Abstract

The present disclosure discloses a system including a controller and multiple radio heads connected to the controller through communication cables. The controller transmits a synchronization signal to each of the radio heads to synchronize the local clocks in the radio heads to a master clock in the controller. The controller also transmits packets to the radio heads using the communication cables. Each of the radio heads includes a digital-to-analog converter (DAC), an antenna coupled to an output of the DAC, and a deframer coupled to an input of the DAC. For a radio head, upon detecting that a received packet from the controller includes an error, the deframer alters the received packet to maintain the synchronization between the controller and the radio head and transmits the altered packet to the DAC.
