By the way that was my class number that's erased. 

2. A digital cellular telephone system is required to work at a bandwidth efficiency of 4 bits/second/Hz in order to accommodate sufficient users to make it profitable. What is the minimum Eb/NO ratio that must be planned for in order to ensure that users on the edge of the coverage area receive error-free communication? If the operator wishes to double the number of users on his existing network, how much more power must the base-station and handsets radiate in order to maintain coverage and error-free communication? [hint: The Shannon Hartley theorem can be written as: C/B = log2[1 + EbC/NOB] ] %3D
