Verizon has one hotspot without CDMA. Future hotspot devices may lack it too. A version of the Spro 2 with Verizon's LTE bands did pass through the FCC, and it does lack CDMA. It'll only support T-Mobile HSPA+ on PCS (1900). You'll see AWS referred to as either "AWS" or "1700" on most spec sheets. AT&T devices support LTE bands 2 and 4, so it'll support LTE fine on T-Mobile. According to the FCC authorization info, it lacks band 12 (which isn't very surprising).

Happy birthday, Robert!

I'm loving the redesign. It's more responsive and definitely easier to find things. I can't wait until it's filled out more and applied to the whole site.

That doesn't make it okay. And before you jump on me about it, yes I'm aware that T-Mobile, AT&T, and Verizon have done this too. Every single spectrum license holder does this, and I still don't believe it's a good thing to allow such wastefulness.

Actually, 2.5GHz is generally allocated for FDD technologies, with the major exception of the China and Japan. Technically, the U.S. allows both, but the licensing configuration makes it tough to roll out FDD unless you want to mix BRS and EBS. In most countries, they follow the preferred ITU Option (option 1), which is set up as follows: 2495-2500 MHz is a guard band for ISM, MSS, and BAS 2500-2570 / 2620-2690 MHz is paired for FDD operation (3GPP band 7) 2570-2620 MHz is allocated for TDD operation (3GPP band 38, but band 41 service can run here too) Internal guards at 2570-2575 MHz and 2615-2620 MHz are recommended to prevent interference This configuration is known as the "IMT Extension" configuration, as it was originally designated for high capacity 3G networks (which is why you can deploy UMTS WCDMA on it). But it is now known as the "IMT Advanced" band, where high capacity 4G networks are to be deployed. Most countries following Option 1 do not bother with allocating the TDD frequencies. In CEPT countries, TDD frequencies are allocated because CEPT recommends it. CITEL (for the Americas) and APT (for Asia and Oceania) do not make the same recommendation, though they do recommend Option 1 configuration. The U.S., China, and Japan technically follow Option 3, which permits mixed FDD and TDD throughout the band, and only mandates a 1MHz guard between ISM/MSS/TLPS/BAS and the 2.6GHz band, so instead of starting at 2495MHz, it starts at 2496MHz (which is why there have been issues launching LTE service on the BRS 1 block). However, China and Japan have set up their allocations and regulatory environment so that significant Band 7 allocations are still possible (though they haven't been done yet). The U.S.' confusingly split regulatory environment makes it difficult (though not impossible) to launch FDD service there. Now, that being said, while 2.6GHz is recommended worldwide under Option 1, 2.3GHz (2300-2400 MHz) is recommended as an all-TDD band. CITEL, CEPT, and APT all recommend 2.3GHz for TDD service, which is designated as Band 40 for LTE. This is live all over Asia and Africa. Latin America and Europe are starting Band 40 deployments now. The U.S. is the only country where it is FDD only, and only a small subset of the band has been allocated for mobile services. That mainly has to do with Sirius XM doing things it shouldn't be doing with its SDARS frequencies (which sit in part of that band) and being permitted to do so. Consequently, WCS is currently set up as an FDD band, but with some work, it could be converted into a TDD band.

Quite a few between Norwalk and Rochester. They had surprisingly decent range, but capacity was lower than full-build sites.

Personally, I've had a similarly good experience in Norwalk, Stamford, and Rochester. Even traveling between Norwalk and Rochester was quite smooth, as I had native access throughout nearly all of my trip up to Rochester and back down to Norwalk last week.

Yes.

3/4/6 sector sites are common in Latin America, Europe, and Asia, which is where the higher minimum carriers are needed. I believe here in the U.S., most are 3 sector only, so you'd just chop off one GSM carrier (21 instead of 22).
