The Atheros CSI Tool consists of two main components:
The tool is designed specifically for (e.g., AR9280, AR9380, AR9580). These chips were chosen because they expose raw channel estimation data to the driver level—something most Broadcom, Intel, and Mediatek chips lock away in firmware. atheros csi tool
To use the tool, you generally need specific hardware. It was originally developed for the Qualcomm Atheros AR9344 and AR9580 chipsets. Most researchers use the TP-Link WDR4300 or similar routers, or specific mini-PCIe cards like the Atheros AR9380 installed in a Linux-based laptop or PC. The software side involves a modified Linux kernel driver and a userspace application to log the collected data into files for post-processing. The Atheros CSI Tool consists of two main
Standard Linux drivers ( ath9k ) process the CSI data, use it internally for equalization and rate adaptation, then discard it. The Atheros CSI Tool patches the ath9k driver to: It was originally developed for the Qualcomm Atheros
