Rework Example 9.11 with everything the same except assume SIRdB; min= 10 dB.
EXAMPLE 9.11
Suppose that a cellular system uses a modulation scheme that requires a channel spacing of 25 kHz and an SIRdB;min = 20 dB for each channel. Assume a total bandwidth of 6 MHz for both base-to-mobile (forward link) and mobile-to-base (reverse link) communications. Assume that the channel provides a propagation power law of α = 3:5. Find the following:
(a) the total number of users that can be accommodated within the reuse pattern,
(b) The minimum reuse factor N,
(c) the maximum number of users per cell, and
(d) the efficiency in terms of voice circuits per base station per megahertz of bandwidth
