IEEE 802.11p supports 8µs while 11a supports 4µs. • Guard time interval is 1.6µs in 802.11p while 11a has 0.8µs. 802.11p protocol stack-PHY, MAC Fig-2:802.11p protocol stack The figure-2 depicts entire DSRC/WAVE protocol stack. IEEE 802 .11 Terminology Station (STA) Architecture (cont’d): Ethernet-like driver interface supports virtually all protocol stacks Frame translation according to IEEE Std 802.1H IEEE 802.3 frames: translated to 802.11 Ethernet Types 8137 (Novell IPX) and 80F3 (AARP) encapsulated via the Bridge Tunnel encapsulation scheme A Technical Tutorial on the IEEE 802.11 Standard 18 July, 1996 BreezeCom copyright BreezeCOM 1997 Page 5 IEEE 802.11 Layers Description As any 802.x protocol, the 802.11 protocol covers the MAC and Physical Layer, the Standard currently defines a single MAC which interacts with three PHYs (all of them running at 1 and 2 Mbit/s) : The huge advantage with this is that it requires no batteries and the cost per unit is very low. The initial investment might be high, but after that it doesn't really matter if your tracking 500 units or 5,000 units. And since it's RFID, you can protect just about anything without a huge engineering effort.

Wi-Fi: 802.11 Wireless LANs Here, we provide an overview of the 802.11 wireless LAN standards, Wi-Fi and hotspots. We concentrate on understanding the variations of 802.11, the frequency bands they operate in, bit rates to be expected, propagation issues, and Wi-Fi 6, which is 802.11ac, the first to implement OFDMA. – RNC (Radio Network Controller) (equivalent to GSM BSC) • Responsible for radio resource management and control of the Node Bs. • Handoff decisions, congestion control, power control, encryption, admission control, protocol conversion, etc. Telcom 2720 6 UTRAN architecture • UTRAN contains several RNSs • Node B can support FDD or TDD 2006-11-06 basis of MAC protocol in IEEE 802.11 WLAN, which allows only one user to utilize radio channel at a certain time.
