WASHINGTON, September 10, 2019- Federal agencies speaking at radiofrequency symposium hosted on Tuesday by the National Telecommunications and Information Administration Symposium expressed doubts that any kind of a national spectrum strategy would be useful.
Addressing speculation that the Commerce Department's NTIA might unveil such a national spectrum strategy, the officials each seemed focused on their doubts that such a strategy would be beneficial for their respective agencies.
Spectrum management needs to meet constantly changing demands, said R. J. Balanga, senior regulatory and policy adviser at the National Aeronautics and Space Administration. Increased spectrum usage and higher data-rate transmissions are required for human and robotic operations in space.
NASA’s main objective, he said, is to enhance interoperability by further cooperation with the commercial space industry and its international partners.
The Department of Defense occupies a great number of spectrum bands, said Colonel Frederick Williams, director of spectrum policy and programs at the Pentagon. He said spectrum has becoming increasingly congested.
Agencies must work together to combat spectrum issues, he said. The Citizens Broadband Radio Service, for instance, was established by the Federal Communications Commission as a way for shared wireless broadband use of the 3.5 GHz band.
Karen Van Dyke, principal technical adviser for Global Positioning Systems at the Department of Transportation, said that spectrum affects all modes of transportation. Therefore, it’s important that GPS are protected from harmful radio-frequency interference.
Furthermore, she said, close cooperation with private industries is required to best utilize spectrum innovation.
The government has so many layers of spectrum management that it’s difficult to determine the exact process, said Ian Atkins, director of the Federal Aviation Administration spectrum strategy and policy.
The FAA is committed to utilizing the least amount of spectrum possible, he said. However, what the agency is looking for is a return of investment to make sure that valuable spectrum programs are enacted.
With 5G approaching mass deployment, efficient spectrum management is key.
Dynamic spectrum sharing as well as extended range millimeter waves are going to dramatically increase 5G deployment, said Dean Brenner, senior vice president for spectrum strategy and technology policy at Qualcomm.
The hype surrounding the deployment of wireless 5G technology demonstrates that the public often gravitates its focus on a single set of technologies, said Christopher Szymanski, director of product marketing and government affairs at Broadcom. But there needs to be focus on the backhaul and wireless aspects of spectrum as well.
Cisco has projected increased usage of unlicensed spectrum in the coming years, said Szymanski. However, the U.S. lacks enough channels of spectrum to keep up with demand.
Hence why spectrum and infrastructure policies are necessary on both the state and federal level, said Hank Hultquist, vice president of federal regulatory for AT&T.
