  • systems, the requirement for coordination with Federal radio systems could be reduced. Harmful interference consists of interference to a radiocommunications service. See 47 C.F.R. § 15.3(m). Part 15 devices are not part of a ``service.'' Thus, interference caused to a Part 15 device by another Part 15 device does not constitute harmful interference. See 47 C.F.R. §§ 15.509(b), 15.511(b), and 15.513(b). The GPRIC consists of Geophysical Survey Systems, Inc., Mala Geoscience, Inc., and Sensors & Software, Inc. These parties manufacture GPRs and, according to the petition, account for over 95 percent of the GPRs sold in the U.S. The GPRIC requests for reconsideration will be addressed in a separate order dealing with several petitions for reconsideration and their associated comments.

  • Above 10600 15.209 limits -65.3 -53.3 -51.3 -41.3 -51.3 The high-frequency imaging system class includes GPRs, wall, and medical imaging devices. As with the low-frequency imaging systems, Government coordination is required for the operation of these devices, following the procedures described in Section 15.525 in Appendix D. Specific technical and operational requirements for high-frequency UWB devices are contained in Section 15.513 in Appendix D. Mid-frequency Imaging Systems. This class of imaging systems consists solely of through-wall and surveillance systems. These devices operate with a - 10 dB bandwidth between 1990 MHz and 10,600 MHz. Higher unwanted emission limits than those applied to the other classes of imaging devices are permitted. The emission limits are as follows: Frequency in MHz EIRP in

  • were included in the 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

  • with the gating active. 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

  • also more stringent than 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. Further, the Notice and Order specifically proposed to limit
