless payments feature makes sense and has been tested and used in other countries like Japan.

Do you think the iPhone will be the first to implement NFC or will an Android phone beat them to the punch?

MILCOM 2010 - Utilizing Smartphones for the Warfighter

One of the major trends at MILCOM this year is leveraging the use of commercial smartphones for military use to field advanced communications to the field quickly. Billions of dollars are invested in commercial development for smartphones so why not use that advanced technology for the military. The commercial market also updates capabilities quickly so if the commercial smart phone can "plug" into a secure military network, the comm device does not become obsolete after a year or two.

One of the best examples of utilizing this strategy is Lockheed Martin's MONAX 3G broadband network. MONAX is designed to bring an affordable, 3G broadband network to Warfighters at the first tactical mile and enables the use of smartphones and delivers smartphone data, imagery, video and applications. Lockheed has designed a "brick" device (called a Lynx) that has a battery, antenna and RF circuitry to transmit and receive secure 3G communications to the network that the smartphone just clips into. A rubber sleeve is also used to encase the smartphone to make it more rugged. The device uses standard AES 256 encryption and utilizes different frequencies than commercial networks so as to not interfere with the local communications. The basestations can be put up on towers but are better used on airborne platforms like balloons where they are quickly deployed over the area and provide wider coverage. Below is a short video demonstration of the MONAX network.

The MONAX devices are available on GSA for around $1000. They provide a low cost quickly deployable network that can be used now. It is well suited for the Warfighter, disaster communications, rescue situations and similar situations where secure communications are needed quickly. It is not a fit for top secret or highly rugged communications but is a possible solution for most military communications needs. It is currently a 3G network but can be updated as the technology progresses to 4G and beyond.

They plan to build a library of apps appropriate for the Wargfighter such as mapping programs, video surveillance, facial recognition for identification, battle planning, medical apps to forward injured soldier information ahead to the medical unit and more. This will provide capable communications now while other programs come on line in the future like JTRS and WIN-T. The might be a secure iTunes app store in the future!

FAQs - 4G and Future Directions in Cellular Wireless Standards

Q: What is 4G and where does it fit in the development of cellular communication standards?

A: 4G refers to the Fourth Generation of cellular wireless standards.

The First Generation (1G) of cellular wireless supported analog mobile phones. This transitioned to Second Generation (2G) digital service, which offered a significant upgrade in capabilities. The Third Generation (3G) supports multi-media, spread-spectrum transmission with larger volumes of data transfer and improved speeds. It enables numerous applications including e-mail and web browsing.

Fourth Generation (4G) takes the capabilities of wireless a step further. 4G increases bandwidth and modulation complexity and adds spatially multiplexed data streams (MIMO). This in turn increases the data rates and enables exciting new services and applications. For example, the key 2G application was voice. 3G brought data services to the market, enabling e-mail and web browsing. 4G applications are still being defined but may include things like streaming video.

Q: Where are we with 3G and the shift to new standards for 4G networks?

A: Major US wireless networks are using 3G specifications, providing users with a noticeable improvement in data speed. 3G allows simultaneous use of voice and data transfers. The speed of a smartphone browser, and the ability to send and receive pictures and larger files, are significant 3G enhancements.

While 4G offers even more capability, there are different approaches to 4G standards. Whenever there are new generations of wireless standards, differing innovations are developed and tend to find their own audiences over time.

The major 4G standards are Long Term Evolution (LTE) and WiMAX (also known as 802.16m). LTE commitments are the logical extension for organizations whose current systems are UMTS / 3GPP based. LTE is favored by organizations that hold paired frequency spectrum allocations. WiMAX commitments tend to come from organizations that hold unpaired frequency spectrum allocations, although there is significant interest in the time division duplex version of LTE (TD-LTE) here as well.

Regardless of which standard eventually prevails, TriQuint will support new generations of systems to assist all developers as they work towards continuous improvement.

We do this while looking ahead of the current trends in the evolution of wireless.

Q: What exactly are the improvements that make each new Generation?

