FCC OVERVIEW OF RECENT ACTIONS
by Bill Hurst
Broadband over Power Line
Carrier Current Systems, including Broadband over Power Line Systems (ET Docket No. 03-104) & Amendment of Part 15 Regarding New Requirements and Measurements for Access Broadband over Power Line (ET Docket No. 04-37), Notice of Proposed Rule Making
In order DA 04-1552, the deadline for filing reply comments in the Broadband over Power Line (BPL) proceeding was extended to June 22, 2004.
On February 23, 2004, the Commission released a Notice of Proposed Rulemaking (NPRM) in ET Docket Nos. 03-104 & 04-37, seeking comment on proposed rule changes to Part 15 of the Commission’s rules to promote the deployment of BPL systems. The NPRM was published in the Federal Register on March 17, 2004, establishing a comment date of May 3, 2004, and reply comment date of June 1, 2004.
NTIA Report 04-413, Potential Interference From Broadband Over Power Line (BPL) Systems To Federal Government Radio communications at 1.7-80 MHz, Phase 1 Study, Volume I, National Telecommunications & Information Administration, filed April 27, 2004. The report can be found at:
http://www.ntia.doc.gov/ntiahome/fccfilings/2004/bpl/FinalRe portAdobe/NTIA_BPL_Report_04-413_Volume_I.pdf.
DTV and Broadcast Receiver Standards
Unlicensed Operation in the TV Broadcast Bands (ET Docket No. 04-186); Additional Spectrum for Unlicensed Devices Below 900 MHz and in the 3 GHz Band (ET Docket No. 02380), Notice of Proposed Rule Making
In an initiative to increase the use of radio spectrum to provide greater service to the American public, the Commission has proposed to allow unlicensed devices to operate in the broadcast television spectrum at locations where the spectrum is not in use by television stations. In order to ensure that no interference is caused to TV stations and their viewers, the Commission proposed to require unlicensed devices to incorporate “smart radio” features to identify unused TV channels.
Interference Temperature
Establishment of Interference Temperature Metric to Quantify and Manage Interference and to Expand Available Unlicensed Operation in the Fixed, Mobile and Satellite Frequency Bands. (Adopted November 13, 2003)
The introduction of a new “interference temperature” model has the potential to improve radio spectrum management. Rather than assess interference based solely on transmitter operations, the interference temperature model introduced in the Commission’s Spectrum Policy Task Force Report takes into account the cumulative effects of all undesired radio frequency energy. The marketplace demands for spectrum require that the Commission explore new ways to use this resource more efficiently.
The Notice of Inquiry seeks comment on various technological factors and the process for managing the transition to a new interference temperature paradigm. The Notice of Proposed Rulemaking seeks comments on technical rules that would establish proper limits and procedures for assessing interference temperature. Moreover, the NPRM proposes to begin experimenting with the interference temperature approach on a limited basis in select frequency bands and recommends imposing restrictions on unlicensed devices that would include limiting the transmitter output power and requirements to use transmit power control (TPC) and dynamic frequency selection (DFS).
Spectrum Efficiency
Unlicensed Operation in the Band 3650-3700 MHz; Additional Spectrum for Unlicensed Devices Below 900 MHz and in the 3 GHz Band; Amendment of the Commission’s Rules with Regard to the 3650-3700 MHz Government Transfer Band, ET Docket Nos. 04-151, 02-380 and 98-237
The Commission issued a Notice of Proposed Rulemaking (Notice), that proposes amending the rules to maximize the efficient use of the 3650-3700 MHz band (“3650 MHz band”) and foster the introduction of new and advanced services. In broad terms, the central proposal of this Notice would allow unlicensed devices to operate in either all, or portions of, this radiofrequency (RF) band under flexible technical limitations with smart/cognitive features that should prevent interference to licensed satellite services. Specifically, it was proposed to allow these devices to operate with higher power than currently authorized under Part 15 of the Rules subject to cognitive technology safeguards.
Cognitive Radio / Software Defined Radio
Facilitating Opportunities for Flexible, Efficient, and Reliable Spectrum Use Employing Cognitive Radio Technologies (ET Docket No. 03-108); Authorization and Use of Software Defined Radios (ET Docket No. 00-47), Notice of Proposed Rulemaking and Order (Adopted December 17, 2003)
In light of the ever increasing demand for radio spectrum, and to facilitate new technologies and services and permit more intensive and efficient spectrum use, the FCC adopted a NPRM and Order that sets forth proposals and seeks comment on the use and applications for cognitive “smart” radio systems. The Commission’s proposals would provide additional technical and operational flexibility for service providers, particularly in rural and underserved areas, and also offer the potential for facilitating increased interoperability for public safety first responders.
