An Overview of Multi-Operator Global Systems for Mobile Communications Base Stations in the Context of Nigerian Telecommunication Sector
##plugins.themes.bootstrap3.article.main##
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.
