Question:
You are designing a cellular system for a city of 750,000 using GSM @ 2% QoS..
a) The business case projects that penetration will be 10%. New studies have shown that the average daily traffic per subscriber will be 100 mEr. Calculate how many 3-sectored sites you will need to meet this traffic demand. Traffic behavior conforms to the Erlang B model.
You may assume the same GSM model to obtain the total number of channels.
There are 6 sectors with 8 time slots. 4 are used for control purposes.
b)The data rate for uplink for a communication system utilizing UMTS standard is around 25 Kbps. Calculate the spreading factor used for WCDMA technique.
B)Is the traffic calculation the only issue affecting the design of your system? Discuss
