Wireless Fidelity or Wi-Fi, has completely transfigured wireless networking
by offering a smooth connection to the internet and networks, particularly when
dealing with enclosed environments. As with the majority of wireless
technology, it functions through radio communication. This makes it possible
for Wi-Fi to operate effectively close to an Access Point. However, a device's
ability to receive Wi-Fi signals can vary greatly. These discrepancies arise
because of impediments or motions between the device and the access point. We
have creatively used these variances as unique opportunities for applications
that can be used to detect movement in confined areas. As this approach makes
use of the current wireless infrastructure, no additional hardware is required.
These applications could potentially be leveraged to enable sophisticated
robots or enhance security systems.
