6 years ago If you want to find answers to your questions you should read my PhD thesis. All 802.11n and 802.11ac Wi-Fi chips should have phy tables that contain CSI information for OFDM modulated Wi-Fi frames.

Hello, under the nexmon framework, you continued to do a tool to extract CSI. However, there are a few things I'd like to learn. 1: I have read the source code of UCODE, and there is no hint of CSI, how do you know where is CSI? Can all BCM wifi SoCs extract the CSI of OFDM? 2: Where is the CSI address? Are all BCM SoCs the same? What's the CSI address of different antennas?

Hello, under the nexmon framework, you continued to do a tool to extract CSI. However, there are a few things I'd like to learn. 1: I have read the source code of UCODE, and there is no hint of CSI, how do you know where is CSI? Can all BCM wifi SoCs extract the CSI of OFDM? 2: Where is the CSI address in D11 core? Are all BCM SoCs the same? What's the CSI address of different antennas?
