    摘要: Various embodiments directed to a radio frequency (RF) environment aware wireless communication device to analyze interference characteristics of at least one interferer in the presence of interference in an RF communications channel and to selectively perform one or more adaptation mechanisms for adjusting properties of a communications protocol based on the interference characteristics of the at least one interferer. The interferer may comprise a non-communicating device (e.g., microwave oven) or a communicating device (e.g., baby monitor, cordless phones, Bluetooth device, etc.) operating within or in the vicinity of a wireless network. The adaptation mechanisms may comprise contention window control to backoff and defer transmission according to a contention window and to leave a backoff counter of the contention window unchanged if the interference is determined to be non-802.11 interference. The adaptation mechanisms may comprise aggressive transmission to transmit over the interference. Other embodiments are described and claimed.

    摘要: When a wireless communications device determines that a microwave oven or other source of periodic interference is operating nearby, the device may rapidly increase the size of its contention window to reduce the number of retries that it attempts during the period of interference. Similarly, it may rapidly decrease the size of the contention window during the periods of non-interference. In some embodiments, the maximum size of the contention window derived during periods of interference may be sized to assure enough time for successful completion of at least one transmission during the next period of non-interference.
