System description

The mSafety platform consists of two main components: a wearable and a cloud backend.

The wearable is directly connected to the Internet without the need for pairing with a mobile phone. It features in-device sensors with algorithms to monitor activity, heart rate, sleep and stress, as well as a GPS for location tracking. In addition, it can be connected to external sensors via Bluetooth Low Energy or NFC. A global roaming profile ensures the wearable remains continuously connected in all environments.

The back-end provides the fundamental structures needed for mSafety wearables to interact with the customer’s cloud back-end servers in a secure and scalable way. It enables easy on-boarding of wearables and updating of software. In practice, an end user wears the mSafety device, which receives health data from a connected customer sensor. Information is displayed on the device and sent, end-to-end encrypted, to the customer’s backend - through the mSafety cloud backend.

mSafety customers develop their own unique mHealth application to be embedded in the wearable, and connected to the backend solution.

Simple set-up and installation
Authentication/authorisation
Secure wearable communication (MQTT/TLS)
Remote device configuration
Over-the-air software updates
Subscription management as a service
The mSafety wearable device features ultra-low power consumption in a variety of modes thanks to an advanced LTE release 13 CAT-M1 chipset, and power-efficient multicore microcontroller. These features allow for a battery life of 7 days or more in a reference case.
