Abstract
Smart public safety network is one of the hot topics in wireless communication. This chapter presents the design and development of first responders network (First Net) which provides broadband spectrum to the emergency service personnel at the time of disaster in a national level. In the same direction, the proposed design solves the problems of radio networks' interoperability. The smart public safety network uses incompatible radio systems and technologies in different frequencies to coordinate and collaborate works without any interferences. Smart radio network technologies aim to optimize the connections between different public safety organizations. An adaptive controlled system for different two-way radio networks interoperability is designed to increase the trust and reliability at the disaster and crisis times. The design usually depends upon the infrastructure and environmental condition of radio networks that already exist in the country. For simplicity, the presented design is focused on voice communications by accessing audio through commonly featured radio sockets. On the other hand, the existence of the third parties in the system such as the Internet, cellular, or even a console in large two-way radio systems reduces the reliability of the whole design and increases the cost and lack of time.
