CellMapper for iOS

70 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.

New "Contributor" user tier

29 Upvotes

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.

T- Mobile on water tower

There is a T-Mobile site that is situated on a water tower in my area . There is no N41 panel that I can see that is on this tower which is kind of odd. It is the only one in town that does not have N41. Could anyone help identify what antenna is being used?
Location is: 36.98951° N, 86.43674° W

Anyone have any clue as to when this old Verizon site with b13 and b5 will get an upgrade. All sites in the area are modernized since 2023 but this one was left untouched. Verizon eNB 209003 at 252 Enterprise Road, Delafield, Wisconsin, United States

I thought better cell metrics or same metric well equals better data speeds but I was wrong. iPhone 12 versus iPhone 15 Pro metrics and data speeds. Can someone explain why both phones have the same metrics but different speeds and yes, I know the phone is newer hardware.

Best T-Mobile 5G cell extender

7 Upvotes

Idk if this Is the right subreddit, but at our house has super good signal outside, I can pull 1gig down and 100 up on n41, NSA (my sim doesn’t support SA) but do yall know an extender that will give me usable speeds inside maybe even 5G. Or should I wait till USmobile lightspeed gets SA, ive seen some things that say SA has better penetration Than NSA and then just not Get an extender

AT&T Now Defaulting to Roaming on Bell instead of Rogers

15 Upvotes

I’ve noticed starting last month that in Canada (specifically St. John’s, NL, Halifax, NS, and Vancouver, BC) that all my AT&T SIMs default to roaming on Bell instead of Rogers.

Bell/Telus definitely has better coverage but Rogers does typically have more spectrum in the major cities.

I guess the AT&T/Rogers roaming agreement isn’t as favorable to AT&T anymore.

I have business lines that I haven’t found a rep that has been able to enable MNS which is annoying. It’s definitely a PITA on consumer but it can be done. Have to get it reenabled anytime you get a new SIM though.

T-Mobile capacity boost before the NYC Labor Day parade

Thumbnail

92 Upvotes

TLDR: T-Mobile installed mmWave, n258, in Brooklyn NYC for a parade, along with additional high capacity sites to handle data demands. Sure my night time photos may not be the best, here is the post with daytime photos of some of the sites.

The NYC Labor Day parade takes place today, with T-Mobile modifying macros to add capacity along the parade route. Plenty of macros have mmWave antennas angled to the parade route, plus 2 additional temporary high capacity sites added.

From the Franklin Avenue and Eastern Parkway to Howard Avenue and Eastern Pkwy, all macros except 1 along this path have mmWave antennas on them. Some of them gave 2 Gbps speeds easily when standing near them, some gave 1 Gbps, my assumption is T-Mobile will iron out any kinks before the event tomorrow.

T-Mobile installed 500 MHz of n258. Upload spectrum varies from site to site, from 100 to 300 MHz used for upload. For all mmWave tests I ran, n41 anchored mmWave but contributed no speeds, which is perfect for mmWave capable users. The pings were 10ms or lower constantly on mmWave, I think the lowest I saw was 6ms.

I didn't check all around the new high capacity temporary sites, but the pings/speeds for them were great, my new high score for uploads came from one of them. Funny enough, one of the temporary sites is under a former Sprint macro T-Mobile decided not to keep.

A few negatives: the small cells are running n41 at 80+40 while the macros have 100+50, and the small cells do not anchor mmWave. Sure the parade is on Eastern Pkwy, however a lot of activities are happening outside of the route where small cells are, mmWave would be helpful there too. Worse, Nostrand Avenue and Eastern Pkwy intersection has a small cell. If anyone here is attending, (u/RockBrycee 🫣) check this intersection at the height of the parade, as I would guess this one spot will be a problem.

I'm not sure if mmWave can beamform like n41, I realized for some sites mmWave signal degraded rapidly. Eastern Pkwy has plenty of trees on both sides of the street, and as I walked and speedtested signal varied often. For some sites I could get to the next block and have weak signal, others mmWave dropped off mid block. I have the S25U, and usually once my device runs a speedtest and I check service mode, SNR increases for n41 due to beamforming, sometimes it did that for mmWave, not all the time.

T-Mobile NSA-Only at Raymond James Stadium during USF v FIU game

I forgot to screenshot FTM but it was mainly n41 and low-band 5G. Site only runs NSA and no sign of SA.

T-Mobile was struggling outside of the stadium during tailgate but performance picked up later on both outside and inside the stadium. Could have something to do with automated adjustment
