METHOD AND APPARATUS FOR IMPROVING UNBALANCE OF SERVICE OF CELL EDGE IN WIRELESS LOCAL AREA NETWORK
First Claim
1. A method of an Access Point (AP) for improving unbalance of service at a cell edge in a Wireless Local Area Network (WLAN), the method comprising:
- monitoring a signal strength of a station for a continuous decrease of the signal strength over a predefined duration;
determining if the station is to handover, when there is the continuous decrease of the signal strength; and
decreasing a transmit power of the AP, when it is determined that the station is to handover.

Abstract
A method and apparatus for improving unbalance of service at a cell edge in a Wireless Local Area Network (WLAN). A method of an Access Point (AP) for improving unbalance at service of a cell edge in a WLAN includes monitoring for a continuous decrease of a signal strength of a station over a predefined duration, determining if the station is to handover, when the continuous decrease of the signal strength occurs, and decreasing a transmit power of the AP, when it is determined that the corresponding station is to handover.
