LTE Advanced and phones

Recommended Posts

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.

    • Another SCP beta is rolling out now, with some bugfixes as usual but also some fun new options to test: Non-standalone 5G-NR cells can now display Site Notes. This feature works in the same manner as how neighbor cell notes are displayed, requiring a PCI and your device's location. This option is enabled by default. As is the case with neighbor cell notes, you cannot edit NSA site notes directly unless there is an NCI being reported (which I have never seen); it uses the previously recorded standalone log entries. Like neighbor notes, if a cell has been previously logged but there is no note, you will see the distance information only.   Logging cells that are not reporting a valid PLMN is now possible. This option is disabled by default, but if you enable it along with two other options (log sites with missing GCI/NCI and to log sites with missing TAC), you should begin logging most NSA 5G-NR cells. A PCI is needed at a minimum, which is not always reported depending on your device and network factors. ("Sites" will be renamed to "cells" on the Preferences menu in the next update.)   Users can enable an option to display LTE cells above 5G-NR cells in the app if they choose to do so. This option is disabled by default. Should help improve the readability of your screen if you have NSA 5G-NR cells constantly appearing/disappearing. Please give these options a try and let me know if you notice any issues.. thanks!
    • Not yet. We probably won't see one submitted until construction on the new building is substantially complete. 
    • Yes, that is where the site used to be. All the antennas were removed. I hope they add a new site soon. Have any permits been submitted for a new site?
    • Looks like there's a slightly taller building going up next door to where the decommissioned site used to be. Taking a look at StreetView, T-Mobile likely decommissioned the site because the east facing sector would blocked by the new building. If I had to guess, T-Mobile has already agreed to move to the roof of the new building and is just waiting for it to be completed to install the site there. What they should've done is just rearrange the sectors in the meantime but it seems like T-Mobile just bit the bullet and decommed the tower in the short term. — — — — — A permit was issued for a Sprint conversion at 150 Prospect Park West, finally filling in what is T-Mobile's largest coverage gap in Park Slope. Verizon is collocated on that building and AT&T has placed small cells along Prospect Park West to fill in coverage there while T-Mobile struggled using two sites, one at Grand Army Plaza at the far north and another at Bartel Pritchard Square to the far south.  
    • Yep, you can see the site was taken down between Aug 2022 and Apr 2023.
