openwifi: 802.11a/g/n maturity

Wi-Fi has become ubiquitous in modern society. While many people might assume that the Wi-Fi chip in AP, mobile devices, and computers is a dumb device that merely sends and receives packets over the air, the reality is far more complex. Even the most affordable Wi-Fi chips are sophisticated heterogeneous computing systems, as highlighted by many researchers and hackers. These chips contain multiple types of firmware and silicon fabric working together. The lack of open-source Wi-Fi chips and the transparency of commercial Wi-Fi chips have raised many security concerns: The security threats over Wi-Fi have emerged for years. Openwifi (https://github.com/open-sdr) aims to address this issue. It is the first open-source soft-MAC Wi-Fi chip/FPGA design, initially released at the end of 2019, with 802.11n added in 2020. As more users, researchers, and hackers engage with the project, they have identified issues related to stability, data rate, and communication distance. This maturity-elevating project aims to tackle these issues through improvements in the Linux driver, FPGA, and RF control. The enhanced version will be comparable to commercial Wi-Fi4 chips, such as the ath9k series, and will be capable of operating in more realistic electromagnetic environments rather than just short-range, controlled environments. These advancements will facilitate broader adoption of the project and lay a solid foundation for future developments, including the creation of a real chip.
