A combined fixed directional and mobile omnidirectional interleaved wireless mesh network is described where the fixed mesh nodes have directional antennas facing in horizontally orthogonal directions. The antennas can be focused to have a horizontal beam width of less than ninety degrees in order to achieve greater strength of signal and radiation. Each directional node can have multiple radios that communicate on separate channels, such that packets propagated through the mesh network can utilize any channel to enter or leave a particular node. The combined network also includes mobile nodes that utilize multiple radios, each connected to an omnidirectional antenna and operating on a different channel. The mobile nodes can maintain constant communication with the directional nodes as they move between various quadrants covered by the directional nodes. The mobile nodes can also maintain connections to each other even during the loss of communication with the fixed directional nodes.
