Oh, come on, really?!? The Motorola Photon Q 4G LTE for @Sprint has a physically locked (i.e. non-removable) GSM SIM card? That's terrible!

I'm now halfway moved out of my apartment into my new place. Tomorrow, after class, I should hopefully finish moving... *sigh*

In preparation to move out this weekend, I've been cleaning up my room. I never realized how much stuff has built up for me to throw away...

I'm surprised the TARDIS hasn't shown up at the #2012LondonOlympics. Perhaps the Tenth Doctor is late... again...

So apparently the Google Talk servers are down now...? Gmail chat, Google+ chat, and Google Talk are all non-functional right now...

Finally managed to purchase a Clearwire hotspot! Set up for Atlanta (which I'm going to at the end August), it'll be shipped to me here!

Of course, it also means that these AT&T devices will be able to roam in some Asian markets due to BC5 support. BC6 is easy to add to that.

What will this mean not enough spectrum

I dunno... He does seem to use it everywhere he goes! -

He has a spectrum analyzer, which is basically a device that can pull in radio signals and visually represent them in a way that conveys how the airwaves are being used. -
Okay, something is wrong. Why is the FCC still allowing crippled LTE worldphones on VZW? It's against the 700MHz Upper C block regulations.

It would be interesting to see how it fares against my HP TouchPad and my Samsung Galaxy Tab 10.1...

Australia follows Asia (which is actually called the Asia-Pacific and Oceania region). The Middle East and Africa are using a mix of European and Asian frequencies, so it's a little more complicated. The Americas are using largely the same frequencies, so the US frequencies largely apply to Canada, Mexico, and nearly all of South America (except Brazil, which uses European frequencies too). The exception continent wide is with 700MHz. Just like Asia, most of the Americas will use a different band plan. From what I've heard, the Lower 700 band class 12 will be preserved, but the other bands won't be. I'm hoping that Asia will do something similar, but I'm not holding my breath for that. Nearly all Verizon Wireless LTE handsets support global GSM/WCDMA roaming[1]. [1]: http://www.extremete...ility-with-them

AT&T probably wouldn't be allowed because it has AWS and WCS along with PCS for usage with LTE. The other thing is that AT&T doesn't need to have a network that is too fragmented. Adding AWS-4 to AWS-1, PCS, and WCS would make AT&T devices very expensive compared to everyone else's devices. -
I just got a $2 credit for music from @amazonmp3 and @imdb. Get your credit here: http://t.co/19YrxEtj

AT&T is making it very hard to figure out what exactly its spectrum plan is. AT&T has done a lot of different confusing things in the last several months that make it rather difficult to figure out how AT&T plans it use its spectrum. Plus, with AT&T as the dominant GSM provider, analysts are never worried about it. Also, AT&T will likely not be allowed to purchase S-band spectrum since WCS is now considered usable spectrum[1]. I expect carriers like T-Mobile, Sprint, and U.S. Cellular will aim to buy chunks, if not all, of the spectrum from Dish. As far as I'm aware, Dish is planning on doing the wholesale/direct to market hybrid business with terrestrial LTE. I think Dish may be considering using LTE as a video delivery platform directly to consumers who can't use satellite, and offer broadband through wholesale, but that is speculation on my part.

It's not hard to do handover (I know it's called hand-off officially, but handover is more accurate) between FD and TD LTE. The way LTE handles handover is very efficient and designed to work well with mixed FD/TD environments. As for the Qualcomm chip, there are a few issues. In the United States alone, the following frequencies are being used for LTE by various operators: BC25, BC4, BC26, BC12/BC17, BC13, BC14, and BC41. Europe is using BC3, BC7, BC20, BC38, and BC42. Asia is using BC1, BC3, BC26, BC40, and a totally new band plan for 700MHz that isn't defined yet. Since BC26 encompasses BC5 (UMTS band V) and BC6 (UMTS band VI), the US, South Korea, and Japan would be covered. Japan doesn't use ESMR, it uses a subset of BC5 that was standardized as BC6. BC26 covers all of these. We're screwed on TDD, and we're semi-screwed on FDD. The optimal FDD configuration for breadth of coverage on LTE would require a device supporting BC1, BC25, BC3, BC4, BC12, BC13, BC20, BC26, and BC40. This is not possible. That's four super-1GHz frequencies and four sub-1GHz frequencies. Only the one TD frequency is possible, and it's not even Clearwire's band. Clearwire is using BC41, not BC40 of Asia. BC40 is important because China and India use this frequency.

They need to learn how spectrum is used. >>> WSJ believes Sprint is in trouble, but it really isn't http://t.co/Bf8jy3CG from @ExtremeTech

Someone at Verizon Wireless Marketing screwed up. The new ads are a strange mix of Spanish and English, making them incomprehensible...

Catching up on the new "White Collar" episodes... The first two episodes of the new season are pretty awesome!
