Question
(a) Given a cellular system in which one-way bandwidth of the system is $12.5\text{ GHz}$, channel spacing is $30\text{ kHz}$ and guard band at each boundary is $10\text{ kHz}$. If cellular area is $6\text{ km}^2$, frequency reuse factor is $7$ and $21$ channels are used for control channels. [10]
Calculate :
(1) The total number of channels per cluster.
(2) The number of data channels per cluster.
(3) The number of data channels per cell.
(4) The system spectral efficiency in channels/$\text{MHz/km}^2$. [10]
(b) Explain the concept of CDMA and FDMA. [10]
