Sifs wifi
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 • EIFS – Extended interframe space See more WebThese compliance tests are used for transmitter and receiver measurements of IEEE 802.11n/802.11ac compliant device.
