The intent of the deployed system will be to provide <br />ubiquitous wireless services to the Twin Cities communities. In order to meet the <br />requirements of continuous (seamless) coverage and to be able to cany the projected <br />traffic and to COver the surrounding neighborhoods~ two cell sites (MINI02, MINI04) <br />are currently designed to be built at 2233 Hamline Avenue N and 2582 Long Lake <br />Road, ~oseville. <br /> <br />While choosing an appropriate location for a proposed cell site. we try to meet <br />the coverage and capacity objectives of that particular service area. In a typical <br />situation when a system designer is faced with a 1rade off between capacity and <br />coverage, the RF design engineer applies the knowledge of the terrain and surrounding <br />clutter to the site selection process. In choosing a site at 2233 RamIine Avenue N, <br />Roseville, the analysis ttom theoretical modeling and actual drive tests showed that in <br />order to cover the very heavily traveled intersections ofRte. 36 with RamUne and <br />Snelling Avenues and to cover the neighborhoods in the immediate vicinity it is <br />imperati"VC to locate a site near the Rte. 36 and Hamline Avenue junction. Since <br />coverage along with capacity is a major concern while desianing a CDMA technology <br />based PCS system, both these criteria had to be taken into consideration while locating <br />MlNl02. The accompanying coverage map will conclusively show the need for a cell <br />site at our proposed location. Regarding capacity, CDMA technology has an iDherent <br />advantage over comparable (current) analog technologies. A conservative calculation <br />puts this capacity advantage at six times for comparable operating bandwidths. For a <br />1.25 :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 acceptable <br />call blocking probability). For the intersection around Snelling Avenue and Rte. 36 the <br />
