are creating, we need to decide where to put them. In Chap. 32, "Planning Locations for Base Stations," we look at issues of the air interface, as well as cost issues for cell sites, and discuss how to make the best possible choice for placing each base station, balancing these two issues.

Planning for CDMA Capacity Planning for CDMA Capacity also introduces tools such as cell splitting, microcells, picocells, and repeaters for cost-effective ways to provide good coverage, as well as tips for reducing the cost of base stations and backhaul transport. In Chap. 33, "Base Station Planning," we look into the details of planning each base station. We discuss coverage, downtilting antennas to reduce interference for nearby cells, sector plans, and carrier assignment. We also discuss how to handle peak traffic demand and how to migrate from frequency division multiple access (FDMA) or time division multiple access (TDMA) to CDMA and from cdmaOne to cdma2000. We end the chapter with discussions of quality, cost, and reliability issues in base station planning. In Chap. 34, "Mobile Switching Center (MSC) Planning," we turn our attention to planning the mobile switching center (MSC). MSC switches are expensive, so we show how to estimate MSC count to determine the minimum number of switches necessary to support a region while allowing some room for growth. We discuss location planning, equipment provisioning, assigning base stations to MSCs, and planning inter-MSC borders. We also help you plan the auxiliary components that are typically housed at the MSC site but are not part of the MSC switch. In Chap. 35, "Backhaul Planning," we turn our attention to transport. We discuss fan-out networks, backbone backhaul networks, transport for packet data that can bypass the MSC, reliability engineering
