Sprint TD-LTE 2500/2600mhz Discussion


Recommended Posts

Can LTE Broadcast be used for Netflix and other streaming content? Or even Slingplayer? I use both program fairly often

 

It might be possible for the highly in demand shows on Netflix, but there are way too many shows and movies on there to do it for all of them.

 Easy to miss. Nothing was put on the main page about it.

 

Yes, The Wall has become neglected.  After a year and a half of writing for all of you, Robert and I both have developed severe cases of carpal tunnel syndrome.  In fact, I now have to create my posts in The Forums the "Stephen Hawking way."

Is that because of carpal tunnel syndrome, or because it's really hard to type while wearing your straitjacket?  And then from a slightly different thread, there's the question of whether 2500 LTE is actually usable inside a room with rubber walls?  :lol:

 

(Sorry, I just couldn't resist!)

Rubber is wonderful for rf propagation. Low conductivity.

Na the wall is great, and I do appreciate all the hard work that goes into the articles. I just think when something fairly big like the change  in plans to add 2600 everywhere a little note there would be nice. Doesn't happen very often and a single sentence could pass on the news. Something like "In a conference call Sprint confirmed 2500/2600 will be added to most all NV sites, you can read all about it in the 2500 thread here...." A down side would be knocking the excellent PRL article down and that might get missed.

 

My opinion is just that an opinion. I don't know how much work it takes to do a wall entry. I don't know if there is a plan for what the wall should be for and what is not wall worthy etc.  

 

The funny thing is I always pictured AJ soundling like Steven Hawking  anyway. :P <joking>

Off topic not all rubber is the same, some have a lot of carbon and heat up in a microwave.

My apologies if this has been discussed already, but as this thread is nearing a thousand posts, I haven't been able to review each and every one of them. Anyway, I was doing a little reading on LTE Broadcast and from this layman's point of view, it seems pretty interesting.

Two Network Vision vendors, Ericsson and Alcatel-Lucent, are working with Qualcomm to develop the technology. Verizon has shown the most interest of any US carrier. However, I think that this technology is now tailor made for Sprint's forthcoming TD-LTE network given their Clearwire purchase. With their tremendous spectrum depth and cell site density, now that they've announced that they're going to put 2.5GHz on all ~39K and beyond, Sprint has a great opportunity to offer differentiating services depending on how the technology develops. It'll be interesting to see if Sprint pursues this and who they might partner with.

I think sprint should partner with Dish on this.????

So I can pick up band 41 LTE in Orange County with my MiFi 500.  :tu: Euclid and W. Broadway in Anaheim. I didn't detect any in Fountain Valley by the Fry's, which is definitely in the Clear WiMAX coverage area. They may have concentrated more on LA and north OC for their initial rollout.

I realized after making the above post that the MiFi was probably preferring band 25 over 41, so it's possible 2600 is on more towers than I found through my very brief visit to OC/LA. I'll have to get my MSL sometime and see if I can change the preference order.

In my triband tests, speeds did go down when you went inside if you were more than 1/2 mile from the site. However, even with one bar, I still was getting 7-20Mbps on TD-LTE 2600. I even hit 18Mbps with a -120dBm RSRP signal in one test. Also note that my best speed test of all was taken inside my hotel room.In Thornton, Colorado I did testing of where TD-LTE 2600 overlapped Sprint LTE 1900 and the TD-LTE had better results in most instances. Only when the Band 25 exceeded a -80dBm signal and the Band 41 was worse than -115dBm did it get better to be on LTE 1900 Band 25.Robert via Samsung Galaxy Note 8.0 using Tapatalk

I know there's no definitive answer to this question, but I live about 2.75 miles from the nearest tower. Can I expect to pick up LTE on 2.5 ghz? I get a decent 3G signal being this far away (usually between -80 and -85).

I picked up Band 41 in Queens over the weekend :D Didn't get a chance to run some speedtests, but there is active coverage there. I used the MSL on my Zing to change my priority to 41, 25, 26.

Now I know why we aren't discovering 800 lte coverage.

 

I wish you all would set the priority to 26, 41, 25. So you see SMR first then BRS then PCS.

I dunno, I'd prefer that my devices keep off 800 unless they absolutely need to since there's way more spectrum in the higher bands.

And your age!

 

Ummm, I definitely was not born in 1996.  Nor did I graduate in 1996.  But it does show the year I was married.  ;)

Not to mention 2600 has better performance.  I was getting 10-20Mbps on TD-LTE 2600 sometimes even with zero bars.  Signal quality was everything on TDD-LTE.

    • 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.
