MIMO channel emulator for Wi-Fi test
Staff -- Test & Measurement World, 12/1/2005
The Azimuth Channel Emulator (ACE) 400NB reproduces 4x4 multipath environments with channel correlation to test multiple-input-multiple-output (MIMO) or single-input-single-output (SISO) wireless-LAN implementations. It is a stand-alone testing platform that can be used with current 802.11a/b/g devices and future 802.11n devices.
The ACE 400NB emulates real-world conditions in a repeatable, controlled manner for efficient real-time performance testing of chipsets, clients, and access points. It includes bidirectional 4x4 multipath channel emulation with correlated channels; built-in support for six real-time channel models for typical Wi-Fi scenarios; direct connections to 802.11 devices (no external RF devices required) to simplify setup; a GUI-based configuration to select the channel model; TCL script control with one mouse click; and Azimuth's patented SmartMotion attenuation system for precise measurement of performance over range.
Base price: $159,220. Azimuth Systems, www.azimuthsystems.com.
