Wireless Transmit Power Adaptation via BIOS Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication modules face challenges in optimizing transmit power levels to comply with regulatory safety standards without compromising performance across various platforms and usage scenarios, leading to either undesirable performance reductions or complex logistical issues with multiple module versions.
Innovation Solution
A system where a Basic Input/Output System (BIOS) configures a transmit power level table to dynamically select and limit transmit power based on the platform's operational mode, interfacing with a wireless communication module to ensure compliance with safety tests and adapt to different usage scenarios, while a one-time programmable memory sets a maximum threshold for the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmit power level is reduced to comply with worst case safety scenario, then regulatory compliance is improved, but wireless communication performance deteriorates
Solution Approach 1:
The patent implements dynamic transmit power adjustment by determining operational modes (such as portable or handheld modes) and selecting appropriate power levels from a table of power levels associated with different operational modes. This allows the system to adapt power levels in real-time based on actual usage conditions rather than statically reducing power for all scenarios.
Solution Approach 2:
The system changes the transmit power parameter based on determined operational modes. A table of power levels is maintained with different power values corresponding to different operational modes, and the appropriate power level is selected based on the current mode determination, allowing optimization between compliance and performance.
2Adaptability or versatility
If different versions of wireless communication module are manufactured with different Tx power levels, then adaptability to different platforms is improved, but manufacturing and distribution complexity increases
Solution Approach 1:
The patent makes a single wireless communication module version universal by implementing software-based power level selection through a table of power levels associated with different operational modes. The module can function across multiple platforms and scenarios without requiring hardware variations, as the power configuration is determined by operational mode rather than physical module version.
Solution Approach 2:
Instead of manufacturing different hardware versions with different power levels, the system changes the power parameter through software configuration based on determined operational modes. This allows a single module design to serve multiple platforms while maintaining appropriate power levels for each usage scenario.

AI summary
Generally, this disclosure provides devices, systems and methods for improved transmit power adaptation for platforms with wireless communication capability. A device may include a memory to store a first transmission (Tx) power level and a Tx power determination module to receive a second Tx power level from a device driver, the second Tx power level provided from a Basic Input/Output System (BIOS) associated with a platform hosting the device. The Tx power determination module may further determine a third Tx power level based on a comparison of the first Tx power level and the second Tx power level. The device may further include a radio frequency (RF) transmission module to transmit a wireless signal at the third Tx power level.
