26.0 What is Power Control and what is it used for?
Power Control refers to strategies and procedures used or required, in order to adjust, correct and manage, as dynamically as possible, the transmitted power from either the Handset or the Base Station.
Power Control is required in CDMA systems, in part, to resolve the Near-Far problem.
There are other reasons for which Power Control is required in CDMA systems:
- Maintain a Satisfactory Voice Quality for most users
- Increase overall system Capacity while maintaining an acceptable voice Quality for customers.
- Reduce the average Transmit power from handsets (for Reverse Link
applications), or from cells and sectors (for Forward Link Power Control
applications.)
