Mobile station power consumption a serious problem for Telcos

In UMTS, MS power consumption is a serious problem for wireless data transmission. The data bandwidth is significantly limited by the battery capacity. Therefore, power saving mechanisms are typically exercised to reduce power consumption. Most existing wireless mobile networks (including UMTS) employ Discontinuous Reception (DRX) to conserve the power of MSs. DRX allows an idle MS to power off the radio receiver for a predefined period (called the DRX cycle TD) instead of continuously listening to the radio channel.

Good.. Has this (DRX) been adopted ?

Yes, Telcos are using DRX feature to save bandwidth hence less power consumption by MS, inface Dynamic DRX has introduced.

Is there any any drawback of it?

How long are actually the DRX cycle / Possible active / Possible sleep times?
