Question

Q6. In a cellular system, frequency reusing improves the capacity and spectral efficiency. a) Explain the following terms. (i) hand-off process (ii) co-channel interference. b) Derive the relationship between any two nearest co-channel cell distance \"D\" and the cluster size \"N\". Assume each cell has a hexagonal shape. c) A total of 50 MHz bandwidth is allocated to a FDD cellular system with two 22 KHz simplex channels to provide full duplex voice and control channels. Compute the number of channels available per cell if the system uses (i) 4 cell, and (ii) 7 cell reuse techniques. Also, assume 1.3 MHz of spectrum is allocated to control channels. Give a distribution of voice and control channels.
