Public warning and citizen services
The authority's alert reaches the defined area and citizens access services from any phone.
The demand on the operator
In an earthquake, flood or fire, the authority requires alerting every device in an area without congesting the network. Afterwards, citizens need guidance.
ATC's response
Sx-Cell Broadcast disseminates the alert by cell, area or polygon. Sx-USSD Gateway offers menus for shelters, reports and queries without data or an app.
