Wi-Fi is a popular technology that allows an electronic device to connect to the Internet wirelessly using radio waves. Wi-Fi signals are nothing more than the carriers of information between the transmitter and the receiver. Wireless Vision (Wi-Vi) is a new technology similar to the same concept of Wi-Fi that allows you to see through the walls with the help of Wi-Fi signals. Wi-Vi allows us to track human beings moving through walls as well as behind closed doors. The Wi-Vi operation does not require any access to any device on the other side of the wall. Wi-Fi also allows us to see moving objects through walls and behind closed doors.
Wi-Fi signals are typically carriers of information between a transmitter and a receiver. In this article, we show that Wi-Fi can also extend our senses, allowing us to see moving objects through closed walls and doors. In particular, we can use such signals to identify the number of people in a closed room and their relative locations. We can also identify simple gestures made behind a wall, and combine a sequence of gestures to communicate messages to a wireless receiver without carrying any transmission device. The document presents two main innovations. First, it shows how MIMO interference cancellation can be used to remove reflections from static objects and focus the receiver on a moving target. Second, it shows how a human being can be traced by treating the movement of a human body as a set of antennas and tracking the resulting RF beam.
Fantasies related to X-ray visions; Comic books and science fiction films are finally being explored. This article is mainly investigating Wi-Fi signals with advanced MIMO communications capturing the movements of humans behind the walls. In this technology, the most difficult part is the reflection of the wall instead of the reflections that form the object. Due to the reflection of the wall, the variations of minutes that cross the object avoid being tracked. This behavior of the object is known as "Flash Effect". Multi-GHZ transmission systems are required to separate. The objective of this work is to allow a technology to see through the wall that is low bandwidth, low power, compact and accessible to non-military entities. To this end, the document introduces Wi-Vi, a transparent device that uses Wi-Fi signals in the 2.4 GHz ISM band. Wi-Vi is limited to a 20 MHz Wi-Fi channel and avoids bandwidth solutions Wide used today to solve the flash effect. It also has the large antenna array, typical in past systems, and instead uses a smaller 3-antenna MIMO antenna.