A: Generation changes in wireless communications generally have to do with both the data rate and architecture of the system infrastructure. It is safe to say that each new generation enables higher data rates, lower latency and new applications relative to the previous one.

One major change is that 4G systems use a packet infrastructure rather than traditional telephone architecture. Since 4G is relatively new, it will still take time for the full extension of the improvements to present themselves.

Q: With the acceptance of 3G and 4G, is the 2G system obsolete?

A: While 2G systems have been surpassed by new generations of wireless, the system remains viable and has a large user base in areas where 3G and 4G systems have not been deployed. It will continue to be important for several years into the future. At some point, it is likely that the 2G spectrum will be refarmed to support newer generations of wireless services.


Q: What are WiMAX, WiFi and LTE technologies? How do they fit into the 4G network?

A: LTE is a cellular communications protocol for 4G networks. LTE is favored by organizations that hold paired frequency spectrum allocations and especially those whose current systems are UMTS / 3GPP based. There is also growing interest in the time domain version of LTE – TD-LTE – for use in unpaired spectrum.

WiMAX is also a communications protocol for 4G networks It is also known as 802.16m and tends to be favored by organizations that hold unpaired frequency allocations.

WiFi is a short-range communications protocol popular for consumer devices and also a familiar term with broad audience recognition. WiFi is best viewed as a supporting protocol that works in conjunction with LTE or WiMAX devices rather than as a competitive technology.

Comparisons and confusion between LTE, WiMAX and WiFi are frequent because all are related to the ability to wirelessly connect and provide Internet access. WiFi generally operates in a home or office building to connect computers, smartphones and other wireless devices.

Q: What are the major design considerations for 4G systems?

A: The most significant changes are new frequency bands that have been opened to support the 4G services. The most well known examples are in the “Digital Dividend” bands where former analog TV channels have been refarmed for 4G services. Other changes are wider bandwidths, more complex modulation and the usage of spatial diversity (MIMO) to improve data rates.

Q: What can we expect in future 5G or 6G systems?

A: The main goals for new generations of wireless service will surely include the ability to handle massive amounts of information without any delay.

Communications will be clearer as they become increasingly error free and reliable no matter where you are. New generations of wireless will have the ability to sort through, identify, send and receive wireless transmissions on ever more crowded airways.

Safety and security, always a concern, will be built deeper into the systems to protect information, provide privacy and integrate all aspects of wireless. Astonishing new applications are always on the horizon. These will need new generations of wireless capabilities that TriQuint research is dedicated to help design and build.

MILCOM 2010 - First Impressions

Although IP communications have been around for many years, interoperable and secure IP systems are now being realized in many military applications. The Warfigther is now being connected with vehicles, UAVs, ships, helicopters and other aircraft so that everyone can share information immediately and there is no single point of failure in the network as they can all act as nodes. This year's theme, "The Next Decade of Military Communications," addresses the issues with connecting various Defense, intelligence and homeland security networks as well as the evolution of communications systems and networks as we move into network-centric operations as the president and CEO, Wanda Austin, of the Aerospace Corporation put it in her welcome letter to attendees.

Although the major players are all here such as Boeing, GD, Raytheon, Harris, NGC, etc. Lockheed Martin seems the most active as they and the Aerospace Corporation were the co-sponsors for the show. They are showing off AMR-JTRS and MONAX 3G broadband network. AMR-JTRS provides a secure mobile network allowing rapid connectivity. JTRS provides communications between Warfighters and AMF provides new IP-enabled waveforms that deliver high data throughput and secure internet capability (to 10 Mbps). As JTRS units are deployed to aircraft, vehicles and Warfighters, they can now form ad hoc networks and seamlessly communicate voice and data. MONAX is designed to bring an affordable, 3G broadband network to Warfighters at the first tactical mile and enables the use of Smartphones and delivers Smartphone data, imagery, video and applications.

Most of the component and test/measurement companies are also here so I will make the rounds today and interview as many of them as I can. I will have a show summary up by the end of the week.

