We all see references to 2G, 3G and 4G wireless systems and sometimes we see references to 2.5G as an in between system, but now I am seeing 2.75G, 3.75G and even 3.9G (why not just say close to 4G or just under 4G). How can you have a half or three quarters of a generation? I guess if you just base it on data rates, maybe we can get these fractional generations.
What caught my eye was the Asus announcement that they are adding 3.75G wireless to their new laptops due out in October 2008. They state download rates of 7.2 Mbit/s and upload rates of 2 Mbit/s which is very good, but it is really just HSUPA technology so why not just call it that. Maybe it is not as elegant as 3.75G.
It took a very long time to develop systems from 2G to 3G, so I can see why we have the 2.5G but anything beyond that is getting carried away in my book. But I guess it is progress as long as the numbers keep getting larger!
