In the system in Exercise 11.1, what if, instead of increasing the number of base stations to achieve full coverage, a higher transmit power is used? Compare the power for the 5 and 10 Mbps systems to the 1 Mbps system.

Exercise 11.1

In a cellular system the path gain from an access port to a terminal follows the expression G(r) = C − 35log10(r) (dB). The system is designed to provide digital wireless access at a minimum data rate of 1 Mbps. At full power at the design range, 5 km, where the system achieves full coverage, the signal to noise ratio, Eb/N0, is 5 dB. A single channel of 5 MHz bandwidth is used. Assume the system to be noise limited. a) Determine the area coverage (in percent) at 2 Mbps, 5 Mbps and 10 Mbps minimum data rate. b) How many more access ports are required to achieve full coverage for the data rates in (a) if the transmit power is constant?
