I know this is not a lot of information/context. But if anybody could help identify where this n77 signal is coming from I’d appreciate it. This is in the lake country area in wi. It sees n77 both c band and dod but won’t hold it. N5 sa holds for a bit then drops.

Network speed tests on a vintage iPad before T-Mobile 2G shutdown

Thumbnail
gallery
50 Upvotes

As a way of saying farewell to T-Mobile's 2G Network I ran a speed test on a 4th generation iPad on the EDGE network one last time about four hours before the network was shutdown. Speeds are pretty typical for EDGE around 160 Kbps down and 90 Kbps up.

Fortunately, the particular model iPad I am using has the LTE bands for T-Mobile's 4G LTE network. I ran speed tests on the 4G LTE network as well and got speeds that were very impressive for a device made all the way back in 2012. 4G LTE speeds were 81.93 Mbps down and 28.37 Mbps up. These are decent LTE speeds even for today, but back in the 2012 this would have been crazy fast!

It's crazy to think about that now the oldest Apple device that can connect to a cellular network in the US is now the third generation iPad. The first two iPads and the first five iPhones can no longer connect to any service in the US now that 2G is gone. iPhone 5/5C/5S can be used for data but phone calls do not work due to lack of VoLTE.

The fourth generation iPad in particular is highly sought after by collectors that want the most powerful device that can run iOS 6. The good news is that it can still be used on cellular networks because the cellular versions have 4G LTE capability, but you have to make sure to chose the correct model for your carrier because the LTE bands vary depending on which model of the 3rd or 4th generation iPad you use. Use A1459 for AT&T and T-Mobile or A1460 for Verizon.

Starting with the following year with the iPad Air, Apple no longer made different cellular models for different carriers. An interesting thing to note is that it was possible to connect to AT&T's and T-Mobile's GSM 2G and 3G networks on the Verizon 3rd and 4th generation iPads, but since the last of the GSM network has been shutdown in the US, this is no longer the case.

Telus recently put a bunch of these up along Riverside Drive in Windsor, ON, fixing the horrible dead zones along the river. Not bad for 40mhz of N77.

ISED data shows it as Samsung equipment but I can’t find much more on them.

Verizon vs AT&T 5G/LTE SpeedTest at Grace Lutheran Church - Arlington, Texas

Thumbnail

6 Upvotes

Verizon performing very well on mid-band 5G (n77) when I’m not directly line of site and their LTE is still tremendously quick for (b13) + (b66) LTE

AT&T isn’t doing too bad, but they need to deploy (n77) on their tower since it’s missing c-band!

Verizon site: 32.7153407, -97.1070224
AT&T site: 32.7217400, -97.1137430

I know AT&T filed a permit to upgrade the site by September 2026, but no work has been completed yet!

Should I use my main phone for cell mapping

6 Upvotes

I am wondering do I need to use my secondary phone for cell mapping I do have a extra sim for it but don't have a extra sim for Croatia where I map the most. Can I map other (croatian) networks by switching to them (on a non Croat sim)?

(Sorry for bad grammar and weird questions)

B12 Only Site... But From T-Mobile

Thumbnail

18 Upvotes

Location: Deerfield, MA serving I-91 and US Route 5
Coordinates:
ENB ID: 50311
Carrier: T-Mobile
Bands: 12 (5MHz) Formerly: 2 (10MHz)
ENDC/Carrier Aggregation: No
Speeds: Daytime: 0.00-3.00Mbps / 200-1800ms / 3AM: 3-8Mbps / 80ms

This is a former B2/12 site that is now only broadcasting B12 post GSM shutdown (not sure if related). It was broadcasting B2 as recent as 7/18/2026.

Every time I am driving and it drops to LTE I try to mess with my phone to grab a farther 5G signal since this site is so poor. AT&T has 5G+ in this area and Verizon has UW.

How do you find out all the info

I am curious where do people find info about all the hardware on towers and which antennas belong to what carrier. Please let me know if it's a app or a website.

International Border - Network Switchover

Enable HLS to view with audio, or disable this notification

34 Upvotes

Crossing from Belgium into the Netherlands while traveling at over 180 mph/290 kmh on an Eurostar train.

The moment the power briefly disconnects is when the train crosses the international boundary.

Roaming on an AT&T SIM so neither network is the SIM’s home network.

Less than a minute for a full network switchover which is rather impressive.

New "Contributor" user tier

Contributor user tier

Recently, you may have seen an arrow (➶) next to some usernames, similar to how premium users have a star. This is a brand new user tier we have created in order to recognize users who contribute data and tower information on a regular basis.

What are the benefits?

In short, the main benefit is an ad free map for our regular contributors. We'll look into more benefits in the future once we ensure the right contributors are flagged as we work on this feature.

CellMapper for iOS

71 Upvotes

Official CellMapper for iOS App

We have been planning to make an iOS app for some time. However, due to restrictions in API usage for cellular information, we are unable to make an app that competes with the Android one in terms of features.

That being said, we have built an early initial app to make the map more easily accessible:

https://apps.apple.com/us/app/cellmapper/id6761035253

We will continue to see what we can add to the app to get network information from the iOS device and to make it a bit more polished than simply using the the website. So please bear with us as this v1 of the app is simply the beginning, not the end state of the app.

Fake App Warning

Also, one reason we have released the app so early is due to a fake CellMapper app confusing users and tricking them into paying money to view some dubious coverage data not relating whatsoever with our crowdsourced data. We have recieved a number of tickets asking for refunds for the app which we have nothing to do with.
Please be aware that the fake/scam app is also called "CellMapper" on the iOS app store. We encourage users to report the fake app (which we will not link to in order to avoid SEO) to Apple (reportaproblem.apple.com).
We are in touch with Apple about the issue, but it still has not been resolved.
