摘要: Commercial mobile operators’ networks will be used for public safety communications due to demand wireless broadband services, new applications, and smart devices. Existing dedicated professional radio networks, such as terrestrial trunked radio, Tetrapol, project 25, are based on narrowband technologies hence their data bandwidth is limited. This paper studies how critical needed, e.g., by ambulance personnel, rescue squads, law enforcement agencies can implemented over a 5G network. The most important technology enablers described test network architectures in our given. We focus two different use cases. First, enable priority commercial Second, create rapidly deployable emergency tactical operations. Tests done with the systems real show that both approaches very promising future users. Techniques slicing licensed shared access provide means support mission applications any environment.
