M2Z: T-Mobile's interference argument over AWS-3 spectrum flawed
M2Z Networks is working to make T-Mobile USA's interference concerns regarding the 2155-2180 MHz band the FCC wants to auction for free wireless broadband services a moot point. The company, which wants to bid on the spectrum, has pointed out that T-Mobile in the Czech Republic is currently providing broadband services using similar spectrum and similar technical rules to those the FCC plans to adopt for the band.
T-Mobile has been aggressively arguing that time division duplex (TDD) technology would cause a problem if deployed in the U.S. adjacent to its frequency division duplex (FDD) operations in the AWS-1 band. T-Mobile's network in the Czech Republic, however, uses TDD (UMTS TDD technology) in unpaired spectrum and is adjacent to FDD operations within well-established standard power limits and without using spectrum guard bands, said a report from the Czech Telecommunications Office.
"As a former FCC official, I'm also particularly troubled by T-Mobile's selective presentation of information at the FCC about the state of the art in wireless technology and interference management," M2Z CEO John Muleta said in a statement.
The FCC wants to create a 25-megahertz swath of spectrum, known as AWS-3, that would support a nationwide license. The spectrum is referred to as advanced wireless services-3 and would require the licensee to dedicate 25 percent of its network capacity to free broadband service, install a network-based Internet filtering system to block pornography and allow open access to third-party devices and applications. T-Mobile has been the most vocal opponent of the plan.

I understand why they would be afraid of a free broadband service but isn't it illegal to lie to the Federal Government? I know what would happen to me if I hid the ball and lied to the Government -- perhaps a few extra thousand in income that I "forgot" to include on my 1040. But what exactly will happen to T-Mobile? Probably nothing. They can just say "Czech Republic" oops sorry forgot about that. What a joke.

Apparently, John Muleta,CEO of M2Z, is troubled, i.e. losing sleep, over T-Mobile's wise selection, he says "selective", of cold hard facts. So, M2Z throws up a red herring to attempt to change the topic away from a complete different basis for the complaint. The devil is in the details, not erroneous comparisons.

Cold hard facts? T-Mobile wants a 15 MHz or more guardband in the US but 5 MHz works overseas? Oh and by the way, the 5 MHz turns out to be unoccupied spectrum, not guard band. Anonymous, the devil is in the details and all T-Mobile has is a bunch of half truths (and half is being generous). They don't tell the FCC relevant stuff until they get called out. For example, they have a faulty filter in their phones that exacerbates interference concerns and T-Mobile tried to hide that fact from the FCC for months. Sloppy. No wonder they get clobbered by the other wireless carriers.
