Developing a comprehensive roadmap for new commercially available spectrum is necessary to ensure the successful deployment of future mobile networks. Balancing both licensed and unlicensed spectrum is vital for the mobile industry. The upper mid-band spectrum, ranging from 7.125-15.35 GHz, is key to leveraging existing infrastructure for increased capacity. 5G Americas emphasizes identifying new spectrum integral to a U.S. National Spectrum Strategy pipeline, ensuring rapid commercialization, and sustained technological leadership.
The International Telecommunication Union (ITU) for International Mobile Telecommunications (IMT)-2030 has codified various usage scenarios that form the basis for spectrum needs. These scenarios highlight the necessity for high data rates and wide-area coverage for applications like immersive experiences, next generation healthcare monitoring, human-machine interfaces, and Joint Communications and Sensing (JCAS).
Key topics covered in this latest 5G Americas white paper include:
- U.S. spectrum position compared with other countries
- Anticipated spectrum needs from 2027 to 2030
- Desired spectrum characteristics of target bands
- Techniques to enable use of cellular systems in new bands
- Current and future use of mmWave
- Sub-THz spectrum for new 6G use cases
- ITU WRC-23 Decisions
“5G Americas supports the 7.125 to 15.35 GHz spectrum range, especially below 10 GHz, for licensed mobile operations for its balance in capacity and coverage. Opening bands in this range involves exploring relocations and sharing strategies. Additionally, mmWave bands are important for deployments in dense locations like urban cores, transportation depots, busy streets, and entertainment venues, and also for fixed wireless access deployments. Sub-THz bands offer very large bandwidths that may be suitable for specialized use cases,” said work group co-leader Aleksandar Damnjanovic, Principal Engineer/Manager at Qualcomm Technologies Inc.