Handset Market is Robust - Some Component Shortages Seen

Good news for cell phone component manufacturers as ABI Reserach reports that the mobile handset market is set for a stellar performance in 2010. 3Q-2010 is up 346.2 million in handset shipments. For the first three quarters of the year, YoY growth has been hovering around 20%. “This is a remarkable feat, irrespective of the rebound effect following the deferred handset purchases during the economic recession,” says Jake Saunders, VP for forecasting at ABI Research. “Layer on ‘smartphone-envy’ and you have a recipe for high handset volumes.”

This rebound is having some interesting consequences:
1) Component manufacturers have never had it so good. Nokia in particular reported a hardware crunch, especially with displays (e.g. AMOLED) and semiconductor components for low-cost handsets. Nokia’s leading market-share in this segment has increased Nokia’s exposure to the component crunch.

2) Vendors that have strong portfolios in smartphones (RIM, Apple, HTC and Motorola) have seen their growth in market-share outperform the market. This effect is likely to continue into 4Q-2010 and 2011.

3) Unless Nokia can resolve its component resourcing challenges, it is likely to be supply-constrained again in 4Q-2010, a quarter that typically equates to 30% of annual handset sales. “Nokia’s market-share could well come under further pressure,” adds Kevin Burden, VP and practice director for mobile devices.

4) Handset vendors with greater in-house ability to source their own components (e.g. Samsung and LG) will be able to take advantage of the market opportunity to expand volumes.

5) Typically a handset boom period is followed by a market softening as customers wait for the next “must have” handset feature innovation to make its way to the market. We should not be unduly worried. There is still considerable room for innovation in the smartphone sector, not just “feature innovation” but also “cost reduction innovation,” which should keep customers keen.

The spotlight has to be put on Apple and RIM: they increased their market-shares to 4.1% and 4% respectively. While Samsung did manage to demonstrate quarterly growth (to 20.6%), other vendors contracted: Nokia (31.9%), LG (8.2%), Sony-Ericsson (3%), Motorola (2.6%).

From a volume point of view, ABI reported that total shipments of mobile handsets are expected to be 1.34 billion by YE-2010 and should maintain their momentum all the way to 2015, which will see more than 1.7 billion in handset shipments.

“The Asia-Pacific region currently makes the largest contribution to global handset sales,” says ABI Research industry analyst Celia Bo. “Handset sales are projected to increase 9% this year compared to 2009, and will account for 38% of total shipments. China is clearly a major source of handset demand, but it is not the only one. India and Indonesia are also expanding their domestic demand.”

The Indian handset market is expected to grow from 84.3 million handsets in 2009 to 104 million in 2010, a Year-over-Year growth of 24%. Similarly, Indonesia is not insignificant. Many of its 240 million people confidently purchased 33 million handsets in 2009 and that figure is expected to surpass 37 million by the end of 2010. Both markets have traditionally been fertile ground for Nokia distributors and dealers. In those markets, the Finnish manufacturer has enjoyed a market-share well above its global average.

Nokia has been very effective in producing ultra-low cost handsets that are robust and user-friendly and at the right price-point. However, Nokia has seen its market-share steadily eroded in the mid- to high tiers as India’s and Indonesia’s aspiring middle classes purchase high-end feature phones and smartphones. Vendors such as Samsung, LG and RIM have been net beneficiaries.

“A number of local handset vendors such as Micromax and Spice Mobile in India, and Nexian and SPC Mobile in Indonesia, are intent on catering to low-end and mid-tier end-users,” notes VP and practice director Kevin Burden. “Their game-plan is to push the envelope on providing increasingly feature-rich handsets at aggressive price-points.”

‘Wireless’ humans could form backbone of new mobile networks

Members of the public could form the backbone of powerful new mobile internet networks by carrying wearable sensors.

According to researchers from Queen’s University Belfast, the novel sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.

The engineers from Queen’s renowned Institute of Electronics, Communications and Information Technology (ECIT), are working on a new project based on the rapidly developing science of body centric communications.

Social benefits from the work could include vast improvements in mobile gaming and remote healthcare, along with new precision monitoring of athletes and real-time tactical training in team sports.

