ABSTRACT:
Methods and systems for selecting data rates are described in a wireless network. The distance between a client and a base station serving the client device is determined. Based on that distance, a minimum threshold data rate is selected such that a larger distance corresponds to a higher minimum threshold data rate and a smaller distance corresponds to a smaller minimum threshold data rate. An actual data rate, not less than the minimum threshold data rate, is then selected, and signals are transmitted between the client device and the base station at the actual data rate. The actual data rate may be increased if there exists unused available bandwidth in the network. Events such as a change in distance or a timer expiring may result in a recalculation of the minimum threshold data rate.
