A recently discovered Federal Communication Commission filing suggests that Google is currently developing an upgraded version of the Google Glass.
The filing was first picked up by Droid Life and shows that the device is called GG1 which started speculations claiming that it might mean Google Glass. The device has a full FCC label that reads "FCC ID: A4R-GG1."
The most interesting part of the filing is the inclusion of 5GHz and 2.4 GHz Wi-Fi support as well as Bluetooth connectivity. Additionally, the Wi-Fi connectivity follows the 802.11 a/b/g/n/ac protocol.
Based on the FCC filing, the device also has a rechargeable but non-removable battery, AC charger and a USB cable that functions as a "path for charging and data transfer" when connection to a PC.
Google has yet to announce whether or not it has plans to release an updated version of the Google Glass. However, many tech websites speculate that Google is busy applying for patents for a high-tech device.
There are speculations pointing to a Google Glass Enterprise Edition or simply called EE. The Enterprise Edition is said to incorporate larger prism display and an Intel Atom processor which will offer significant processor speed upgrade. If this is true, the Enterprise Edition will solve the eye strain problem caused by the smaller prism in the Google Glass Explorer Edition.
According to 9 to 5 Google, the Google has been testing several prototype of the Enterprise Edition since January. The device's battery life and heat management received some minor improvements.
On the other hand, a recently awarded patent to Google suggests that the upcoming Google Glass will have a feature that allows its user to take pictures by using hand gestures.
