What does a 42 volt power supply mean?
42V. It means that if the voltage drop is more than 6V, the ICT equipment will be protected. It can be seen that when the length more than 120m in the 4G system and the length more than 70m in the 5G system, the ICT equipment will be off because the low voltage protection of the power supply system.
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.
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).
What type of generator does a base station use?
The air conditioning of the base station runs at 220 VAC. These base stations can be powered by two types of diesel generators. The first is the conventional type where 220 VAC is converted to 48 VDC to charge the batteries and power the communication equipment.
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.
