Detailed explanation-1: -Explanation: The choice of channel assignment strategy impacts the performance of the system. Particularly as to how calls are managed, when a mobile user is handed off from one cell to another. Explanation: In a foxed channel strategy, each cell is allocated a predetermined set of voice channels.

Detailed explanation-2: -Channel Assignment strategies means to allocate the available channels to the cells in a cellular system Whenever a user wants to make a call request then by using channel assignment strategies their requests are fulfilled.

Detailed explanation-3: -Dynamic channel assignment : Dynamic channel assignment strategy reduces the probability of blocking and increases the trunking capacity of the system. These strategies need MSC to collect real time data.

Detailed explanation-4: -In a fixed channel assignment strategy. a. Each cell is assigned a predetermined set of frequencies. b. The call is served by unused channels of the cell.

Detailed explanation-5: -Fixed channel allocation scheme is preferred in situations where there are a small number of fixed users having a steady flow of uniform network traffic. The allocation technique is simple and so it can avoid the overhead of complex algorithms.
