ACE MX2 MIMO Channel Emulator

Advanced MIMO platform with leading edge performance, power consumption, size and noise


2G/3G/4G LTE and beyond wireless access technologies promise speeds of 350 Mbps and higher for delivery of high-speed data, video and voice services.  High throughput delivery for LTE is achieved using orthogonal frequency-division multiplexing (OFDM) and advanced antenna techniques such as Multiple-Input, Multiple-Output (MIMO).  MIMO performance depends on the radio channels in which it operates, and accurate and repeatable lab characterization of RF environmental effects such as multipath and fading is critical for reliable testing of conformance, performance and interoperability of the systems.  Testing such conditions can only be achieved through the use of channel emulation.

At only 60% of the noise and in only 60% of the footprint of Azimuth’s earlier solutions, the ACE MX2 delivers on both the required performance and functionality while offering a solution that addresses the ever more demanding facilities requirements in the test labs at carriers, infrastructure and device OEMs as well as chipset vendors.

The ACE MX2 is a state-of-the-art channel emulator, purpose-built to address the latest challenges of ‘Real World’ testing and is designed to meet the demanding RF needs of MIMO systems.  The ACE MX2 product line combines industry-leading channel emulation capabilities in a comprehensive design to deliver a range of configurations for MIMO and/or SISO system testing, with uni- and bi-directional configurations.

The Azimuth ACE MX2 continues to deliver:

  • Rapid Setup and Automation
  • Unparalleled Ease-of-Use
  • Unmatched RF Performance and Fidelity
  • Superior Scalability and Flexibility
  • Outstanding Value
