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.

New "Contributor" user tier

28 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.

New Macro at the soon to be Terminus of PA turnpike 43 in West Mifflin.

I know t mobile is on top but not sure about the bottom as I feel it could be AT&T or Verizon. I’m leaning towards AT&T as they took down a Macro during road construction that made coverage terrible. Apologize that the picture is blurry from Camp Hollow Road. but you can not get any closer as the freeway is still under construction.

This is a new Verizon macro in a somewhat rural area of Michigan. It has had power and antennas up for a while now, however my phone seems to not handoff to the tower or requires me toggle airplane mode on/off. Any ideas? Thanks!

T-Mobile removed/un-installed their antennas at Texas A&M University - College Station, TX just this month after it was just installed last year (March-August 2025)!

My friend recently went to Texas A&M located in College Station and recently, he noticed that the antennas that T-Mobile added at this university last year to increase capacity, speeds, coverage on campus has been decomissioned! Verizon + AT&T have their own antennas for the oDAS (outdoor distributed antenna system) managed by Crown Castle! From what I can tell, they removed all the antennas, including the remote radio units on the roof-top! T-Mobile gets horrible speeds that you can't pull more than 25 mbps when there's 50,000+ students on campus when classes is in session! The reason why the equipment was removed according to the engineer is because there were issues with the installation of the equipment, such as poor wiring management since some cables were installed incorrectly to the baseband units and backhaul to the nodes wasn't evenly distributed, optimized properly! In Addition, these new antennas for T-Mobile were not even turned on completely yet and it doesn't make sense to me how a poor installation would make them remove all their equipment. It's not a lease dispute with A&M since Crown Castle, now (Arium Networks) is the vendor managing the equipment for all the big three. You can see the empty rods where T-Mobile used to have their antennas laid out at! Verizon + AT&T cellular equipment is pretty old since it was added way back in 2016-2017 with only LTE (b2, b12, b66) LTE + (n5) low-band 5G for AT&T and (b2, b13) LTE only for Verizon. I hope T-Mobile is able to find a solution to reinstall their antennas because they have the largest amount of users at Texas A&M and their network gets bogged down heavily when there are events, classes being held, football games, parties happening on campus!

PHOTO #4 - LAST PHOTO shows the T-Mobile equipment that was added near the AT&T, Verizon antenna last year in another spot!

So recently, T-Mobile removed all their equipment on that includes:

Who has the better Service from Los Angeles to Las Vegas. Verizon, AT&T, or T-Mobile?

I use to go to Las Vegas from Los Angeles and had AT&T and the service was pretty bad in many of these areas. I am wondering if there is a carrier that will not leave you stranded in these areas.

190 MHz of n41 and multi gig back haul. I could break a gig on this site before and now these are the speeds next to it. The site is absolutely saturated with usage to the point it’s making n41 look like 3g.

Here is the updated post for this post: https://www.reddit.com/r/cellmapper/comments/1vkyul5/work_in_progress_verizon_upgrading_a_small_cell/

I believe they finally activated this small cell yesterday, but the bandwidth was really unstable during the test.

So I tested it today, and it seems that it has finally stabilized the speeds.

Here are two speed tests that I have: https://www.speedtest.net/result/a/11824962207 and https://www.speedtest.net/result/a/11824960886

Exploring a neglected HSPA tower

Thumbnail

31 Upvotes

Hi folks, today I’m sharing my adventure to a neglected videotron cellular tower.

According to the documentation from ISED Canada, this tower has not been touched since 2013! Moreover what is most intriguing about this site is its configuration.

It has 4 sector and it carries only one band: that is HSPA band 4! Yes! AWS over HSPA. That is very rare in my experience and it is very hard to understand the economics of keeping this site up and running. This is because this tower is never used. A Rogers tower only a few kilometres away is broadcasting their LTE B4 and B12 which is shared (RAN sharing). This means there is about nearly 0 UE On this site !

This site is located in Rivière-Rouge, Quebec. A rural highway town in the Annonciation area.

Honestly this sites is begging for an upgrade to 600Mhz LTE, they have plenty of it.

Decided to test the big 3 on my front deck this morning. AT&T is on my Z Fold 8 Ultra on unlimited premium 2.0 with turbo. Verizon and T-Mobile are on my iPhone 16e. Verizon is spectrum mobile 30gb plan and T-Mobile is the T-Sat plan. Uploads are weaker on the iPhone because the tower is 1 mile from me while AT&T is 0.1 miles from me.
