Simultaneous transmission on shared channel
First Claim
1. A system, comprising two or more radios collocated with one another, the two or more radios communicating with two far radios over a pair of long range wireless links, the two or more radios being configured to transmit and receive in synchronization with one another on a same channel, wherein 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, further wherein the on-axis response the two or more radios are substantially equal to one another, wherein the on-axis response for a radio occurs along a main axis between the two or more radios and the two far radios, and the off-axis response occurs when interference is experienced based on overlapping signals generated between any of the two or more radios and the two far radios, further wherein any of transmit and receive antenna gains of the two or more radios are selectively adjusted to compensate for disparate signal strengths in their on-axis responses.

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.

13. A method, comprising:
transmitting signals on a same channel by two or more collocated radios by; synchronizing transmit and receive time periods of the two or more collocated radios such that the two or more collocated radios transmit at a same time and receive at a same time as one another; reducing an off-axis response for each of the two or more collocated radios relative to their on-axis response, wherein the on-axis response for a radio occurs along a main axis between the two or more collocated radios and two far radios, and the off-axis response occurs when interference is experienced based on overlapping signals generated between any of the two or more collocated radios and the two far radios; and balancing the on-axis response for each of the two or more collocated radios such that they are substantially equivalent to one another. - View Dependent Claims (14, 15, 16, 20)

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 radios transmit at a same time and receive at a same time as one another on the shared channel; and balancing the on-axis response for each of the two or more radios such that they are substantially equivalent to one another, wherein the on-axis response for a radio occurs along a main axis between the two or more radios and two far radios, and an off-axis response occurs when interference is experienced based on overlapping signals generated between any of the two or more radios and the two far radios. - View Dependent Claims (18, 19)
