Typical capabilities include: Fixed channel selection TX power configuration Bandwidth and modulation selection RX-only mode (disable transmission) Continuous transmission mode These capabilities are required for both wireless interfaces when multiple radios are integrated. Test Mode Implementation RF test mode is typically implemented based on vendor documentation. In this case, the implementation follows:https://toorun.dev/posts/linux-wifi-tx-power-regulatory-configuration/Sat, 29 Nov 2025 12:30:00 +0000https://toorun.dev/posts/linux-wifi-tx-power-regulatory-configuration/WiFi TX Power Configuration Overview WiFi configuration typically allows runtime control of parameters such as channel selection. However, TX power is not always dynamically configurable and may require configuration during driver initialization. This is done by providing a TX power configuration binary to the driver. TX Power Configuration Flow The general workflow: Generate TX power configuration binary\ Place it in firmware path\ Load driver with configuration\ Verify applied limits Generating TX Power Configuration A configuration file is used to generate a binary representation of TX power limits.
