Backhaul & ping


Recommended Posts

Sprint lte seems to have a slightly higher ping than all the other carriers could this be a result of backhaul, or could it be a result of something can someone explain?

It might be something in your area with traffic routing. In Syracuse, Sprint has better ping times than AT&T or Verizon. Usually 20-50 ms on Sprint vs 50-100 ms on the others.

I normally may get 90 ms on B26. Around the same on B25 too.

i usually get around 100 on LTE while using sprint.  But it really doesnt make much a difference.  But I have been averaging about 150 to 210ms on Clear sites.

Ping is highly variable on all providers. It depends on the air link saturation, backhaul type, backhaul burden, LTE data core burden and LTE data core connection to the internet. As well as changes in dynamic routing.

 

In some places and in some scenarios, Sprint will be highest and Sprint will be lowest. No one can say Sprint has the worst ping of all providers, but you may be able to say in your observances that Sprint has the highest pings that you've seen.

 

If Sprint is the worst now, that can easily change. Because Sprint uses dynaming routing and dynamic LTE core load balancing. Your sites may be connecting to a more distant LTE core for a time, because the default core for your sites may be undergoing work. We see this all the time. And it will continue until NV upgrades at switches and cores are complete.

Would backhaul have any effect on outgoing calls being delayed. This seems to happen when I'm connected to lte.

Backhaul? Not likely.

is this a normal problem that will continue, or something that can and will be corrected?

Will you provide a link that explains "e/CSFB effects"

It's a normal problem, but will go away when VoLTE happens. e/CSFB is the way tri-band phones currently make calls. Tri-band phones only have 1 antenna, while single band phones had 2. Single band phones are always connected to 1x/EVDO and LTE at the same time. Tri-band phones are only connected to LTE or 1x/EVDO, never both at the same time. So, when you make a call while on LTE, your tri-band phone has to disconnect from LTE and connect to 1x/EVDO. This sometimes takes a few extra seconds.

 

But remember, this will no longer be an issue when VoLTE is activated. :)

5 to 10 seconds isn't a problem, but often I run into anything between 20 and 30 seconds. This happens on 2 different sites that I've found.

Believe it or not, people still make phone calls, and if you have one tower serving a ton of people, the voice carriers can get loaded up making your outbound calls take a little longer to connect.

As a owner of a business, I use 3000 plus minutes per month.

That is esfb issue. It has happened to me so annoying just looking at my nexus 5 says calling for like 15 seconds.  Miss incoming calls also.  Call sprint itll be fixed soon.

    • Well, I saw a good deal on a factory unlocked A32 5G on eBay and was able to convince the seller to show me the software info screen--and it was May.  So I jumped on it. Stuck one of my Tello SIMs in it, and while my Moto One 5G Ace would connect to n71 SA, this phone refuses to do so.  And with only 0 for the TA value, it's less useful for LTE than my older devices.  Oh, and the *#2263# menu doesn't work properly for NR.  So definitely glad I'm able to disable updates. - Trip
    • NextWave re-emerges with 2.5 GHz private network service  https://www.fiercewireless.com/private-wireless/nextwave-re-emerges-25-ghz-private-network-service https://www.nextwave5g.com/nextwave-news The only way for T-Mobile to get up to 190MHz now is to either buy out NextWave in it's entirety or wait until NextWave's lease is up and attempt to "outbid" them for the right to lease the spectrum from the Archdiocese.

    • Mike. I sent in more diags for wi-fi 6e yesterday where SCP shows channel = 0.  Thanks.
    • Added and modified them all! I took a trip through the L train tunnel between 1st Avenue and Bedford Avenue recently and found n41 live in the tunnel. It's 80 MHz, speeds were 250-300, and I didn't have time to check if n71 is there. Some stations speeds slow wayyyy down when a train pulls in now, even the ones with B2 at 15 or 20 MHz, so any upgrade is great sight to see.
