Abstract

A network controller of a communication network that serves one or more communication devices controls placement of one or more communication devices, such as a range extender, in the communication network. The network controller can control a communication device (e.g., a mobile device) and an access point serving the communication device to measure one or more wireless characteristics to generate first and second measurement information, respectively. The network controller can determine a placement score based on the first measurement information and the second measurement, and determine a placement location of the ranger extender within the communication network based on the placement score. The network controller can provide the placement location to the communication device and/or the range extender to indicate the placement location in which the range extender is to be positioned within the communication network.

Claims
