Base station equipment for communication systems

The basic base station equipment for digital mobile communications systems consists of amplifiers (AMP) to amplify the transmission and reception signals to desired levels, modems (MDE) to convert base band signals to high-frequency signals, speech processors (SPE) to convert voice signals to digital code strings, base station control equipment (BCE) that allocates radio channels and switches over channels with adjacent base stations, and the base station antennas (ANT).

Electrochemical energy storage systems are usually composed of

Electrochemical energy storage systems are composed of energy storage batteries and battery management systems (BMSs) [2, 3, 4], energy management systems (EMSs) [5, 6, 7], thermal management systems [8], power conversion systems, electrical components, mechanical support, etc. Electrochemical energy storage systems absorb, store, and release energy in the form of electricity and apply technologies from related fields such as electrochemistry, electricity and electronics, thermodynamics, mechanics, etc. Energy storage systems can eliminate the difference between the peaks and valleys in power demand between day and night and play a role in smooth power output, peak and frequency regulation, and reserve capacity.

Mobile base station power supply lightning protection

Mobile base stations are mostly built in high places, such as mountains, suburbs, and buildings.The base station antenna is often higher than the existing lightning protection air terminal of the building, which becomes the high incidence point of lightning strikes.Therefore, the lightning protection of mobile base stations should not only consider the protection of direct lightning strikes, but also consider the protection of lightning induction.In particular, the induction caused by the intrusion of lightning waves into the equipment through the power line.
