ABSTRACT:
Wi-Fi signals are typically information carriers between a transmitter and receiver. Through this paper we are trying to extend our senses so as to see moving object through the walls and closed doors, under this technology communication is possible by combination of gestures and by messaging without even using the any transmitter. In this paper to innovations are being introduced: (1) Use of MIMO interfacing to nullify the effect of static object and focusing the receiver on a moving target (2) motion of a human body is treated as an antenna and resulting RF beam is tracked. Not much research has been done on this technology but Wi-Vi could be built into a smart phone or a special handheld device and used in search-and-rescue missions and law enforcement. To exemplify, someone walking outdoors at night who thought they were being followed might use it to detect a person behind a fence or around a corner. The key benefits of Wi-Vi over current ways of seeing through walls, such as radar and sonar, are cost, power and size. At the heart of the technology is its encoding scheme, which can be implemented in silicon. Wi-Vi could be built into a cell phone soon, and for not much more than the cost of a regular Wi-Fi module. Bringing wall-penetrating vision to handheld devices could open up a lot more uses for it. Current radar-based systems used in the U.S. military are so big they need to be transported on trucks. Even the Army might need a more portable tool for seeing through walls in certain settings. Because of its low resolution, Wi-Vi could actually enhance people's privacy rather than erode it in some cases.