U-NII Devices in the 5 GHz Band
Revision of Parts 2 and 15 of the Commission’s Rules to Permit Unlicensed National Information Infrastructure (U-NII) devices in the 5 GHz band, ET Docket No. 03-122 and RM10371, Report and Order (R&O)
Part 15 of the FCC Rules has been changed to make an additional 255 megahertz of spectrum available in the 5.470– 5.725 GHz band for unlicensed National Information Infrastructure (U-NII) devices, including Radio Local Area Networks (RLANs). This action will align the frequency bands used by U-NII devices in the United States with bands in other parts of the world, thus decreasing development and manufacturing costs for U.S. manufacturers by allowing for the same products to be used in most parts of the world.
In order to allow the immediate implementation of U-NII devices in accordance with the rules adopted in the Order, an interim test procedure drafted by the 5 GHz Project Team may be used to obtain equipment certifications for U-NII devices. This procedure may need to be modified as equipment is developed and as the testing methodologies are refined. Therefore, consistent with existing practice, the FCC Laboratory may issue updated measurement procedures in the future. The interim test procedure is set forth in Appendix C of the Order.

Don Heirman Chair
Projects turned over to C63 for processing
Five subcommittee projects have been completed and turned over to C63 Main Committee for processing. The projects are: C63.2 Standard on emission measurement instrumentation C63.5 Standard for antenna calibration C63.15 Recommended Practice on immunity measurement
methods C63.22 Guide for Automated EMI measurements C63.23 Guide for measurement uncertainty estimation
Project 1-13.2 C63.4 Site Acceptability Above 1 GHz
This project is in support of C63’s harmonizing effort with CISPR Subcommittee A to specify minimum performance criteria for existing antenna products on the market including antenna pattern. An investigation was initiated to consider using time domain techniques to view site imperfection. Based on the investigations, a determination will be made on a reasonable test facility pass/fail criteria for validating the facility
Project 1-15.7 C63.4 Fully Absorber Lined Room (FAR)
A draft test plan has been prepared to assess correlation between FARs and OATs or semi-anechoic chambers. The specific test “artifact” is a floor standing frame with emissions emanating near and above the base. Project 1-15.9 Maintenance of Revision to C63.4-2003
The current focus of this project is to address the following specific issues:
*Site validation and measurement procedures > 1 GHz.
*GTEM validation and measurement procedures for intentional radiators and for frequencies >1 GHz and harmonization with IEC 61000-4-20 and related TIA standards.
*Stabilization of emissions from cables leaving the test site
(e.g. through ferrite channel or other means).
*Add to Figure 2 (LISN) a tabular list in addition to the graph.
*General harmonization with CISPR 22.
*Clarify paragraph 11.1.3 e) and f) on exercise of displays.
*In section 12.2.1 replace “5 V peak-to-peak VITS signal supplied through the video input port.” With “the highest input voltage where video is still processed or present, or visible on the TV screen without error, should be recorded and tested.”
*LISN calibration procedures.
*Definition of cable loss as a function of temperature.
Also, working group chair Stephen Berger advised that several issues related to GTEMs will be addressed:
*Accommodating the need for testing products above 1 GHz which is accommodated in part by GTEMs.
*A round robin test of an artifact in GTEMs is underway by a GTEM user group to provide technical inputs to the extension of the application of GTEMs to be used above 1 GHz in C63.4.
*Should this work above 1 GHz lead to an independent test method or one that should be correlated with another test facility such as an OATS
A draft amendment to C63.4 is anticipated by the year-end with a potential publication in 2006.
Project 1-15.10 C63.2 and C63.4 Use of Spectrum Analyzers for Emissions Testing
Based on an approved PINS, a working group was formed to establish how to use spectrum analyzers in making emission tests.
2004 Working Group Chairs were approved:

Dan Hoolihan, Chair
The April 28, 2004 SC-8 meeting was held at the FCC Laboratory in Columbia Maryland with 15 members and 9 guests present. A number of status reports were received which are summarized below:
WG#1 Second Edition of C63.18 (Jeff Silberberg Chair): This Working Group now consists of the following members – Jeff Silberberg, Chair; Don Heirman; Herb Mertel; Joe Morrissey; and Don Witters. At the October 2003 meetings of C63, SC5 agreed to help SC8/WG1 complete the second edition of C63.18 to facilitate harmonization between it and the SC5 ad hoc immunity testing recommended practice. SC5 members who agreed to participate are as follows: Ed Hare, Chair SC5; Joe Morrissey, Secretary SC5 (also member SC8/WG1); Jon Casamento; Chrysanthos Chrysanthou; Don Heirman (also member SC8/WG1); Wayne Hunter; Victor Kuczynski; Herb Mertel (also member SC8/WG1); and Bill Scrivner. The combined list of SC8/WG1 and SC5 members will hereafter be referred to as the C63.18 JWG.
