Abstract
A method and system for utilizing smart antenna in transmission of messages between nodes are disclosed. A wireless communication system includes a plurality of nodes, and each node is capable of being connected to each other node. At least a portion of the nodes are provided with a smart antenna configured to generate a plurality of directional beams. Each node maintains a list of other nodes and beam configuration information to be used in transmission of messages to other nodes. When a source node is required to transmit to a target node, the source node retrieves the beam configuration information and transmits with a directional beam directed to the target node.
Claims20
A wireless communication node comprising:
- an antenna array;
- a controller, operatively coupled to the antenna array, configured to establish wireless cellular connections with a plurality of nodes;
- wherein a first of the plurality of nodes is wired connected to a core network and at least a second of the plurality of nodes is not wired connected to the core network;
- wherein the controller is further configured to exchange backhaul data over the wireless cellular connection with the first node and not the second node;
- wherein the controller is further configured to receive wireless beamformed backhaul data from the first node and transmit wireless beamformed data to the second node;
- and
- wherein the controller is further configured to change a beam to the second node in response to measured channel conditions.
A method comprising:
- establishing, by a wireless communication node, wireless cellular connections with a plurality of nodes;
- wherein a first of the plurality of nodes is wired connected to a core network and at least a second of the plurality of nodes is not wired connected to the core network;
- exchanging, by the wireless communication node, backhaul data over the wireless cellular connection with the first node and not the second node;
- wherein backhaul data received from the first node and data transmitted to the second node are beamformed;
- and
- wherein a beam formed to the second node is changed in response to measured channel conditions.
A fixed location wireless communication node comprising:
- an antenna array;
- a wireline connection operatively coupled to at least a core network;
- a controller, operatively coupled to the antenna array and the wireline connection, configured to exchange backhaul data over the wireline connection;
- wherein the controller is further configured to establish wireless cellular connections with a plurality of nodes;
- wherein the controller is further configured to exchange backhaul data with a first of the plurality of nodes over its wireless cellular connection;
- wherein the controller is further configured to transmit wireless beamformed backhaul data to the first node using the antenna array;
- wherein the controller is further configure to exchange data not including backhaul data with a second of the plurality of nodes over its wireless cellular connection;
- wherein the controller is further configured to transmit wireless beamformed data to the second node using the antenna array;
- and
- wherein the controller is further configured to adjust beams to the first and second nodes in response to measured channel conditions.
A method comprising:
- exchanging, by a fixed location wireless communication node, backhaul data over a wireline connection;
- wherein the wireline connection is coupled to at least a core network;
- establishing, by the fixed location wireless communication node, wireless cellular connections with a plurality of nodes;
- exchanging, by the fixed location wireless communication node, backhaul data with a first of the plurality of nodes over its wireless cellular connection;
- wherein the backhaul data transmitted to the first node is beamformed;
- exchanging, by the fixed location wireless communication node, data not including backhaul data with a second of the plurality of nodes over its wireless cellular connection;
- wherein data transmitted to the second node is beamformed;
- and
- adjusting, by the fixed location wireless communication node, beams to the first and second nodes in response to measured channel conditions.
