Abstract

The present disclosure provides for a user equipment (UE) for use in a wireless computer network that has multiple wireless access points (APs). The UE can include a wireless transceiver that communicates with the computer network, a link quality assessor that assesses the quality of the communication link between the wireless transceiver and the first selected wireless AP, a link quality forecaster that forecasts a predicted future quality of the communication link as a function of the past quality of the communication link, and an AP switching module that 1) initiates an AP link quality scan to determine a second selected AP when the forecasted link quality falls below a first link quality threshold and 2) switches to the second selected wireless AP when the forecasted link quality falls below a second link quality threshold.
