ETSI TR 102 628旨在为PPDR建立一个专门的、协调的欧洲光谱名称 关键任务公共安全和应急通信。这项拟议资源将是一项协调的资源 欧洲范围内的频谱允许在300 MHz至 790兆赫频段。据提议，这样一个网络将满足所有窄带、宽带和宽带PPDR的需求 需要广域覆盖的应用程序。这些应用程序将用于窄带网络中的语音，以及 以及数据或仅在宽带和宽带网络中的数据。 对于本地和临时宽带PPDR使用，所谓 5 GHz[4,9 GHz]宽带救灾（BBDR）应用，也可能会审查当前法规。

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.
