18.1 Performance Assessment
Computer simulation of mobile systems is a very powerful tool to assess the system performance. The “real-life” performance can, of course, be measured and evaluated in the field for an already deployed system and such values represent a valid example of performance for a certain system configuration. But there are several advantages with computer simulations:
• Evaluation can be made of system concepts that are not deployed or still under development.
• There is full control of the environment, including propagation parameters, traffic, system layout, etc., and full traceability of all parameters affecting the result.
• Well-controlled “experiments” comparing similar system concepts or parts of ...
