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.
Predictive drone flight planning and safety assurance in high-density environments.
The population is growing, especially in urban areas. In some places, the density of people can become very high at certain times. Knowing how many people there will be at a particular time and place enables the predictive creation of risk analyses and safety measures in order to manage large crowds and direct visitor flows. Our People Density Prediction uses Swisscom mobile data and other selectable parameters to calculate the density of people to be expected at a specific location at a specific time. These predictions are extremely valuable for emergency service operation planning as well as the organisation of events and festivals. Emergency and rescue services, companies, municipal authorities and drone operators can use the different basic functions of the services individually.
The service is currently in beta. Find out more about the customer-centric further development below.

Which data do the services use?
We use aggregated mobility data from the mobile network. This provides anonymised information about the mobility behaviour of the population.
What is the legal basis for the services?
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.
What data must be processed for the services to provide the information requested by the customer?
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.
Is it possible for the reports provided on the services to be used to identify or perhaps monitor the holders of SIM cards?
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.
Is it possible to opt out of location data reporting for your own SIM card?
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.
