  • -75.3 47 C.F.R.§15.209 Emission Limit (dBm/MHz) -41.3 Additional Attenuation Required (dB) 34.0 Thus, the average emission limit applicable indoor UWB devices in the 960-1610 MHz frequency range is an equivalent isotropic radiated power (EIRP) of -75.3 dBm/MHz. This limit is applicable in the 960-1610 MHz band to the following UWB applications: Indoor UWB Applications (Section 15.517), Handheld UWB Applications (Section 15.519), and Vehicular Radar Systems (Section 15.515 ). In this measurement effort, the GPS interference susceptibility threshold, -117.5 dBm/MHz, is used as a basis for comparison in both the ambient and spurious emissions measurements. A display line is used to depict this limit on the spectrum analyzer plots included in this report. For the ambient emission measurements, the display line at

  • 02-48, in the above entitled proceeding. Subsequent to the release of this Order, we noted that paragraphs (e) through (g) of Section 15.517 were inadvertently mislabeled, resulting in an incorrect paragraph reference in paragraph (e) of Section 15.517. We also noted that there was a typographical error in the tables contained in paragraph 67 of the text and in Section 15.519(c) of the rules in Appendix D. The discussion contained in paragraphs 183, 193, 199 and 224 of the Order clearly indicates that the frequency ranges contained in the tables should have been specified as 1610-1990 MHz and as 1990-3100 MHz. To correct these errors, we are redesignating paragraphs (e) through (g) of Section 15.517 as paragraphs (d) through (f), and

  • aeronautical antennas at airports. Indeed, the majority of interference problems reported by NTIA in its analyses of interference to non-GPS systems concerned outdoor systems and especially outdoor systems operating at an elevation of 30 meters. These provisions will ensure that even nearby RF devices, including devices that also may operate indoors, will not receive interference. Hand Held UWB Systems. Section 15.519 of Appendix D contains the provisions for miscellaneous UWB devices that are primarily hand held and intended to operate in a peer-to-peer mode without restriction on location. Operation among peer-to-peer devices is expected to be a strong driver for the development of UWB technology. We recognize that the greatest concerns of interference in the record were centered about the potential

  • press package along with the News Release of February 14, 2002, announcing the adoption of the R&O unintentionally did not reflect the emission limits below 960 MHz. The UWB emission limits below 960 MHz are the Part 15 general emission limits contained in 47 C.F.R. § 15.209, as correctly stated in 47 C.F.R. §§ 15.509(d), 15.511(d), 15.513(d), 15.515(d), 15.517(c), and 15.519(c). Accordingly, no change to our regulations is required to implement this clarification. Vehicular radar systems in the 22-29 GHz band The UWB regulations permit the operation of vehicular radar systems in the 22-29 GHz band. UWB vehicular radar systems are required to operate at all times with a minimum 500 MHz bandwidth and may employ any modulation technique that results

  • Measurements made in this manner shall be repeated over multiple sweeps with the analyzer set for maximum hold until the amplitude stabilizes. Section 15.521 is amended by revising paragraph (d), to read as follows: Section 15.521 Technical requirements applicable to all UWB devices. * * * * * (d) Within the tables in Sections 15.509, 15.511, 15.513, 15.515, 15.517, and 15.519, the tighter emission limit applies at the band edges. Radiated emission levels at and below 960 MHz are based on measurements employing a CISPR quasi-peak detector. Radiated emission levels above 960 MHz are based on RMS average measurements over a 1 MHz resolution bandwidth. The RMS average measurement is based on the use of a spectrum analyzer with a resolution

  • from such systems shall be measured in their normal operating mode. These waivers do not apply to systems that employ swept frequency modulation. Further, UWB transmitters certified under these waiver provisions also shall comply with the following provisions: Operation under the provisions of this waiver shall apply only to indoor or handheld UWB devices under 47 C.F.R. §§ 15.517 or 15.519 that operate in the 3.1-5.03 GHz and/or 5.65-10.6 GHz frequency bands. The fundamental emission of the UWB device shall not be located within the 5030-5650 MHz band. All other provisions of the UWB regulations shall continue to apply to these devices. The measurement of the average and peak emission levels for hopped, stepped, sequenced or gated systems shall be performed

  • transmitter is turned on and off for selected time intervals. The transmitter generally is turned off to listen for a response or to permit other transmitters to operate, such as through time division multiple access operations. UWB devices operating in the FSS C-band must comply with an emission limit of -41.3 dBm/MHz EIRP. See, e.g., 47 C.F.R. §§ 15.517 and 15.519. See Second MO&O, supra, at para. 94. On May 25, 2005, the Commission released a public notice inviting comments on the SIA Petition for Reconsideration.

  • Section 15.209. See e.g., 47 C.F.R. §§ 15.510(c)(4) and 15.515(d). Higher frequencies have more associated propagation losses. For example, there are approximately 58 dB of free space path loss at 3 meters for a 6 GHz signal versus 80 dB for an 80 GHz signal. See 47 C.F.R. §§ 15.250(d)(1), 15.252(b)(1) & (2), 15.509(d), 15.510(d)(3), 15.511(c), 15.513(d), 15.515(d), 15.517(c), and 15.519(c). Notice and Order, 25 FCC Rcd. 601, 604 (2010) at para. 8. The general emission limit is 500µV/m as measured at 3 meters from the tank enclosure, which is equivalent to an EIRP level of -41.3 dBm. Id., at 605, para. 11. Id., at 609, para. 22.
