Abstract

Simultaneous transmission on a shared channel by a plurality of collocated radios is provided herein. The two or more radios are collocated with one another and are communicating with two far radios over a pair of long range wireless links. The two or more radios are configured to transmit and receive in synchronization with one another on a same channel. An off-axis response for each of the two or more radios is reduced compared to their on-axis response for improved signal to noise ratio, and the on-axis response the two or more radios are substantially equal to one another.

Claims

13-1. The method according to claim 13, further comprising receiving GPS information in order to synchronize the transmit and receive time periods.

17. A method of communication synchronization between two or more radios, the two or more radios having angular separation or physical characteristics that optimize their on-axis responses, the method comprising:

selecting a shared channel for the two or more radios;

synchronizing transmit and receive time periods of the two or more radios such that the two or more collocated radios transmit at the same time and receive at the same time as one another on the shared channel; and

balancing an on-axis response for each of the two or more radios such that they are substantially equivalent to one another.

18. The method according to claim 17, wherein the physical characteristics comprise radio shrouds with side lobe rejection.

19. The method according to claim 17, wherein synchronizing transmit and receive time periods comprises:

receiving at one of the two or more radios, GPS information; and

providing the GPS information to the other of the two or more radios over a wired link or a network connection, wherein the GPS information is used to synchronize the two or more radios.
