Establishing the network saturation of the areas your Lone Workers are operating in is imperative for a duress solution to deliver. The GPS location and panic may always work, but if there's no network to carry the signal out, nobody can respond. So a cell based duress device for staff who are regularly out of cell cover is pointless. Yes the GPS will always work while the device can see the sky, but if there’s no cell network to carry the alert to a responder, it’s dangerous to even have them in use.
If your Lone Workers are out of cell cover more than 10% of the time (or whatever percentage you deem to be unacceptable risk), they may need a satellite or hybrid solution. Hybrid solutions such as G7X will still work if staff go indoors, however a pure satellite solution such as inReach from Garmin, will not work inside. If the inReach is used, we can put other processes such as check ins in place to mitigate this risk.
The only satellite network you should be relying on for Lone Workers is iridium. It’s the only satellite network with a large number of satellites (67) and it has forwarding technology. This means if the satellite that receives the SOS can’t see the earth station, it will forward it to one that can. Good devices such as inReach and G7X will also continue to send the signal until it’s confirmed as received by the satellites. And the device will confirm to the user that the alert has been received. This is a vital function for workers who are alone or in remote locations to have Peace of Mind.
Inferior satellite devices with just a SOS button and no real communication or confirmation to the Lone Worker that the alert has been received, and on other satellite networks with no forwarding technology should not be relied upon for Lone Workers. We hear of constant failures with these recreational type devices.
If you have a vehicle telematics solution in use, it’s possible we can integrate a pendant and the signals from your provider so that we can monitor alerts. Please note however, while some solutions can be fitted with an iridium satellite modem, most telematics solutions rely on cell cover to send the information. This means the information will be sent when the vehicle is back in cell cover, which of course is of little use if it’s an SOS, or impact alert and the vehicle is no longer moving.
