Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current designs for Wi-Fi 6E standard power access points, which require GPS for automated frequency coordination to avoid interference with existing 6 GHz users, are inefficient due to GPS ineffectiveness indoors, leading to cumbersome installations and potential interference issues.
Innovation Solution
A communication system and method utilizing a positioning device with a GPS module and short-range wireless communication, such as Bluetooth Low Energy (BLE), to wirelessly connect with network devices like routers and extenders, enabling accurate location information broadcast for frequency management without the need for physical GPS antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS technology is used for location information in AFC system, then frequency coordination compliance is achieved, but indoor GPS effectiveness is significantly diminished
Solution Approach 1:
A positioning device acts as an intermediary between the network device and GPS satellites. The positioning device receives GPS signals and transmits location information to the network device via wireless communication (Bluetooth/Wi-Fi), enabling AFC compliance without requiring direct GPS reception at the network device
Solution Approach 2:
The system separates the GPS reception function from the network device function. The positioning device handles GPS signal reception and processing, while the network device handles frequency coordination communications, allowing each component to be optimized for its specific function
2Measurement precision
If GPS antenna cable connection is required for each router or extender, then location information can be obtained, but installation becomes cumbersome and aesthetically unappealing
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The positioning device transmits location information to the network device via Bluetooth or Wi-Fi, eliminating the need for physical GPS antenna cables connected to each device
Solution Approach 2:
The positioning device serves as a centralized intermediary that collects GPS data and distributes it wirelessly to multiple network devices, eliminating the need for each device to have its own GPS antenna and cable connection
3Power
If standard power APs are used for both indoor and outdoor Wi-Fi use, then higher power levels and greater propagation ability are achieved, but potential interference with existing 6 GHz users increases
Solution Approach 1:
The system uses AFC feedback mechanisms where the positioning device provides accurate location information to the frequency management system, which then returns coordinated frequency information to the network device, ensuring high-power operation without interfering with existing services
Solution Approach 2:
The system performs preliminary frequency coordination through the AFC system before the network device begins high-power transmission. The positioning device enables this by providing accurate location data in advance, allowing the frequency management system to pre-allocate non-interfering frequencies
