Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing crowding in the 2.4 GHz and 5 GHz frequency bands for Wi-Fi networks, coupled with restrictions on the 6 GHz frequency band due to incumbent wireless infrastructures, necessitates accurate location information for network devices to operate at higher power levels without interference.
Innovation Solution
A method and system for determining a change in location of network devices using location integrity parameters, enabling them to send accurate AFC request messages to an AFC management system for power allowance, thereby optimizing 6 GHz frequency band usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the network device operates at higher Standard Power (SP) transmission levels in the 6 GHz frequency band, then the network performance and bandwidth are improved, but the risk of interfering with incumbent wireless infrastructures increases
Solution Approach 1:
The system performs preliminary location determination and AFC management system consultation before allowing the network device to operate at higher power levels. The access point device determines its location, queries the AFC management system for authorized frequencies and power levels based on that location, and only then operates at the approved higher power level, thereby preventing interference with incumbent systems while enabling improved network performance.
Solution Approach 2:
The system implements a feedback mechanism where the access point device continuously monitors its operation and the AFC management system provides ongoing guidance on authorized frequencies and power levels. This feedback loop ensures that the network device operates within authorized parameters, adjusting power levels dynamically to avoid interfering with incumbent wireless infrastructures while maintaining optimal network performance.
2Object-affected harmful factors
If the network device is restricted to low power indoor (LPI) transmission levels due to proximity to incumbent 6 GHz wireless infrastructure, then interference with incumbent systems is avoided, but the network coverage and performance are degraded
Solution Approach 1:
The access point device autonomously determines its location using available location services, independently queries the AFC management system for authorized operation parameters, and self-configures its transmission power levels without requiring manual intervention. This self-service approach enables the device to optimize its own operation while avoiding interference with incumbent systems, resolving the contradiction between restricted power levels and desired network performance.
3Power
If accurate location information is provided to the AFC management system, then the network device can operate at higher power levels in authorized frequency bands, but the system complexity and location determination requirements increase
Solution Approach 1:
The system introduces an intermediary AFC management system that handles the complex location determination and frequency allocation logic remotely. The access point device simply provides its location to this intermediary system, which then calculates the authorized frequencies and power levels based on the location data and incumbent system database. This intermediary approach reduces the complexity at the access point device while enabling higher power operation.

AI summary
Inconsequential events, such as power outages in an area or an inadvertent disconnection, can cause a network device to send an AFC request message for a power allowance even if not necessary as no change in location has occurred and the required periodic power allowance time period has not expired. An enhanced network environment is provided by a location integrity system that detects a change in location of a network device. The location integrity system determines a baseline location and one or more baseline location integrity parameters associated with the network device. The one or more baseline location integrity parameters are used to determine the change in location of the network device when a power allowance event occurs. The location integrity system only sends or issues the periodic AFC request message when required due to expiration of the periodic power allowance time period or the network device has change location.
