Clark,

Any surprise the only way to increase the data rate for these systems is to add together the timeslots, using them up all the more quickly? I've spit this opinion out many times, but couldn't really substantiate it.

PS. Welcome back.

Clark: Who promised those bit rates? The answer is nobody.

It has been mentioned many times before on these threads that when systems go commercial they will be far lower. The natural evolution of technology will probably see the bit rate go higher over time. I mentioned some time ago, here, that there was too much hype about 3G's 2Mbps - because that is a load of crap too. The first commercial systems will be far lower at only a few hundred bits per second. I bet nobody will get more than a practical 170kbps in any 3G cdma system when launched, it will soon rise to the touted 384kbps but that would be when stationary, etc.

Anyway, why should I moan - my much loved IT department replaced my 56.6 laptop modem with a 28.8kbps (nice move guys!). Jeez, I have even posted here via GSM at 9.6kbps (wasn't as bad as I thought it would be, downloading the porn was a bit frustrating though ;-)

In the case of HDR, the channel is not symetrical, so the sending is more like full rate IS-95. Receiving data on HDR into the device is the same pwoer as it used to be on any rate of IS-95.

the MSM chip consumes approx the same pwoer in any of these modes and th RF radio is the same on used on IS-95, so the battery rates should be similair to the normal voice talk times on CDMA as present.
