This chapter describes radio frequency (RF) system engineering, design principles, and field results for a code division multiple access (CDMA) cellular distributed antenna system (DAS). The CDMA DAS has many advantages compared to the traditional macrocellular system. The advantages include higher capacity, better performance, and a faster and potentially more cost-effective deployment. We present descriptions of DAS characteristics in terms of transport mechanisms from the base station to the distributed antennas, and the system specifications of a DAS. We present the theoretical analysis on propagation modeling, link budget, and capacity budget. We address how to tune the propagation models using drive test results. We also validate our theoretical performance analysis using real field performance measurement results. Also discussed is the design guideline of how to deploy a CDMA DAS based on real-life experiences.
