Review on Wi-Vi Technology

Abstract: Wi-Fi is a popular technology which allows an electronic device to connect to the internet wirelessly using radio waves. Wi-Fi signals are nothing but the information carriers between transmitter and receiver. Wireless Vision (Wi-Vi) is a new technology similar to the same concept of Wi-Fi which enables seeing through walls with the help of Wi-Fi signals. Wi-Vi allows us to track moving humans through walls as well as behind closed doors. Wi-Vi's operation does not require any access to any device on the other side of the wall. Wi-Fi can also enable us to see moving objects through walls and behind closed doors. So particularly, we can use such signals to identify the number of people in a closed room and their relative locations also.
