As various wireless technologies and application demands for more and more bandwidth, dynamic channel allocation in multiple bands has become an attractive research direction. In this paper, the authors propose several channel allocation policies for various types of user profiles under various fluctuation traffic loads in dual-band multi-cell environments. The considered policies include fixed allocation with admission control, reallocation on hourly basis, and reallocation on hourly basis with forced dropping. Performance comparisons of the system utility and the band utilization with various policies are investigated. Also, how the bandwidth concentration ratio is balanced between the operator's revenue and users' satisfaction under a selected policy is illustrated.
