Abstract

A base station (104) is configured to reduce interference with other base stations (106) and/or devices in a multi-cell wireless network. The base station includes a wireless interface (118), detector (116) and controller. To reduce interference, the wireless interface may provide services to a first wireless communication device (108A) (WCD) using a pilot signal (932) emitted from the base station 104 at a reduced power level. In the reduced pilot signal mode, when the detector detects a second WCD (108B) within the base station's service area, the controller increases the pilot signal's power level above the reduced power level in order to establish communications with the second WCD (108B). Upon successfully connecting to the first and second WCDs, the base station (104) may again reduce the pilot signal's power level to reduce interference with other base stations or wireless devices.