At the October 2003 meetings of C63, Ed Hare expressed concern about one of the major changes being implemented in the second edition of C63.18, starting testing at a distance that achieves approximately 20 V/m, because he had seen damage occur to a consumer product when a radio was keyed nearby. Jeff Silberberg consulted the following references and found no reports of damage during ad hoc testing:
*Morrissey: 800-900 and 1800-1900 MHz (analogue & digital) cell phones and EMI with medical devices -Health Physics (2002) 82:45-51
*MDA: 28-470 MHz (CW) radios, 8-900 & 18-1900 MHz (analogue & GSM), cell phones and EMI with medical devices - MDA Bulletin (MDA DB 9702), March 1997
*Sibakov: 400 MHz (NMT), 800 MHz (NMT & GSM), and 1800 MHz (GSM) cell phones and EMI with medical devices
- VTT Technical Bulletin (ESPOO 1998)
*Tri: Cell phones (analogue & digital) and EMI with medical devices - Mayo Clinic Procedings (2001) 76:11-15
*Hietanen: 400 MHz (TETRA) and 900 & 1800 MHz (NMT & GSM) cell phone exposure and EMI with medical devices - Health Physics (2000) 79(suppl):S77-S84. No damage reported, using up to 3 W peak at d = 5 cm.
*Hanada: 1.9 GHz (PHS) cell phone exposure and EMI with medical devices - IEEE Trans Electromagnetic Compatibility (2000) 42:470-475. No damage reported with 8 W transmitter at d = 1 cm.
*Rice: 2450 MHz (LAN) transmitter exposure and EMI with medical devices - J. Clin Engineering (Sep/Oct 2000) 260264. No damage reported at field strengths of up to approximately 18 V/m.
*Barbaro: 450 MHz (CW-radios) and 900 & 1800 MHz (GSM) cell phone exposure and EMI with ventilators -Biomedical Instrumentation & Tech (2000) 34:361-369
*Turcott & Witters, 400 MHz (CW-radio), 800 MHz (analogue cell phone) & 1900 MHz (PCS cell phone) exposure and EMI with medical devices – Biomed Instrum Technol (1998) 32:241-52
In addition, Jeff Silberberg contacted several researchers who had performed extensive ad hoc immunity testing of medical devices, including Drs. Tan and Segal in Canada. Dr. Tan had not seen damage, even during close in / contact testing. Dr. Segal had seen damage only once, “from a 4-watt walkietalkie operating at a 10 cm distance, which puts the E field well over 20 V/m.”
From this research, it can be concluded that there is low risk in implementing this change to the test procedure. Draft 4.2 was circulated to members of the C63.18 JWG in November 2003. Jeff Silberberg is in the process of incorporating comments received and will discuss some of the issues raised with the JWG.
WG#2 C63.21 (Howard Bassen, Chair): Howard Bassen presented a power-point proposal on whether ANSI C63-SC8 should develop a horizontal standard for radiated susceptibility and immunity of medical implants. Existing standards for use in this area include:
*ANSI/AAMI PC69:2000 (which is looking to extend lower frequency range to below 30 MHz. It uses salinity of 0.18 for test, human body is 0.9; however, pacemaker won’t work in phantom with 0.9 salinity.)
*ASTM F 2182 – (gel closer to 0.9 salinity than AAMI standard)
*ETSI EN 302 195-1 – (30 cm phantom)
*IEC 60601-1 – (medical implants outside of scope)
*FCC Docket 03-137 -NPRM will allow model or measurement, no low power exclusion.
After significant discussion, the subcommittee agreed to go forward with the proposal.
WG#3 C63.19 (Steve Berger, Chair): Steven Berger reported the revision of C63.19 that is out for recirculation ballot was approved, but 4 negative votes were received, including one from the FDA (still not resolved). It is expected that the comments will be resolved by April 30, 2004. It is expected the standard-revision will have to be circulated a second time.
IEC SC62A Maintenance Team 23 : Jeff Silberberg reported on progress with regard to Amendment 1 of 60601-1-2. The Final Draft International Standard (FDIS) will be circulated in about 2 months.
AAMI/EMC Committee Report :The next meeting will be held in Boston on June 8, 2004. The main topic of discussion will be revising Technical Information Report 18.
FDA Report: Donald Witters from the FDA reported manufacturers want more coordination between FDA and FCC with respect to the interaction between wireless devices and medical devices. The FDA has been working with the FAA on how to handle medical devices and metal detectors (also anti-theft systems on a lesser level) as well as Industry Canada. The FDA is also working with the US Army on use of pda’s. The FDA is also working with manufacturers on warnings to allow users to be aware of interference control measures with respect to wireless devices and medical devices. The FDA continues to follow closely the hearing aid interference (C63.19) issues.
Jon Casamento announced they did a study on insulated lead vs. bare lead transmission sources on an implant (boat transmitter vs. cell phone). Howard Bassen will distribute the study paper to the committee chairman once it is cleared.
Mobile Healthcare Alliance (MoHCA) Report: Joe Morrissey/Jeff Silberberg/Donald Witters said there is a white paper coming out. Joe Morrissey will send update to the committee chairman for distribution.
Jon Casamento submitted a PINS-C to develop a test method similar to IEC 14708-1 Part 27. This is a test generating a field of 150 A/m from 0 Hz to 150 kHz and falling off at 1/f up to 30 MHz (simulating anti-theft system).
The next SC-8 meeting will be held on October 27, 2004 in Austin, Texas.
