Tools and methods are provided to model and simulate the high-speed data channel and the traffic scheduling function, and tools and methods to simultaneously simulate the high-speed data channel and other voice and data services sharing the same radio carrier. The tools and methods estimate the quality of service and the capacity of the high-speed data channel, and also estimate the impact of the high-speed data channels on the quality of service and traffic capacity of other voice and data services on the same radio channel. The tools and method can be used in a wireless network planning tool to analyze a network that uses a radio carrier exclusively for high-speed data channels, such as cdma2000 EV-DO. The tools and method can also be used to analyze a network that combines high-speed data channels and CDMA based services on the same radio carrier, such as cdma2000 EV-DV or WCDMA HSDPA.
