Wireless Direct Transmission for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, data traffic between client devices often experiences latency and jitter due to the need for packets to transit through wired portions of the network, which can make wireless options less reliable and less efficient, especially in environments requiring deterministic communication.
Innovation Solution
Enabling multi-radio Access Points (APs) to communicate directly with each other and with client devices in an ad hoc mode for certain types of traffic, allowing for the use of either wired or wireless paths, or both for redundancy, to bypass the fabric network and controller, thereby optimizing resource usage and reducing latency and jitter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data traffic transits through wired portions of the network via APs and controller, then network reliability is improved, but latency and jitter increase
Solution Approach 1:
The patent introduces wireless direct transmission as an intermediary pathway that allows client devices to communicate directly without routing through wired network infrastructure. This mediator pathway bypasses the traditional wired route (AP→controller→AP) and enables peer-to-peer wireless communication, thereby reducing latency and jitter while maintaining connection reliability through multiple available paths.
Solution Approach 2:
The system dynamically selects between wired and wireless transmission pathways based on real-time network conditions and traffic requirements. The network can adaptively route traffic through the most appropriate path (wired for reliability-critical traffic, wireless direct for latency-sensitive traffic), making the network flexible and responsive to changing conditions rather than following a fixed routing structure.
2Productivity
If multi-radio APs communicate directly via wireless paths, then resource usage is optimized, but transmission reliability may decrease
Solution Approach 1:
The patent changes the transmission medium parameter from wired to wireless direct communication between APs and client devices. By altering the physical transmission path parameter, the system achieves better resource utilization (reducing wired network load and controller processing) while accepting and managing the trade-off in reliability through dynamic path selection and redundancy mechanisms.
Solution Approach 2:
The network communication path is segmented into multiple independent routes: wired paths through traditional infrastructure and wireless direct paths between devices. This segmentation allows different types of traffic to use different pathways, optimizing resource usage for each traffic type while maintaining overall system reliability through path diversity.
3Manufacturing precision
If wireless direct transmission is used for critical traffic, then Service Level Agreement requirements are met, but network complexity increases
Solution Approach 1:
The system performs preliminary assessment of traffic characteristics and network conditions to determine which traffic flows require wireless direct transmission. By pre-identifying critical traffic that needs to meet SLA requirements and proactively routing it through appropriate pathways, the system ensures compliance without requiring complex real-time decision-making for every packet, thereby managing network complexity.

AI summary
Leveraging wireless direct transmissions may be provided. It may be determined that data traffic flowing on a first pathway between a first client device and a second client device is not meeting a predetermined service level. The first pathway may be partially wired and partially wireless. A second pathway that will meet the predetermined service level may be determined. The second pathway may be wireless. The data traffic may be caused to flow on the second pathway.
