New Google Glass? Company working on mysterious new product known only as 'GG1'

The Federal Communications Commission last week approved a mysterious new Google device that is known only as " GG1."

Many times, FCC documents will indicate what kind of device is receiving approval, but in this case Google asked for, and got, approval for confidentiality.

The new device sports WiFi, Bluetooth and an unchangeable battery. It could be a bunch of things like a new Nest device or a new version of Chromecast. But there are a few clues indicating that it's a new version of Glass, speculates Droid Life, the first to spot the FCC documents.

First of all there's the name: GG1, which could stand for something like Google Glass revision 1. Second, there's an FCC "e-label" in the documents, meaning that the FCC and UL approval label isn't on the device itself but is in the device's software. That e-label is the exact dimensions of screen grab from a Google Glass device.

While Google halted sales of the controversial $1,500 Glass in January, which seemed to indicate that Glass was a dead project, various Google execs including executive chairman Eric Schmidt have been saying Glass is not dead and Google plans to release new versions of it, maybe even by the end of the year.

Back in January, Glass became a standalone unit under Nest CEO Tony Fadell. A few months ago, Google ramped up hiring for the project, indicating that Google may be working on a whole family of wearable products.

Meanwhile, Microsoft has been showing off its promising new wearable technology HoloLens, which will work with Windows 10. It seems unlikely that Google will just let Microsoft run-away with this fledgling wearable market.
