So I average ~250-300MB of tethering monthly, mostly SSH and email traffic when I'm away from my desk. For me, deprioritization should not affect my shell sessions, and if it does, then that becomes an issue, but in my use case, its a non-issue to me personally.

 

Depends on how they implement deprioritization. I heard the way Sprint does it when you surpass 23GB is that they basically add latency to every packet on congested sites (ie make you wait because you're lower priority). In other words, increased ping times which would be awful for SSH.

Depends on where.

 

I'm in NYC and camping right now on a -101dB B41 site.

Likewise. At my place in Pittsburgh I'm at -95 on B41 and I'm about 1.5+ miles from the site. It is line of sight though... Pittsburgh geography helps a lot, sites are placed at the tops of the hills so B41 coverage is really good in the city.

 

On the other hand, B41 doesn't get very far at all in SF. I'm guessing because of site locations and building materials.

I'm sure you'll disagree, but at home you shouldn't be relying on 2.5 at home for internet service.

No of course not, but it's nice to have when you're out of wifi range. And it's nice when visitors have good service at your house and don't need to ask for the wifi password. What's home to you is a friend's place to someone else, if that makes sense. Residential areas should have B41.

Huh my 6S got 54057. Ok a related note, has anyone figured out what the difference between the 55xxx and 54xxx PRLs are?

I think it's corporate versus regular. Corporate used to have evdo roaming and consumer didn't. Not sure what the actual difference is now.

Yup, just got 55057 on my Nexus 6P

I thought equipment was only certified for up to 10x10?

I think it is, but the hardware is capable of 15x15. They just need to submit it to the FCC for approval, then push out a software update.

It probably is vastly outperforming the competition. Sprint has more spectrum still in use on legacy than any other carrier so voice is going to be good most of the time.

Do they though? In a lot of markets (SF, Pittsburgh, Sacramento for starters) I believe they're down to a single 1x1900 carrier and a single 1x800 carrier. Then 2 EVDO carriers, but those don't matter for voice.

I wonder why they have not decommissioned the Nextel sites?

They may have. This is just a record the city had of sites as of yet date. Likely pulled from their permit database.

Wow - are there maps like these for other carriers?

San Francisco has a map with every RF antenna in the city. You can filter by carrier. https://fusiontables.google.com/DataSource?docid=1jgD0NwaO_dLNhIkjaANj_2fzV9WFwLDGgb8uM57x#map:id=3

 

Was last updated April 2015 though.

At least we do have access to Boingo Wifi for airports.

Not Nexus devices [emoji17] Google added support for Passpoint in 5.0 or 6.0, but since Sprint Connection Optimizer isn't installed apparently it can't use it as per the agreement Sprint and Boingo have.

My understanding is that you either have Global Roaming (this is the default option), or Open World. So if you deactivate Open World, your account automatically reverts to Global Roaming. Someone may want to fact-check me on this but that is my understanding after my last conversation with Sprint in regards to this.

As of yesterday, when I went to change a line to have Open World instead of Global Roaming, I was unable to remove Global Roaming first like I used to have to do. There was no remove link next to it. However, I was able to add Open World to the line without removing it. A customer service rep confirmed Open World was successfully added.

 

So perhaps Sprint has now made Global Roaming the new default and we won't have to go through the hoops to swap between them anymore.

You should get one of the $25 SDRs and see if you can pick up anything in that frequency. My issue was I didn't have a suitable antenna. I have a feeling you have access to one though [emoji39]

Actually! I just hooked it up to my phone and the stock antenna works fine for the waterfall. You can see where the B26 carrier in Pittsburgh starts (on the right). I'm guessing 1x is on the left, and the dip is the guard band.

 

I'll be in Youngstown on the weekend of October 1, I can check and see if there's anything there then.

I will mention too that I think we're going to have a B26 launch soon. On one of my devices, I've had B26 only scans running for the last few months. I've had numerous times where I've ended up on B25 since labor day weekend. Nothing has shown in my logs yet, but I suspect that a B26 test mode is active which I think would probably kick off any regular user.

About the second B25 carrier, from my understanding it does require a site visit to adjust CDMA carriers and relocate them for LTE.

I don't think this is true. It should be done remotely. Lots of drop down menus from what I understand, but batch scripts can be used to automate it.

Really??

Yup. Here's a screenshot of Global Roaming when I was in South Africa. It was throttled to the speed they said it would be, so I just got a local SIM.

 

The traffic is routed to Sprint first before going out to the internet. So you have a US IP address as well. But again, from far places, such as South Africa, it makes the latency unbearable. And kills your battery since the mobile radio is basically always active since the speed is throttled (ie it can't quickly finish up and go to sleep).

Do you see the 1st carrier and the 2nd carrier CA from the same site? For a time 3rd carrier did not have CA or at least people weren't seeing it. People would have to have CA turned off or be idle to see the 3rd carrier by itself. When a data session was started it would switch to 1st or 2nd carrier CA together.

Yup, here's one taken just now from the same site while running a speed test. First and second carriers aggregated.

I wonder as other carriers kill off their 2G networks, Sprint is getting access to those carriers 3G Network by default, hence the increase in speed. Another option is not all carriers bother to throttle roaming customers. Sprint really has very little control over the experience on other carrier's networks.

Sprint is the one doing the throttling, not the roaming carrier. All your data when roaming abroad is routed through a Sprint server in Kansas. That's how they track data usage as well as throttle it. It also means awful pings/latency when you're far from Kansas since everything has to go there first.

 

Also, the unlimited "2G" just means 2G speeds. It's often over an HSPA network, not GSM.

It is neat that it looks like it is in CA with the 2nd carrier. I don't think that is normal. I have only seen that at one tower in New Haven, Conn.

It can only be CA with the second carrier, since it needs to be contiguous. Last night I had the third carrier being the primary and the second carrier as the secondary.

 

 

Sent from my Nexus 6P

Yup third carrier is popping up all over Pittsburgh

Hope that extends to stations not shared by bart

Yeah I believe BART now has service in most stations and tunnels. The southern portion had it for a while, and last I checked downtown also has it now, albeit not B41. I think it's been extended to the East Bay now as well. Ashby Station has B26 (seemingly a DAS), but I couldn't find B25 oddly. It cut out halfway to the downtown Berkeley station. So they're definitely making progress on BART at least.

For what it's worth, I have been using this for about a month with great success. Charges quickly and efficiently.

Yup I have the same charger. Works great.

Heh. I'm still in high school. [emoji14]

 

No firsthand memory of 9/11 at all (thankfully).

Ironic, I was in high school when it happened. I remember watching it on TV during what was supposed to be geometry class. We heard the plane that crashed in PA fly directly over our school...

only when a CDMA shutdown happens. The 20mhz on the A block can be used to do 10X10. Right now 10mhz of it is being used for CDMA. The G Block cant be used on CDMA.

I'm not sure which post you're replying to, but yeah there will only be 2 5x5 B25 carriers until the CDMA shutdown. There's no room to expand further, and no way to make a 10x10 until then. Of course, this means no EVDO, but there would be a single 1x800 carrier.

 

In other words, it's years away from being a possibility.

Is LTE 800 deployed in the SF Bay area (especially South SF near SFO)? Heading up to SF in the next 2 weeks and would like to know.

Yes there is B26 on pretty much every Sprint site in the bay area. SFO has a DAS that has both B25 and B26. Plus the airport is ringed in Clear B41 sites. Speeds at the airport are great.

 

Usually you don't want to be on B26 though, because it's always super congested and barely usable, if at all.

Anyone have Android N installed yet and is rooted? If so, I was wondering if you could check something for me before I upgrade.
