Alphabet’s Google unit won approval from US regulators to deploy a radar-based motion sensing device generally known as Project Soli.

The Federal Communications Commission (FCC) said within a order late on Monday so it would grant Google a waiver to function the Soli sensors at higher power levels than currently allowed. The FCC said the sensors can even be operated aboard aircraft.

The FCC said your decision “will serve anyone interest through providing for innovative device control features using touchless hand gesture technology.”

A Google spokeswoman couldn’t immediately inquire into Tuesday, citing the newest Year’s Day holiday.

The FCC said the Soli sensor captures motion inside a three-dimensional space having a radar beam to allow touchless control over functions or features that can benefit users with mobility or speech impairments.

Google says the sensor permits users to press an invisible button regarding the thumb and index fingers or simply a virtual dial that turns by rubbing a thumb from the index finger.

The company states that “even though these controls are virtual, the interactions feel physical and responsive” as feedback is generated by way of the haptic sensation of fingers touching.

Google says the virtual tools can approximate the truth of natural human hand motion and also the sensor can be a part of wearables, phones, computers and vehicles.

In March, Google asked the FCC allowing its short-range interactive motion-sensing Soli radar to perform within the 57- to 64-GHz frequency band at power levels consistent with European Telecommunications Standards Institute standards.

Facebook raised concerns with the FCC which the Soli sensors operating inside the spectrum band at higher power levels probably have issues coexisting compared to other technologies.

After discussions, Google and Facebook jointly told the FCC in September they agreed the sensors could operate at beyond currently allowed power levels without interference but at lower levels in the past proposed by Google.

Facebook told the FCC in September not wearing running shoes expected a “variety valuable cases to develop with respect to new radar devices, including Soli.”

The Soli devices can be operated aboard aircraft but must still abide by Federal Aviation Administration rules governing portable gadgets.
