  • to Sprint Nextel.'' With respect to the latter, the TA Mediator notes that ``both [FRED] channels, if moved to the two proposed General Category Channels, will have greater separation [from Sprint's operations] after rebanding than they currently have.'' Finally, the TA Mediator notes that the proposed non-NPSPAC replacement channels ``are entitled to full interference protection against harmful interference by Section 90.673 of the FCC rules.'' The TA Mediator recommends, therefore, that the Commission find that the two proposed non-NPSPAC replacement channels will provide Genesee with comparable facilities. Decision. We agree with the TA Mediator that the replacement channels offered by Sprint for Genesee's FRED operations are comparable to its existing FRED channels. On these replacement channels, Genesee may operate its FRED

  • Reston, VA. On February 24, 2011, and March 3, 2011, in response to a complaint, agents from the Enforcement Bureau's San Diego Office using direction finding techniques and subsequent on/off testing found SMR station WPOH385 to be causing harmful interference to a public safety mobile radio system in Riverside County, California. The agents observed the following violation: 47 C.F.R. § 90.673(a): ``Strict Responsibility. Any licensee who, knowingly or unknowingly, directly or indirectly, causes or contributes to causing unacceptable interference to a non-cellular licensee in the 800 MHz band, as defined in this chapter, shall be strictly accountable to abate the interference, with full cooperation and utmost diligence, in the shortest time practicable.'' Nextel was notified of the harmful interference on February

  • also note that when the Commission updated its rules to reflect the reconfigured band plan in the 800 MHz band it inadvertently omitted the mutual aid channels from § 90.617(a). Therefore, we insert a reference to the mutual aid channels into § 90.617(a)(1) and note their new channel numbers based on the reconfigured band plan. 110 47 C.F.R. §§ 90.672, 90.673, 90.674. 111 See 800 MHz R&O, 19 FCC Rcd at 15030 ¶ 106. 112 See 47 C.F.R. § 90.673.

In implementing this decision the Commission adopted Section 90.672 (``Unacceptable interference to non-cellular 800 MHz licensees from ESMR or Part 22 Cellular Radiotelephone systems''), Section 90.673 (``Obligations to abate unacceptable interference''), Section 90.674 (``Interference resolution procedures before, during, and after band reconfiguration''), and Section 90.675 (``Information Exchange''). For example, a D Block transmission at 760 MHz, when combined with a C Block transmission at 750 MHz, will, in accordance with the 2F1-F2 formula for the calculation of 3rd order intermodulation, create an IM product at 770

  • occupied by incumbent licensees. EA-based 800 MHz SMR licensees also must abide by strict protections against unacceptable interference to non-cellular 800 MHz licensees under Section 90.672. As noted, EA-based 800 MHz SMR licensees must continue to meet the co-channel separation requirements in Section 90.621. Additionally, EA-based 800 MHz SMR licensees are strictly responsible for abating any unacceptable interference under Section 90.673, and must comply with the interference resolution procedures under Section 90.674. EWA suggests we clarify the applicability of the rule change adopted in this Report and Order in the Canada border area, because the existing protection from EA-based 800 MHz SMR licensees to adjacent site-based systems ``has always been calculated on a frequency-specific, co-channel contour basis.'' We reiterate that EA-based
