AI Technical Summary

Problems solved by technology

[0004] However, the disadvantages of wired connections in establishing a backhaul network are that they are expensive, time consuming, and inflexible to network variations or modifications
Mesh networks in particular must require nodes to be connected to each other, and when a new node joins the mesh network, establishing a new connection to that new node for the backhaul is a significant load (in terms of cost and time)

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.

Description

technical field [0001] The present invention relates to a wireless communication, and in particular, the present invention relates to a method and system for establishing a backhaul network using smart antennas. Background technique [0002] One of the most important issues in wireless communication systems is to increase system capacity by reducing interference. Array antennas (also called smart antennas) have been developed to improve capacity and reduce interference. Smart antennas use multiple antenna elements to create directional beams that only send signals in a specific direction. With smart antennas, wireless communication systems can increase capacity and reduce interference because signals are sent to a narrow area within the coverage area. Overall system capacity is increased because the transmitter can increase the transmission power level directed at the beam without causing undue interference to other transmitters or receivers, such as wireless transmit / recei...
