Sx-Cell Broadcast delivers the public warning in the area the authority defines
Cell broadcast center in accordance with 3GPP TS 23.041. It disseminates the alert by cell, area or polygon in GSM and UMTS, without congesting the network. LTE and 5G are supported subject to validation with the operator's network.
Results for the operator
