Access Point Power Control for Multi-Protocol Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices operating in standard power mode may exceed legal transmission power limits due to the sum of transmission powers across different communication protocols, necessitating a solution to maintain compliance while allowing standard power operation.
Innovation Solution
An access point determines a device's location and adjusts transmission powers across various communication protocols to ensure the total power does not exceed regulatory thresholds, instructing the device to reduce specific transmission powers as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the device uses higher transmission power in standard power mode, then the transmission performance is improved, but the total transmit power may exceed legal regulations
Solution Approach 1:
The access point performs preliminary determination of the device's location and calculates the total transmit power before allowing standard power mode operation. This preliminary action enables the system to prevent excessive transmission power from causing harmful effects while still allowing high power operation when safe.
Solution Approach 2:
The access point continuously monitors the device's location and transmission power levels, providing feedback to control the WiFi radio's operation. This feedback mechanism ensures that the total transmit power remains within legal limits while allowing standard power mode operation when conditions permit.
2Object-affected harmful factors
If the device operates in low power mode, then the total transmit power remains within legal limits, but the transmission performance is reduced
Solution Approach 1:
The system dynamically adjusts the device's operating power mode based on real-time location determination and total transmit power calculations. The access point can switch between low power mode and standard power mode depending on the device's location and environmental conditions, optimizing both compliance and performance.
3Object-affected harmful factors
If the access point determines device location and controls transmission power, then legal compliance is achieved, but the system complexity increases
Solution Approach 1:
The access point performs multiple functions including location determination, total transmit power calculation, and WiFi radio control through a single integrated system. This multi-functionality approach reduces overall system complexity by consolidating control mechanisms that would otherwise require separate systems.

AI summary
The present disclosure describes a wireless network that reduces a total transmission power of a device so that the device can operate in the standard power mode. An access point includes a memory and a processor communicatively coupled to the memory. The processor determines a location of a first device, determines, based on the location of the first device, that the first device is allowed to transmit using a first amount of power for a WiFi radio of the first device, and, in response to determining that a total power transmitted by the first device would exceed a threshold transmission power if the first device transmitted using the first amount of power, reduces a power transmitted by at least one radio of the first device so that the first device is allowed to transmit using the first amount of power for the WiFi radio of the first device.
