Abstract:
1. A wireless communication device comprising: a transceiver configured to receive a signal on a channel; a medium access control device configured to determine a parameter, wherein the parameter is a transmission error rate of the signal or a quality measurement of the signal, and wherein the medium access control device is configured to generate a control signal based on (i) the parameter, and (ii) a signal-to-noise ratio of the signal; a first module configured to, based on the control signal, determine whether an operating environment of the wireless communication device is a rich-scattering environment or a line of sight environment, wherein the signal is received at the wireless communication device via multiple independent transmission paths in a rich-scattering environment due to reflections of the signal, and wherein the signal is received at the wireless communication device via a single transmission path in a line of sight environment; and a second module configured to adjust a bandwidth of the wireless communication device based on the operating environment as determined by the first module, wherein the second module is configured to (i) decrease the bandwidth for a rich-scattering environment, and (ii) increase the bandwidth for a line of sight environment.
