AGENCY:

Federal Communications Commission.

ACTION:

Proposed rule.

SUMMARY:

In this document, the Commission seeks to promote and facilitate wireless innovation to ensure that the promise of dynamic spectrum access technologies can be fully realized and applied across more of the radio spectrum. A dynamic sharing approach would, for example, allow devices to identify and use slices of spectrum that are available in a particular location for a limited time—from as little as few seconds to as much as several days. Specifically, the Commission seeks comment on the variety of ways in which dynamic spectrum access radios and techniques can promote more intensive and efficient use of the radio spectrum, and the potential that these technological innovations have for enabling more effective management of spectrum.

DATES:

Comments must be filed on or before February 28, 2011, and reply comments must be filed on or before March 28, 2011.

Summary of Notice of Inquiry

1. In the Notice of Inquiry (NOI), the Commission explores the current state of development of dynamic spectrum access technologies, including the technical developments that affect the design and operation of dynamic radios. In particular, it examines the development of spectrum sensing and other dynamic spectrum sharing capabilities and techniques. Next it explores ways in which it can help promote the development of these technologies for use on both a licensed and an unlicensed basis. The Commission inquires whether there are additional steps it should take to improve its “Spectrum Dashboard,” a Web-based access tool that enables users to determine how spectrum is being used, who holds spectrum licenses around the country, and what spectrum is available in a particular geographic area. In addition, the Commission seeks comment on how spectrum used through secondary market arrangements could employ dynamic spectrum access radios and techniques. It also seeks comment on establishment of dynamic access radio test beds and on spectrum bands that might be suitable for dynamic spectrum access. Finally, the Commission examines whether the database access model applicable to unlicensed Television Band Devices might be deployed in other spectrum bands.

2. As a general matter, dynamic spectrum access radios, as well as the new spectrum management techniques that they can enable, hold great promise to increase productive use of spectrum as the Commission seeks to use the nation's available spectrum resources more intensively and efficiently. With data traffic on mobile wireless networks estimated to grow by a factor of thirty-five between 2009 and 2014, there is a critical need for increased efficiency in use of spectrum, as well as the need for additional spectrum, not only for mobile wireless networks, but also for a wide variety of RF-based applications and services. Ensuring that the Commission can take advantage of these improved efficiencies will be critical as it addresses this spectrum challenge, and can lead to increased spectrum value that spurs additional investment and innovation that can benefit American consumers. The Commission seeks to expand the environment in which these advanced technologies and techniques can be developed and improved, and then can be applied across more radio spectrum. Thus, it seeks information on these dynamic technologies and on what additional steps the Commission can and should take to encourage, promote, and incentivize their development and use in both unlicensed and licensed spectrum.

3. The Commission believes that there are opportunities for use of dynamic spectrum access techniques under both licensed and unlicensed regulatory approaches. Each approach has its benefits and limitations in the context of dynamic spectrum access techniques. It also observes that, as spectrum users seek to make the best and most efficient use of the available spectrum resource, they are increasingly using a combination of unlicensed networks and dedicated licensed networks employing advanced radio devices to meet their spectrum needs. The Commission's objective is to identify how to make the most efficient use of spectrum to help meet the demand for wireless broadband services, as well as many other applications, under both licensed and unlicensed regulatory approaches.

4. Much work is being done to advance dynamic radio technologies, and the Commission believes that this work has already enabled more efficient use of the spectrum resource. However, this work is still in its early stages, and far more efficient spectrum use may be possible in the future. For this to happen, not only must advances continue to be made in the areas of sensing technology, usage algorithms, and cognitive abilities, but regulatory models may need to change. The Commission therefore inquires as to what it can do to best facilitate the use of dynamic radio technology, both from a technical and non-technical perspective.

5. Pursuant to sections 4(i), 301, and 303 of the Communications Act of 1934, as amended, 47 U.S.C. 154(i), 301, and 303, this Notice of Inquiry is adopted.
