Based on the AWS auctions, there are 5mhz and 10mhz channels available.


Well, yes, sort of. Those are actually AWS licenses or blocks, and they do come in 5 MHz x 5 MHz and 10 MHz x 10 MHz bandwidths, otherwise known as 5 MHz FDD and 10 MHz FDD, respectively.

Tofuchong said:
Based on T-Mobile's current spectrum holdings on the FCC website, they have only 5Mhz AWS channels in use in most areas they have 3G/4G connectivity. The Majority uses only one single 5mhz channel.


No, that is wrong. In most major markets, T-Mobile is running DC-HSPA+ 42, which requires 10 MHz FDD (or two adjacent 5 MHz FDD blocks).

Tofuchong said:
Based on that, it will be very, very difficult for them to keep the AWS network running unless they get a massive amount of new AWS spectrum, which is possible.


Following several AWS spectrum transactions over the past year, most markets will be fine, will get 5 MHz FDD or 10 MHz FDD LTE. Yes, T-Mobile does have some problem markets where it is going to face some difficulty allocating or acquiring spectrum to deploy LTE currently. But T-Mobile is not going to take all AWS W-CDMA out of service any time soon to solve that problem.

On some of this, you may just have to trust me. I have been studying wireless spectrum allocation for over 10 years, and I am well known online as something of a spectrum guru.

If you like, you can view the spreadsheet that I put together last year of T-Mobile's AWS spectrum holdings in the top 100 markets:
