-Fi), is being commercialized by a derivative company Jeeva Wireless. Passive Wi-Fi uses a back-scattering Wi-Fi signal to connect a battery-free device to a traditional device, such as a computer or smartphone. In the test, the passive Wi-Fi prototype transmits data to 100 feet, enabling a wall-through connection. Doing so requires changing the Wi-Fi access point software to produce an additional signal for use by passive Wi-Fi devices, which can sli
