Base stations must operate 24/7/365. Core energy consumption comes from the main equipment (RRU/BBU), air conditioning, and power supply systems (switching power supplies and batteries). My understanding is that they used to use negative 48V DC power, i. 24 2-volt lead acid cells in series, with positive grounded. Today, it's possible to find these telecom batteries, like those made by Victron. Base stations are required to enable mobile phone communication, including calls and data transfer. They consist of different electronic components and antennas and can be located on masts, on rooftops, or on the outside or inside of buildings. Backhaul: Although this is not strictly part of the cellular base station, it interfaces directly with it to. Power Supply: The power source provides the electrical energy to base station elements. It often features auxiliary power supply mechanisms that guarantee operation in case of lost or interrupted electricity, during blackouts. But like all power, there are those who want to.
