Abstract
Systems and methods of enhanced real-time communications between WiFi devices. In one embodiment of the present invention a method for enhanced payload protection in a WiFi system includes transmitting multiple copies of data packets in successive frame body transmissions. In another embodiment, a method for enhanced communications over a WiFi link includes examining a unit ID packet to determine a destination of a data payload when errors are detected in IP and/or MAC headers. If a destination is determined, the packet is corrected and forwarded to the device based on the unit ID determination. In another embodiment, a method for enhanced real-time communications in a WiFi network includes establishing a communications frame that includes an active timeslot, preferably based on U-APSD, for a WiFi device to use for transmission of successive audio data packets transmitted between the WiFi handset and AP.
