802.11 slot time propagation delay

By Admin

The IEEE 802.11 standard deﬁnes the slot time σas the time necessary to allow for the detection of the transmission of a packet from any station. Speciﬁcally, it is the sum of the RX-to-TX turnaround time, the energy detection time, and the propagation delay [17]. The slot time used in the standard for frequency

It accounts for the propagation delay, for the time needed to switch from the receiving to Manuscript received February 9, 1998. The associate editor coordinating ... Propagation Delay SIFS Slot Time DIFS 8184 bits 272 bits 128 bits 112 bits + PHY header IEEE 802.11 Wireless Access Method and Physical Specification slots. The length of the slot should be equal to the total of the "es detect time"+"Rx-Tx switching and Tx turn-on time"+"medium propagation delay time". Increase of the switching time will cause a severe effect on the total throughput under high load condition, and will decrease the response time. Performance Analysis of IEEE 802.11 Distributed ...

IEEE 802.11 protocol allows DCF (Distributed Coordination Function) and PCF (Point Coordination Function) to access the medium. This paper discusses the analysis of PCF traffic and DCF traffic over a BSS network. A Glomosim¹ simulator was used to simulate the PCF environment.

The slot time for a DSSS PHY (20 ms) is defined as the sum of the receive-transmit turnaround time and the energy-detect time including any propagation delay.
