Abstract
Test equipment operable to evaluate handoff in wireless networks can be configured as an infrastructure test system or a client mobility test system. The infrastructure test system includes a plurality of client emulating devices and a client motion emulator for testing real access points. Each client emulating device is operable to emulate multiple individual virtual mobile devices (“virtual mobile devices”). The client motion emulator computes a mathematical representation of the modeled network and motion of virtual mobile devices in that network. The client motion emulator employs the mathematical representation to calculate path loss between virtual mobile devices and the real access points in the modeled network. The calculated path loss information is transmitted to the virtual mobile devices. Path loss of communications from a virtual mobile device to an access point is implemented via a programmable attenuator.
