AFC Location Range Requests for Faster 6 GHz AP Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of obtaining authorization for APs to operate in the 6 GHz frequency band is time-consuming due to the requirement of collecting and reporting precise GPS data, which can take up to sixteen minutes for each AP, especially in large enterprise WLAN deployments.
Innovation Solution
APs determine a location range based on a reduced number of GPS samples and send this range to a server for frequency coordination, using a previously stored GPS data if the location is unchanged, or collect additional samples if the location has changed, thereby reducing the time needed to obtain authorized channels and power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise GPS data collection is performed for AFC authorization, then the accuracy of frequency coordination is improved, but the time required for AP activation increases
Solution Approach 1:
The system performs preliminary GPS data collection and stores location information before AFC authorization is needed. When an AP needs to activate in the 6 GHz band, the controller checks if previously collected GPS data is still valid (within a threshold time period). If valid, the stored location information is reused, avoiding the need to collect new GPS data and significantly reducing activation time.
Solution Approach 2:
Instead of collecting GPS data continuously or at very high frequency, the system collects GPS data at partial intervals and determines whether the collected data is sufficient by comparing it against a threshold time period. This partial action approach maintains acceptable location accuracy while reducing the overall time and resources spent on GPS data collection.
2Reliability
If GPS data is collected frequently to ensure location accuracy, then the reliability of frequency coordination is improved, but the energy consumption increases
Solution Approach 1:
GPS data is collected preliminarily and stored for future use. The system determines whether previously collected GPS data remains valid by checking if it falls within a threshold time period. This approach ensures frequency coordination reliability by using recent location data while significantly reducing energy consumption compared to continuous GPS collection.
Solution Approach 2:
The system implements periodic GPS data collection rather than continuous collection. GPS data is gathered at specific intervals, and the controller determines whether the collected data is still sufficient for accurate frequency coordination by comparing it against a threshold time period. This periodic approach maintains coordination reliability while reducing energy usage.
3Measurement precision
If complete GPS data collection process is followed for each AP, then the accuracy of AFC response is improved, but the productivity of WLAN deployment decreases
Solution Approach 1:
The system collects and stores GPS data preliminarily before AFC authorization is required. When deploying APs in the 6 GHz band, the controller checks whether previously collected GPS data is still valid within a threshold time period. If valid, the stored data is reused, maintaining AFC response accuracy while dramatically speeding up the deployment process.
Solution Approach 2:
The system performs partial GPS data collection by determining whether collected data meets a threshold time period requirement. This partial action approach ensures sufficient accuracy for AFC responses without requiring complete or excessive data collection, thereby improving WLAN deployment productivity.

AI summary
In implementations of the present disclosure, a solution for requesting an AFC response is provided. An access point (AP) collects a first number of location samples of the AP from a positioning system and determines a location range of the AP based on the first number of the location samples and sends the location range to a server for frequency coordination. If a location of the AP is unchanged, the AP may receive at least one available channel and power from the server. If the location of the AP is changed, the AP may collect a second number of location samples of the AP from the positioning system, and update the location range of the AP based on the second number of location samples. In this way, the time for obtaining the authorized channel and power by Federal Communications Commission (FCC) can be reduced.
