ly on these four inputs: The geographic plot of projected peak demand described in Chap. 31. The map identifying good and acceptable base station locations derived from the demand map and the principles of site location for managed interference. The site survey identifying low-cost base station sites such as existing towers or buildings with radio facilities. Projected maintenance as well as construction costs should be in- cluded in the site survey. The availability of low-cost transport. Considering all these elements, we can create a plan for the location of all the base stations serving a particular region. The plan should be validated to ensure that it meets the peak capacity with acceptable coverage and acceptable blocking rates in all areas. The plan also can be used to generate a detailed project plan and budget for de- ployment and a projected cost budget for operations, administration, and maintenance (OA&M). Now that we have decided where we will put each base station, we turn our atten- tion to the design of the equipment at each base station.

Source: CDMA CAPACITY AND QUALITY OPTIMIZATION Chapter Base Station Planning Now that we have decided where each base station is going to be, we need to decide what equipment goes into each base station. Our goals are to provide good or excellent coverage, reduce interference to other cells, maximize capacity, handle peak-traffic de- mand, reduce cost, and maintain reliability. We need to do this for new deployments, as well as for code division multiple access (CDMA) systems we create by migrating ex- listing systems from frequency division multiple access (FDMA) or time division multi- ple access (TDMA) to CDMA. In this chapter we will explore the tradeoffs among these goals and identify techniques we can use to achieve them. 33.1 Coverage T
