Abstract: A method of reducing packet loss resulting from header compression during data transmission comprising of calculating, by a transmitter, the difference between one or more delta fields of each packet among a plurality of packets and a base frame of data wherein for at least a portion of the packets, the base frame is a packet other than a packet immediately preceding the packet for which the difference is calculated, encoding the difference and compressing the plurality of packets using the transmitter; transmitting, using the transmitter, the plurality of compressed packets and an uncompressed full-header packet through a communications channel to a receiver, receiving the plurality of compressed packets and the uncompressed full-header packet by the receiver, and decompressing, by the receiver, the plurality of compressed packets using the difference between the one or more delta fields of each packet among the plurality of compressed packets and the base frame.

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.
