In my post about Google’s latest experimental radio application, I observed it seemed incomplete. Yesterday, the FCC sent Google, through its attorney, an email asking for the missing information:

Google responds to FCC request for more info about experimental radio project
Saturday, January 26th, 2013Google’s “confidential” test might be a super-dense LTE network using Clearwire’s spectrum
Wednesday, January 23rd, 2013Google filed an application at the FCC last week seeking permission to conduct testing of an experimental radio system. Portions of the application and accompanying exhibits have been designated confidential and are thus not available to the public. Even the request for confidential treatment has been redacted. Let’s try to infer what’s happening from the information available.
Deloitte’s mobile-broadband spectrum policy primer
Monday, October 15th, 2012Deloitte recently issued a new report on mobile broadband. It positions the U.S. as number-one and offers tips to keep it there, some more useful than others. There’s not much new for the mobile broadband expert. The collection of various mobile-spectrum policy issues into one document, however, could be useful to some, especially to those new to the field. Early on, Deloitte promises suggestions for improving U.S. spectrum policy; the suggestions, however, turn out to be mostly things we’ve heard before. There are a few problems with the report, discussed below, that readers should keep in mind.
Qualcomm outlines vision of 1000x mobile capacity increases
Wednesday, August 29th, 2012In the first of a series of webinars, Qualcomm today began reporting on the results of its “1000x Data Challenge,” an initiative to meet what it sees as the need, someday, to increase mobile capacity 1000-times. The webinar, conducted by Rasmus Hellberg, Qualcomm’s Senior Director of Technical Marketing, was an overview. He discussed spectrum, small cells, and other techniques to increase capacity. More-detailed webinars on each of these are forthcoming: spectrum initiatives on September 18, small cells and heterogeneous networks on October 18, and more efficient networks, applications, and devices on November 14. Today’s webinar should be posted tomorrow, and a white paper should appear in about a week.
4G Americas Scenario Shows Mobile Data Growth Tapering Off
Wednesday, May 16th, 20124G Americas, a wireless industry trade association representing the 3GPP family of technologies, has released a report looking at broadband devices and applications, and their impact on HSPA and LTE networks. There’s quite a bit of interesting information; here I highlight the discussion on mobile broadband offload and mobile data growth.
Three Invalid Assumptions that Make the FCC’s Spectrum Requirements Model Skew High
Saturday, November 19th, 2011“To generalize, it is often true that studies will be promoted that tend to support the policy inclinations of the Chairman, under whose direction, after all, every draft decision is made.”
“[S]tatistics can lie. But cast as ‘studies’ by commentors, they take on the weight that a decision maker chooses to make of them.”
As a follow-on to its National Broadband Plan, the FCC last year released a Technical Paper intended to validate the Plan’s prediction of a 300 MHz mobile-broadband spectrum deficit by 2014. The Paper describes a spectrum requirements model that totals current spectrum assigned to mobile broadband and applies a multiplier based on expected demand, taking into account expected increased tower density and improvements in air-interface spectrum efficiency. The model’s result is a predicted deficit of 275 MHz in 2014, which rounds to 300 MHz. On the way toward that result, however, the analysis uses just a few of the available data forecasts, ignores offloading of macrocell data to Wi-Fi and femtocells, and assumes the continuation of flat-rate plans for consumers. Some of these oddities I noted in a post at the time. I had hoped the FCC would make the Paper a subject of public comment. That hasn’t happened. So, I’ve looked at the Paper in more detail. I find that when looking at the above factors in a more realistic manner, predicted spectrum requirements go down significantly.
