Radio White Space Authorization via Master Device Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without the capability to determine their geographic location or access regulatory databases cannot utilize radio white space frequencies, limiting their ability to communicate efficiently due to lack of access to underutilized TV white spaces and other radio white spaces.
Innovation Solution
These devices can leverage another device with the necessary capabilities to obtain authorization for radio white space frequency usage by interacting with it to determine their location and access regulatory databases, allowing them to use TV white spaces or other radio white spaces under specific constraints, thereby bypassing the need for direct Internet access and location determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices directly access regulatory databases to obtain frequency authorization, then frequency usage compliance is ensured, but device complexity and operational requirements increase
Solution Approach 1:
The patent introduces a master device as an intermediary that performs database queries and location determination on behalf of slave devices. The master device obtains frequency authorization and shares it with slave devices, eliminating the need for each device to independently access databases or determine precise location, thus reducing individual device complexity while maintaining compliance through centralized mediation
2Adaptability or versatility
If devices determine precise geographic location to access TV white spaces, then frequency authorization is obtained, but operational complexity and resource requirements increase
Solution Approach 1:
The master device performs multiple functions including location determination, database querying, frequency authorization management, and coordination of slave devices. By consolidating these diverse functions in a single multi-functional device rather than requiring each device to perform them independently, the system enables spectrum access while simplifying operational requirements for individual devices
3Productivity
If all devices have independent database access capability, then frequency authorization is readily obtained, but system resource consumption and operational complexity increase
Solution Approach 1:
The patent merges the database access functionality of multiple slave devices into a single master device. Instead of each device independently consuming resources to query databases, the master device performs a single query and shares the results with all slave devices, thereby maintaining rapid frequency authorization while significantly reducing overall system resource consumption and energy usage

AI summary
The concepts relate to broadcasting white space utilization. One example can interact with a wireless device (106, 404, 704) that is configured to obtain authorization to use a set of radio white space frequencies in accordance with one or more constraints (902). The example can obtain an individual radio white space frequency and associated individual constraints. This example can also utilize the individual radio white space frequency for network access independent from the wireless device (106, 404, 704) that is configured to obtain the authorization.
