How to get the location of the cell tower (base station) connected to my device

[Adeel]

Hi Dev team,

I have my Thingy91 deployed and running. I wanted to know how could I locate the base station that my device is connected to. I have the information of MCC, MNC, TAC, Cell ID. 

I wanted to know how if there is a way that I could use this information to get the location of the base station. 

Regards,

Adeel.

Hello Adeel, 

Do you mean the physical location of the base station? I dont' think this is possible. There is an AT command Neighboring cell measurement and report (AT%NCELLMEAS). This starts neighboring cell measurements and reports the channel parameters with a result notification when the measurements are finished.

Kind regards,
Øyvind

Hi Oyvind,

I wanted to have the feature that is present in the LTE link monitor, such as the image below.

Could you let me know how is this info obtained, that is shown in the link monitor.

Also, I am using NB-IoT and wanted to know the location of my cell tower. 

Its possible to get the location of the current cell I am connected to when I use LTE-M using a 3rd party software like : https://opencellid.org

But it is unable to show me the location when I am connected to NB-IoT. I wanted to know if there is any other software as such available to view or locate the NB-IoT cell towers ?

Regards,

Adeel.

Hi Adeel, 

Have a look at the Multicell Location sample that we provide to demonstrates how to use Multicell location library to get a device’s position based on LTE cell measurements. The information provided by the sample can then be used with a 3rd party software as you suggest. 

Kind regards,
Øyvind

Hi Oyvind,

I did have a look at that sample and I was able to get the TAC, Cell ID, MCC; MNC information. 

I have the location of my device but what I was trying to get is the location of the NB-IoT cell tower that I am connected to, or something like a coverage map that you have in the LTE link monitor.

I am unable to find the NB-IoT cell tower location using the 3rd party software. It only has LTE tower specific location.

Regards,

Adeel.

Hello Adeel, 

In LTE Link Monitor http://locationapi.org/ is used to provide the map. This should also be possible with nRF Cloud, using single cell location. Have a look at the nRF Asset Tracker (Asset Tracker v2) documentation on cell geolocation, which describes how to use nRF Cloud's geolocation API or Third Party API.

Kind regards,
Øyvind

Hi Oyvind,

Thanks for the links. I had a look at it and it seems useful. Will try that out. 

However, I am facing 1 issue wherein I am unable to locate my cell in the 3rd party API when its connected to NB-IoT.

With LTE-M, I am able to locate the cell tower using : https://opencellid.org/#zoom=18&lat=48.154429&lon=11.466856 , 

My MCCMNC is :26201 (Germany), TAC : 52015, Cell ID : 26512650, when using NB-IoT. Could you help me locate the cell tower location with these details through this 3rd party application ?

Regards,

Adeel.

Do you have the area ID for this cell as well? It's needed for nRF Cloud api.nrfcloud.com/v1
