Taiwan Economic Research Monthly Spectrum Planning for Future Communications: Evolution and Challenges from B5G to 6G ‧ The radio frequency spectrum represents a critical and scarce resource for telecommunications advancement. As technology evolves and demands increase across mobile and satellite communications, the equitable, harmonious, and efficient utilization of spectrum resources has become a crucial challenge for nations worldwide. In the Beyond 5G era, the rapid development of LEO satellite communications, exemplified by systems like Starlink, propels progress toward a three-dimensional network that spans land, sea, and air in the 6G era. Everyday communications are transitioning from solely terrestrial networks to non-terrestrial networks such as satellite communications and high-altitude platform communications, leading to greater demand for spectrum resources and becoming a cornerstone of national network resilience. Furthermore, PDR systems ensure seamless communication for emergency response units. In recent years, nations have actively leveraged mobile broadband and related applications to allocate PPDR frequency bands and construct supporting networks. This feature articles delve into the future of LEO satellite communications, the rise of high-altitude communication platforms, an analysis of PPDR models, and spectrum planning. It examines the trends in high-altitude platforms, LEO satellites, direct-to-cell satellite connectivity, and public safety and disaster relief communications, as well as the corresponding spectrum planning and allocation trends. In light of the anticipated development of 6G by 2030, this feature articles also analyzes the current state of spectrum usage and future spectrum release plans in Taiwan. By synthesizing domestic spectrum utilization data and addressing key international issues, it provides forward-looking recommendations for spectrum planning in preparation for the 6G era.
