    Another Power saving Technology for Wi-Fi.

    Unlike Wi-Fi HaLow, this technology makes use of back scatter radiation (similar to some RFID technologies), to power "passive" nodes.

    It is claimed to reduce power requirements by as much as a factor of 10,000.

    IMO, it's like some other power generation schemes based on 802.11 signals and may cause interference for other Wi-Fi networks.

    Still, it's  intriguing.
