Google files with FCC for what might be connected-car experiment

Update March 27, 2014: A few days after this application was filed, it was apparently withdrawn. The links below to the application form and exhibits no longer work, and I see no trace of the application. The essential application information is still in my original post below. I don’t know why the application was withdrawn. The application was apparently prepared by an engineer based at a Google office in Seattle. To me, it seemed incomplete in some aspects. Usually, such applications are prepared by Google’s attorneys; I speculate this caught the attorneys unaware, they didn’t like it, and they pulled the application for their review. Look for it to be recast and filed again.

Google yesterday filed an application with the FCC for an experimental radio license that apparently involves connected-car technology. No specific location for the experiment is indicated; it’s to take place in the “Seattle and San Francisco areas.” A total of 10,000 transmitting units are involved, with 5,000 being custom experimental devices manufactured by Google, and 5,000 consisting of off-the-shelf CSR CSR8311 Bluetooth ICs, which the manufacturer describes as the “first Wideband Speech IC qualified for the automotive market” and “the first Bluetooth low energy IC ready for automotive use.” I speculate the IC will be used in combination with the Google device, for a total of 5,000 experimental radio systems. There’s only one frequency band (2402-2480 MHz) and one emission designator (1M00F1D) specified in the application; these parameters are consistent with Bluetooth, so the custom Google transmitter would seem to have Bluetooth-like emissions.

Supporting exhibits are usually filed with experimental applications. Google has done so, but designated them “not available,” presumably invoking confidentiality provisions of the FCC’s Rules. It’s standard FCC practice to have the applicant make the confidentiality request visible to the public. Google has not. Furthermore, from the exhibit descriptions, it appears Google has not even filed a confidentiality request. I expect the FCC to ask Google to do so and to make it public. If there are updates to this application, I’ll update this post.

Positioning LTE Direct against other proximity-aware technologies

LTE Direct, now being standardized in 3GPP as part of Release 12, is a platform for directly discovering and connecting nearby peers. Qualcomm and Samsung sponsored an LTE Direct workshop earlier this year in which several major operators participated. A few days ago Qualcomm made available a white paper, prepared jointly by some of the participants, that summarizes key points from the workshop.

Google Finishing Development of Personal Communication/Entertainment Device

It appears Google is finalizing the design of what it variously calls, in recent FCC filings, a “personal communication device” or an “entertainment device.” It further appears it would be an unlicensed device supporting both Wi-Fi and Bluetooth, and operate at low power in the bands 2400-2483 MHz and 5180-5825 MHz.