The researchers at ECIT are investigating how small sensors carried by members of the public, in items such as next generation smartphones, could communicate with each other to create potentially vast body-to-body networks (BBNs).

The new sensors would interact to transmit data, providing ‘anytime, anywhere’ mobile network connectivity.

Dr Simon Cotton (Dr. Cotton wrote the lead story for the MWJ 2010 August Supplement) , from ECIT’s wireless communications research group said: “In the past few years a significant amount of research has been undertaken into antennas and systems designed to share information across the surface of the human body. Until now, however, little work has been done to address the next major challenge which is one of the last frontiers in wireless communication – how that information can be transferred efficiently to an off-body location.

“The availability of body-to-body networks could bring great social benefits, including significant healthcare improvements through the use of bodyworn sensors for the widespread, routine monitoring and treatment of illness away from medical centres. This could greatly reduce the current strain on health budgets and help make the Government’s vision of healthcare at home for the elderly a reality.

“If the idea takes off, BBNs could also lead to a reduction in the number of base stations needed to service mobile phone users, particularly in areas of high population density. This could help to alleviate public perceptions of adverse health associated with current networks and be more environmentally friendly due to the much lower power levels required for operation.”

Dr Cotton has been awarded a prestigious joint five-year Research Fellowship by the Royal Academy of Engineering and the Engineering and Physical Research Council (EPSRC) to examine how the new technology can be harnessed to become part of everyday life.

He added: “Our work at Queen’s involves collaborating with national and international academic, industrial and institutional experts to develop a range of models for wireless channels required for body centric communications. These will provide a basis for the development of the antennas, wireless devices and networking standards required to make BBNs a reality.

“Success in this field will not only bring major social benefits it could also bring significant commercial rewards for those involved. Even though the market for wearable wireless sensors is still in its infancy, it is expected to grow to more than 400 million devices annually by 2014.”

Wireless Charging of Cell Phones Coming to Cars

Car makers are showing their interest in wireless charging as a General Motors executive is chairing a standards effort that hopes to set interoperability standards for the magnetic induction approach. Toyota and Ford said they also are interested in the technology and the standards effort.

The Consumer Electronics Association is trying to set a baseline for interoperability for chargers using magnetic coupling. One spec will target connections of less than 1 cm from coil to coil while another will address a 2-6 cm distance. The group will also try to define power efficiency and standard nomenclature for different technical approaches. The committee has said they will look at all the technologies that could provide wireless charging such as optical, RF and conductive as well as inductive approaches.

Smartphone apps for car functions and controls are a high priority for car makers now as the activity in this area has taken off quickly. Wireless charging is another point of integration and convenience to smartphone users. Although Toyota did not seem to think it is a high priority at this point, most car makers are working in this direction.

A Tablet Could be Your Next Restaurant Menu

Tablets are quickly being adopted for many applications in business. I see real estate agents and contractors carrying them around to show clients information or take notes about a project. Now a new startup, E La Carte, is developing a new tablet-like computer for use in restaurants as a digital menu and ordering device. E La Carte is just one company trying to apply technology to help restaurants operate more efficiently and profitably while making customers happier. The company’s system is currently being tested at various Uno Chicago Grill locations.

E La Carte’s technology could help solve some restaurant frustrations and might get customers to spend a more. Customers can review the menu using a touchscreen tablet device and place their order when they are ready as the device is connected to the restaurant’s existing cash register system via Wi-Fi. There are also games and trivia to entertain you while waiting plus it offers functions such restaurant feedback, splitting the bill among several people, figuring out the tip, and paying via credit card. Being able to order and pay the bill when you are ready rather than waiting for the waiter/waitress to come by seems like a big advantage to the system and maybe you will order an extra beer since you can just press a button. Games and other entertainment applications can also keep kids occupied while waiting for the food.

There are other competing technologies that might come directly from the point of sale companies and probably more likely, just using your smartphone to perform the same function. Only time will tell which technology will work out. What do you think?
