Attachment C ‐ Compliance with FCC §25.136 Hawaii Pacific Teleport (HPT) is seeking authorization for operation in the 27.5‐28.35 GHz band under the FCC Rules, section §25.136 (a)(4). HPT will operate the Kapolei Ka‐band terminal at a site which is collocated with an existing licensed facility in this band, where the population density limits will be met, and there are no existing operational UMFUS facilities. Currently in the County of Oahu there are two earth stations licensed for the operation in 27.5‐ 28.35 GHz band: the O3b Earth Station in Haleiwa, HI with call sign E100088 and the ViaSat Kapolei Earth Station Call sign E110046. The HPT Kapolei Earth Station is collocated with the ViaSat earth station site and therefore would comply with FCC rules, section §25.136(a)(4)(i). The emissions from the HPT Kapolei terminal will be equal to or greater than the limit of ‐77.6 dBm/m²/MHz in calculated area with a maximum excursion of 1155 meters at an azimuth of 238 degrees. For azimuth angles 0 to 360 around the earth station the maximum distance required where the PFD limit is met is shown in Table 1 below. This data was determine using the link budget information included in Table and the antenna gain pattern shown in Figure 1 below. As can be seen from the Figure 2 below in the PFD limit area calculated around the earth station the population is well below 0.1 percent for Oahu County. HPT complies with FCC rules, section §25.136(a)(4)(ii). As can also be seen from Figure 2 there are no major event venues, arterial streets, interstates, US Highways, urban mass transit routes, passenger railroads or cruise ship ports within the area shown, HPT complies with FCC rules, section §25.136(a)(4)(iii). With respect to FCC Rules, Section §25.136(a)(4)(iv) HPT is not aware of any UMFUS licensees operating existing constructed and in operation facilities within the area in which the earth station generates a power flux density (PFD), at 10 meters above ground level, of greater than or equal to −77.6 dBm/m²/MHz, {01069527‐1 }
