The number of users of the Global System of Mobile Telecommunications (GSM) in the world is growing at an exponential rate; with more than 146 million users in Nigeria alone. There is a continuous need to install GSM supporting infrastructure to take care of increasing users in terms of service delivery. As at December 2013, the number of base tran...

However, there is no work on performance evaluation of a multi-operator GSM base station, which is the focus of this project work [1]. Deliberate effort should be made to overcome some of the major deterrents discouraging some operators in Africa from sharing infrastructure with other operators, which includes; utilization of different supplier in the value chains, utilization of Inferior equipment and monopolistic Behaviour among well-established operators. ...
The number of users of the Global System of Mobile Telecommunications (GSM) in the world is growing at an exponential rate; with more than 146 million users in Nigeria alone. There is a continuous need to install GSM supporting infrastructure to take care of increasing users in terms of service delivery. As at December 2013, the number of base transceiver stations (BTS) was 28,289; whereas by projection Nigeria needs additional 33,000 BTSs by 2018. However, there are serious technical challenges militating rapid installation of base stations, such as environmental congestion, high capital expenditure (CAPEX), multiple regulations and taxation, anti- competitive practices among a number of operators. In order to address these challenges, infrastructure sharing has been proposed, and adopted by some GSM operators. This paper presents an overview of GSM infrastructure sharing.
... The tower height was fixed at 55m, the wind speed at 15m/s normal to the surface of the tower and tower equipment, and the antenna tilt set at 0 0. It was observed that as the number of mobile network operator increase the wind loading increase linearly. Figure 3 Equipment placement on tower layout ( Ehiagwina, 2015) Ehiagwina USEP: Journal of Research Information in Civil Engineering, Vol.14, No 4, 2017No 4, et al 1793 The position of tower equipment for different operators up to six (6) operators are shown in Tables 2. How does the tilt angle of the antenna affects the tower wind loading for a shared mobile cellular tower? ...
In order to overcome challenges militating against the rapid deployment of mobile cellular infrastructure, it is technically and economically crucial for a number operators to share mobile cellular infrastructure such as power supply, base station (BTS) cabin and telecommunication tower. For an efficient tower sharing, an analysis of tower’s wind loading and the tower bending moment have to be performed. In this work, we performed wind loading analyses for a multi-operator mobile cellular network. It was verified that as the number of operators increase, the wind loading value also increases. This work further observed that as the value of the antenna tilt increases, the tower wind loading proportionately increases. However, as the wind direction deviates from the normal, the wind loading reduces slightly. Finally, for six mobile cellular network operators, with total tower height set at 55m, the bending moment at a rare wind speed of up to 67m/s was evaluated to be 10 , 260 kNm . It is vital that the bending moment of the telecommunication tower be lesser than the manufacturer’s specified tower bending moment limit. The results obtained from this research can be used to tighten tower survivability criterion. It will also serve as a useful tool to mobile cellular equipment designers and installers.
