Radio Frequency Remote Unit (RRU) Key Component for Wireless Signal Transmission

Currect and voltage requirements must be met to operate the RRU and thus, the power supply is critical to the RRU's stable operation. RRUs with different capabilities, for instance the numner of carriers they support and their power - output levels, may have different power - consumption levels. A protection against over - voltage, under - voltage, and short - circuit must also be implemented for any system to have a proper power - supply configuration. For the sake of uninterrupted operation in case of a power - supply failure, redundant power - supply systems are implemented in some cases which helps maintain the functionality of the communication network.
