Packet-Specific Beam-Forming Network for Wireless Mesh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in wireless mesh networks, packets requiring low latency often suffer from delays due to congestion caused by packets that can tolerate higher latency, sharing the same transmission paths, leading to inefficient data transport.
Innovation Solution
The system employs multiple beam directions for packet transmission based on packet-related information, allowing for dynamic switching between different paths to prioritize low-latency packets by using multi-beam subsystems in communication nodes to switch beam directions on a packet-by-packet basis, ensuring efficient and timely data transport.

Engineering Contradiction Analysis
1Productivity
If multiple packets share the same transmission path, then the transmission path utilization is improved, but the latency of low-latency packets deteriorates due to congestion
Solution Approach 1:
The patent segments the transmission path into multiple beam directions (first beam direction and second beam direction) to create separate transmission channels. Low-latency packets are routed through a dedicated beam direction while other packets use alternative beam directions, effectively dividing the transmission resource to prevent congestion and ensure timely delivery of time-sensitive packets.
Solution Approach 2:
The patent introduces a spatial dimension by using multiple beam directions for packet transmission. Instead of sharing a single transmission path, packets are transmitted through different spatial channels (beam directions), allowing simultaneous transmission without interference and eliminating congestion-related latency for critical packets.
2Loss of time
If beam direction switching is implemented on a packet-by-packet basis, then the latency for critical packets is reduced, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple beam directions and establishing routing rules before packet transmission. The system determines in advance which beam direction to use for each packet based on packet characteristics, eliminating the need for complex real-time switching decisions and reducing control complexity while maintaining low latency.
Solution Approach 2:
The patent changes the beam direction parameter based on packet characteristics and routing requirements. By dynamically adjusting this single parameter (beam direction) rather than reconfiguring the entire transmission system, the patent achieves low-latency packet transmission while minimizing device complexity.

AI summary
System and methods for wirelessly transporting data from a first communication node to a second communication node using different combinations of beams and on a packet-by-packet basis. Packets associated with a certain Quality of Service (QoS) and/or latency requirements are transported between the first and the second nodes using a first transmission path, while packets associated with a different QoS/latency requirements, are transported between the first and the second nodes using another transmission path, in which in order to switch from the first path to the second path, the system adjusts appropriate beam directions in real-time, and so as to result in fast-switching beam configurations that dynamically change in accordance to packet movement in the network. Latency-critical packets are directed to the faster path, while other packets are directed to the slower path, so as to prevent network congestion and optimize overall network performance.
