GPS, aviation interests and others continued to raise concerns to FCC in comments last week about operations of ultra- wideband (UWB) devices in GPS bands. But several companies suggested potential power limits and other restrictions that Commission could put in place to allow UWB operations to move forward. Aeronautical Radio Inc. (ARINC) and Air Transport Assn. of America (ATA) urged FCC to preclude unlicensed UWB operations. FCC sought comments on 5 test reports on potential of UWB devices to interfere with GPS and other licensed operations. Tests were conducted by NTIA, Dept. of Transportation through Stanford U., U. of Tex.-Austin Applied Research Labs and Johns Hopkins U. on behalf of Time Domain and Qualcomm. ATA and ARINC said studies pointed to “inability of unlicensed UWB devices as proposed to share spectrum, especially in restricted bands, with existing licensed services on a noninterference basis.” FCC “might consider” licensed deployment of UWB devices if future testing demonstrates sharing would work for certain devices, but ATA and ARINC still recommended UWB be barred from operating in restricted bands and generally below 5.5 GHz. In other comments: (1) Sprint PCS, citing Qualcomm report, recommended FCC prohibit UWB devices in PCS band. Sprint contended UWB devices would cause harmful interference to PCS CDMA networks even at stricter average power levels listed in notice of proposed rulemaking (NPRM). (2) Motorola suggested setting EIRP (effective isotropic radiated power) limit for UWB devices that would be 35 dB below current Part 15 limit for certain signals. (3) Lockheed Martin suggested need for “some form of regulatory mechanism for UWB devices” beyond current Part 15 limitations, saying that could be laid out in further NPRM. Among UWB proponents, Time Domain said different conclusions reached in studies largely resulted from “certain assumptions as to what should be deemed to constitute harmful interference.” Both NTIA and Stanford tests “assumed unrealistic operational scenarios and employed mathematical modeling to reach erroneous conclusions dependent on the flawed underlying assumptions.” Johns Hopkins study drew upon test results at U. of Tex. that covered both outdoor radiated testing in conjunction with indoor testing and extensive simulations. Time Domain said that meant that Johns Hopkins could provide FCC with several operational GPS measures of performance. Time Domain said all reports showed that with white noise-like signals, interactions with GPS signals were predictable “given the extensive body of knowledge” in that area. UWB implementation that Time Domain has developed is like white noise, company said. “When realistic propagation models and deployment scenarios are considered, the reports support the conclusion that UWB signals that appear much like white noise can be authorized at the Part 15 general limits without posing a risk of harmful interference to GPS,” Time Domain said. Sirius Satellite Radio took opposite view of test results, recommending FCC undertake “staged investigation” that focused on specific classes of UWB applications. Commission should define specific categories of UWB devices, including technical and operational characteristics, and quickly identify areas where more testing was needed, including effects of multiple UWB devices. Sirius said agency should develop specific proposed rules for each UWB device category, including its application, allowable average and peak power levels, allowable ranges of pulse characteristics in time domain, allowable spectrum masks.
FCC Chmn. Powell will be nominated for additional 5-year term, White House announced Fri. New term would begin July 2, 2002 and extend his tenure through June 30, 2007. Powell said he was “gratified by the confidence President Bush has indicated in my tenure.” He said extension “will provide a positive and helpful continuity to the important work that I, and the new Commissioners who will be taking office later this year, will be engaged in.” Senate must confirm new term.
NewSouth Communications urged FCC to deny joint petition by BellSouth, SBC and Verizon that seeks elimination of unbundling requirements for high-capacity loops and dedicated transport. NewSouth, which offers variety of competitive services, said Bell companies’ petition violated 3-year “quiet period” that FCC imposed on making changes in unbundling list. After Commission adopted list of unbundled network elements (UNEs) last year it said it wouldn’t reexamine list for 3 years to assure certainty, NewSouth said. “The three-year period was designed to give carriers time to implement [new interconnection] contracts and begin to realize their business plans,” NewSouth said in motion to dismiss filed April 24. “Not even a year has elapsed since some of the UNEs that the BOCs want to remove from the list first became available,” NewSouth said.
PanAmSat wants FCC to require early demonstration of compliance with operational and additional operational limits of companies before allowing spectrum sharing by NGSO FSS, GSO and terrestrial companies. Voicing strong opposition to portions of plan, PanAmSat filing argued against reconsideration petition from Skybridge as satellite companies weighed in with opinions on FCC decision on proposed spectrum sharing in 2 separate bands.
