Analyze the Types of Communication Stations

There are main two types of communication networks: cellular networks and wired networks. Each type contains different sector which discussed in this chapter, also corresponding energy consumption models are introduced. Over 90% of the wireless network power consumption is part of the operator’s operating Exchange (OPEX), which includes the Mobile Switching Centers (MSCs) and Radio Base Stations (RBSs). The key elements are the highly deployed radio base stations because the total number of base stations is exceptionally high. There are approximately more than 4 million installed Base Transceiver Station (BTS) cabinets in the world today with relatively high energy consumption, about 60 TWh per year. Furthermore, the corresponding CO2 emissions are around 30 Mt. In general terms, access radio equipment is responsible for about 80% of energy consumed by a cellular network. Main components of BTS are presented. Sectors of wired networks and energy consumption rate of each sector are discussed.
