Solution Overview
Problem
In areas with limited connectivity to broadband Internet infrastructure, existing technologies face challenges in efficiently delivering high-bandwidth digital content to users, such as video and music, due to the lack of reliable access points and high-latency content delivery methods.
Innovation Solution
A wireless mesh network (WMN) architecture is implemented, utilizing multi-radio, multi-channel (MRMC) mesh network devices with phased array patch antennas and omnidirectional antennas to create a self-contained network that distributes content through peer-to-peer connections, reducing reliance on traditional broadband infrastructure and enabling efficient content delivery to client devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional broadband infrastructure is used for content delivery, then high-bandwidth digital content can be delivered to users, but the system fails in areas with limited connectivity to broadband Internet infrastructure
Solution Approach 1:
The network is segmented into multiple mesh network devices that form a distributed peer-to-peer content delivery system. Each device acts as an independent node that can store and forward content, eliminating reliance on centralized broadband infrastructure. This segmentation enables the system to operate reliably in areas with limited broadband connectivity by creating local content delivery paths through multiple devices.
2Productivity
If multiple radios operate concurrently in an MRMC device, then content delivery bandwidth is improved, but radio frequency interference between antennas increases
Solution Approach 1:
The patent extracts and isolates each antenna into a separate isolation chamber within the MRMC device housing. This physical separation removes the harmful radio frequency interference between concurrently operating antennas by preventing electromagnetic coupling. Each chamber acts as an independent enclosure that contains the RF signals from its respective antenna, allowing multiple radios to operate at full power without mutual interference, thereby maintaining high content delivery bandwidth.
3Volume of moving object
If antennas are placed close together in a compact MRMC device, then device size is reduced, but electromagnetic isolation between antennas deteriorates
Solution Approach 1:
The patent implements a nested structure where multiple isolation chambers are integrated within the compact MRMC device housing. Each antenna is enclosed in its own chamber, and these chambers are nested within the overall device structure. This nested arrangement maintains close proximity of multiple antennas for compact device size while the individual chamber walls provide electromagnetic isolation, preventing interference between adjacent antennas.
4Object-generated harmful factors
If isolation chambers are added to separate antennas in an MRMC device, then radio frequency interference is reduced, but device complexity increases
Solution Approach 1:
The patent merges the isolation chamber structure with the MRMC device housing itself, rather than adding separate isolation components. The housing is designed with integrated chambers that serve both as structural enclosure and as electromagnetic isolation barriers. This merging approach reduces device complexity by combining multiple functions (mechanical support and RF isolation) into a single integrated structure, eliminating the need for additional isolation components.