Comr. Ness, senior member of FCC, announced Thurs. she would be leaving agency by June 1 after 7 years. Ness, Democrat who was sworn in May 23, 1994, sought 2nd term after her 5-year term expired, but was stymied by Senate Commerce Committee Chmn. McCain’s refusal to confirm her. McCain said he didn’t approve of commissioners serving more than one term. Ness said she was making announcement now because “an orderly transition is best accomplished by announcing when my time with the Commission will end.” President Bush has announced names of 3 individuals he plans to nominate for Commission seats (CD April 9 p1) although there was some uncertainty about when new members would be confirmed. Their names haven’t been formally sent to Hill. Ness didn’t announce her plans.
BellSouth is expected to file with FCC as soon as today (April 27) for long distance entry in La., House Commerce Committee Chmn. Tauzin (R-La.) said Thurs. during Telecom Subcommittee markup of Bell data bill (HR-1542) (see separate story). “I hope they succeed,” he said.
Despite 14 dissenting votes, House Telecom Subcommittee cleared bill to deregulate Bell provision of data services (HR- 1254) Thurs., but not before members made several changes and extracted promises from bill’s sponsors to incorporate several more at full Commerce Committee markup. Sponsors, Committee Chmn. Tauzin (R-La.) and ranking Democrat Dingell (Mich.) did manage to fend off amendments that would have gutted bill, and both sides left claiming 6-hour markup was victory for measure’s long-term chances.
Sprint PCS appears to be in best position among major wireless carriers to comply with FCC’s Oct. 1 deadline for Enhanced 911 Phase 2 implementation, Pulver.com research report said. Report said carriers that were first to implement more specific location information requirements of Phase 2 were likely to exploit that position in advertising. It also said: (1) Verizon Wireless hadn’t asked for waiver of E911 Phase 2 requirements, so it didn’t appear to be off track for implementation. (2) It’s difficult to judge whether Cingular Wireless will meet deadline because carrier has raised possibility of waiver request but hasn’t asked for one. (3) “AT&T Wireless seems to have the least coherent location strategy.” Carrier has requested waiver on accuracy for Mobile Assisted Network Location System technology, report said. (4) Nextel’s initial deployment of Phase 2 is likely to start in Oct. 2002, one year behind original FCC schedule. Report said Sprint PCS appeared to be in best position because it provided detailed implementation information to FCC last Nov. and since then had made several supplier announcements. “Even if one of the major carriers will be ready on Oct. 1, 2001, to fully comply with the FCC E911 directive, the others would have no choice but move quickly and catch up,” Pulver report said.
Following complaints to FCC that Verizon overcharged competitors for electricity to operate colocated switching equipment, agency said it would investigate carrier’s new tariffs. Commission suspended for one day and set for investigation “lawfulness” of tariff revisions filed in FCC Tariff Nos. 1 and 11 by Bell Atlantic Telephone Companies (Verizon). Revisions in Tariff FCC No. 1 change monthly rate for DC power for physical colocation and establish new rate element for DC power for virtual colocation in Verizon’s south region. Tariff FCC No. 11 revised monthly rates for DC power for physical and virtual expanded interconnection agreements in Conn., New England, N.Y. Verizon said in ex parte letter to FCC April 13 it didn’t “simply pass along current from the electric grid” but added provisions for emergency backup power and upgraded buildings to handle added power. FCC investigation results from petitions filed by 12 Verizon competitors and ALTS that contended that Verizon had failed to provide adequate cost information on plant overhead and investments. Commission said petitions raised “substantial questions of lawfulness” that warranted its investigation.
Making fresh push for digital must-carry requirements during DTV transition, NAB, MSTV and ALTV jointly challenged FCC’s Jan. DTV order tentatively rejecting dual-carriage rules. In joint petition for reconsideration and clarification filed late Wed., broadcast groups called on Commission to impose dual-carriage requirements to spur DTV transition. They also urged agency to force cable operators to carry multiple streams of DTV video programming, not just single stream, and pressed FCC to provide greater safeguards against material degradation of DTV signals and require cable operators to use broadcasters’ program guide information in their set-top boxes and electronic programming guides.
