The application is currently supported on Android and Windows 10 Mobile devices.


CellMapper servers calculate the data that users have sent and creates graphical representation of it in the map delivered by Google Maps, witch can be browsed directly from the Android App or CellMapper webpage. The model can not account for certain variables though, so in order to get reliable data one should keep the measuring phone in as clear and unobstructed area as possible. An ideal measuring setting is as unobstructed as possible, such as large fields of prairie, but for instance in cities obstacles are unavoidable. When measuring one should move in 1/2-3/4 circles at different distances around the presumed base station in order to get the most accurate results.

* Battery consumption rise (looks for GPS signals and checks network quality)
<!--T:6-->
* Screen won't turn off while application is running (More battery consumption!). If you have a phone with an Amoled -screen you can turn it off for the duration of the measuring from the applications settings.
* Battery consumption will increase while looking for GPS signals and checking network quality.
* Base station location in urban areas is best determined by doing round trips of city blocks. At more rural locations you should do larger sweeps to save time. You will get the best result on flat ground.
* The screen may not turn off while the application is running (this consumes more battery). If you have a phone with an AMOLED screen, you can turn this feature off for the duration of the measuring from within the CellMapper app settings.
* Ensure that you have a sufficiently good connection to the base station as well as a GPS connection.
* Base station locations within urban areas are best determined by going in round trips of city blocks. In more rural locations, you should do larger sweeps to save time. You will get the best results while measuring on flat ground.
* Using the application requires that you have a subscription with the operator whose 2G/3G/4G network you are trying to measure. You can only measure stations in the network you are actively connected to, so for instance you can't locate a 4G base station if you are in a 3G network. Usually 2G/3G/4G/4G+ cells can all be in the same base station, and even be sent from the same panel antenna.
* You have a sufficiently good connection to the base station as well as a GPS connection.
* The application can show that a base station can cover areas up to a hundred kilometers. These errors can be created if the network data collected by the application has great resemblance with some other base station or if the phone has calculated incorrect GPS-data. At this moment these "orphan cells" can't be removed by the user and they are left on the map.
* Using the application requires that you have an active plan with the operator whose 2G/3G/4G network that you are attempting to measure. You can only measure stations on the network that you are actively connected to. Therefore, you will not be able to measure a 4G base station if you are currently connected to a 3G network. Usually 2G/3G/4G/4G+ cells can all be in the same base station, and even be sent from the same panel antenna.
* The application may indicate that a base station is covering an area several kilometers or miles beyond what is typical. This type of error can occur if the network data collected by the application is similar to data found on another base station or if the phone has calculated incorrect GPS data. At the moment, these "orphan cells" cannot be removed by the user and are left on the map.

First Time Startup

CellMapper is a useful app for locating 2G/3G/4G/5G base stations. The application measures the signal strength and other network data collected by end users and uses the data collected to locate network base stations and their coverage. The application is currently supported on Android and Windows 10 Mobile devices.

CellMapper servers calculate the data that users have sent and creates graphical representation of it in the map delivered by Google Maps, which can be browsed directly from the Android App or CellMapper webpage. The model can not account for certain variables though, so in order to get reliable data, one should keep the measuring phone in as clear and unobstructed area as possible. An ideal measuring setting is as unobstructed as possible, such as large fields of prairie, but for instance in cities obstacles are unavoidable. When measuring, one should move in 1/2-3/4 circles at different distances around the presumed base station in order to get the most accurate results.

The application supports real time transfer, so the data collected is sent to Cellmapper's servers as you measure. You can also manually send the data after measuring or resend already collected data. After the files have been sent to the server, they are processed within minutes if there is not much load on the servers at the time. If the servers are under heavy load then processing data can take up to hours or even a full day. The delay of processing speed is a known issue, and will be addressed in the future.


While using CellMapper, it is important to understand that:

  • Battery consumption will increase while looking for GPS signals and checking network quality.
  • The screen may not turn off while the application is running (this consumes more battery). If you have a phone with an AMOLED screen, you can turn this feature off for the duration of the measuring from within the CellMapper app settings.
  • Base station locations within urban areas are best determined by going in round trips of city blocks. In more rural locations, you should do larger sweeps to save time. You will get the best results while measuring on flat ground.
  • You have a sufficiently good connection to the base station as well as a GPS connection.
  • Using the application requires that you have an active plan with the operator whose 2G/3G/4G network that you are attempting to measure. You can only measure stations on the network that you are actively connected to. Therefore, you will not be able to measure a 4G base station if you are currently connected to a 3G network. Usually 2G/3G/4G/4G+ cells can all be in the same base station, and even be sent from the same panel antenna.
  • The application may indicate that a base station is covering an area several kilometers or miles beyond what is typical. This type of error can occur if the network data collected by the application is similar to data found on another base station or if the phone has calculated incorrect GPS data. At the moment, these "orphan cells" cannot be removed by the user and are left on the map.

Usage

Map

Screenshot 20170324-094753.png

The map opens from the left side main menu.

In the maps tab you can see the location of already mapped base stations. The application will automatically only show the base stations of the current network being used (LTE in the picture). The location of base stations can also be viewed from the Cellmapper webmap.

The base station is marked on the map as a red pin in mobile and a red arrow in a browser. A blue pin refers to your own location and the black line tells you which station you are connected to. By clicking on the base station you can see it's range as a black zone. Light green indicates best signal quality, dark green good quality, black average quality and red the weakest signal quality.

A green pin (on the mobile app map, a red pin) indicates a user has located a tower. You can locate a tower on the web map when you have reached over 50,000 points and 50 cells (requires account).

By pressing Select Provider (Search Icon) in the header you can switch the operator and network so that you can inspect base stations of other networks.

Send data to server

Open the left side menu and select Upload and Statistics. You should always upload your newly measured base station so that another user won't have to redo it, and they can instead view it from the map. The Cellmapper map is updated nearly instantaneously.

Screenshot 20170326-022716 (1).png

Select the Upload icon after this so that the data will be sent to the server. We recommend that you also turn on the Enable instant upload feature from the settings, so that you don't have to press the button every time.

Account

With a Cellmapper account, you can track how many towers you have recorded, and locate those towers on the web map, etc.

You can register for a Cellmapper account here: here.
