3G is finally here
WSIL News & Views October 11th. 2007, 12:53amI am glad to be writing the first post from a 3G device. Wireless is really great. It seems though that 3G is here maybe 7 years late. In any case I look forward to working with some MIMO enabled devices soon. Wsil let’s make this a reality!

What distinguishes a 3G device from a 2.5G device?

BTW, it appears that the manufacturer of your 3G phone is helping google make their “GPhone”.

Each G gets more and more incremental. 200 years from now, will they be celebrating 26G wireless communications?
“Now with 4% more G!”

Well, I was trying not to disclose the manufacturer of my device but, let me say, it is indeed HTC. They make phones for a lot of people - it doesn’t surprise me that google is jumping on. I had the experience of using google maps with the built in GPS for the first time. Cool!
Bob - 2.5G vs. 3G for a GSM device is easy since 3G supports CDMA whereas 2.5G just GMSK based TDMA (for voice) and the addition of EDGE with 8-PSK for data.
Steve - We get a new G about every 10 years. So you are about right, something like 25G would be appropriate. Not sure it is incremental. System spectral efficiency is certainly increasing by more than 4% - which is the real sell to service providers. For us though, 2G voice versus 3G voice, honestly can’t tell the difference. The data rate is higher though.

Well, between 3G and 2G there is a 50% G increase. Between 3G and 4G there is a 33% G increase, and so on. Eventually consumers will get leary of having so many G’s.
Marketing people will eventually just callet LG, Last Generation. And the one after that will be Super LG, and finally STITLG (Seriously, This Is The Last Generation).
Although I’m surprised how much marketers use engineering terms, like people know what they mean. CDMA, MIMO, etc. I guess it’s sexy to have confusing buzzwords on your box.

Wow, I actually wrote “callet” instead of “call it”. The engineering side of my brain is slowly taking over the rest.
