The wireless metropolitan area networks (WMANs) based on the 802.16 technology have recently gained a lot of interest among vendors and ISPs as the possible next development in wireless IP offering and a possible solution for the last mile Access problem. With the theoretical speed of up to 75 Mbps and with a range of several miles, 802.16 broadband wireless offers an alternative to cable modem and DSL, possibly displacing these technologies in the future. We discuss implementing security in wireless MANs with the PKM protocol that is used in 802.16 for key management and security associations management. Since device certificates are defined by the IEEE 802.16 standard, we briefly cover the issue of certificates and certificate hierarchies.
