Passive Wi-Fi: Bringing Low Power to Wi-Fi Transmissions

With Passive Wi-Fi, we demonstrate for the first time that one can generate 1-11 Mbps Wi-Fi transmissions while consuming 3-4 orders of magnitude lower power than existing Wi-Fi chipsets. These Wi-Fi transmissions can be decoded on existing Wi-Fi devices such as routers, smartphones and tablets, while consuming 15-60 microwatts of power. This translates to 10000x lower power than existing Wi-Fi chipsets and 1000x lower power than Bluetooth LTE and ZigBee. The ultra low power nature of Wi-Fi can bring true internet connectivity to the sensor network and IoT space.
