A flexible R&D environment that advances spectrum technologies is needed to meet current and future spectrum requirements for the broadband communications, according to a report by the National Science and Technology Council’s Wireless Spectrum R&D Interagency Working Group (WSRD) that was recently submitted to President Trump.
“Today’s reports will help inform the National Spectrum Strategy and help ensure America wins the global race to 5G. The President has shown a strong commitment to U.S. leadership in 5G,” said WIA President and CEO Jonathan Adelstein. “I commend the White House for their focus on efficient spectrum use and for encouraging private investment in next-generation wireless networks.”
The report features with recommendations for R&D actions to increase the efficiency of spectrum use through spectrum agility, near real-time spectrum awareness, and adaptive spectrum decision making. The WSRD Interagency Working Group (IWG) recommended a whole-of-government approach to electromagnetic spectrum R&D and advocates public–private partnerships to achieve these priorities.
This report responded to the 2018 Presidential Memorandum on Developing a Sustainable Spectrum Strategy for America’s Future and contains recommendations for prioritizing R&D to advance radio frequency spectrum access and efficiency.
Priority onecalls for the government to pursue spectrum flexibility and agility to use multiple bands and new waveforms.
“Spectrum R&D is needed to improve the temporal use of federal and commercial spectrum,” the report said. “Wireless systems need new and improved radio frequency technologies that support the flexibility to use multiple bands. Careful evaluation of incumbent systems and assets should be pursued to ensure safe and reliable sharing of spectrum bands.”
Priority two is to improve near real-time spectrum awareness, such as near real-time network sensing and monitoring. In addition to providing more up-to-date information on network and spectrum environment changes, monitoring also supports enhanced interference detection and resolution to prevent degradation of systems or services provided. The increased use of lower-power and highly directional antennas presents a challenge as well as an opportunity in realizing spectrum awareness capabilities.
Priority three calls for an increase in spectrum efficiency and effectiveness through secure autonomous spectrum decision making.
The current methods of spectrum decision making and spectrum sharing need to evolve to support the future spectrum ecosystem. Future wireless networks are likely to be more decentralized and better able to react to changing environmental conditions. The spectrum ecosystem will benefit from systems that can make decisions in near real-time, autonomously and securely, and coordinated with other disparate wireless systems over a wide frequency range in the same geographic area, while balancing efficient use of spectrum with effectiveness of federal and private missions.
