BASE STATION ARCHITECTURE FOR GREEN WIRELESS COMMUNICATIONS
The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage
This study presents an overview of sustainable and green cellular base stations (BSs), which account for most of the energy consumed in cellular networks. We review the architecture of the BS and the power consumption model, and then summarize the trends in green cellular network research over the past decade.
The authors provide an overview of the existing approaches of power management for wireless base stations, which include base station power control through beamforming, base station assignment based on the dynamic connectivity patterns between mobile units and base stations, smart mode switching, and cooperative relaying.
In radio communications, a base station is a wireless communications station installed at a fixed location and used to communicate as part of one of the following: a wireless telephone system such as cellular CDMA or GSM cell site. Base stations use RF power amplifiers (radio-frequency power amplifiers) to transmit and receive signals.
Cellular network operators attempt to shift toward green practices using two main approaches. The first approach uses energy-efficient hardware to reduce the energy consumption of BSs at the equipment level and adopts economic power sources to feed these stations.
