Abstract: A method of seamless antenna handover comprising transmitting at least one of a handover trigger packet and a handover synchronization packet (HSP) by a transmitter to a first and a second repeating relay, the first repeating relay configured to transmit a data signal to a first modem at a remote receiver and the second repeating relay configured to transmit the data signal to a second modem at the remote receiver, receiving, by the first and second modems at the remote receiver, the data signal and the at least one of the handover trigger packet and the HSP from the first and second repeating relays, respectively, and activating one of the first and second modems and deactivating the other of the first and second modems in response to receiving the at least one of the handover trigger packet and the HSP.
