METHOD AND SYSTEM OF USING SMART ANTENNAS FOR BACKHAULING
First Claim
1. A wireless communication system for utilizing at least one smart antenna for establishing a backhaul network, the system comprising:
- a plurality of nodes, each node connected to at least one neighbor node, each node comprising;
a smart antenna configured to generate a plurality of directional beams;
a memory configured to store a list of neighbor nodes having connections and beam configuration information to be used in transmission of messages to the neighbor nodes; and
a controller configured to;
update the list stored in the memory by monitoring signals received from the neighbor nodes and determining configurations for transmitting data to the neighbor nodes andselect a particular directional beam for transmitting a particular message to another node using the updated list stored in the memory,at least one of the plurality of nodes being a hybrid node that further comprises a wired backhaul connection to a core network.

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.
