What's the range of the core? or is it wired?

 

There is no range for a core. Cores are set up and configured for markets based on customer counts. Cores can handle so much traffic. At some cores, they handle eHRPD and LTE traffic for several markets. And other busier markets, they may handle just one market or a portion of a market.

 

A site is connected to a core through backhaul.

It's normal that I haven't seen more than 3 bars of LTE coverage in a full 3G coverage area? I know the 'bars' aren't accurate in terms of LTE, but when I'm connected to LTE, bars drop.

 

iPhones do show LTE signal strength in bars, so what this means is when you are connecting to an LTE signal, you are connecting to a tower(s) that is a farther away than the towers that you receive 3G from. This will be common place until more towers are upgraded.

 

 

 

I noticed that when I am connected to the 4g tower by West Compton/North Carson, the speeds are just so slow they make 1X look fast. I wonder what is the cause of that.

 

LTE speeds are very signal strength dependent. So if you have a weak signal, you will experience slower speeds.

 

There have also been cases of towers being live, but only giving <3G speeds on the LTE signal. The only way to know which it is (signal strength or towers issue) is to look at the LTE engineering screen to see what your signal strength is.

I am a block from the upgraded LTE tower. I presume the signal strength is high. I understand Sprint is still in testing mode while more towers come online so I don't have to many complaints with the LTE speed. I just wish the upgraded 3G would start to roll out faster.

ay, I really hate to say it but I'm starting to notice the network struggling during the day.

 

About two months ago I was getting great pings and speeds during the day. Now I only see that type of performance late at night. Having said that, I am having a consistently better experience using data regardless of what a speed test says.

The LTE network cannot be struggling under load yet. However, there is a lot still going on. The network is still in an unlaunched state in the LA market.

I am right in front of a site that was giving almost 2mbps constantly and since a week or so its been like this.Do this mean that this site its under upgrade work?

 

No way to know for sure except to find the site and look at it.

thats the problem.on the map says it it in sears but i cant see it,unless its on the roof and there is this building in front of sears that is full of panels on the sides windows roof.the site might be there

I live in Canoga Park now and get LTE all over my area (except my street.. It dies there.. Lol). But is this phase the weak phase or will it always be this weak? When driving I never have LTE for more than a minute or two. It's very spotty, never reliable, and rarely more than one or two bars of voice signal at the time of reception.

Any word? Merci !

Service will continue to be spotty as the network build-out continues. It will be several months before all towers are completed. Once that happens, you should have LTE service nearly everywhere you have 3G service. When 800 LTE is launched later next year, your LTE service area will expand a bit more than what it will be when the current 1900 build-out is complete.

I'm not saying LTE is the issue but I am observing that the network on a NetworkVision'd site is performing poorly during the day compared to one month ago. The network also returns to the fantastic performance of one month ago late at night and early in the morning.

 

I'm aware the bottleneck might be at a core or something else. Whatever the problem is, I suspect it is not at the cell site. We'll see if it improves in the coming weeks and months....I hope it does.

3G only slows down, or LTE also?

I'll have to see about LTE (not picked up today) but 3G for sure. I'm looking at ping times more so than speed as I've noticed low ping times results in a better experience regardless of speeds....you can even see it with the speed tests as the connection remains very stable with a low ping while when you have higher latency you tend to have more peaks and valleys.

 

Right now on 3G I have a ping of about 285ms through my phone to the server. When I wrote my post at 6am I had a ping response of 85ms through 3G. Since last month, something has changed that is now causing an additional delay of 200ms.

 

What could it be?

I think this is spread all over LA even less than a block from the tower with clear view the speeds dont reach 10mbps anymore and also 3G even close the site is slow compared with a month ago.

3G I am less concerned about. The reason being, in an urban area, there is no way for certain to know which 3G EVDO site you are connected to. Your device will always be in range of 3-4 (maybe more) EVDO sites and your device/network will pick which one for you to connect to based on EC/IO ratio. It doesn't care which one is faster or upgraded.

 

So until all your 3G sites in your vicinity are upgraded, you can be on a legacy site and have no idea (even when standing next to an upgraded site). Also, another problem is in an area with lots of legacy sites, but few NV sites, the NV site(s) can be temporarily overrun with traffic shunted from the adjacent overburdened legacy sites. So as more legacy sites in the vicinity are converted, the less burden on the original new NV site becomes and traffic more normalizes.

 

Although having adjacent NV sites helps a lot, full relief will not occur until more sites are converted, since we have no ability to control which sites we connect to.

 

Also, one last possibility, on a 3G only upgraded site, it is possible that the new backhaul is not active yet. If the site is marked 3G/4G complete, then we know that the backhaul is ready, because they cannot run LTE on legacy backhaul. On a 3G only upgraded NV site without new backhaul live, you will definitely experience evening performance fade.

 

All of these scenarios are plausible in your circumstances.

    • 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.
