How does a base station work?
Base stations typically have a transceiver, capable of sending and receiving wireless signals; Otherwise if they only send the trailer it will be considered a transmitter or broadcast point only. The base station will have one or more RF antennas installed to transmit and receive RF signals from other devices.
Why do cellular base stations have backup batteries?
[...] Cellular base stations (BSs) are equipped with backup batteries to obtain the uninterruptible power supply (UPS) and maintain the power supply reliability. While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load.
Why are base stations important in cellular communication?
Base stations are important in the cellular communication as it facilitate seamless communication between mobile devices and the network communication. The demand for efficient data transmission are increased as we are advancing towards new technologies such as 5G and other data intensive applications.
What are the components of a base station?
Power Supply: The power source provides the electrical energy to base station elements. It often features auxiliary power supply mechanisms that guarantee operation in case of lost or interrupted electricity, during blackouts. Baseband Processor: The baseband processor is responsible for the processing of the digital signals.
