This purpose of this project is to benchmark capabilities of monitor mode in different Wi-Fi chips. In monitor mode, all the traffic on the wireless channel can be captured without being associated to an access point and packet injection is also possible in many cases. Since the firmware of Wi-Fi chips is usually closed source and since basic functions like sending and receiving frames and controlling rate/modulation scheme is done by the physical layer, monitor mode provides a breakthrough as it allows us to control these from user space. The outcomes of this work would be of great contribution to the community and can serve as a basis for future research on wireless networking.
