AFC Proxy Configuration for Low-Power 6 GHz Transmitters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing configurations of low power indoor access points operating in unlicensed 6 GHz spectrum risk causing interference to incumbent microwave links due to the lack of effective frequency and power coordination, particularly as they are not required to communicate with AFC systems for channel and power limit information.
Innovation Solution
A system and method for configuring low power indoor transmitters, including determining their location and receiving frequency channel and power limit data from an AFC system, to minimize interference with incumbent microwave links by employing an AFC proxy and configuration service that translates and adjusts channel and power settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If low power indoor access points operate in unlicensed 6 GHz spectrum without AFC system communication, then device complexity and ease of operation are improved, but harmful interference to incumbent microwave links increases
Solution Approach 1:
The patent introduces an intermediary AFC proxy that mediates between the low power indoor access point and the AFC system. The access point communicates with the proxy instead of directly with the AFC system, allowing indirect frequency coordination while maintaining simplified operation for the access point itself. The proxy translates and adjusts channel and power settings to prevent interference to incumbent microwave links.
Solution Approach 2:
The system enables self-service configuration where the access point automatically receives frequency channel and power limit data through the proxy without requiring manual configuration or direct AFC system communication. The configuration service automatically translates and adjusts settings based on location and regulatory requirements, allowing the access point to self-configure while still preventing interference.
2Object-affected harmful factors
If frequency coordination services are provided to low power access points, then interference protection is improved, but device complexity and operational requirements increase
Solution Approach 1:
The AFC proxy acts as an intermediary that simplifies the frequency coordination infrastructure. Instead of requiring complex direct communication between access points and the AFC system, the proxy handles all frequency coordination tasks, translating regulatory requirements into simple configuration parameters that access points can easily implement.
Solution Approach 2:
The system uses configuration services that create simplified copies or representations of the complex AFC system requirements. The proxy translates detailed frequency coordination data into simplified channel and power settings that access points can directly apply, effectively copying the essential protective function without requiring the full complexity of the original AFC infrastructure at each access point.
