U S WEST Wireless,LLC. • <br /> 426 North Fairview Avenue Room 101 <br /> St.Paul,MN 55014 <br /> tgI:WEST <br /> respectively, while at the same time providing coverage to the surrounding <br /> community in the heart of Elk River, a cell site was deemed necessary to be situated <br /> in the vicinity of this location. To accomplish these coverage objectives our monopole <br /> has been designed to be situated at a height of 150 ft. at the proposed location. <br /> Capacity: CDMA technology has an inherent capacity advantage over <br /> comparable (current) analog technologies. A conservative calculation puts this <br /> capacity advantage at six times for comparable operating bandwidths. For a 1.23 <br /> MHz bandwidth (the bandwidth to be utilized in US WEST's initial deployment), <br /> about 1000 subscribers per site can be supported during busy hour (with an <br /> acceptable call blocking probability). For the corridor along Hwy. 10 which SCLOO5A <br /> is designed to cover, the Minnesota DOT gives the traffic volume as approximately <br /> 31,000 automobiles per day, on average. A reasonable estimate of initial customer <br /> penetration puts the traffic carrying requirements for a particular US WEST site in this <br /> vicinity at approximately 250 mobiles during busy hour which equates to at least one <br /> PCS cell site. <br /> Interference: Our equipment manufacturer constructed our equipment to <br /> comply with FCC mandated regulations, and we will not cause any interference to <br /> any other broadcast systems. <br /> Site Selection:The site at 19050 Industrial Blvd. NW. was selected because: (1) <br /> drive test results indicated that this site fulfilled all our coverage requirements; (2) i <br /> mathematical analysis showed that it could meet the imposed capacity constraints. <br /> Please do not hesitate to contact me directly at (612)642-6039 should you have <br /> any questions regarding the study. <br /> Sincerely, / <br /> /0 t—Z.4/C <br /> Khursheed Khan <br /> RF Design Engineer <br /> • <br /> Access2T'Advanced PCST" <br /> Paging Services <br />
