Abstract

A method and apparatus improve throughput of a forward communications link between a source device and a reception device. The method includes receiving a beacon frame from the reception device, determining a link quality associated with the forward communications link based on information obtained from the received beacon frame, and determining an optimum transmission rate based on the signal strength. A signal is transmitted from the source device to the reception device using the optimum transmission rate.
