In this paper, a two-tier cellular wireless network is characterized by overlapping the service area for managing the new calls users having different mobility speed. The overlapping property of the two-tier system provides the advantages that share the traffic load to improve the efficiency of new calls subscriber with guard channels in cell to handle the handoff calls. Using Guard channels, the authors' strategy have the prioritization to the handoff calls. Micro cells are used to provide the services to slow-speed, high-intensity traffic area users and macro cells are overlaid over more than one micro cell cater mainly to lower density, high-speed users.
