Closed Loop Performance Analysis
Spirent's AirAccess EV is an integrated test platform for CDMA2000 1xEV-DO Access Terminals (ATs). Feature-rich, real-time network emulation enables both functional and protocol testing of ATs that exploit CDMA2000 1xEV's high-speed, high capacity wireless Internet capability. The closed loop system combines AirAccess EV, TAS4500 and SB-600 to provide high-speed data traffic analysis over an emulated CDMA network with RF impairments. The TAS4500 adds real-world radio channel emulation with programmable multi-path fading characteristics. The SMB-600 provides high-speed network performance analysis capabilities, including throughput, latency and frame loss metrics. The solution provides the necessary tools for carriers to characterize and select the optimal devices to deploy on their networks and at the same time enables wireless terminal manufacturers to maximize the data transfer performance of their AT devices.
