Power Control Vs Rate Control in CDMA
EVDO is just not bothered about controlling and varying power ouput in the forward link. The output power is constant unlike in IS-95/1x.
IS-95/1x base stations vary the power and give more power to disadvantaged users who are in poor RF conditions.
If a user is in poor RF conditions, instead of varying the power output,EVDO base stations vary the data rate offered to the user. They reduce the data rate keeping the power constant.
