Hypothesis. The packets are never queued, so there is no waiting time for none of them. No signal delay: The wireless devices are close enough one from another, so the signal delay time will be close to 0 (δ=0). The slot time length is 20 µs. The IEEE specification sets the standard length of every slot time in 20 µs,...

Propagation Delay Based Positioning Using IEEE 802.11b Signals
In such scenarios, IEEE 802.11 networks should offer coverage ranges of several kilometer, which leads to high propagation delay values. Thus, we analyze the influence of increasing propagation delay in the IEEE 802.11 MAC protocol. To carry out our analysis we present a mathematical model and simulation results. Throughput and delay limits of IEEE 802.11 - IEEE ... Throughput and Delay Limits of IEEE 802.11 Yang Xiao, Member, IEEE, and Jon Rosdahl, Senior Member, IEEE Abstract— The IEEE 802.11 protocol family provides up to 54-Mbps data rate, whereas the industry is seeking higher data rates. This paper shows that a theoretical throughput upper limit and a theoretical delay lower limit exist for the ... CSMA/CA - Clemson University
802.11 recommends 600ns as the switching time. Speed of light propagation : RF waves travel a distance of 100m in approximately 330ns. Thus, if two devices are 100m apart, then their carrier sensing and notion of slot boundaries may be 330ns apart. Slots must accommodate these delay...
The packets are never queued, so there is no waiting time for none of them. No signal delay: The wireless devices are close enough one from another, so the signal delay time will be close to 0 (δ=0).
