Abstract: Provided is a system for data transmission in a wireless network including a plurality of sets of directional antennas with each set of directional antennas rotatably mounted on a common axis and each antenna of each set of directional antennas focused in a different sector emanating from a respective common axis, and a memory includes routing information identifying aligned sectors of adjacent sets of directional antennas. Detection of rotation of a set of directional antennas beyond a threshold amount identifies a changed alignment of adjacent sectors. Upon identification of the changed alignment of the adjacent sectors, revised routing information is provided to the plurality of sets of directional antennas. Upon identification of the changed alignment of the adjacent sectors, a data packet is rebroadcast between adjacent sets of directional antennas utilizing directional antennas identified by the revised routing information.

Abstract: Disclosed is a data transmission system having a multi-node wireless network in a geographic area within which a plurality of nodes are positioned, having a plurality of directional antennas fixed to respective nodes of the plurality of nodes, with each node including at least two directional antennas to transmit and receive in respective sectors emanating from each respective node. When yaw of a node exceeds a threshold amount, revised routing information is provided to identify preferred directional antennas for use in future link transmissions.
