SHIELD 24/7 uses the GSM network to communicate with the CRMS.
In emergency situations, if the GSM network fails, SHIELD 24/7 intelligently switches to Thuraya satellite communications. This minimises the chances of delivery failure and dramatically increases the reliability of SHIELD 24/7.
SHIELD 24/7 can rely on the Thuraya network if wthe building monitored is located outside the GSM coverage area.
