METHOD FOR RRU BYPASS IN WIRELESS COMMUNICATION NETWORK AND RRU DEVICE

摘要

The invention discloses a method for RRU bypass in wireless communication network, at least two of the RRUs being cascaded, comprising: monitoring a signal indicating at least one of cascaded RRU is in failure or to be updated; and switching the at least one of cascaded RRU into a bypass mode by connecting a first optical module to a second optical module via a bypass protection unit. A new RRU device with cascading protection is also provided. This enhances the reliability and resilience of the RRU device and the RRU cascading network topology.
