ETSI TR 102 628 is aimed at establishing a dedicated, harmonized European spectrum designation for PPDR mission-critical Public Safety and Emergency Communications. This proposed resource would be a harmonized spectrum across Europe allowing interoperable and permanent PPDR networks to be established in the 300 MHz to 790 MHz band. It is proposed that such a network would cater for all narrowband, wideband and broadband PPDR applications requiring wide area coverage. The applications will be used for voice in Narrowband networks, and voice and data or data only in Wideband and Broadband networks. For local and temporary broadband PPDR usage, so-called 5 GHz [4,9 GHz] Broadband Disaster Relief (BBDR) applications, the current regulation may also be reviewed.
