Protocol
Thread is an IP-based wireless networking protocol. It relies on a low-power radio protocol called IPv6 over Low Power Wireless Personal Area Networks ("6LowPAN"). Unlike Wi-Fi, which sends large quantities of data and consumes large amounts of power, Thread sends small amounts of data and consumes very little power.
