How much power does a cellular base station use?
This problem exists particularly among the mobile telephony towers in rural areas, that lack quality grid power supply. A cellular base station can use anywhere from 1 to 5 kW power per hour depending upon the number of transceivers attached to the base station, the age of cell towers, and energy needed for air conditioning.
How do cellular base stations work?
Most transceivers in the cellular base stations are run by 48 VDC to charge the batteries and power the communication equipment. The air conditioning of the base station runs at 220 VAC. These base stations can be powered by two types of diesel generators.
How does a telecommunications DC power system work?
A simplified diagram of a typical telecommunications DC power system. When power from the grid is lost, the diesel generator is designed to start automatically providing AC power to the DC port system. The ATS synchronizes voltages from different sources to the equipment.
What voltage does a DSL power system supply?
The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).
Why do cellular base stations need maintenance?
Cellular base stations use power without any interruption and also needs maintenance. The increase in demand of power base stations from Indian telecommunication industry is a big challenge, especially in rural India.
What is a multi-output power supply design?
Multiple output designs may also employ a complex regulation scheme which senses multiple outputs to control the feedback loop. Voice-over-Internet-Protocol (VoIP), Digital Subscriber Line (DSL), and Third-generation (3G) base stations all necessitate varying degrees of complexity in power supply design.
