Summary of the Notice of Proposed Rule Making
1. The Notice of Proposed Rule Making (NPRM) responds to a Notice of Inquiry (NOI) in this proceeding, 65 FR 17246, March 31, 2000. The NOI sought comments on a number of issues related to software defined radios. These issues included the current state of technology, how this technology could facilitate interoperability between radio services, how it could improve spectrum efficiency and spectrum sharing, and what changes may be required in the equipment approval process.
2. The NPRM proposes to amend part 2 of our rules to streamline the equipment authorization procedures for software defined radios (SDR). Specifically, we propose to define software defined radios as a new class of equipment with equipment authorization rules that reflect the additional flexibility incorporated into such radios. We propose to permit equipment manufacturers to make changes in the frequency, power and modulation of such radios without the need to file a new equipment authorization application with the Commission. We also propose to permit electronic labeling so that a third party may modify a radio's technical parameters without having to return to the manufacturer for re-labeling. We believe that these changes will facilitate the deployment and use of this new promising technology. The frequency and technology agility of software defined radios could increase the use of presently underutilized frequency bands.
3. We recognize that there is no universally accepted definition of a software defined radio. We stated in the NOI that many radios now contain microprocessor technology that can control functions such as frequency and power. Until recently, these functions were controlled by firmware installed at the factory and are not readily changeable by the user. To facilitate the development of these types of radios, we propose a new, more flexible equipment approval process. We propose the following definition of software defined radio to delineate what types of devices fall within the proposed new rules.
A software defined radio is a radio that includes a transmitter in which the operating parameters of the transmitter, including the frequency range, modulation type or maximum radiated or conducted output power can be altered by making a change in software without making any hardware changes.
We seek comments on the sufficiency of this definition or any alternative definitions that may be more appropriate.
4. We believe that some relaxation of the current equipment authorization procedures is appropriate. Thus, we propose to develop a more streamlined authorization procedure for changes to software defined radios. Specifically, we propose that changes in the frequency, power, and modulation type of a software defined radio could be authorized as a new class of permissive change, which we propose to designate as Class III. This would eliminate the need to re-label equipment when new software is loaded and would streamline the filing procedure for changes to approved devices. Software changes that do not affect these operating parameters would be treated as Class I permissive changes, so no filing would be required for them. The applicant for a Class III change would submit test data showing that the equipment complies with the applicable requirements for the service(s) or rule parts under which it will operate with the new software loaded. The applicant would also have to demonstrate compliance with the applicable RF exposure requirements. The Commission would notify the applicant by letter when a permissive change is granted. Once a Class III permissive change has been granted for new software that affects the operating parameters, the software could be loaded into units in the field. The record in the Commission's database for each authorized device would show the approved frequency range(s), power and modulation type(s) as it does now. Additional frequency ranges or other new technical parameters would be added to the database record for an authorization when a permissive change is granted.
5. We propose that the original certification application must identify the equipment as a software defined radio, and that only the grantee of the authorization for a software defined radio may file for a Class III permissive change. We also propose that Class III permissive changes may only be made to equipment in which no hardware changes have been made from the originally approved device to eliminate ambiguity about which hardware and software combinations have been approved. We recognize that while the filing procedure for permissive changes is streamlined, Commission staff is still required to perform a technical review of the new test data for compliance with the rules. Therefore, we propose to apply the filing fee for certification of transmitters used in licensed services to the new Class III permissive changes to reflect the staff time required to process these changes.
6. We seek comments on whether a new class of permissive change should be established, the type of information that should be submitted to show compliance with the service rules and Start Printed Page 342RF exposure requirements, the appropriate filing fee for such changes, whether parties other than the grantee should be allowed to file for permissive changes.
7. In addition, we seek comments on whether this new class of permissive change should be limited to software changes only, whether we should allow a combination of hardware and software permissive changes in a single device, whether there is a need for applicants to submit a copy of radio software to the Commission, and whether we should place limits on the number of hardware and software combinations under a single approval. We further seek comment on the benefits of the proposed new permissive change compared to the existing requirement for new identification numbers if we allow the alternative labeling method described in the NPRM.
