PPT-1 Wireless Medium Access Control (MAC)

Romit Roy Choudhury Wireless Networking Lectures University of Illinois at Urbana Champaign 2 Wired Vs Wireless Media Access Both are on shared media Then whats really the problem 3 The Channel Access Problem. CMAC exploits concurrent wireless channel access based on empirical power control and physical interference models Nodes running CMAC estimate the level of interference based on the physical SignaltoInterferenceplus NoiseRatio SINR model and adjust Its wireless design and small size make it easily adaptable for a variety of access control requirements Typically the AP4 is used to control a door strike barrier gate automatic gate or automatic door operator The AP4 contains a highgain UHF receiv Sublayer.
