Macro-mobility management in EVDO

This article describes the design and best practices for macromobility management in EV-DO, including mobility across EV-DO subnets and mobility across network that support different air interface technology (i.e., between 1x and EV-DO, or between different revisions of EVDO). In particular, the following three topics related to the EV-DO systems are discussed in detail: Conditions under which an EV-DO subnet should be created and how to create such subnets; Mobility across areas covered by sectors with different physical layer capabilities without creating EV-DO subnets; Data session mobility between networks supporting EV-DO and 1x.
