Mobile Networks Power Systems Training: Like all wireless communication technologies, cellular networks use electromagnetic waves to send information. Just as your radio has different frequency bands, so do wireless communications technologies have specific frequency bands in which they operate.
If all wireless communication attempted to use the same frequency, there would be too much noise and interference for clear communication. As such, the FCC regulates which frequency bands can be used by whom, and cellular carriers each have a specific band that they’re allowed to operate within (for example, Verizon is in the 746-757 MHz and 776-787 MHz bands).
The prime power infrastructure for processing electromagnetic waves is the cell tower. Network operators split up coverage areas into cells. Each cell has a cell tower that operates at a different frequency than adjacent cell towers. In a hexagonal arrangement, for instance, this means only seven different frequencies are needed to ensure that the same frequency isn’t used in adjacent cells.
The base station at the center of each group of cells functions as the hub for those cells — not of the entire network, but of that individual piece of the network. RF signals are transmitted by an individual phone and received by the base station, where they are then re-transmitted from the base station to another mobile phone. Transmitting and receiving are done over two slightly different frequencies.
Base stations are connected to one another via central switching centers which track calls and transfer them from one base station to another as callers move between cells; the hand off is (ideally) seamless and unnoticeable. Each base station is also connected to the main telephone network and can thus relay mobile calls to landline phones.
However, base stations have accounted for almost 60 percent of the total mobile network power consumption while 20 percent is consumed by mobile switching equipment and around 15 percent by the core infrastructure.
Low efficiency in the RF and base band processing stages is the main reason for the base station’s relatively high power consumption.
The heat generated by inefficient operation must also be removed, typically by air conditioning, which adds further to the base station’s overall power consumption.
Fortunately, the technologies that power the networks continue to evolve and advance along with the equipment consumers use to connect with them.
The electric grid and dirtier diesel fuels have been the main power source for mobile networks. But on the horizon are small transmitters called small cells, which will provide much of the capacity for future networks.
These small cells might be tethered to small wind generators or solar panels and batteries, or even include their own built-in power sources and batteries.
