Collision detection in HIPERLAN

The collision detection (CD) is an interesting feature which provides optimal performance to radio LANs such to make the latter comparable to wired LANs (e.g. Ethernet). The European HIPERLAN 20 Mbps standard is the natural environment for this implementation, since this standard involves the most powerful physical base and the most multivalent architecture for radio LANs. We describe one possible way to detect collision in a radio LAN, based on the so-called Comb strategy which is very similar to collision detection. This technique is developed and implemented in LAURA Esprit project
