We traf- fic engineered to meet the demand in Chap. 23, we located base stations to meet the demand in Chap. 32, we planned base station equipment to meet the demand in Chap. 33, and we spent the rest of Part 7 designing the rest of the system to meet the demand. In Chaps. 39 and 40 we discussed how to use system measurements and subscriber feedback to measure the demand and to calculate the mix of services SO that we could design our wireless telephone system better and more cheaply to meet the demand. The demand for our wireless telephone service is not a given fact of nature like the weather. We can exercise some control over subscriber demand for wireless service to reduce the cost of meeting that demand. We are already familiar with using different rates for different times of day as a way of encouraging off-peak usage. In this chapter we introduce the concept of choosing geographic locations for subscriber activity that reduce the cost of meeting that demand. We will discuss the kinds of places where we want the demand to be and how we can encourage our subscribers to be there when they use the system. The goal of this chapter is to show ways to increase net revenue most effectively by getting more new subscribers who will use their cellular telephones in areas that can support increased capacity inexpensively. Doing this requires a combination of engi- neering capacity analysis, economic analysis, and market analysis. There are a number of ideas that tie these disparate fields together: New subscribers increase revenue. However, with most voice call packages operating pri- marily on flat-fee usage, additional use of voice services by existing subscribers does not increase revenue. On the other hand, selling additional minu
