LTE Advanced and phones

I have a burning question that I cannot find an answer to on the Internet (if that's possible). When sprint gets LTE advanced, will the iPhone 5 and the GS3 support the new features (Carrier aggregation, etc)? And what other phones can use LTE-A?

if I understand correctly they will not.

No phones currently on the market support any of the 'advanced' benefits of LTE Advanced. And no specific device has been advertised in the future to support it either. So it is unknown which will be the first device.

 

As for 4x4 MIMO it may be a few years before technology advances to put that many antennas in a smartphone. That aspect of LTE Advanced may be only for larger devices like tablets for some time. Carrier Aggregation can be done now on the device side, but CA with three LTE bands may be a stretch.

 

We just don't know much about LTE Advanced and device development yet. I haven't seen anything out of CES yet.

Ah okay well LTE is amazing anyways when I can get it :)

Guess I gotta be happy with the 2x1 MIMO that the iPhone 5 does (yes I'm happy with it already :P )

 

On a side note wow you guys reply FAST o.O

The new Snapdragon 800 supports carrier aggregation, not sure about the other features (bigger MIMO, etc).

I expect CA capability to start showing up in devices this year. But will anyone be deploying any CA network side anytime soon? Additionally, the 4x MIMO issue is more of a device real estate problem than anything. Sticking another two diverse antennas in a smartphone is a tall order, especially for carriers already employing several bands. It will likely be employed in tablets and hotspots first.

There is some upcoming models that will be announced on January 30th by RIM in which they will have LTE-Advanced specs In them. BB10 phones will have the abilities for LTE-Advanced.

Which features? Certainly not 4x4 MIMO, and probably not even CA.

Something that InterDigital has in there portfolio. RIM expanded there licenses to cover LTE-Advance with them.

So the new QUALCOMM MDM9x25 baseband chipsets are LTE-Advanced. They are sampling and first UE should be popping out in a few months time. They'll be able to do carrier aggregation, they're Cat 4 chipsets capable of 150mbps on the downlink.

 

But to achieve 150mbps, you need a carrier to deploy either 2x20Mhz slice in a given Release 8/9band, or to deploy Release 10 network and aggregate two 10Mhz bands. Only T-Mobile will have Release 10 network, and only Verizon can currently deploy 2x20Mhz in the AWS band that could achieve 150mbps speeds.

Also keep in mind that a single 2x20Mhz slice will drain much less battery than aggregated 2x2x10Mhz carriers.

 

Verizon announced during CES that this year they'll be deploying AWS as a separate carrier for capacity, and in 2014 they'll aggregate it with their existing 700c.

 

Then 4x4 MIMO is clearly an issue on UE side, but also the base station has to be upgraded for higher order MIMO, which no one but T-Mobile even mentions in their presentations.

 

Other features like HetNet, Relay, CoMP all require at least Rel 10 network side upgrades. Those features are not even available to deploy really.

 

So it's fair to say that this year we will first see LTE-A capable Cat 4 UE, as soon as this or next quarter.

Sprint/clear will be able to do that with TD-LTE 40mhz carriers should they choose to do that. Sprint will also be deploying release 10 this year also but it is unlikely that we will see that kind of bandwidth used.

 

I do like the idea of having a release 10 network aggregating the PCS G block carrier with the SMR carrier to effectively make a higher capacity network (due to PCS spacing) able to exceed Verizon and AT&T's network speeds and match their coverage.

 

While I think beyond 20mbps is just excessive, there was also a time when I said no one could possibly need more than a 2 ghz pentium 4 processor in a desktop.

*Looks at AMD Anthlon X64 CPU's performance, price, TDP, low temperatures, good overclocking*

I'll guess I will still keep with my Intel I7-3770K which has a tdp of only 77 watts at stock speeds up to 3.9 ghz.

I'm just trying to imagine any carrier being able to actually have a network band backhaul to handle speeds that fast. The air link will be much faster than the network can support.

Well in big metros like NYC I can see Verizon having proper backhaul as this is the market where I'm able to max out the LTE sector at 72mbps.

On cell macros with 3+ sectors, I can't imagine them running less than 500mbps fiber feed in NYC. They can remotely dial up/down on demand.

In some smaller markets it'll be interesting to see how will they handle the backhaul.

T-Mobile is in a similar position. Sprint doesn't need massive backhaul for 2x5Mhz LTE at the moment but that'll change.

I have no clue what's AT&T doing as they only care what investors think... It wouldn't surprise me if they keep being stingy lol.

But I thought sprint said that their back haul could handle LTE-advanced?

That has not been said. However, their backhaul is scalable. But 100-150Mbps is going to be tough for any carrier to deploy over an entire network. This is not a Sprint issue. It's logistics.

I actually would like to see smr left to only those too far from the tower to use pcs

I am starting to think that Sprint won't deploy LTE-Advanced until 2014 just because they have so much on their plate in 2013. I guess Sprint can have the opportunity to upgrade to LTE-Advanced if the tower crews have to go back to those NV completed sites to deploy the 800 MHz and 2.5 GHz LTE later on this year but who knows.

It's not like they will be the same people anyway. Just another contract. The planning, engineering and money are the big obstacles.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
