SafeDistance wearable

SafeDistance is a wearable from Lopos that uses ultra-wideband (UWB) technology to accurately measure the distance between people. It alerts them immediately if they come closer than the required distance.

Why choose the Lopos SafeDistance wearable?


SafeDistance can be configured using our app which connects to the SafeDistance wearable by Bluetooth. The social distancing parameters can be adjusted as can the measurement rate. You can even personalize the types (sound, vibration, light) and number of alerts you receive. SafeDistance can be easily reconfigured if guidelines on social distancing change.

No privacy issues

SafeDistance does not log any information whatsoever – no personal data or location details – and is therefore GDPR compliant by design. As such, there are no privacy concerns for your employees who can rest assured that no personal data is being stored or tracked. Rollout in your company can take place very quickly as unions and HR will have no issues supporting SafeDistance.

Ready to use

Simply switch on the SafeDistance wearable and you’re ready to go. There is no expensive infrastructure required such as beacons or gateways.

Repurposing your investment

We use over-the-air software updates to enable new features on your device. We are constantly adding to these social distancing features and working on other functions such as high-precision localization, collision avoidance, safety zones and access control.

Extremely accurate

In contrast to wearables that use conventional Bluetooth or Wi-Fi signals for location tracking, SafeDistance uses ultra-wideband. UWB measures distances much more accurately, with an error margin of less than 15 centimetres. Bluetooth, in comparison, has an error margin of 2 to 5 metres. This means there are no false alarms when using SafeDistance. The wearable only alerts when you actually get too close.





Ultra-wideband technology

SafeDistance uses revolutionary ultra-wideband radio technology. Emitting low-energy signals at high speeds and bandwidth, UWB is uniquely suited for a location- and distance-tracking wearable compared to other wireless technologies such as Bluetooth.

Three alarm types

Three alarm types

SafeDistance has multiple types of alarms that are activated when social distancing is not respected: there is an audible beep (85 dBA), the device vibrates, and a red LED lights up. Administrators can choose to use just one of these alarms or any combination of the three at the same time.


Immediate feedback

Find out straight away if you get too close to someone. The distance between users is measured every 1.5 seconds, so there’s hardly any delay between the moment when the set distance is broken and the alarm being triggered. This immediate feedback helps you stick to social distancing guidelines better.


Long battery life

Long battery life

SafeDistance can remain active for 2 to 5 days on a single battery charge, even when the shortest measurement interval of 1.5 seconds is set. It takes just three hours to fully charge the device with the USB cable supplied. In sleep mode, battery life can last up to several years.

Always active

Always active

To ensure social distancing is respected at all times, SafeDistance cannot be switched off while in use as standard. Employees cannot switch the device off to prevent alarms from being triggered if they do not keep their distance. It is only switched off during charging or if it’s not used for a couple of hours.



SafeDistance is optimized for high-volume deployments and does not suffer from interference. No matter how many devices are active in the same area, they will not interfere with one another so performance remains optimal.

Configure your SafeDistance wearables with our free mobile app

You can customize the settings of your SafeDistance wearables with our free mobile app. The following can be configured:

  • Alarm distance (default: 1.5 metres)
  • Alarm type: sound, vibration, LED light or a combination of these (default: all three)
  • Alarm latency: how fast should the wearables activate the alarm? You can add a latency to this, so the alarm doesn’t go off when passing each other in a hallway, for instance (default: 1 second)
  • Device firmware update: when we release new firmware with new features, you can update your SafeDistance wearables using the configuration app
  • Inter alarm delay: once the alarm activates, the inter alarm delay determines how frequent the alarm sounds. If set to 10 seconds, the alarm will activate every 10 seconds for as long as the wearables are too close (default: 1 second)
  • Multiple alarms: you can for instance set a vibration alarm for 2 metres and a sound alarm for 1.5 metres. Or a LED light and vibration alarm that activate immediately, combined with a sound alarm that activates after 5 seconds
  • Whether or not the users can turn off the wearable using the button (default: no)
  • Whether ‘mouth mask mode’ is allowed: when it is, your employees can work close together if necessary. They should then wear a mouth mask, put the wearable on mouth mask mode and the alarm will not activate for 5 minutes (configurable) (default: no)
  • Turn on by movement: when taking the wearable out of the charger, it automatically turns on because of the movement







You can adjust the SafeDistance-wearable to your situation. Not only through the different alarms or configurable distance, but also thanks to the accessories that let you wear and charge the devices the way that suits you best.
