Spirent Vertex MIMO OTA solution


Spirent’s Vertex MIMO OTA solution models real-world over the air environments and can be used with both anechoic and reverberation chambers. For anechoic chambers, Vertex supports up to 32 RF probes and two carriers with 16 dual polarized probes or 8 dual polarized probes on one instrument. For reverberation chambers, up to four carriers can be aggregated on one instrument.

Repeatable and realistic
virtual drive testing

Capturing, saving and playing back an RF environment is easier than ever with Spirent’s Live2Lab Virtual Drive Test – Conversion Tool (VDT-CT). Drive a route once, capture RF scenarios with a third-party scanner, and play them back with Live2Lab for repeatable, realistic drive testing within minutes. For high-speed train or aircraft device performance scenarios, Spirent’s Live2Lab can import and analyze logged data at speeds up to 1,620 km/hr (1,007 mph).

Spirent Virtual Drive Testing

Features & benefits


The Vertex Wireless Channel Emulator is scalable to a broad range of applications. The hardware is capable of supporting as few as two bidirectional RF channels for basic RF testing and as many as 32 unidirectional RF channels to support high channel density applications in one instrument.


Separate RF modules are optimized for unidirectional or bi-directional applications and support a variety of different frequency bands; which allows Vertex to be configured for specific test needs using minimal hardware.

Wide frequency range and bandwidth

Vertex has an unmatched frequency range of 30MHz to 5925MHz with a single instrument. Individual bandwidths can be as high as 200MHz per channel and be combined up to 1GHz with concatenation to support frequency hopping.

High channel density in a compact space

Vertex supports up to 36 RF ports and 256 digital links in one 6U rack height. It enables more efficient use of hardware for tests that require higher RF channel counts, such as sophisticated MIMO applications and next-generation 5G services.

Remote programming interface (RPI)

Remote programing is supported through TCP/IP. The RPI commands provide seamless backward compatibly to Spirent’s VR5 HD channel emulator.

Comprehensive 2D/3D channel modeling

The built-in Vertex propagation library offers a vast selection of standard channel models and makes it easy to edit and save changes to create user-defined models, both classical and geometrical.
