We see no benefits in requiring halting the operation of GPRs and wall imaging systems that already are in the hands of the public and may have been used for several years without causing harmful interference. Accordingly, we are providing a blanket waiver of the Part 15 regulations, with the exception of 47 C.F.R. §§ 15.5(a)-(c), 15.11, 15.29, 15.521(a) and 15.525, for existing GPRs and wall imaging systems. This waiver applies only to those entities that are eligible to operate GPRs and wall imaging systems, as described later in this order under the discussion on ``Operating Restrictions,'' and that have registered their equipment with us, following the procedures shown below.

  • Ruling was filed on behalf of twenty-three companies and associations (the ``requesting parties''). The requesting parties ask the Commission to issue a declaratory ruling that all emissions associated with digital circuitry used to generate ultra-wideband (UWB) emissions are required to meet the radiated emission limits provided in Subpart F of Part 15 of the Commission's rules for UWB transmitters. Section 15.521(c) of the Commission's rules states that emissions from digital circuitry contained within a UWB transmitter are subject to the limits specified in Section 15.209 if those emissions are not intended to be radiated from the transmitter's antenna. The requesting parties assert that the language in Section 15.521(c) is ambiguous because the regulation identifies any emission that is not intended to

MBOA-SIG argues that their modulation technique is not frequency hopping and that the Commission's reasons for requiring measurements to be performed with the hopping stopped was to determine that the system met the minimum bandwidth requirement for consideration as a UWB device. MBOA-SIG also argues that the requirement in Section 15.521(d) of the rules to disable output gating was not intended to apply to MB-OFDM systems and that MB-OFDM systems pose no greater threat of harmful interference than pulsed UWB devices.

  • pulse position modulation. DISCUSSION It is a well established principle that the Commission will waive its rules if it determines, after careful consideration, that such a grant would serve the public interest without undermining the policy which the rule in question is intended to serve. We find that a waiver of the emission limits in 47 C.F.R. §§ 15.511 and 15.521(g) is consistent with that principle. The CWCEC QUPID UWB surveillance system will enhance the protection of installations that are vital to the public well-being, facilitating homeland security efforts. In view of these benefits, we find that the ability to use this equipment is in the public interest. We concur with CWCEC that its QUPID UWB surveillance system provides unique intrusion

  • relevant FCC rules for UWB equipment. Although some narrow band emissions were detected in the 960-3100 MHz band, these emissions are attributable to the associated digital circuitry contained within the UWB device, are not radiated by the UWB antenna, and are compliant with the Part 15 general emission limits in 47 C.F.R. § 15.209, as stipulated under 47 C.F.R. § 15.521(c). Our investigation identified the narrowband emissions in the 960 to 3100 MHz band as harmonics of the 19.2 MHz oscillator contained in the digital module portion of Time Domain's UWB device. To confirm that the emissions in the 960 to 3100 MHz band are not intended to be radiated by the device's antenna, the emissions levels were measured with the

  • While these filings are being addressed in separate actions, they demonstrate that we should clarify the regulation regarding limits on emissions produced by digital circuitry used within UWB devices. A precise description of the digital emission limits was provided in the R&O. However, the wording contained within the rules is not as clear. Accordingly, we are amending 47 C.F.R. § 15.521(c) to more closely comport with the text of the R&O. As this change to the regulations is interpretative and only clarifies a standard that already has been adopted, prior notice and public comment are unnecessary. Additional filings.

MBOA-SIG states that it is not clear if the UWB test procedures, which it claims were designed for pulse-based systems, apply to MB-OFDM systems. Consequently, it seeks a waiver of the measurement procedures, including the pulse gating procedures in 47 C.F.R. § 15.521(d), to the extent that they apply to MB-OFDM systems. The MBOA-SIG requests that this waiver apply only to a specific MB-OFDM architecture consisting of three non-overlapping operating bands. Transmitters using this MB-OFDM format would operate under the provisions for indoor and handheld UWB devices.

MBOA-SIG also requested a waiver of the measurement procedure in 47 C.F.R. § 15.521(d), as adopted in the First R&O, for pulse gated systems to the extent that this rule applied to MB-OFDM systems. Freescale Semiconductor, Inc.