8. We believe that a major benefit of software defined radios will be the ability of manufacturers to produce radios intended to be programmed by third parties with unique or specialized application software. To help realize this benefit, we are proposing an option for software defined radios to be equipped with an “electronic label” to display the FCC identification number by means of a light emitting diode (LED) display, a liquid crystal display (LCD) screen or other similar method. This would provide a method to re-label equipment in the field if a new approval were obtained by a third party for a previously approved device. The information would have to be readily accessible in a manner that allows it to be easily viewed. We request comments on this proposal, including whether there is a need for this capability, the type of display that should be required, the means that should be required for accessing the information, and the information to be displayed. We recognize that not all transmitters that are potentially programmable would normally have an LED, LCD or similar display, so we also request comments on whether manufacturers would need to add such displays to take advantage of the electronic labeling capability. We also seek comments on whether electronic labeling should be permitted for other types of equipment besides software defined radios.
9. We tentatively conclude that a means will be necessary to avoid unauthorized modifications to software that could affect the compliance of a radio. While we believe we may eventually have to adopt rules addressing software authentication, we believe it would be premature for us to propose specific requirements for authentication while standards are still under development. Accordingly, at this time we are proposing a more general requirement that manufacturers must take steps to ensure that only software that is part of a hardware/software combination approved by the Commission or a TCB can be loaded into a radio. The software must not allow the user to operate the radio with frequencies, output power, modulation types or other parameters outside of those that were approved. Manufacturers may use authentication or any other means to meet these requirements, and must describe the methods in their application for equipment authorization. The grantee of an equipment authorization is responsible for ensuring the integrity of the authentication or security system. Failure to do so could result in the revocation of the authorization. We believe that this proposal would protect against harmful interference and safety hazards from software defined radios without interfering with the development of the technology. We request comments on this proposal, including whether it could impede legitimate third party software developers from developing applications for software defined radios. We also seek comments on the types of authentication standards that are likely to be developed, whether the standards should be industry developed or government sponsored, whether the standards should be voluntary or mandatory, and whether these standards would be applicable to all types of software defined radio equipment.
10. We believe that the rule changes we are proposing will allow manufacturers greater flexibility in obtaining approval for software defined radios and will facilitate deployment of this equipment to consumers. We further believe that the proposed requirements for authentication of software will provide a safeguard against unauthorized modifications of approved equipment. However, we recognize that a non-compliant software defined radio has the potential to interfere with other radio services due to its potential to operate in multiple frequency bands. Therefore, we request comments on whether we should enhance our enforcement capabilities and what particular changes we should make. For example, should we establish requirements prohibiting manufacturers or grantees from knowingly marketing software that would cause a software defined radio to operate in violation of the Commission's rules? We request comments on this and any other matters that may be pertinent to software defined radios.
Initial Regulatory Flexibility Analysis
11. As required by the Regulatory Flexibility Act (RFA), the Commission has prepared this present Initial Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on small entities by the policies and rules proposed in this Notice of Proposed Rule Making (NPRM). Written public comments are requested on this IRFA. Comments must be identified as responses to the IRFA and must be filed by the deadlines for comments provided in paragraph 38 of this NPRM. The Commission will send a copy of this NPRM, including this IRFA, to the Chief Counsel for Advocacy of the Small Business Administration (SBA). In addition, the NPRM and IRFA (or summaries thereof) will be published in the Federal Register.
A. Need for, and Objectives of, the Proposed Rules
12. A number of parties are currently developing software defined radio technology. In a software defined radio, functions that were carried out by hardware in the past are performed by software. This means that the operating parameters of the radio, such as the frequency and type of modulation, could be readily changed in the field. The current rules do not prohibit software programmable radios. However, they require a new approval and a new identification number on a permanently affixed label when changes to the frequency, power or type of modulation are made. The requirement to re-label equipment in the field when a change is made could tend to discourage deployment of software defined radios to consumers. Therefore, we are proposing changes to our equipment authorization rules to facilitate such deployment. These changes would streamline the equipment approval process for software defined radios and would reduce the filing burden on applicants.
B. Legal Basis
13. The proposed action is authorized under Sections 4(i), 301, 302, 303(e), 303(f), 303(r), 304 and 307 of the Communications Act of 1934, as Start Printed Page 343amended, 47 U.S.C. 154(i), 301, 302, 303(e), 303(f), 303(r), 304 and 307.
