Google's mysterious product has been approved by the Federal Communications Commission (FCC).

The listing is particularly intriguing because it contains almost no details at all about what the product is.

As Android Police discovered, the application describes the product as a "wireless streaming device" with a model number of GJQ9T. In fact, the site speculates that a recent Chromecast with Google TV was approved by the FCC last August with a similar model number, GZRNL, and that a new Chromecast may be in the works at this time.

But equally, there is reason to be skeptical of this claim: the FCC listing for the Chromecast with Google TV described it as an "interactive media streaming device," not a "wireless streaming device."

In fact, the truth may be more prosaic. Just because the term "streaming" has become synonymous with video-on-demand among users is no guarantee that that is what is meant here, and streaming could simply refer to video fed to the device via a local network, for example via a security camera.

That is the theory of 9to5Google. The site points out the similarity to a listing that appeared in March, speculating that it was one of the new Nest cameras announced last week. By the site's count, we have only seen three related FCC listings, so this could be an application for one of the four devices already confirmed. [Once the devices start arriving, a simple comparison of the model numbers to the listings will give us the answer. But for now, it's a mystery, and hopefully Google has something new and unannounced to make this fall's Google Pixel 6 Made by Google launch party even more exciting.
