In a redundant wireless base station, a first baseband processing unit is coupled to a first radio unit and a second baseband processing unit is coupled to a second radio unit. A link couples the first baseband processing unit and the second baseband processing unit. The link allows at least one of the first baseband processing unit and the second baseband processing unit to one or more of transmit and receive via the first radio unit and the second radio unit. A buffer is associated with the link. The buffer is configured to synchronize one or more of transmission and reception via the first radio unit and the second radio unit.
