WebWi-Fi MultiMedia (WMM) is enabled by default. With WMM enabled, QoS prioritization and coordination of wireless medium access is on. With WMM enabled, QoS settings on the Access Point control downstream traffic flowing from the AP to client station (AP EDCA parameters) and the upstream traffic flowing from the station to the AP (station EDCA … Web802.11n introduced the Reduced Interframe Space (RIFS), a shortened gap between frames that was used to improve efficiency. HT devices were allowed to separate two frames with the RIFS (2 μs) instead of the much longer SIFS (10 …

Short Interframe Space (SIFS), is the amount of time in microseconds required for a wireless interface to process a received frame and to respond with a response frame. It is the difference in time between the first symbol of the response frame in the air and the last symbol of the received frame in the air. A SIFS time … See more Because most Software-Defined Radios use a host computer for processing, the SIFS imposes a difficult to achieve time constraint, as the latency for most SDR systems for the signal to traverse from the radio to the host and … See more • DIFS – DCF Interframe Space • RIFS – Reduced Interframe Space • PCF – Point coordination function See more WebThese compliance tests are used for transmitter and receiver measurements of IEEE 802.11n/802.11ac compliant device.
