5G Spectrum Research

With the growing demand for communication and the rapid development of global mobile communication technology, the fourth generation of mobile communication can no longer meet the needs of people in their working lives for mobile network communication, and the fifth generation of mobile communication is born. This paper first introduces three strategies for the use of the 5G spectrum, namely spectrum dedication, spectrum re-farming, and spectrum sharing. Secondly, it introduces the three main application scenarios for the 5G spectrum, namely enhanced mobile broadband (eMBB), ultrahigh reliability and ultra-low latency services (URLLC), and massive IoT communications (MTC). The presentation concludes with a summary of the impact of the 5G spectrum in today’s society and an outlook on its future development.
