1 planning software system that AT&T uses to design and manage its PCS network. The Atoll computer <br />2 modeling software is used to create AT&T's radio frequency propagation maps. <br />3 Atoll's propagation maps predict the RF coverage and signal strengths that can be expected <br />4 over a geographic area based on certain data parameters. These parameters include: the radio <br />5 frequency used; the height, gain and orientation of the antennas; the terrain and obstacles through <br />6 which the RF signals are transmitted; and the strength of the RF signals. The propagation maps <br />7 predict the RF signal strength and quality of PCS service to be provided in the geographic areas shown <br />8 on the map. The Atoll propagation maps are highly reliable and scientifically based predictors of the <br />9 current and proposed quality of service in the greater Eugene area and throughout the United States. <br />10 The propagation maps included in the RF Justification and in the Addendum are shaded in two <br />11 different colors: green and yellow. If a geographic area is shaded green, it means that AT&T's existin <br />12 sites in its PCS network is projected to offer an acceptable quality of indoor coverage in that area. If a <br />13 geographic area is shaded ey //ow, it means that AT&T's proposed new site is projected to offer an <br />14 acceptable quality of indoor coverage in that area. If a geographic is not shaded at all, it means that <br />15 AT&T's existing andlor proposed sites are not projected to offer an acceptable quality of indoor <br />16 coverage in that area. AT&T's network design standard is to provide quality indoor coverage to its <br />17 subscribers. <br />18 The propagation maps included in the RF Justification and the Addendum for AT&T's existing <br />19 network are not shaded in the vicinity of the desired coverage area, and the maps clearly show that <br />20 there is a significant gap in AT&T's service. <br />21 Customer Complaints. AT&T also uses customer complaint data to evaluate the quality of its <br />22 existing network. AT&T has received numerous customer complaints about the quality of service near <br />23 the proposed site. AT&T's customers may notify AT&T of an area which has poor coverage through <br />24 several ways, including contacting AT&T's customer service representatives to report the location of <br />Declaration of Vicki Littlefield Page 5 <br />CU 14-3 <br />
