 circle is a good choice. This is then surrounded by a second, larger circle. Any location within the larger circle but outside the inner circle is an acceptable choice but not a good one. Planners can then seek cost-effective sites first within the good area and then within the acceptable area. However, if a particular site does not fall within its good Perhaps there are wind-driven or solar-battery systems that make a stand-alone wireless re- peater practical.

Planning Locations for Base Stations Planning for CDMA Capacity area in terms of radio properties, it may be necessary to adjust the locations of other cells or to use microcells, picocells, or repeaters to make up the difference. A vital part of site selection is finding cost-effective locations. A wireless service provider's ability to compete in the marketplace depends on its ability to offer its ser- vice for less. Base stations are a major cost component of a wireless telephone system, and it is in our interest not only to provide good radio performance but also to provide that service at low cost. The third part of site selection is being able to install sites quickly. Years of court- room zoning battles are a poor substitute for building base stations and realizing rev- enue from subscribers. We should identify sites where base station construction will be particularly easy and fast. Decent service soon can be a better business decision than great service that takes years longer to establish. When all the base station locations are considered, the final decision is usually a tradeoff between really good radio performance and cheap, fast base station installa- tion. The final judgment in this decision should involve the radio performance map de- scribed in Sec. 48.5 with its delineation of fourth-pilot delta values, four-cell zone
