White Space Utilization via Proxy Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices lacking the capability to determine their geographic location and access regulatory databases struggle to obtain authorization to use radio white space frequencies, limiting their ability to communicate efficiently over underutilized TV white spaces.
Innovation Solution
A device can leverage another device with Internet access and location-determination capabilities to obtain authorization for radio white space frequencies, acting as a proxy to establish Wi-Fi communication and convey these frequencies to other devices, ensuring compliance with constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a device uses TV white space frequencies for communication, then spectrum utilization efficiency is improved, but the device complexity increases due to requirements for location determination and database access
Solution Approach 1:
The patent introduces a Wi-Fi access point as an intermediary device that performs the complex tasks of location determination and regulatory database access on behalf of the simpler client device. The access point has the capability to determine its geographic location and query the database to obtain authorized white space frequencies, while the client device only needs basic Wi-Fi connectivity to communicate with the access point and utilize the authorized frequencies for data transmission.
2Measurement precision
If a device obtains authorization for radio white space frequencies through direct database access, then authorization accuracy is improved, but the ease of operation deteriorates due to complex requirements for location determination and Internet access
Solution Approach 1:
The Wi-Fi access point serves as an intermediary that handles the complex authorization process. It determines its own geographic location, queries the regulatory database to obtain authorized white space frequencies, and provides this authorization information to client devices. This eliminates the need for client devices to perform location determination or access the database directly, significantly simplifying operation while maintaining authorization accuracy.
Solution Approach 2:
The access point performs the complex tasks of location determination and database querying autonomously on its own, without requiring client devices to have these capabilities. The access point serves itself by obtaining authorization information and then makes this information available to client devices, allowing them to use white space frequencies without needing to understand or perform the complex authorization process themselves.

AI summary
The concepts relate to broadcasting white space utilization. One example can function as a client relative to a wireless access point that is configured to obtain authorization to utilize a radio white space frequency according to a set of constraints. The example can function as a Wi-Fi direct group owner to establish a Wi-Fi connection with a device that is not the wireless access point. This example can also transmit data over the radio white space frequency to the device in compliance with the set of constraints.
