Abstract
Systems and methods that provide wireless communications are provided. One or more of the systems and methods may include, for example, selecting a lower data rate or a higher data rate based upon at least an evaluation of the operating conditions of a radio network. The evaluation may include, for example, computing a weighted signal strength measurement in which the weighting gives emphasis to the lower signal strength measurements of fading radio frequency signals.
