What is a CrowdRanger?

Remove the guesswork from social distancing

CrowdRanger is wearable social distancing and contact tracing technology made easy to deploy. The wearable CrowdRanger warns the user, visually, audibly, and haptically, when the physical distance with another user is compromised.

Besides real-time protection the device logs interactions between devices, not users. Meaning the CrowdRanger enables contact tracing as a stand-alone device without requiring user registration.

How does it work?

Real-time protection

When 2 or more CrowdRangers breach the safe distance the devices alert their user. The alarm stops once the users move apart and comply with the safe social distance. The alarm escalates from a visual red light to a loud noise, based on the measurement of the following factors:

  • Distance between devices
  • Time spent
  • Motion of the device

Wearable Social Distancing with CrowdRanger Explanation. Alerts when social distance encroachment occurs.

Contact Tracing

The devices record the distance and time spent when the safe distance is breached. This data is stored on the devices for a period of 14-28 days. When the need arises, an administrator can access the data with a provided user-friendly tool.


Privacy was a key part in the design process. The device does not save personally identifiable data and users are not required to register when using the device, thus meeting the EU’s General Data Protection Regulation guidelines.

What sets it apart?


The essence of a social distancing wearable is its accuracy, which translates to the negation of false positives or negatives.

The CrowdRanger is based on Ultra-Wideband (UWB) and achieves accuracy up to 5 centimeters (2 inches). The accuracy is not impacted by the number of devices in close proximity.

Another benefit of UWB is that the device can be worn around the neck, on a belt clip, or in a user’s pocket without losing effectiveness.

Infinite scalability

The Crowdranger is a stand-alone device as it does not require additional hardware installation. So no matter the layout of your infrastructure or event space, users are always protected.

Future proof

As COVID-19 is a temporary crisis we have planned for the obsolescence of the CrowdRanger. All devices can be returned to be recycled and upcycled into our other products.

CrowdRanger Pro

Provide anonymous and opt-in contact tracing

In addition to alerting the wearer, the CrowdRanger Pro internally logs every safe distance breach. Both the time and the serial number of the other device(s) are stored. No personal or localization data is logged.

Safety now and for the future

In the unfortunate case that an employee contracts COVID-19, the data can be extracted from that person’s CrowdRanger Pro. The list consists solely of time stamps and serial numbers.

We deliver an anonymous solution. It is up to you and your team to decide whether you link the serial number of a CrowdRanger to its user.
