Many current cellular systems employ fixed channel assignment (FCA) schemes, where the cells are permanently assigned a subset of the available channels according to a frequency reuse plan. This chapter discusses the issues associated with radio coverage planning for cellular systems. Several schemes are suggested for improving the spectral efficiency in a cellular system including cell sectoring, cell splitting, reuse partitioning, switched beam smart antenna systems, selective base station (BS) diversity, and overlay/underlay schemes. Although the concepts are developed for systems that employ FCA, they will in many cases apply to those that use dynamic channel assignment (DCA).
