Abstract
A hybrid test bed mixes simulated and actual wireless communication network entities in a real-time packet data simulation. In at least one embodiment, the test bed supports end-to-end simulation for a packet data application running on a mobile station simulator. The test bed provides a realistic assessment of that application'"'"'s real-time performance by constraining packet data transmissions from a radio base station simulator to the mobile station simulator according to peak data throughput estimates and mobility event processing determined from a detailed wireless communication network simulation. Additionally, the test bed includes or is associated with a graphical display system providing real-time performance information.
