Access Point Backbone Network Configuration Using TV White Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area networks (WLANs) face limitations in bandwidth and transmission power when using the IEEE 802.11af standard for wide-area coverage and the IEEE 802.11ah standard for continuous operation, as they require periodic verification of TV white space information and lack secure wide bandwidth.
Innovation Solution
Configuring an integrated network by employing a first available band associated with TV white space and a band of 1 GHz or less for backbone network setup between access point apparatuses, and using a second available band for connections between access points and stations, leveraging the wide bandwidth and high transmission output of TV white space and the always-available nature of the 1 GHz band.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If IEEE 802.11af standard is used for wide-area coverage, then transmission output and bandwidth are improved, but periodic verification of TV white space information is required
Solution Approach 1:
The patent combines IEEE 802.11af and IEEE 802.11ah standards into an integrated network where APs use TV white space bands for backbone communication and 1 GHz or less bands for station connections, eliminating the need for periodic verification while maintaining wide-area coverage capability
Solution Approach 2:
The access point apparatus is designed to operate across multiple frequency bands (TV white space and 1 GHz or less) simultaneously, making the system universally applicable for both wide-area backbone communication and continuous local connections without requiring band-specific verification procedures
2Reliability
If IEEE 802.11ah standard is used for continuous operation, then availability is improved, but bandwidth and transmission power are limited
Solution Approach 1:
The patent segments the wireless network into two functional parts: backbone network using TV white space bands for high-power transmission, and local station connections using 1 GHz or less bands for continuous operation, allowing each segment to operate optimally without compromising the other
3Area of stationary object
If integrated network configuration is implemented, then wide area coverage and continuous connectivity are achieved, but network complexity increases
Solution Approach 1:
The access point apparatus autonomously verifies available bands and configures backbone networks without external intervention, with the verification unit automatically selecting appropriate frequency bands and the configuration unit establishing connections based on predetermined criteria, thereby reducing manual configuration complexity
