There are a growing number of legacy two-way wireless system types. Many of the systems are multi-site, and many of those include automatic handover services as the users move from site to site within the same system type. Most of these sys- tem infrastructures are single mode while many of the newer communication units are multi-mode to provide functionality as the user moves among var- ying system types. Users require geographic handover, no matter if it is site-to-site or system-to- system. System-to-system handover is provided when the systems are of the same type. System-to-system handover is not provided when the systems are not the same type.
