Beam Forming Antenna Configuration via Signal Distortion Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring beam forming antennas in communication networks, particularly at high frequencies like 60 GHz, face challenges such as high resource costs, bandwidth requirements, and inefficiencies due to the need for precise antenna aiming and orthogonal signal encoding, which are not well-suited to network topology and can lead to interference with adjacent networks.
Innovation Solution
A method that configures a beam forming antenna by emitting a signal through multiple communication links, aggregating physical magnitudes representing distortion across these links to adjust antenna parameters, allowing for efficient configuration without high bandwidth or resource-intensive operations, and ensuring directional emissions to prevent interference with adjacent networks.

Engineering Contradiction Analysis
1Power
If beam forming antenna is used to transmit signal at high frequency (60 GHz), then signal transmission capability is improved, but antenna gain requirement increases leading to more complex antenna configuration
Solution Approach 1:
The antenna system automatically configures itself by using the received signal from the remote node to determine optimal beam directions and weighting coefficients, eliminating the need for manual or complex external configuration processes
Solution Approach 2:
The system uses feedback from the remote node's received signal strength information to iteratively adjust and optimize the beam forming parameters, enabling adaptive configuration based on actual transmission conditions
2Productivity
If precise antenna aiming is performed to achieve high gain, then transmission efficiency is improved, but time consumption increases which is not appropriate for high data rate applications
Solution Approach 1:
The system performs preliminary beam direction estimation using the known geometry of the network and initial signal transmission, then quickly refines the configuration using feedback from the first received signal, avoiding time-consuming exhaustive searching
Solution Approach 2:
The system changes beam direction parameters and weighting coefficients based on received signal strength feedback, enabling rapid adaptation to optimal configuration without extensive manual aiming procedures
3Reliability
If orthogonal signals with long codes are used for network communication, then signal differentiation capability is improved, but resource cost and bandwidth requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for beam configuration (received signal strength on each antenna element) from the transmitted signal, eliminating the need for complex orthogonal encoding schemes and long codes while maintaining communication reliability
Solution Approach 2:
The system replaces the mechanical/applicative approach of orthogonal signal encoding with a physical field-based approach, using the natural propagation characteristics of electromagnetic waves and simple signal strength measurements to achieve signal differentiation and beam optimization
4Length of stationary object
If beam forming antenna with narrow beam is used to achieve high gain, then transmission distance capability is improved, but interference with adjacent networks increases
Solution Approach 1:
The system applies different weighting coefficients to different antenna elements to create localized beam patterns that concentrate energy in the direction of the remote node while minimizing radiation in other directions, thus reducing interference with adjacent networks

AI summary
A method of configuring a beam forming antenna in a communication network that comprises a first node where the beam forming antenna is located, second nodes and at least one destination node, communication links being established between said first node and said at least one destination node through at least some of said second nodes.
