RADIO UNIT FOR WIRELESS COMMUNICATION WITH A BASE BAND UNIT ACCORDING TO A RADIO ACCESS NETWORK PROTOCOL AND A BASE BAND UNIT

The present disclosure relates to a radio unit (RU) for wireless communication with a base band unit (BBU) according to a radio access network (RAN) protocol. The RU is configured to establish a first bidirectional connection with the BBU, the first bidirectional connection being allocated over a first frequency band of the electromagnetic spectrum. The RU is configured to establish a second bidirectional connection with the BBU, the second bidirectional connection being allocated over a second frequency band of the electromagnetic spectrum used for radio access communication. The RU is configured to use the second bidirectional connection for communicating with the BBU i n case one or more channel quality parameters of the first bidirectional connection do not fulfill a threshold for the respective channel quality parameter or in case the first bidirectional connection is interrupted.
