ตัวอย่างที่ 3 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 60 kHz. 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, (b) the number of channels per cell, (c) traffic intensity of each cell, (d) the maximum carrier traffic, (e) the total number of users that can be served for 2% GOS, (f) the number of mobiles per unique channel, and (g) the theoretical maximum number of users that could be served at one time by the system.
