The rapid development of wireless technologies has made it possible to use VoIP and other delay/jitter sensitive applications. If multiple access technologies are available, there are several parameters to consider when choosing which one to use. This thesis investigates how VoIP and video applications scale while roaming seamlessly between different technologies. The networks are evaluated based on capacity and load to base a decision for handover. Metrics based on deviation and delay is a good way to measure this. Some changes to the formula are proposed, including a function ...
