KDDI is planning Ultra 3G


EVDO – Next Generation doesn’t sound sexy. That perhaps that explains why KDDI is staying away from the EVDO mumbo-jumbo, and is calling its post 3g network, The Ultra 3G. (No relation to Ali-G!) The Japanese giant along with rest of the CDMA faithful hopes to complete the next-generation CDMA 2000 wireless standard by mid-2007, which will boost speeds to 100-to-1000 Mbps down and 50 Mbps up. “Third Generation Partnership Project 2” (3GPP2) will allow carriers to marry a whole slew of technologies – today’s 3G mobile phones, wireless LAN, IEEE 802.16e, new wireless systems, and even ADSL and FTTH wired access media using a technology called, “IP Multimedia Subsystem/Multimedia Domain (IMS).” There is a lot of talk about IMS these days. KDDI says it is on target to rollout EVDO Rev A service by end of 2006 – where speeds get goosed up to 3.1 Mbps down and 1.8 Mbps up.

Note that they hope to have the standard worked out by 2007, not the technology. HSDPA as a standard goes back to at least 2002, but you won’t see it deployed before 2006 . . . Achieving very high throughputs requires more spectrum than one can generally license. Getting an efficiency of 1 bit/Hz is considered quite excellent. At that efficiency you would need 100 MHz of spectrum to offer 100 Mbps service. I can’t think of an US carrier that has 100 MHz of spectrum in a given market even if you count 2.5 and 2.3 GHz licenses.

but when that happens. i think these technologies are going to happen, but i would temper my expectations
