CellMapper is a powerful tool that allows users to identify the locations of cellular masts (towers) in their area. Whether you’re aiming to improve your 4G signal or optimise the placement of your radio equipment, CellMapper can be invaluable. Here’s a step-by-step guide on how to use it effectively.

Step 1: Access the CellMapper Website
Navigate to the CellMapper website.
Click on the Menu button (usually located in the top left corner).
Select Search from the menu.
Enter your site’s address or postcode into the search bar and press Enter.
This will display the general location of your site on the map.

Step 2: Identify the Cellular Provider
Once the location is loaded:
Close the Search menu by clicking the ‘X’ or another relevant button.
Click on Provider in the menu.
In the provider list, search for the name of your SIM card provider. For example, if your SIM is from EE, select EE.
This will filter the map to show only the cellular towers for that specific provider.

Step 3: Find Cellular Mast Location and Compare Tower IDs
After selecting the provider, you’ll see one or more tower IDs displayed on the map. In this example, two towers appear for EE: Tower ID #27573 and Tower ID #27966.
To determine the optimal tower for your use case:
Click on each tower to display its antenna beam on the map.
Analyse the beam direction to find the one that best aligns with your location.
For instance:
Tower ID #27573

Tower ID #27966

From the images above, it is clear that Tower ID #27966 provides the best alignment for directing the 4G radio. Your 4G radio must be installed with a direct line of sight to this tower for optimal signal quality.
Step 4: Verify the Direction and Distance with Google Maps
To further refine the installation process:
Open Google Maps and switch to Satellite View.
Locate both your site and the selected cellular mast.
Measure the distance and note the precise direction for installation.
This additional step helps ensure the 4G radio is aligned perfectly.


Conclusion
By following these steps, you can easily find the location of the best cellular mast using CellMapper. Combining this information with tools like Google Maps allows for accurate alignment of your 4G radio equipment, ensuring optimal performance and signal quality.
