Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless access technologies face limitations in maximum bandwidth due to interference and congestion in unlicensed radio frequencies, particularly in Wi-Fi networks, which affect mobile accessing terminals.
Innovation Solution
A distributed access point multilink device (AP-MLD) system that utilizes a control apparatus with upper MAC functionality and a point-to-multipoint radio transceiver to establish contemporaneous multipoint links between 52.6 GHz and 1THz, connecting to multiple spatially separated peripheral apparatuses with lower MAC functionality, enabling high bandwidth and low interference through beamforming and dynamic reconfiguration of radio links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple simultaneous radio links are established to increase maximum bandwidth, then bandwidth is improved, but interference and congestion in unlicensed radio frequencies worsen
Solution Approach 1:
The system segments the radio link into multiple spatial paths using beamforming technology. Multiple beams are directed toward different spatial locations to reach the same terminal, effectively dividing the communication path into parallel segments that utilize different spatial resources, thereby increasing bandwidth while managing interference through spatial separation
Solution Approach 2:
The patent transitions from traditional single-dimension radio link establishment to multi-dimensional spatial communication by implementing point-to-multipoint beamforming. This adds the spatial dimension to radio link management, allowing simultaneous establishment of multiple links in different spatial directions, thus increasing bandwidth capacity while distributing interference across different spatial domains
2Productivity
If unlicensed radio frequencies are used to increase bandwidth availability, then bandwidth is improved, but interference and congestion worsen
Solution Approach 1:
The system applies local quality by directing targeted beams toward specific spatial locations rather than broadcasting omnidirectionally. Each beam is optimized for its specific spatial path, allowing efficient utilization of unlicensed spectrum in each local spatial region while minimizing interference with other users of the same frequency band
3Productivity
If point-to-multipoint beamforming is implemented at radio frequencies between 52.6 GHz and 1 THz, then bandwidth and data rate are improved, but system complexity increases
Solution Approach 1:
The patent implements a distributed access point architecture where multiple peripheral apparatuses can each function as beamforming nodes. This universal design allows any peripheral device to contribute to the point-to-multipoint beamforming capability, distributing the computational and hardware complexity across multiple devices rather than concentrating it in a single access point
