C. 20554 News Media Information 202 / 418- 0500 Internet: http:// www. fcc. gov TTY: 1- 888- 835- 5322 DA 02- 1319 Released: June 6, 2002 WIRELESS TELECOMMUNICATIONS BUREAU ACCEPTS AND APPROVES CONSENSUS ANALYTICAL METHOD FOR DETERMINING ADDITIONAL FREQUENCY COORDINATION REQUIREMENTS FOR CERTAIN PRIVATE LAND MOBILE 150- 470 MHz APPLICATIONS By this Public Notice, the Wireless Telecommunications Bureau (Bureau) accepts and approves the consensus analytical method for determining whether Private Land Mobile Radio (PLMR) applications “trigger” the additional frequency coordination requirements of Sections 90.35( b)( 2)( iii) and 90.175( b) of the Commission’s Rules. 1 This consensus analytical method was recommended by the Commission’s certified frequency advisory committees (“ FACs” or “coordinators”) for PLMR spectrum. By way of background, applications for new or modified facilities on frequencies below 512 MHz shared by the former Power, Petroleum, Railroad, Manufacturers, Forest Products, Telephone Maintenance, Motor Carrier and/ or Automobile Emergency Radio Services prior to the Commission’s consolidation of such services into a single Industrial/ Business (I/ B) Pool may be coordinated by any FCC- certified I/ B Pool coordinator. 2 However, if the interference contour of a proposed station (19 dBu contour and 21 dBu contour for VHF and UHF, respectively) would overlap the service contour of an existing station licensed on one of these previously shared frequencies (37 dBu contour and 39 dBu contour for VHF and UHF, respectively), the written concurrence of the coordinator associated with the industry for which the existing station license was issued, or the written concurrence of the licensee of the existing station, must be obtained. 3 The coordinators’ engineering studies are not filed with the Commission unless specifically requested by the Commission’s staff. 1 47 C.

Sugrue, Esq., Chief, Wireless Telecommunications Bureau, FCC, dated June 26, 2001, at 2 (LMCC Letter). 3 See note 1, supra. See also LMCC Letter at 2. 1 - 2 - The Commission required that all FCC- certified coordinators reach a consensus on (1) a common analytical method for determining co- channel contour overlap using the values provided in Section 90.35( b)( 2)( iii) of the Commission’s Rules, and (2) adjacent channel service/ interference contour values. 4 On June 26, 2001, the Land Mobile Communications Council (LMCC), which includes all of the FACs as members, reported on the common analytical method for co- channel contour overlap agreed to by all the coordinators. 5 The LMCC also reported on the adjacent channel service/ interference contour values agreed to by all the coordinators. 6 Accordingly, we hereby approve and accept the consensus agreement as set forth in the Attachment hereto. For further information, contact Mr. Tom Eng of the Policy and Rules Branch, Public Safety and Private Wireless Division, Wireless Telecommunications Bureau at (202) 418- 0019, TTY (202) 418- 7233, teng@ fcc. gov. Action by the Chief, Public Safety and Private Wireless Division, Wireless Telecommunications Bureau. -FCC- 4 Replacement of Part 90 by Part 88 to Revise the Private Land Mobile Radio Services and Modify the Policies Governing Them and Examination of Exclusivity and Frequency Assignment Policies of the Private Land Mobile Services, PR Docket No. 92- 235, Fifth Memorandum Opinion and Order, 16 FCC Rcd 416 (2000) (Fifth MO& O). 5 LMCC Letter. The letter includes a list of specific frequencies. See id., Attachment A. 6 Id. at 2. 2 Attachment Page 1 of 2 The Frequency Advisory Committees’ (FACs) consensus on a common analytical method for determining contour overlap is to be used when coordinating frequencies that, prior to consolidation into the Industrial/ Business Pool, were shared by eligibles in following former, industry- specific radio services: € Power € Petroleum € Railroad € Manufacturers € Forest Products € Telephone Maintenance € Motor Carrier € Automobile Emergency For co- channel operations, the consensus values are 37 dBu and 39 dBu for the VHF and UHF service contours (50, 50), respectively; and 19 dBu and 21 dBu for the VHF and UHF interference contours (50,10), respectively. For adjacent channel operations, the consensus relies on a de- rating factor that is applicable when a 12.5 kHz narrowband applicant seeks to use channels offset from wideband incumbents using 25 kHz bandwidth equipment. It is also applicable when a 25 kHz wideband applicant seeks to use channels offset from narrowband incumbents using 12. 5 kHz equipment. Note: the consensus is not applicable when applicants are seeking adjacent channels offset by 7.5 kHz or 6.25 kHz. The FACs will treat such requests as co- channel operations subject to the contour values noted above. In the VHF band, for proposed systems offset in frequency by 15 kHz, the de- rating factor is 23.2 dB. The factor is added to the co- channel interference contour value of 19 dBu, producing a 42. 2 dBu (50,10) interference contour. This results in a 37/ 42. 2 dBu overlap criteria. In other words, if the proposed system’s 42.2 dBu (50,10) interference contour overlaps an incumbent’s 37 dBu (50,50) service contour, concurrence from the incumbent’s coordinator, or the incumbent itself, will be sought. In the UHF band, for proposed systems offset in frequency by 12.5 kHz, the de- rating factor is 12.5 dB. The factor is added to the co- channel interference contour value of 21 dBu, producing a 33. 5 dBu (50,10) interference contour. This results in a 39/ 33. 5 dBu overlap criteria. In other words, if the proposed system’s 33.5 dBu (50,10) interference contour overlaps an incumbent’s 39 dBu (50,50) service contour, concurrence from the incumbent’s coordinator, or the incumbent itself, will be sought. 3 Attachment Page 2 of 2 Fifth MO& O, PR Docket No. 92- 235, Shared Frequency List (MHz) 153.035 153.0425 153.050 153.0575 153.065 153.0725 153.080 153.0875 153.095 153.1025 153.110 153.1175 153.125 153.1325 153.140 153.1475 153.155 153.1625 153.170 153.1775 153.185 153.1925 153.200 153.2075 153.215 153.2225 153.230 153.2375 153.245 153.2525 153.260 153.2675 153.275 153.2825 153.290 153.2975 153.305 153.3125 153.320 153.3275 153.335 153.3425 153.350 153.3575 153.365 153.3725 153.380 153.3875 153.395 153.4025 153.425 153.4325 153.440 153.4475 153.455 153.4625 153.485 153.4925 153.500 153.5075 153.515 153.5225 153.545 153.5525 153.560 153.5675 153.575 153.5825 153.605 153.6125 153.620 153.6275 153.635 153.6425 153.665 153.6725 153.680 153.6875 158.145 158.1525 158.160 158.1675 158.175 158.1825 158.205 158.2125 158.220 158.2275 158.235 158.2425 158.265 158.2725 158.280 158.2875 158.295 158.3025 158.310 158.3175 158.325 158.3325 158.355 158.3625 158.370 158.3775 158.415 158.4225 158.430 158.4375 173.250 173.300 173.350 451.175 451.225 451.275 451.375 451.425 451.475 451.525 451.550 451.575 451.600 451.625 451.650 451.675 451.700 451.750 452.325 452.375 452.425 452.475 452.775 452.825 452.875 456.175 456.225 456.275 456.375 456.425 456.475 456.525 456.550 456.575 456.600 456.625 456.650 456.675 456.700 456.750 457.325 457.375 457.425 457.475 457.775 457.825 457.875 462.475 462.525 467.475 467.525 4
