Hi Gents,
What’s the best method to do overspell test for a boundary country for 5G?
A way to get their cell IDs.

I’ve heard about Opencellid (.org). But I’ve never used. Maybe some expert here knows a more complete source…

Another great project to find BS Location by MCC, MNC, LAC and CellID was Cellfinder.
Unfortunaleyly, it also seems dead.

This another one seems “live”, but only for Europe and part of USA.
Interesting info is that it is under Creative Commons Attribution-ShareAlike 3.0 Unported / ODbL licence © 2020.
Also, You can download data in the format of SQLite, a database engine. You can use a GUI like sqlitebrowser or anything like that to view the database contents (sqlitebrowser DOT org). But the best way to read it is using Python or R (with the package RSQLite).

This is certainly a very important point for all RF Engineers and other technology professional, mainly with 5G deplayoment rollouts accelerating (more towers, more cells).
I don’t know the “best” way to find cell towers/cellid in any region, but here are some summary:
Using cell locators
Like those informed above (i’m adding to the list), but also other:
- OpenCellid - seems nice, but also seems not active anymore.

CellidFinder: Another great project to find BS Location by MCC, MNC, LAC and CellID was Cellfinder.

- CellMapper nice, but only for US.
A nice cell tower map locator option, but unfortunately most samples for US only. Filter help to select service provider and enter address or zip code to see the closest cell towers.
-
Scadacore: nice, but only for US.
This site shows you an overview of all the cell towers in the US and the data is sourced from the FCC website. Just zoom in on the map to where you are located to see the nearest tower.
-
CellReception: another option for US data
All cell phone towers registered with the FCC.
- AntennaSearch: powerful, but US only. Also, design outdated.
For advanced users to have access to a comprehensive list of every cell phone tower within a three-mile radius of your location using this site begins with entering a street address into the site’s search engine. Plotted on Google Maps, exact addresses are given for registered cell towers—along with details on the tower.
Smartphone Apps
Also a quick resource for locating cell phone towers/cellid are apps.
No matter what you’re looking for in a cell tower locator app, chances are the App Store or Google Play has one that fits your needs.
There are a lot (really a lot) of apps, so just listing a few:
-
OpenSignal - the preferred (most downloaded) for iPhones & Androids
It’s an app available for iPhone and Android, and it has coverage maps for all major networks based on data crowdsourced from millions of users. The app helps you see 2G, 3G, 4G and 5G network availability (along with stats and speeds experienced on networks worldwide) to help accurately measure the everyday experience you can expect on your cellular device.
-
Tutela - similar to OpenSignal, another app for crowdsourcing
The Network Assessment Tool (NAT) application is designed to record and transmit anonymized network performance data for analysis by the Tutela Analytic Engine. This data is used for the purpose of assessing network quality of service issues. No personally identifiable information is recorded or transmitted, including no key press information, no contact information, etc.
-
Network Cell Info Lite - one of the best, according to Android users (rate)
Exclusive to Android users but is one of the most highly-rated cell tower locater apps in Google Play. This app shows you cell tower locations based on their database so you can easily track signal strength in a specific area. This app can monitor wifi and cell signal in real-time and can show you maps with network cellular info and signal-meter gauges.
-
Cell Tower Locator - also a good app, but only for Android
Allows users to get the approximate position of cell phone towers within a stored database. The app’s interface provides cell IDs, signal strength, and GPS location. According to the developers of Cell Tower Locator, the precision of the estimated cell position is better for sites with three cells detected. If only one cell is visible it’s likely a cell serving area, not a position.
-
Cellular Network Signal Finder - the top Rated for iPhones
Simply download this app and allow it to use your current location to find the cell towers in your area. Refresh the map to see even more cell phone towers next to you. One downside of this app is that you can’t filter by your preferred service provider.
-
LTE Speed Coverage Map - also a good app, but only for iPhones
If you’re curious about how fast your cell phone connection is where you live, work, or visit, anywhere in the U.S., check out the LTE Speed Coverage Map app. This handy tool lets you view the average download and upload speed for each of the four major wireless carriers. The app also provides the average ping (or response time in milliseconds) between your mobile device and surrounding cell towers within a radius of two miles up to 90 miles.
That’s it…
The list is very big, but above you can find some of the best options.
If you know some app or website that help to find cellids/towers information, please share.

Not sure if we can get cell id of other networks without having neighbor info report.
Generally other network/vendor neighbours created with exe definition.
This info mostly needed for border area sites between 2 country to avoid cell coverage in other area.
It should be in SIB1 but since SIB is not broadcasted in NSA don’t know how we can get it.
Sme guys managed to get it.
In NSGuru it is displayed on the UE screen.
HI Guys what is the best free app for android to measure RF performances of the 4G/5G networks?
Nsguru but it is not free. Is like 50 USD per month.
I want to inform everyone that Cellmap is now available to much more countries, including Europe.
You can check locations of all Towers, Frequencies, PCIs and Signal level.
It is worth to give it a try here:
Where data is colected from?
Is it an android App?
Yes, it has a huge community that contributes to it.
Information is accurate but not the latest one.
Still good to check tower locations, PCIs, eARFCNs etc.
Cellmapper on Android with over 500K downloads till now:
Is it crowdsourcing?
Yes. For the cell mapper click on one eNodeB.
It will give you footprint of each of its cells.
It is amazing!
I mean it looks like this, the maximum distance each cell is serving:
How does it know site location? And also Azimuth?
What are the steps to get this?
In the map, click any eNodeB like this:
And then cells will open, if there are measurements there.
If don’t, there will be no cells opening.
You can even see overshooting cells:
The location data is based on account contribution:
Members can delete or change long, lat of sites
Site, cell id, frequency… I think is load automatically by tool.
