Abstract

A system and method of determining adaptive wireless coverage configurations is disclosed. One or more network devices receive wireless signals from a wireless device at respective signal strength values that are above a minimum threshold. The network devices are identified as a first subset of network devices. Additionally or alternatively, one or more network devices transmit wireless signals that are received by the wireless device at respective signal strength values that are above a minimum threshold. The network devices are identified as a second subset of network devices. Based on the number of network devices in the first subset of network devices and/or the number of network devices in the second subset of network devices, a wireless coverage configuration corresponding to a location associated with the wireless device is modified.
