Cell Broadcast
Method of sending messages to multiple mobile phone users
Cell Broadcast
Cell Broadcast (CB) is a method of simultaneously sending short messages to multiple mobile telephone users in a defined area. It is defined by the ETSI's GSM committee and 3GPP and is part of the 2G, 3G, 4G and 5G standards. It is also known as Short Message Service-Cell Broadcast (SMS-CB or CB SMS). Cell Broadcast is different from the regular Short Message Service (which is also called Short Message Service-Point to Point / SMS-PP to distinguish it). Cell Broadcast is a one-to-many geo-targeted and geo-fenced messaging service, which typically targets all handsets connected to a specific network cell. Cell Broadcast technology is widely used for public warning systems.
