Overview This paper considers the feasibility of operating both IEEE 802.11b (Wi-Fi) and 802.16a (Wi-Max) networks in the same shared frequency band. A specific method using the "CSCC" (Common Spectrum Coordination Channel) etiquette protocol is studied and compared with earlier results on reactive interference avoidance algorithms. The CSCC concept is outlined, and its application to this particular 802.11 & 16 spectrum sharing problem is described in detail. The CSCC protocol is used to exchange control information on transmitter and receiver parameters, and hence to cooperatively adapt key PHY-layer variables such as frequency or power.
