Detailed explanation-1: -Explanation: Frequency reuse is a technique of reusing frequencies and channels within a cellular system to improve capacity and spectral efficiency. Explanation: Handoff is the process of changing the channel associated with current connection while a call is in progress.
Detailed explanation-2: -Answer: a. Explanation: Frequency reuse is the process of using the same radio frequencies on radio transmitter sites within a geographic area.
Detailed explanation-3: -(C) “Number of base stations is reduced” is not an advantage of using frequency reuse. Advantage of using frequency reuse : Frequency reuse is a strategy for increasing capacity and transmission range by reusing frequencies and channels inside a cellular system.
Detailed explanation-4: -What is a frequency reuse factor for N number of cells in a system? Explanation: The frequency reuse factor is defined as 1 over the number of cells in the cluster of the system (N). It is given by 1/N since each cell within a cluster is only assigned 1/N of the total available channels in the system.
