A CDMA based radio system capable of supporting UMTS services up to 2 Mbit/s user bit rates is considered. The performance of the system is evaluated by link level simulations, cell range calculations and network level capacity simulations in the urban macro cell, urban street micro cell and indoor cell environment using three bandwidths. According to the results 2 Mbit/s transmission was achieved with reasonable signal-to-noise ratio in all the simulated environments. Moreover, sufficient cell ranges can be realized using reasonable power levels in the indoor and micro cell environments. In the macro cell environment the achievable range should be larger. In the considered case the downlink capacity of the cellular network offering 2 Mbit/s services is only moderate and much lower than the uplink capacity
