Passive Wi-Fi – Bringing Low Power to Wi-Fi Transmissions
Bryce Kellogg, Vamsi Talla, Shyam Gollakota, Joshua R. Smith have published an research article discussing Passive Wi-Fi transmission that consumes 3 – 4 orders of magnitude lower power than existing Wi-Fi chipsets.
Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets. Building on this, we also present a network stack design that enables Passive Wi-Fi transmitters to coexist with other devices in the ISM band, without incurring the power consumption of carrier sense and medium access control operations
