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.
Claims23
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, the on-axis response for a radio occurring along a main axis between the two or more radios and the two far radios, and an off-axis response occurring when interference is experienced based on overlapping signals generated between any of the two or more radios and the two far radios, the on-axis response of each of the two or more radios being approximately equal to one another;
- a cloud controller that monitors interference by determining any of the two or more radios that are not operating in synchronization with one another and selectively controls the two or more radios over a network;
- and
- a spectral scanner that is configured to sense asynchronous broadcast periods.
A method, comprising:
- transmitting signals on a same channel by two or more collocated radios, the two or more collocated radios communicating with two far radios over a pair of long range wireless links, by:
- monitoring interference by determining any of the two or more collocated radios that are not operating in synchronization with one another;
- selectively controlling the two or more collocated radios over a network;
- sensing asynchronous broadcast periods of the two or more collocated radios;
- 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 the 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;
- and
- balancing the on-axis response for each of the two or more collocated radios such that they are approximately equivalent to one another, the on-axis response for a radio occurring along a main axis between the two or more collocated radios and the two far radios.
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 two or more radios configured to communicate with two far radios over a pair of long range wireless links, the method comprising:
- selecting a shared channel for the two or more radios;
- monitoring interference by determining any of the two or more radios that are not operating in synchronization with one another;
- selectively controlling the two or more radios over a network;
- sensing asynchronous broadcast periods of 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 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 approximately equivalent 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.
