Communications System Power Supply Designs
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. We discuss factors

RADIO BASE STATIONS FOR SECURE COMMUNICATION
48V voltage range for communication base stations For -48V system equipment, the required operating voltage range is -38.4V ~ 57.6V, but in fact we generally require the operating range -36V ~ -72V.

Why does the communication base station use -48V power supply?
The voltage of +48V and -48V is equal, but the current flow is not the same. +48V flow to 0V, V0 flow to -48V. So -48V voltage is the communication power supply standards of many countries.
