Abstract—The importance of communication in an urban city is so obvious. This is because of the interrelationship between the development of city’s economic and effective telecommunication services-like GSM. This research work looked at means of providing an urban city, Abuja as a case study, an improved 2.5G GSM network that will provide good speech quality, spectral efficiency, support ranges of many features, low terminal and service cost. The work was done asof 2004/2005 year with a lot of planning, design calculation of all the transmission planning using a mathematical model and analysis for the link budget. With the analysis of the estimated result carried out, it was concluded that total call check was 100% with 90% and 10% of prepaid and postpaid subscribers respectively. The capacity requirement for the number of subscriber was 10,500 and traffic analysis done showed that traffic per cell for the network will be 22 traffic control channel with a 2% grade of services. Base on this traffic evaluation, 14.9 Erlang gave an equivalent of 596 subscribers (i.e., 7 sites). Due to the topography of the link between site A to site H, design of a repeater station to amplify the radio signal across each others was considered and adding the design.
