Even though Google would prefer to keep its Google Glass wearable display device under wraps, it still needs to comply with the requirements of the Federal Communications Commission in order to distribute the device under non-disclosure agreements among software developers. As a result, FCC has revealed some of the technical specifications of Google’s head-mounted display on its web-site.

As it appears, the prototype Google Glass augmented reality glasses model XEB (FCC id A4R-X1) have Broadcom 2.40GHz 802.11 b/g Wi-Fi and Bluetooth 4.0 low energy radios, power meters/sensors, thermometer, amplified, vibrating speaker that delivers audio and some other electronics components. The Google Glass consists of off-the-shelf components made by Agilent, HP, Sunol and so on.

According to FCC, during testing for compliance “a video stored within the [equipment under test, EUT] was played on the heads-up display with audio running to the vibrating element and transmit [using] the Bluetooth LE mode”. While nothing can be said for sure at this point, but the fact that the video was “stored” on the EUT (Google Glass) means that the unit has some kind of built-in storage and maybe even a kind of application processor. Still, it is more likely that the wearable construction is just a bunch of sensors and antennas that operates like an add-on device for a Google Android-powered device.

Google requested FCC a 180-day confidentiality period for Google Glass augmented reality display, therefore it is hard to expect any additional more or less official information (e.g., photos, user manual, etc.) about the glasses any time soon.

The first version of Google Glass will be available only to software developers who pre-ordered them for $1500 per unit. Commercial version of Google Glass is expected to cost much less and emerge on the market in 2014. Earlier this week Google demonstrated the head-mounted Glass displays to select developers at top-secret events in two venues.

Target applications for the Google Glass include, among other things, taking and sharing photos, checking appointments, accessing maps and the Internet as well as some other, like e-mail, notification center, information updates and so on.
