Rohde & Schwarz, in collaboration with LG Electronics Mobile Comm., U.S.A., Inc., have successfully verified Wireless Emergency Alerts (WEA) 3.0 features related to GEO-Fencing using an LG G8 ThinQ mobile smartphone.

The Rohde & Schwarz system consists of the CMW500 radio communication tester and the SMBV100B vector signal generator. It verifies mobile device signaling according to WEA 3.0 GEO-Fencing specifications. This same system can also cover 3GPP conformance and network operator test plans for LTE, WLAN, WCDMA and GSM location-based services.

Wireless Emergency Alerts are a critical part of the nation's emergency readiness system for warning the public about dangerous weather, missing children and other types of emergencies. Geographic targeting is a necessary mobile device feature as alerting citizens not affected by a specific emergency could cause unnecessary panic and safety risks.
