These strategies must be supported by realistic business plans both in terms of future service demand estimates and the requirement for investment in network infrastructure. Evaluating the requirement for network infrastructure can be achieved using system dimensioning tools capable of assessing both the radio access and the core network components. Having found an attractive business opportunity, system deployment must be preceded by careful network planning. The network planning tool must be capable of accurately modeling the system behaviour when loaded with the expected traffic profile. The third generation cellular systems will offer services well beyond the capabilities of t
