Program for adjusting channel interference between access points in a wireless network
View Patent ↗The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
1. A computer program product recorded on a computer-readable medium, comprising:
logic for detecting that a first access point is using a radio frequency channel;
logic for detecting that a second access point is also using the radio frequency channel, the detecting logic including:
logic for receiving messages from the second access point; and
logic for maintaining indications of the transmit power levels of other access points including the second access point; and
logic, responsive to the indications of the transmit power levels of other access points maintained by the detecting logic, for instructing the first access point to adjust transmit power to decrease interference with the second access point detected to be using the radio frequency channel; wherein the first access point adjusts transmit power as instructed.
