A Review on Wi-Vi Technology
Abstract: Wi-Vi is a new emerging technology that captures moving objects behind a wall or obstacle. Previous attempts used array of spaced antennas to track the moving objects through walls. This would be very expensive and bulky. So, in its place Wi-Vi is used which uses only one receiver. Wi-Vi technology is similar to radar and sonar imaging. But Wi-Vi uses very low power Wi-Fi signals for the transmission. The Wi-Fi …
