Appendix C

RRM TPC Algorithm Example

Chapter 6, “Designing Radio Management,” explained how the transmit power control (TPC) algorithm automatically adjusts the transmit power level of access points (APs) in a radio frequency (RF) group. If you decide to enable TPC in a wireless network, you might like to have a better understanding of how TPC chooses the values it assigns to the APs. This appendix presents a real-world example that you can follow as TPC does its job.

The example scenario is one of a large classroom where a high density of users normally exists. There are ten APs in the room, each mounted on the ceiling and connected to a directional antenna pointing downward. The design goal was to create relatively small cells to constrain ...
