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


Recommended Posts

Connected to Band 41 tonight with my Nexus 5 and well.....I'll just let the pictures do the talking

 

Edit: The pics were a little too big lol

Cant wait to see the pic, just kinda odd that Cali is the only place the N5 has connected to any B41 as far as I can tell...

Honestly I know this is off topic but I was reading this article about Verizon tripling its Speeds in major cities and I really think it's pointless. I feel like it's pointless for Carriers like Verizon & AT&T to have LTE because all they're gonna do is cap & throttle data & depending on how much data you have (2GB-50GB ) it's pointless and a waste a money. Then the prices for these low GB plans is ridiculous. More money thats just being wasted.

 

I have the original unlimited family plan with 4 people on it. I went to the Verizon website to check how much it'd be if my whole family were to switch & its almost double for some low amount of Data. Please let me know im how my family & I are supposed to split 6GB 4 ways -_-. I just don't see the point.

 

The only thing Verizon/AT&T are good for is competition & motivation for other carriers to be better & surpass them. Betchu if Verizon/AT&T didn't exist then we probably wouldn't have had LTE until 2020. Lol im being dramatic but you guys get the point.

They are increasing capacity because 4G has slowed to a crawl in many places, even if you have a cap what is the point of 4G if you are limited to 3G speeds.  Also remember there are people that still have unlimited on both AT&T & VZW.  All of our business devices even new activation's are unlimited data on VZW.

I found the TDLTE upload to be greatly affected by signal strength with signal strength weaker than -113db my upload would be lucky to break 2mbps where the download can be greater than 20mbps

 

in the -90db range I can crack 10mbps

 

1 test in the -80db range I was getting 15mbps upload

 

This was on the HTC one max (reception not as good as the G2/N5 i think) and downtown chicago

No, that much lower uplink performance really has nothing to do with TD-LTE signal strength.  By its nature, FDD operation has a fixed throughput ratio between downlink and uplink of about 4:1.  TDD operation, on the other hand, has variable throughput ratios between downlink and uplink.  The configuration that Clearwire is using should result in a ratio of roughly 8:1.  And your observed performance is around that range.

Interesting. I think I read that the down/up time ratio was 3/2 or something like that. I assumed that would mean that up load speed could hit 2/3 of down load. I also wondered why FDD was so much faster on the down load than the up load when both have a 5 Mhz carrier.  Must be some interesting things going on with different modulation schemes of the low power phones transmissions and the high power cell sites to have about the same range. Faster needs more power to get the S/N up to a usable level so it makes sense.

Yeah, you are not taking into account both MIMO and higher order modulations schemes on the downlink.

but down the street where the signal was stronger I was getting 40 down 15 up...? would that mean my 40 down is in fact due to backhaul capacity and if given enough back haul i could have gotten 15 x 8.... ~120mbps up?

Yes and no.  Backhaul is probably a limiting factor.  But you also have the HTC One max, which sticks with an older Cat 3 baseband.  It cannot exceed 100 Mbps on the downlink.  The handsets with the newer Cat 4 baseband can do 150 Mbps.

What handset is that?

That has a Cat 4 baseband? Any handset utilizing the MSM8974.

Can that change with an update/baseband update or the phones hardware?

Hardware. It is basically akin to a dual core vs a quad core processor.

In most areas, Verizon is significantly faster and they have better coverage more places. Also, the majority of people are going to use less than 1.5 gigabytes.

As I have observed, with a faster more reliable connection data usage goes up. Since Tulsa got LTE for most of the area, I've seen each of my family members data use roughly triple. My brother now uses around 9 gigs a month where he used to use 2-3. My dad's usage has skyrocketed from 300mb or less to 4-5 gigs (probably because he now trusts that streaming will work).

    • Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.
    • Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.
    • Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
    • At some point over the weekend, T-Mobile bumped the Omaha metro from 100+40 to 100+90 of n41! That's a pretty large increase from what we had just a few weeks ago when we were sitting at 80+40Mhz. Out of curiosity, tested a site on my way to work and pulled 1.4Gpbs. That's the fastest I've ever gotten on T-Mobile! For those that know Omaha, this was on Dodge street in Midtown so not exactly a quiet area!
