Problem
Current wireless communication systems face challenges in densification due to difficulties in finding suitable locations for radios, managing backhaul and fronthaul, and adhering to government regulations regarding radio and antenna placement.
Innovation Solution
The implementation of a daisy-chain network and power cable system using small, multi-user multi-antenna system (MU-MAS) radioheads, which are integrated into the cabling infrastructure, allowing for flexible and aesthetically pleasing deployments without the need for traditional radio and antenna installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional radio and antenna installations are used, then wireless coverage can be provided, but deployment becomes complex and requires government permits
Solution Approach 1:
The patent combines the radio and antenna into a single integrated radiohead unit that is directly coupled to the cable infrastructure. This merging eliminates the need for separate radio and antenna installations, simplifying deployment while maintaining reliable wireless coverage through the integrated design.
Solution Approach 2:
The radiohead is designed to perform multiple functions: it receives cable signals, generates wireless signals, and provides wireless coverage. This multi-functionality allows a single device to replace traditional separate installations, reducing deployment complexity while maintaining coverage reliability.
2Reliability
If traditional radio and antenna installations are used, then wireless coverage can be provided, but aesthetic appearance deteriorates
Solution Approach 1:
By merging the radio and antenna into a single compact radiohead that is integrated into the cable infrastructure, the patent eliminates the need for visible separate antenna installations. This maintains aesthetic appearance while providing reliable wireless coverage through the integrated design.
3Reliability
If more radios are deployed to improve coverage, then wireless coverage is enhanced, but difficulty in finding suitable locations increases
Solution Approach 1:
The radiohead's ability to function with existing cable infrastructure provides universal deployment capability. It can be installed in diverse locations including utility poles, buildings, and other structures with cable access, significantly increasing location flexibility while enhancing wireless coverage.
Solution Approach 2:
The patent transitions from traditional ground-based radio installations to utilizing the vertical cable infrastructure dimension. This allows deployment in previously unsuitable locations by leveraging the three-dimensional cable network, increasing adaptability to various environments.
4Ease of manufacture
If radioheads are integrated into cabling infrastructure, then deployment is simplified, but device complexity increases
Solution Approach 1:
The patent simplifies deployment by merging the radio and antenna functions into a single radiohead that interfaces directly with cable infrastructure. While the integrated device is more complex internally, this consolidation eliminates the need for multiple separate installations and complex interconnections, overall simplifying the deployment process.