C. Description and Estimate of the Number of Small Entities to Which the Proposed Rules Will Apply
14. The RFA directs agencies to provide a description of and, where feasible, an estimate of the number of small entities that may be affected by the proposed rules, herein adopted. The RFA generally defines the term “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction.”  In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act. A small business concern is one which: (1) Is independently owned and operated; (2) is not dominant in its field of operation; and (3) satisfies any additional criteria established by the SBA.
15. The Commission has not developed a definition of small entities applicable to Radio Frequency Equipment Manufacturers (RF Manufacturers). Therefore, the applicable definition of small entity is the definition under the SBA rules applicable to manufacturers of “Radio and Television Broadcasting and Communications Equipment.” According to the SBA's regulation, an RF manufacturer must have 750 or fewer employees in order to qualify as a small business. Census Bureau data indicates that there are 858 companies in the United States that manufacture radio and television broadcasting and communications equipment, and that 778 of these firms have fewer than 750 employees and would be classified as small entities. We believe that many of the companies that manufacture RF equipment may qualify as small entities.
D. Description of Projected Reporting, Recordkeeping, and Other Compliance Requirements
16. We propose to establish a new class of “permissive change” for software defined radios when changes are made to the software that affect the frequency, power or type of modulation. This class of change would require the manufacturer to submit a description of the software changes to the FCC or a designated Telecommunications Certification Body (TCB). The manufacturer would also be required to submit test data showing that the radio complies with the technical standards in our rules with the new software loaded. The new software could not be loaded into radios until the FCC or TCB notifies the manufacturer that the changes are acceptable. The original FCC identification number for the equipment could continue to be used, so no re-labeling would be required.
17. We also proposed to allow an “electronic label” to be used on software defined radio transmitters as an alternative to the permanently affixed label the rules currently require. The equipment would display the FCC identification number by means of a liquid crystal display or similar screen.
18. We further proposed that manufacturers must take steps to ensure that only software that has been approved by the FCC or a TCB can be loaded into a transmitter. The software must not allow the user to operate the transmitter with frequencies, output power, modulation types or other parameters outside of those that were approved. Manufacturers may use authentication codes or any other means to meet these requirements, and must describe the methods in their application for equipment authorization.
E. Steps Taken To Minimize Significant Economic Impact on Small Entities, and Significant Alternatives Considered
19. The RFA requires an agency to describe any significant alternatives that it has considered in reaching its proposed approach, which may include the following four alternatives (among others): (1) The establishment of differing compliance or reporting requirements or timetables that take into account the resources available to small entities; (2) the clarification, consolidation, or simplification of compliance or reporting requirements under the rule for small entities; (3) the use of performance, rather than design, standards; and (4) an exemption from coverage of the rule, or any part thereof, for small entities.
20. We considered three alternatives to streamline the requirements for software defined radios, which will reduce the burden on small entities.
(a) The first alternative, which we proposed in the NPRM, would permit changes in the frequency, power, and modulation type of a software defined radio to be authorized as a new class of permissive change. A new FCC identification number is not required for permissive changes, so there would be no need to re-label equipment when new software that changes the operating parameters is loaded. Permissive changes only require filing test data showing that the equipment complies with the applicable requirements in the rules with the new software. A complete application with exhibits including block diagrams, schematic diagrams, photographs and the users' manual is not required. Only the party holding the grant of equipment authorization my file for permissive changes.
(b) The second alternative, which we proposed as an option in the NPRM, is to allow the FCC identification number to be displayed electronically rather than on a permanently affixed label. A major benefit of software defined radios will be the ability of manufacturers to produce radios intended to be programmed by third parties, including small entities, which could develop unique or specialized application software. The “electronic label” would help realize this benefit. It would provide a method to re-label equipment in the field without having to change a physical label if a new approval were obtained by a third party for a previously approved device.
(c) The third alternative we considered is to allow software changes to be approved under the Declaration of Conformity (DoC) procedure. DoC is a self-approval procedure in which the manufacturer has the equipment tested for compliance at an accredited laboratory. Once the equipment has been found to comply, it may be marketed without any approval from the FCC or a TCB. Although this alternative would reduce the burden on small entities, we declined to propose it because we believe that most radio transmitters require a higher level of oversight to ensure that they comply with the rules to prevent interference and protect users from excessive RF radiation. Certain radio transmitters are already permitted to be self-approved, and we are not proposing any change in the authorization requirements for them. Start Printed Page 344
