Don’t Be Confused About “Dynamic Spectrum Sharing”—The White House and Many In The Wireless Industry See It As the Best Path Forward for U.S. Spectrum Management

You may have seen recent coverage from LightReading stating that Dynamic Spectrum Sharing (DSS) faces a “quiet sunset.” The headline alone may suggest that all DSS is dead; however, a deeper read brings to life an early attempt by each carrier individually to utilize both 5G and LTE on the same band of spectrum to support their transition. The article goes on to discuss how this DSS model wasn’t ideal and that carriers are now discontinuing its use as a temporary solution to challenges introduced some five years ago.


Please don’t be confused or misled: dynamic spectrum sharing in its current form is very much alive and well. Today, the term has come to describe a shared environment whereby all carriers, protocols and services operate in the same band to prioritize and optimize the limited available spectrum for the benefit of businesses, government organizations, and our country’s macro-economic potential. It offers new capabilities and is being pursued by the White House, the DoD, and commercial and private organizations to provide improved, maximized, real-time access and use of wireless spectrum across the United States.


The recent Presidential Memorandum on Modernizing United States Spectrum Policy and Establishing a National Spectrum Strategy clearly outlines a roadmap to more efficiently provide access to support growing demands for wireless spectrum from U.S. businesses, the public, government, and military agencies—and DSS is a major part of making this possible. Further, the United States is actively utilizing shared spectrum technology to more efficiently use the Citizens Broadband Radio Service (CBRS) on the 3.5 GHz band between government organizations, wireless carriers, WISPs, businesses and public users. DSS may also offer a next step in making CBRS usage much more effective by enabling real-time monitoring and management capabilities.


Digital Global Systems (DGS) is at the forefront of spectrum sharing technology policy, planning, and development. ABI Research says DGS’ dynamic spectrum sharing approach is “valuable and credible” and that dynamic spectrum sharing “will not only be necessary for the future of GAA (General Authorized Access) deployments, but will also significantly augment its capabilities.” Further, DGS has the intellectual property (184 issued and allowed patents, with 48 patents pending) and demonstrable solutions to enable true dynamic spectrum sharing—today. The company has just been awarded (Jan. ’24) Frost & Sullivan’s 2024 Global New Product Innovation Award for revolutionizing 4G/5G network optimization and enabling dynamic spectrum sharing. The company is partnering with Celona, Dell, Intel, Airspan and others to deploy its patented RF awareness and its dynamic spectrum sharing technology.


For the long term, spectrum sharing is the best and most efficient strategy to maximize use of the limited resource of wireless spectrum available. Demand is currently massive and will only grow for wireless spectrum usage and applications. The United States needs DSS to maximize usage of wireless spectrum in real-time to be technologically ahead of global competitors and to improve access and services for business, governments and other organizations. Wireless spectrum should be viewed as and managed as a utility for the public good, which means prioritizing American businesses, people and the government on how it is managed. To do this, dynamic spectrum sharing is the only effective path forward.
