People density prediction

Risk management in high-density urban areas.

Your job is to protect the public. We use mobility data to identify large gatherings of people in small geographic areas, allowing you to create data-driven safety measures.

For civil protection, events and drone operators

Using mobile phone data and other parameters, we calculate the number of people to be expected in a particular place at a particular time. This makes it possible to prepare security measures and plan operations and events in advance. Drone operators use the information to perform drone flight risk analyses.

A beta version of Swisscom Broadcast’s People Density Prediction Service is now available.

Why Swisscom Broadcast 


Swisscom has a high market share in mobile communications, which results in a small margin of error when extrapolating the data to all mobile subscribers. 


We have many years’ experience in data-driven solutions and the analysis of mobility data. 

Data protection

We use highly anonymised and aggregated data from the Swisscom mobile network. The service complies with the Swiss Data Protection Act. Privacy is assured.

We use aggregated mobility data from the mobile network. This provides anonymised information about the mobility behaviour of the population. 

The legal basis for these services and associated data processing is Art. 45b of the Swiss Telecommunications Act (TCA). Under this regulation, telecommunications service providers may process anonymous location data of their customers or, with their consent, may also process location data for services outside of the provision and billing of telecommunications services. 

The services use data that is generated when Swisscom customers use a mobile device: the IMSI number of the SIM card, the date and time the SIM card interacted with the mobile network and the identifier of the mobile communication mast with which the SIM card interacted. 

No, this is not possible. The reports provided by the services are an approximation, rather than a precise reflection of reality. Swisscom can only determine the position of a SIM card approximately for technical reasons. The median position of a SIM card determined by Swisscom differs from the actual position by around 130 metres. The median represents the radius. In reality, therefore, the position of a SIM card determined by Swisscom is somewhere within a circle of 260 metres’ diameter and an area of around 53,000 m2. As a result of these discrepancies, the position determined by Swisscom may appear in a different quadrant than the one in which the SIM card was actually located. Identification of a SIM card holder is technically not possible under these circumstances, especially given the fact that the reports represent historical information and a k-anonymity of 20 is guaranteed by default. 

Yes. The holder of a SIM card can opt out of location or mobility data reporting via the online Customer Center or the Swisscom hotline.
