A certain city has an area of 1,300 square miles and is covered by a cellular
system using a seven-cell reuse pattern. Each cell has a radius of four miles
and the city is allocated 40 MHz of spectrum with a full duplex channel
bandwidth of 60kHz. Assume a GOS of 2% for an Erlang B system is specified.
If the offered traffic per user is 0.03 Erlangs, compute
a) The number of cells in the service area (A: 31 cells)
b) The number of channels per cell (A: 95 channels/cell)
c) Traffic intensity of each cell (A: 84 Erlang/cell)
d) The maximum carried traffic (A: 2604 Erlangs)
e) The total number of users that can be served for 2% GOS (A: 86,800 users)
The number of mobiles per unique channel (A: 130 mobiles/channel)
9) The theoretical maximum number of users could be served at one time.
