Summary of Public Notice

1. The Office of Engineering and Technology (OET) seeks to refresh the record on issues raised in petitions for reconsideration of the Report and Order, 69 FR 2677, January 20, 2004, in this proceeding. The petitions sought reconsideration and clarification, in part, of the equipment authorization requirements for Unlicensed National Information Infrastructure (U-NII) devices employing dynamic frequency selection (DFS). The International Telecommunication Advisory Committee-Radiocommunication (ITAC-R) Government/Industry Project Team (Project Team) recently reached consensus on revised compliance and measurement procedures for DFS, and the National Telecommunications and Information Administration (NTIA) has presented these recommendations to the Commission. NTIA notes that the revised procedures represent the Federal Government's requirements for compliance measurement procedures for U-NII devices employing DFS and include modified definitions, new response requirements, and reporting requirements compared to previous versions of the procedures.

2. On November 12, 2003, the Commission adopted a Report and Order, in this proceeding, which amended part 15 of the rules to make an additional 255 megahertz of spectrum available in the 5.470-5.725 GHz band for U-NII devices, including Radio Local Area Networks (RLANs). In addition to making more spectrum available for use by U-NII devices, the Commission took steps to minimize the potential for these devices to cause interference to existing radiofrequency operations. Specifically, the Commission adopted requirements for U-NII devices in the 5.250-5.350 GHz and 5.470-5.725 GHz bands to employ Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC). The Commission codified requirements for these U-NII devices in part 15, Subpart E of its rules (47 CFR 15.401 et seq.).

3. In the Report and Order, the Commission also provided an interim measurement procedure to be used by the Commission and others in determining whether U-NII devices comply with the rules. The Commission stated that the provisions of this test procedure would need to be modified as equipment was developed and as testing methodologies were refined. The Commission also stated that the OET Laboratory may issue updated measurement procedures in the future. The Project Team has worked since the release of the Report and Order to develop new measurement procedures for performing DFS compliance measurement tests for U-NII equipment operating in the 5250-5350 MHz and 5470-5725 MHz bands.

4. Globespan Virata (Globespan), Wi-Fi Alliance, and Extreme Networks filed petitions seeking clarification or reconsideration of various aspects of the rules adopted in the Report and Order. Globespan requests that the Commission revise the rules to state that U-NII devices are not required to detect and avoid frequency hopping radar signals. Globespan further requests that if it was the intent of the Commission to include frequency hopping radars in the DFS requirements, the Commission should specify a measurement procedure for this requirement. Wi-Fi Alliance seeks clarification, in part, of the channel availability check time requirement in section 15.407(h)(2)(ii). Finally, Extreme Networks seeks clarification of the definition of a U-NII central controller that must include DFS capability.

5. OET notes that these petitions for reconsideration raise issues regarding DFS compliance and measurement procedures that are addressed in the Project Team's revised procedures. Therefore, in order to refresh the record, Start Printed Page 26006we seek additional comment on the DFS issues raised in the petitions filed by Globespan, Wi-Fi Alliance, and Extreme Networks and, in particular, how these issues are addressed by the Project Team's revised compliance and measurement procedures and the Commission's rules.
