LTE Plus / Enhanced LTE (was "Sprint Spark" - Official Name for the Tri-Band Network)


Recommended Posts

I guess I should also throw in the Note 3 signal bars also show LTE strength.

I noticed this myself. I think that's great. Next I wish they could implement the status bar to differ between 1X and 3G. I understand 1X is a 3G technology but it's nice to know the difference. I find myself checking signal check a lot when I feel as though my data is slow. Most of the time it's because I'm not really connected to "3G" but 1X.

I've read through the last 4-5 pages, and don't see this addressed.  I have 3 things/questions/comments: 

 

#1. It appears that the 4.3 update for the S4 does not show equivalent signal bars to LTE strength, IF one can believe the Signal Check depiction of bar strength, which I'm pretty sure is close to how OS determines the signal. 

 

#2. I notice that if I have strong LTE outside (-80-85dBm) and go into a building, I'll lose the LTE and pick up eHRPD quite strongly (-55dBm). Since I have a S4, I'll only get the band 25 1900LTE and the eHRPD broadcasting is also off the 1900 band.  Are the radios just that much stronger for the 3G than the LTE? Will this eventually give me 1900LTE inside the building equivalent to the 3G that I'm seeing? 

 

#3. I also see that if I drive around the city with the LTE Engineering mode on, it'll report that I'm always connected to LTE just very low at -117dBm.  At this point, the phone/signalcheck report that I'm getting 3G because that signal is stronger and it bumps to that for data connectivity. 

 

SO, will 1900LTE be equivalent to eHRPD 1900 as far as signal and connection?  Or are the LTE radios just weaker?  Will they be "turning up" the strength of signal on towers as a market matures?  Or it is what it is and the LTE will not be any better on 1900 than it is when they first turn on the tower?  Perhaps I assumed that I'd at least be getting LTE where I had 3G before, inside or out.  

 

Feel free to link me to an article that discusses this, I couldn't really find one that discussed this explicitly. 

 

It's all relative. SignalCheck may see -100dbm on LTE as 2-3 bars of LTE and Sprint may see that as 1 bar.

Already posted in the G2 users thread, but we'll put it here too.

 

 

Did Sprint finally go out and find their answer to Neville Ray? Or is this someone SoftBank wanted Sprint to hire sent in by Masayoshi Son?

If you manually do, or sprint initiates an update profile operation, it always updates the band priorities.

 

I mentioned this the first week or so of having the nexus 5, that the nexus 5 'spark update' may be nothing more than a network pushed profile update to enable the bands and set the priorities without the user having to manually enable them.

 

We have had at least 2 confirmed band 41 connections on nexus 5, so there does not seem to be any device problem connecting, but appears to based on the tower and/or network acceptance of the n5 connection.

What configuration was this in? They said 60 MHz, but what MIMO, what modulation, etc.?

I'm assuming 60 MHz TDD to 1.3 Gbps would involve 8x8 MIMO and both downstream and upstream OFDMA.

I bet Sprint will market this as 5G and it'll be available likely 2016.

It won't be on any smartphones for a long time.

 

Manufacturers are still trying to figure out how to place a 4x4 LTE antenna on a phone and not incur a size and weight penalty. LTE Advanced like this will be in dongles first. I wish NSN would sell that dongle for Sprint though, that would be epic.

In the video, NSN's Eric Ortiz mentions that NSN and Sprint are using 2.6 GHz spectrum, aka band 41, configuration 2 of TD-LTE (which is 80% down/ 20% up), and LTE advanced features. Forward to :47 of the video.

Right. I guess I should look up what configuration 2 is. Once I know what they're using I can determine how likely that is and pressure my vendors of its likely.

Can't wait!! I think they are launching/deploying 20 x2 (40 mhz) sometime next summer and from a video I saw it can do over 100 mbps. Hopefully the 2014 line up of triband phones will support that

So laptopmag had a review of the Samsung Galaxy Mega testing sprink spark in NYC and came across some interesting numbers actual comparison between the HTC One Max, and the Galaxy Note 3 single band performance...http://www.laptopmag.com/reviews/smartphones/samsung-galaxy-mega-sprint.aspx

Well, at least everyone knows Spark is worth it!

    • I've now seen how things work in Kobe, Hiroshima, and Osaka, as well as some areas south of Osaka (e.g. Wakayama, Kinokawa), and tried three more SIMs. The two physical SIMs (different branding for each) both use IIJ, which provides a Japanese IP address/routing on NTT, aleit LTE-only, so latency is ~45ms to Tokyo. The catch with NTT is that it uses two frequency bands (B42/3500 MHz LTE, n79/4900 MHz NR) that you're not going to get on an Android sold in the US, and I'm guessing that B42 would be helpful speed-wise on that network, as it doesn't have B41. I also found one place that doesn't have cell service: a vending machine in the back of the Osaka Castle tower. Or, rather, the B8/18/19 signal is weak enough there to be unusable. Going back to 5G for a moment, I saw a fair amount of Softbank n257 in Hiroshima, as well as in some train stations between Osaka and Kobe. 4x100 MHz bandwidth, anchored by B1/3/8, with speeds sometimes exceeding 400 Mbps on the US Mobile roaming eSIM. Not quite the speeds I've seen on mmW in the States, but I've probably been on mmW for more time over the past few days than I have in the US over the past year, so I'll take it. My fastest speed test was actually on SoftBank n77 though, with 100 MHz of that plus 10x10 B8 hitting ~700 Mbps down and ~80 Mbps up with ~100ms latency...on the roaming eSIM...on the 4th floor of the hotel near Shin-Kobe station. Guessing B8 was a DAS or small cell based on signal levels, and the n77 might have been (or was just a less-used sector of the site serving the train station). I'm now 99% sure that all three providers are running DSS on band 28, and I've seen 10x10 on similar frequencies from both NTT and SoftBank IIRC, on both LTE and 5G. I also picked up one more eSIM: my1010, which is different from 1010/csl used by US Mobile's eSIM unfortunately, as it's LTE-only. On the bright side, it's cheap (10GB/7 days is like $11, and 20GB for the same period would be around $15), and can use both KDDI and SoftBank LTE. It also egresses from Taiwan (Chunghwa Telecom), though latency isn't really any better than the Singapore based eSIMs. Tomorrow will include the most rural part of our journey, so we'll see how networks hold up there, and from tomorrow night on we'll be in Tokyo, so any further reports after that will be Tokyo-centric.
    • I think the push for them is adding US Mobile as a MVNO with a priority data plan.  Ultimately, making people more aware of priority would allow them (and other carriers) to differentiate themselves from MVNOs like Consumer Cellular that advertise the same coverage. n77 has dramatically reduced the need for priority service at Verizon where the mere functioning of your phone was in jeopardy a couple of years ago if you had a low priority plan like Red Pocket. Only have heard of problems with T-Mobile in parts of Los Angeles. AT&T fell in between. All had issues at large concerts and festivals, or sporting events if your carrier has no on-site rights. Edit: Dishes native 5g network has different issues: not enough sites, limited bandwidth. Higher priority would help a few. Truth is they can push phones to AT&T or T-Mobile.
    • Tracfone AT&T sims went from QCI 8 to 9 as well a couple years ago. I'm pretty neutral towards AT&T's turbo feature here, the only bad taste left was for those who had unadvertised QCI 7 a couple months ago moved down to 8. In my eyes it would have been a lot better for AT&T to include turbo in those Premium/Elite plans for free to keep them at QCI 7, while also introducing this turbo add on option for any other plans or devices. As it stands now only a handful of plans can add it, and only if you're using a device on a random list of devices AT&T considers to be 5G smartphones.
