AT&T's LTE Tests: The Lab Is Not the Real World

4:05 PM -- There's a minor flap today in the techie-sphere today about how AT&T Inc. (NYSE: T)'s 4G network could blow away Verizon Wireless 's current offering by providing 28.87Mbit/s downlinks and 10.4Mbit/s uploads.

This is based on a demonstration shown to GigaOM at the operator's lab in Plano, Texas. Stacey Higginbotham reported that AT&T is using multiple input and output (MIMO) antennas and running the "real world" demos over both 700MHz and 1700/2100MHz AWS spectrum.

Higginbotham pointed out that "sharing those speeds with others on a cell tower will bring them down." This has led many to wonder if AT&T will offer faster LTE than Verizon.

What seems to have been forgotten is that Verizon was getting download speeds of 50 to 60Mbit/s on its initial tests. So it might be just as realistic to ask if AT&T's network will be slower than the 5 to 12Mbit/s average downloads offered over the live Verizon 4G LTE network. (See Real-World LTE and WiMax & LTE Meet the Real World.)

In reality, of course, it is impossible to say for sure what AT&T's average LTE speeds will be when the data rubber meets the fat-pipe road later this year. They're likely, however, to be similar to Verizon's, if AT&T is launching in 700MHz band with a 2-by-10MHz channel arrangement.

Remember that even if -- or, more likely, when -- AT&T gets its hands on T-Mobile US Inc. 's AWS spectrum, that means it is getting another 20MHz swath nationwide to use for LTE. Where that could get potentially interesting is if AT&T does some channel-bonding tricks with its own AWS spectrum to bump up speeds in certain areas.

That kind of science project is probably at least a couple of years away, though.

Dan,


 


Both Verizon and AT&T are 10 + 10 FDD LTE solution at 700Mhz. So, why should one be faster than another??


Thanks..

Dan,


It is possible that AT&T use a better device aka LTE device with higher categories biut Verizon could deploy the same device too.


Thanks.

That's what I'm saying, in response to lots of reports about how the AT&T will be faster...

Yep, they can both tweak for slightly improved performance but the 10X10 channel thing is always going to be a gating factor.
