Back in 2013, the Security Scrapbook alerted you to Ambient Backscatter as a developing technology with extreme potential, including electronic surveillance / eavesdropping.
At that time I said, "Ambient Backscatter research is in its infancy. Imagine the possibilities. Technical espionage could see its biggest advancement since the transistor."
Today, Jeeva Wireless, is developing this technology and is about to come out of stealth mode.
The technology is so interesting, NASA has posted Federal contract opportunity NND1710133Q, "a sole source contract under the authority FAR 13.106-1(b)(1)(i)."
Here is the update...
"A group of University of Washington engineers has raised capital to develop and commercialize a power-efficient way to generate WiFi transmissions.
Jeeva Wireless just reeled in a $1.2 million round, co-founder Shyamnath Gollakota confirmed with GeekWire. He declined to provide more details about the cash and how Jeeva will use it, as the Seattle startup is still in stealth mode.
The company’s co-founders are the same UW researchers who co-authored a study last year for a Passive Wi-Fi system that can generate WiFi transmissions using 10,000 times less power than conventional methods.
Not even low-power options such as Bluetooth Low Energy and Zigbee can match the system’s energy efficiency, based on the study that earned the UW team a place on MIT Technology Review’s top-ten list of breakthrough technologies in 2016. With the fresh funding, it appears that the company is ready to commercialize its innovation" more
