Regulating the transmission rate of non-real-time applications offers enhanced flexibility for QoS management and capacity control on a CDMA link. For a system working at saturation conditions, controlling data rates can further enhance its capacity. A more thorough investigation of this possibility and the trade-offs involved is presented in this paper. We analytically study the Erlang capacity of CDMA when scaling the physical transmission rates on the link. We consider single and multiple service classes, extending our analysis to an asymptotic regime. It is shown that the most efficient way of boosting this capacity is by lowering transmission rates, which nevertheless comes at the expense of increased transfer delays and energy consumption.
