## 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.

## Claims

### Claim 1

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

### Claim 2 (depends on 1)

The system of claim 1, wherein the adjacent sectors do not overlap.

### Claim 3

A data transmission method comprising:
detecting rotation of a set of directional antennas;
identifying, when the detected rotation exceeds a threshold amount, a changed alignment of adjacent sectors of a plurality of sets of directional antennas each having a set of directional antennas rotatably mounted on a common respective axis;
upon identification of the changed alignment, providing revised routing information to the plurality of sets of directional antennas; and
upon identification of the changed alignment, rebroadcasting a data packet between adjacent sets of directional antennas utilizing directional antennas identified by the revised routing information.

### Claim 4 (depends on 3)

The method of claim 3, wherein the adjacent sectors do not overlap.
