What You'll Learn
CellMapper is a crowd-sourced cellular tower and coverage mapping service
To get started with CellMapper, users need to install the application on their Android or Windows 10 Mobile device. They should also read the first startup instructions and FAQ page for more information. When measuring, it is recommended to keep the phone in a clear and unobstructed area to ensure reliable data. Additionally, moving in half to three-quarter circles at different distances from the base station can provide more accurate results.
Once users have collected their data, they can manually send it to the servers or enable the instant upload feature. The data is then used to update the map, which includes signal trails that may take up to three weeks to appear. Users can also view the "last seen date" for towers they connected to, which updates within minutes.
CellMapper also offers a web map where users can see different colours representing the first six digits of the md5 hashed U/E/ARFCN value when clicking on a tower. This feature can be disabled in the WebMap settings.
Overall, CellMapper provides a valuable service for users to understand and improve their mobile network coverage by crowd-sourcing tower locations and signal information.

Users can upload data to improve the accuracy of the map
CellMapper is a crowd-sourced cellular tower and coverage mapping service. It 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.
The CellMapper servers calculate the data that users have sent and create a 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 cannot account for certain variables, so in order to get reliable data, one should keep the measuring phone in as clear and unobstructed an area as possible. An ideal measuring setting is as unobstructed as possible, such as large fields. When measuring, one should move in half to three-quarter 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, processing data can take up to hours or even a full day.
To upload data, 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. 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. With a CellMapper account, you can track how many towers you have recorded and locate those towers on the web map.

The map is updated nearly instantaneously
CellMapper is a crowd-sourced cellular tower and coverage mapping service. It is a cellular coverage map application that allows users to check their provider's mobile network coverage and tower locations. The CellMapper servers calculate the data sent by users and create a graphical representation of it on the map delivered by Google Maps. This map can be viewed directly from the Android App or CellMapper webpage and is supported by most modern browsers.
The Cellmapper map is updated nearly instantaneously. 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 previously collected data. The "last seen date" for towers you connected to should update within minutes. However, there can be a delay in the signal trails appearing on the map, which may take anywhere from one day to three weeks.
To ensure your data is uploaded and the map is updated, open the left-side menu and select "Upload and Statistics." Always upload your newly measured base station so that another user doesn't have to redo it. You can also turn on the "Enable instant upload" feature from the settings to automate this process. With a CellMapper account, you can track how many towers you have recorded and locate them on the web map.
It is important to note that CellMapper is entirely crowd-sourced, so the more data you upload, the more accurate the map becomes. Adding new points to previously unmapped areas is the most helpful. Going over the same route multiple times can help fill in any dropouts or signal strength variations, but remapping the same location repeatedly does not significantly improve the map.

Signal trails can take up to 3 weeks to appear
CellMapper is a crowd-sourced cellular tower and coverage mapping service. Users can record and display mobile network information and quality, which is then processed and displayed on a map. The time taken for signal trails to appear on the CellMapper map can vary. While some users have reported seeing new trails in less than 24 hours, others have experienced delays of up to three weeks or even longer. The variation in time may be due to several factors, including the volume of data, location, and carrier.
The processing time for signal trails can differ depending on the volume of data being submitted by users. For instance, a user with a large volume of data from a multi-state driving vacation experienced a delay of four weeks, suggesting that a glut of data from a single user might slow down the processing queue. In contrast, another user noted that their “bread crumb trails" from June took 6.5 weeks to fully populate at all map zoom levels, indicating that the processing time can be influenced by the level of detail or zoom required for the data to appear accurately on the map.
The location where the data is collected can also impact the time taken for signal trails to appear. In densely populated urban areas, it can be challenging to determine who found a new tower and when, leading to potential lag times before it appears on the map. Additionally, some carriers may generate trails at different times. For example, a user reported that their AT&T and T-Mobile data took about two weeks to appear, while another user observed that T-Mobile and Verizon trails often took weeks to show up.
It is worth noting that CellMapper servers process and create graphical representations of user-submitted data, which is then displayed on the map. This process can be affected by various variables, such as obstacles in urban areas or changes in signal strength, which may contribute to the time it takes for signal trails to become visible. To ensure reliable data, users are advised to keep their measuring phones in clear and unobstructed areas whenever possible.
While the CellMapper map is updated nearly instantaneously, the processing and appearance of signal trails can take longer. Users are encouraged to enable the “Enable instant upload” feature in the settings to streamline the data upload process. Additionally, adjusting the recording interval from the default of 5 seconds to 1 second can significantly increase the amount of data the servers need to process, potentially resulting in faster trail updates. However, a shorter recording interval is generally recommended only when traveling at high speeds to view data at a very close zoom level.
