Citigroup Questions Whether US Spectrum Shortage Exists
alphadogg writes "For more than two years, the U.S. mobile industry has warned of an upcoming spectrum shortage, but two analysts at Citigroup don't buy it. AT&T, trade group CTIA and even officials with the U.S. Federal Communications Commission have talked frequently about a coming spectrum crunch, as mobile customers move to data-sucking smartphones and tablets. Smartphones use 24 times the spectrum compared to standard mobile phones, and tablets use 120 times the spectrum, FCC Chairman Julius Genachowski said in a speech on Tuesday. But Citigroup analysts Jason Bazinet and Michael Rollins questioned what has become the conventional wisdom in the mobile industry. The U.S. has plenty of spectrum for mobile broadband, but much of it is in the wrong hands, they said."
In bribes.
They should have sold the frequencies by market area (city, zip-codes, etc.) and not nation-wide.
That's the real crux of the problem.
Now we have large nation-wide companies holding up frequencies in large swathes of the country because they're dedicating their efforts in specific markets where they can charge more.
Had the FCC sold the frequency on a market basis and required it to be used within a reasonable time frame, we wouldn't have these issues.
Citi's report is not wrong, but how they go about counting things is naive at best. The crux of the matter is that there's a lot of crap spectrum that carriers basically got for free or close to it. But before we get too far ahead, let's answer an easier question: what is good spectrum.
Case in point, 194MHz of the spectrum Citi says is available is above 2GHz: "Citigroup's description of 194 MHz available in the Broadband Radio Service (BRS) and Educational Broadband Service (EBS) bands between 2.4 and 2.7 GHz". This also goes hand-in-hand with Citi's weird method of counting spectrum in use: they're multiplying it by the percent of the population that the spectrum covers. "The two used averages to come up with spectrum use estimates; if a carrier has a 10 MHz nationwide block, but is only delivering service to half the U.S. population, the report considers that 5 MHz of used spectrum, Rollins said."
Ultimately the carriers are being wasteful at times, but not nearly to the degree that Citi says they are. The carriers need more national allocations if they're to run a 3rd network simultaneously, and those allocations need to be at least 40MHz wide so that they can operate two sets of wideband (10MHz) LTE channels. Smaller allocations mean that they're going to have to use smaller channels, and that's going to greatly limit network performance.
Hi Bill:
A good amount of that Clearwire spectrum is used for tower-to-tower communications. One unique thing about Clearwire's system is they really don't like to pay for dedicated lines to towers. The normal setup is a few AggPOPs per market which feed, normally 10Gb fiber, to the market's TransPOP which often is colocated with the RDC (Regional Data Center). Each AggPOP will service one to several RF tower rings of three to eight towers, mostly via Dragonwave radios. Of course with tens of thousands of RF sites, there will be some one-offs, but the goal is to have as many tower sites serviced via the AggPOPs as feasible. The system from RF tower to TransPOP is PPB-TE Ethernet.
This allows them, as they are doing now, to lease some of that bandwidth to the towers to other carriers. Clearwire was always envisioned as a wholesaler.
