Simultaneity is the relation between two events assumed to be happening at the same time in a given frame of reference. According to Einstein's theory of relativity, simultaneity is not an absolute relation between events; what is simultaneous in one frame of reference will not necessarily be simultaneous in another (see Relativity of simultaneity). For inertial frames moving relative to one another at low speeds compared to the speed of light, this effect is small and can for practical matters be ignored, allowing simultaneity to be treated as an absolute relation.

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.

A directional and interleaved wireless mesh network is described where mesh nodes have directional antennas facing in horizontally orthogonal directions. The antennas can be focused to have a beam width of less than ninety degrees in order to achieve greater strength of signal and radiation. Each mesh node can have two radios that communicate on separate channels, such that packets propagated through the mesh network can utilize either channel in order to hop from one node to the next. Each radio can be connected to four orthogonally directed antennas in order to enable communication with adjacent nodes. Alternatively, a separate independent radio can be connected to each antenna in order to achieve greater simultaneity of transmission and reception to the node. For example, two such radio-antenna combinations can be facing in each of the four orthogonal directions, each of the two combinations operating on a different RF channel.
