Wireless mesh network node
View Patent ↗Method and apparatus for providing a wireless mesh network and network node are described. More particularly, a network having network node neighborhoods is described. A node comprises a multi-sectored antenna and a transceiver controller. Nodes are configured for installation without antenna pointing and without pre-coordination with the network. Software architecture for the node is also described.
1. A network node within a mesh network, the network node comprising:
a transceiver for sending and receiving signals within the mesh network;
a plurality of antenna arrays, wherein each of the plurality of antenna arrays comprises a plurality of sectors;
a first switch, coupled to the plurality of antenna arrays, for selecting from the plurality of antenna arrays at least one sector corresponding to a location of a given network node of the mesh network, wherein the location is known by the network node; and
a second switch, coupled to the first switch, for selecting at least one of the plurality of antenna arrays that comprises the at least one sector.
2. The network node of claim 1 wherein the plurality of sectors comprises at least one of a trough, modified trough or corner reflector.
3. The network node of claim 2 wherein the plurality of antenna arrays comprise two antenna arrays, each antenna array comprising four sectors.
4. The network node of claim 3 wherein the first switch is coupled to each of the four sectors within each of the two antenna arrays.
5. The network node of claim 4 wherein the second switch is coupled to the first switch for selecting one of the two antenna arrays.
6. The network node of claim 4 further comprising:
a switch driver for providing a drive signal to the first switch, wherein the first switch is responsive to the drive signal and selects the at least one sector in response to the drive signal.
7. The network node of claim 6 further comprising a transceiver controller for providing a sector switch control signal to the switch driver, wherein the switch driver produces the drive signal in response to receiving the sector switch control signal.
8. The network node of claim 7 wherein the transceiver controller is configured for real-time execution.
9. A network node within a mesh network, the network node comprising:
a transceiver for sending and receiving signals within a mesh network;
an antenna comprising a plurality of antenna arrays, where each of the plurality of antenna arrays comprises a plurality of sectors; and
a switching means for (i) selecting an antenna array from the plurality of antenna arrays; (ii) selecting, a within the selected antenna array, at least one sector corresponding to a location of a given network node of the mesh network, wherein the location is known by the network node; and (iii) coupling the transceiver to the selected at least one sector.
10. The network node of claim 9 wherein the plurality of sectors comprises at least one of a trough, modified trough or corner reflector.
11. The network node of claim 10 wherein the plurality of antenna arrays comprise two antenna arrays, each antenna array comprising four sectors.
12. The network node of claim 11 wherein the switching means includes a first switch, and wherein the first switch is coupled to each of the four sectors within each of the two antenna arrays.
13. The network node of claim 12 wherein the switching means includes a second switch, and wherein the second switch is coupled to the first switch for selecting one of the two antenna arrays.
14. The network node of claim 12 further comprising:
a switch driver for providing a drive signal to the first switch, wherein the first switch is responsive to the drive signal and selects the at least one sector in response to the drive signal.
15. The network node of claim 14 further comprising a transceiver controller for providing a sector switch control signal to the switch driver, wherein the switch driver produces the drive signal in response to receiving the sector switch control signal.
16. The network node of claim 15 wherein the transceiver controller is configured for real-time execution.
17. A method of selecting at least one sector within an antenna array of a network node in a mesh network, the method comprising:
selecting an antenna array from a plurality of antenna arrays;
selecting, from a plurality of sectors within the selected antenna array, at least one sector corresponding to a location of a given network node of the mesh network, wherein the location is known by the network node;
connecting the selected at least one sector to a transceiver; and
communicating to another transceiver within the mesh network via the selected at least one sector.
