Wireless Access Point Network for High-Bandwidth Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in maintaining high-bandwidth video transmission throughout a home or building due to signal degradation from obstacles, bandwidth reduction with repeaters, and quality compromise from data compression, making them unreliable for high-bandwidth applications like video streaming.
Innovation Solution
A self-configuring, adaptive wireless network utilizing cellular techniques with access points operating on different frequency channels to extend transmission range without degrading bandwidth, allowing for multiple simultaneous video streams at high data rates by reusing channels beyond interference ranges and using different frequency bands for repeaters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If wireless repeaters are used to extend coverage throughout the building, then the transmission range is extended, but the bandwidth is reduced for each repeater installed
Solution Approach 1:
The patent transitions from two-dimensional planar coverage to three-dimensional spatial coverage by utilizing vertical stacking of access points on different floors. This dimensional expansion allows the network to cover the entire building volume without requiring additional repeaters that would consume bandwidth, as each floor's access point serves its local area independently while contributing to overall building coverage.
2Area of stationary object
If the number of access points is increased to provide full coverage, then the coverage area is improved, but cable wires must be routed through the interior of the structure
Solution Approach 1:
The patent extracts the physical connection requirement by removing cable wires from the system entirely. Each access point operates independently using wireless communication to relay data, eliminating the need for interior cable routing while maintaining full building coverage. This extraction of the wired connection constraint allows flexible deployment without structural modification.
3Productivity
If data compression is used to transmit video, then bandwidth requirements are reduced, but video quality is compromised
Solution Approach 1:
The patent segments the video transmission path into multiple wireless hops between access points, where each segment operates at full bandwidth capacity. By dividing the transmission journey into discrete segments that each maintain high data rates, the system delivers uncompressed or minimally compressed video quality while distributing the transmission load across multiple wireless links.
4Ease of operation
If wireless networks are used for high-bandwidth video transmission, then installation ease is improved, but reliability is degraded due to signal degradation from obstacles
Solution Approach 1:
The patent introduces access points as intermediary devices that actively relay video data between the source and destination. These intermediaries receive, regenerate, and forward video signals, preventing signal degradation that would occur over long direct wireless paths. Each access point acts as a local repeater that maintains signal integrity while enabling extended coverage throughout the building.
Data Source
AI summary
A method of operation for wireless transmission of data to one or more destination devices across a network that includes a plurality of access points disposed about a building, each access point having a first transmission range of maximum bandwidth and a second transmission range of signal interference, the access points being arranged in a topology wherein each access point is spaced-apart from a nearest neighboring access point by a first distance less than the first transmission range. The data is transmitted by a first access point; then it is repeated by a series of additional access points that extends across the topology. Re-transmission of the data occurs in a manner wherein any pair of access points transmitting on the same channel is separated by a distance greater than the second transmission range.
