Frequently Asked Questions

The G-SAFE lone worker device model uses a few technologies for communication. This device first of all uses cellular communication to communicate it data. It has a cellular antenna for communication, with voice call function. Each device has its own SIM card and unique number.

The G-SAFE also has a GPS antenna to pick up Geolocation position using Latitude/Longitude, as well as a special motion sensor for the detection of fall which uses a special calibration of gravity and speed changes, to simulate a fall detection.  

All its data is relayed via cellular communication to a server, and users have secured access to this information via a Web/Mobile interface with functions such as Status, track, history, reports and notifications.

Why Indoor Location Doesn't Work:

Simply because GPS doesn't work indoors. Yes, this little gem of technology that allows even those who don't have a sense of direction to find their way around the world, is unable to orient you in a building around the corner! Why?

In order to determine your position outside, GPS uses radio signals emitted by the various satellites orbiting the Earth, but once inside, these signals are blocked by various obstacles (walls, roof, furniture, etc.). The most recent GPS devices receive a signal indoors, but their accuracy is still insufficient to orient oneself correctly.

The other problem with a traditional GPS is that it processes the signal in a linear fashion; So it can't figure out which floor you're on. In addition, its signal decreases as you descend into the floors, until it disappears into the basement. Hence the usefulness of an indoor geolocation system.

If the device is full at the beginning of use and depending on the activity of the wearer (whether moving or not, the strength of the signal network in the area and battery level), it can last up to 2 days before requiring a return on the charge. 

Our recommendation, however, is to put the device on the charge after end of day use so that the next user can start his intervention with the battery full.

The G-SAFE model device: Once the recharge is 100% complete, after a few minutes the Device will turn off in order to avoid premature wear of the battery and as a safety measure. 

Next time using the device, the user must turn it on, check its battery % and start their day. At the end of his shift, he just has to put it on charge for the next use.
