Channel Emulators

Advanced MIMO platforms with leading edge performance


Real world wireless IP products are subject to multipath effects that significantly alter performance of products as
perceived by the end user. Performance of Single-Input Single-Output (SISO) products degrade with multipath whereas Multiple-Input Multiple-Output (MIMO) product performance can improve in the presence of multipath. This is because MIMO products leverage multiple transmit and receive antennas to employ spatial multiplexing, adaptive antenna processing, and space time coding to deliver greater wireless throughput and range. The improved performance enables ubiquitous high-speed voice, video as well as data services.

Comprehensive performance characterization of MIMO products includes testing in controlled multipath environments that mimic real-world situations. To ensure repeatable results in a multipath environment, traditional field tests should be largely replaced by methodologies that use MIMO channel emulation which submit RF signals to real-word multipath conditions. An effective RF channel emulator can accurately create multipath behavior and measure its effect on system performance. 

MX2 – Azimuth’s newest MIMO channel emulator

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 MIMO.  MIMO performance depends on the radio channels in which is 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
