Google has a "next generation personal communication device" in testing, according to a document held by the US Federal Communications Commission (FCC).
Google is asking for permission from government regulators to break with convention and test its new device outside its labs.
Instead it wants to put the prototypes through their paces on Bluetooth and Wi-Fi networks in the homes of 102 Google employees.
The testing, which is for the purpose of assessing the "throughput and stability of the home WiFi networks that will support the device" will be done by employees in Mountain View, Los Angeles, New York and Cambridge (Massachusetts).
The document submitted to the FCC says that Google itself is the manufacturer of the device which is "in the prototyping phase."
It may be something that never makes it into our own homes, but Google has been steadily diversifying its efforts in a way that could see it in every corner of our lives.
For instance, it has been increasingly making steps into the world of physical rather than virtual product offerings, firstly with its takeover of Morotola, but also with its futuristic AR Glasses project.
It's also expanding into the world of the ISP, laying its own fibre-optic network in Kansas City.
