Chapter 2 Part 1 - Wireless Networks
Q 1) Using the following data for a GSM 1800 network calculate:
(1) average busy hour traffic per subscriber. (2) Traffic capacity per BTS (3) required member of base stations per zone (4) The hexagonal cell radius for the zone.
Subscriber usage per month = 150 minutes
Days per month = 4
Busy hour per day = 06
Allocated spectrum = 4.8 MHz
Frequency raise plan = 4/12
RF channel with = 200 KHZ (full rate)
Present number of subscribers in the zone = 50,000
Subscriber growth = 5% per year
Area of the zone = 500 km2
Initial installation bused on a four year design
capacity of a base station (transceiver) (BTS) = 30 Erlangs
Traffic capacity of a GSM cell at 2% Gos (using Erlang B table) = 8.2 Erlangs
