What is a standard for electrical protection of communications facilities?

Standard for the Electrical Protection of Communications Facilities Serving Electric Supply Locations -- General Considerations Amendment: New Annex J- Guidance for Determining the Ground Potential Rise and Induced Voltages for the Design of Communications Installations at Electric Supply Locations

Why do baseband units need electrical protection?

Figure 6. Baseband Units need electrical protection at the power circuits, processors, and I/O lines. The BBU links the AAS and the wireline infrastructure, encoding transmissions and decoding received signals while processing data from calls and transmissions.

How do you support a base station?

Support the base station by: Providing a fast-acting fuse on the battery circuit for overload protection. Monitoring battery temperature rise to ensure battery safety. Placing surface mount thermistors on the battery pack modules. Protecting the battery pack modules from overcharging.

What does a base station do?

The base station is a fixed transceiver that acts as the primary transmission and reception communication hub for wireless devices. The base station modulates baseband information and transmits it to mobile devices. Base stations also receive mobile device transmissions, modulate them, and send them to the wireline infrastructure.

How do you support a base station when AC power is interrupted?

A backup battery (block 5) is one of the best ways to support the base station when AC power is interrupted. Support the base station by: Providing a fast-acting fuse on the battery circuit for overload protection. Monitoring battery temperature rise to ensure battery safety.

What is a 5G base station?

The base station connects to all wireless devices attempting communication within that geographic or coverage area. A 5G base station will include advanced, active antenna systems populated by numerous antennas in multiple input-multiple output (MI MO) configurations. These antennas provide: More efficient delivery of RF power. Figure 1.
