Dueling Spectrum Charts - Part 2

In a recent post we discussed the spectrum chart duel between FCC and CTIA. Here are some updates.

Fred Campbell, who during the Chmn. Martin era was the chairman’s wireless advisor and then Chief of WTB, has written a blog post on the new FCC spectrum chart report. Fred questions the consistency of the new data with earlier FCC statements in the merger context:

“It appears that the FCC considers the entire 194 MHz of licensed spectrum in the 2.5 GHz band as available for mobile broadband in the US when the ratio of licensed to unlicensed spectrum and international pride are at stake, but only 55 MHz is available when the FCC considers the impact of licensed spectrum aggregation on mobile competition. If the 139 MHz of spectrum the FCC excludes from its calculations when considering mergers is excluded from the international comparison in Table 1 of the report, the total licensed spectrum in the US that is available for mobile broadband drops from 608 to 469 MHz.”

Fred ends his post with

An agency that is truly “focused . . . on facts and data” would not pretend otherwise by manipulating facts and data to satisfy its desired results. Sadly, over the last three years, the FCC has demonstrated it is no such agency.

An exercise for readers is to decide whether the Martin chairmanship was any better on being “focused . . . on facts and data”.

Your blogger was in Japan last week for some speaking engagements. In a talk at ARIB he pointed out the inconsistency of the FCC’s number for Japanese mobile spectrum (500 MHz) and CTIA’s number (347 MHz) and asked which was correct. Fortunately ARIB had just finished a report, in Japanese only, on wireless spectrum use in Japan. The key chart from that report is shown below and indicates 501.2 MHz of commercial mobile spectrum at the moment. So on this point, score 1 for FCC.


On Fred Campbell’s point, I don’t follow merger issues too closely so I would welcome input from others on who is correct.

(I would be glad to share the ARIB report with others who are interested and can digest the Japanese in it.)


Pierre de Vries, in his Deep Freeze 9 blog, has expanded on this post with respect to alternative ways to quantify spectrum use.
