Synchronized wireless mesh network
First Claim
1. A synchronized directional wireless mesh network, comprising:
- a substantially rectangular grid of at least four directional mesh nodes, each node having at least four radio-antenna combinations assigned to communicate on a common channel, each combination including a relay radio connected to an individual directional antenna wherein at least one of said radio-antenna combinations of a node is aimed in a substantially orthogonal direction relative to at least one other radio-antenna combination of said node; and
wherein all radio-antenna combinations, which are on mesh nodes that are aligned diagonally in the rectangular grid and which are operating on the same common channel, are adapted to transmit in unison and to receive in unison.

Abstract
A synchronized wireless mesh network is described where mesh nodes have one or more relay radios and multiple directional antennas aimed in horizontally orthogonal directions. A rectangular grid of such mesh nodes can include at least 4 nodes arranged in a rectangular formation such that diagonally aligned nodes are incapable of communicating directly to each other. Adjacent nodes, on the other hand, can be controlled to transmit and receive to each other in an alternating sequence. Thus, diagonally aligned nodes can be controlled to transmit and receive in unison. Such a network can enable for greater speed and simultaneity of packet propagation and provide for less interference amongst adjacent nodes. Other embodiments are also described where radio transmission and reception at a particular node having multiple radios are synchronized to eliminate co-channel, adjacent channel and cross-channel interference.
