WiFi traffic is ubiquitous. Between video game consoles, portable computers, smart phones, and even some desktop computers, the vast majority of consumer electronics have WiFi capabilities. Occasionally, these devices will require direct, ad-hoc WiFi connections in such a way that communication over the Internet, or even a single hop, is impossible. In such cases the only options for increasing communication range are devices such as WiFi repeaters or upgrading device antennas. Depending on the device, this can be difficult or impossible to do. These limitations create a need for the ability to expand a WiFi network in a data-agnostic way that supports a longer range than repeaters or antenna upgrades allow.

To satisfy these conditions, we created a set of programs that capture WiFi traffic and relay it to a remote location. The programs are designed to allow devices in remote locations to communicate with each other without the use of proxies, VPNs, or similar technologies that may require special device configurations. Because raw WiFi frames are captured and retransmitted, devices which require direct WiFi connections can have traffic rerouted to a remote location without any configuration requirements on the local device and the entire process is completely transparent to the devices that utilize it. We test several applications to prove viability of the system, and also offer some other potential applications and suggestions for future work.
