OPTIMIZING THE ULTRA DENSE 5G BASE STATIONS IN URBAN OUTDOOR

Battery inspection methods for communication base stations

Aiming at the voltage and current measurement for battery banks in mobile communication base station, according to voltage characteristics of wide common-mode range, three methods including sampling with resistors, converting with analog optical coupler and differential subtractor based on amplifier are presented.For bi-directional current characteristic, both single and double amplifier methods are discussed respectively.Also, all the methods mentioned above are analyzed.

Solar power supply equipment for communication base stations

Communication equipment usually uses -48V DC power supply, and the electricity generated by photovoltaic power generation systems is also DC power, so the photovoltaic power generation system is combined with the communication base station, and the electricity generated by the photovoltaic system is used to directly power the communication equipment, reduce the consumption of city electricity, and achieve the effect of energy conservation and emission reduction.

What does 22 degree outdoor power supply mean

This means that the power supply can “start-up” or be “turned-on” with an ambient temperature as low as -40°C (below the -20°C spec) and deliver 100% of its rated power, however, the power supply’s output regulation, hold-up time, ripple & noise, and other specifications cannot be fully guaranteed until the power supply warms up to at least -20°C.
