Air interface multiple access (MA) schemes to support broadband wireless communications (BWC) are presented. These encompass a mixture of core protocols, a number of network technologies, various bearer link types, and different traffic components in a common transport channel. We consider these schemes, which use a medium access control (MAC) virtual region (VR) concept developed to cope with diverse services and applications. We propose a dynamic broadband multiple access (DBMA) scheme to allocate and share the capacity. A model for this channel is then considered in further detail, and simulations results are presented. These feature the channel capabilities in supporting different types of traffic (i.e. VBR, UBR, CBR) and its level of performance when applying dynamic access permission probabilities. For a given system bandwidth, these minimise queue delays and packet dropping while maximising system capacity in the number of users supported for mixed traffic categories
