Method for achieving optimum downlink capacity in the deployment of a wireless network

Radio systems are emerging that deliver packet data over-the-air with variable data rates and varying delay requirements. This paper presents a new link budget methodology applicable to the downlink of such systems. These radio systems have several key attributes, for example no downlink power control and best server selection that enable the new link budget methodology. The important design metrics are range and capacity, where we define capacity as the amount of data throughput the system can deliver. The new link budget methodology ensures optimum capacity is achieved by the use of a definition of what we term the interference margin.
