'Passive Wi-Fi' researchers promise to cut Wi-Fi power by 10,000x

Mark Hachman | Feb. 25, 2016
A startup, Jeeva Wireless, plans to commercialize the technology.

The problem is that a passive Wi-Fi system also means that the passive sensor can’t call for attention, or signal the router that it’s ready to transmit data. Instead, routers will have to “order” the passive Wi-Fi device to send data at a given time. That’s not a big deal, although the latency might be a bit higher than normal.

In any event, the promise of passive Wi-Fi is still a couple of years off. But it’s a possible future that looks more and more intriguing as we use our mobile devices ever more frequently.
