Since bandwidth of IEEE 802.11b is much larger than the bandwidth of IEEE 802.15.4 BAN, transmission of one IEEE 802.11b packet will take short time, and rest of active period can be used to exchange some command data between the bridge and access point of the ward room.

IEEE 802.11 Dictionary - WINLAB Home Page Consider the following two questions about IEEE 802.11 Standard: 1. Carrier Sense is provided by the physical layer, thus, when MAC layer get a packet to transmit. It will initiate a carrier sense mechanism, and it took >= DIFS time to determine that the channel is free, thus, at least we have a delay … Lectures 12: CSMA, CSMA/CD and Ethernet - MIT Eytan Modiano Slide 3 CSMA • Let τ = the maximum propagation delay on the channel – When a node starts/stops transmitting, it will take this long for all nodes to detect channel busy/idle • For initial understanding, view the system as slotted with "mini-slots" of duration equal to the maximum propagation delay – Normalize the mini-slot duration to β = τ/D

The 802.11 Application Framework provides a ready-to-run, easily modifiable real- time physical layer (PHY) and lower medium access control (MAC)The 802.11 Application Framework is available with the LabVIEW Communications System Design Suite, also referred to as LabVIEW Communications.

radio propagation delay and time required to switch the radio circuitry from receive to transmit mode. Thus, in order to reduce the slot time duration, either CCA time or turnaround time needs to be reduced.
