14.4 An analog cellular system has a total of

33MHz

of bandwidth and uses two

25-kHz

simplex (one-way) channels to provide full duplex voice and control channels.\ a. What is the number of channels available per cell for a frequency reuse factor of (1) 4 cells, (2) 7 cells, and (3) 12 cells?\ b. Assume that

1MHz

is dedicated to control channels but that only one control channel is needed per cell. Determine a reasonable distribution of control channels and voice channels in each cell for the three frequency reuse factors of part (a).\ 14.7 / KEY TERMS, REVIEW QUESTIONS, AND PROBLEMS 431\ 14.5 A cellular system uses FDMA with a spectrum allocation of

12.5MHz

in each direction, a guard band at the edge of the allocated spectrum of

10kHz

, and a channel bandwidth of

30kHz

. What is the number of available channels?
