The fifth-generation mobile communication system (5G) with its high speed/high capacity, ultra-low latency, and massive device connectivity characteristics has expanded worldwide. Through its innovative technologies, the 5G network contributes not only consumer services but also industrial services. A medical field is one of the important industrial areas where the 5G network is expected to be effective. Studies and activities focused on telemedicine using the 5G network have been reported from various parts of the world. In this chapter, after presenting overseas cases, we introduce our solutions including advanced telemedicine using experimental and commercial 5G networks collaborating with partners such as university hospitals and those in industry. To introduce the 5G network to telemedicine, accumulating technology toward advanced telemedicine and practical demonstrations in a commercial environment are key to success. 5G technologies will become more sophisticated, and the next generation of mobile communication systems could further enhance telemedicine in the future.
