Channel Emulators

Advanced MIMO platforms for testing wireless networks, infrastructure, and devices

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 high bandwidths.

2G/3G/4G LTE Advanced and beyond 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.


ACE RNX – a paradigm shift in real world testing for multi-link technologies

The advent of LTE Advanced, with Carrier Aggregation, Small Cells, and HetNets, places new demands on current testing methodologies.  These requirements include establishing and testing multiple simultaneous radio links in the lab, emulating heterogeneous network scenarios, and scaling the complexity of test cases.  The calibration and coordination of the resulting testbeds further increases the demands placed upon test teams, both in test case design and testbed configuration.

ACE RNX offers:

  • Innovative software tools for multi-link test case design implementation and execution
    • Scenario Builder for Virtual Drive Testing
    • Link Builder for link centric testing
  • Unparalleled Ease-of-Use
  • Unmatched RF Performance and Fidelity
    • Improved Dynamic Range
    • Integrated Input Splitting and Output Combining
