Emulators Meet Evolving LTE-Advanced Test Needs

Azimuth Systems has added new capabilities to its ACE MX and MX2 channel emulators that directly address LTE-Advanced test requirements, such as carrier aggregation and coordination across multiple wireless links. Offering a range of configurations for MIMO system testing, the ACE channel-emulator line creates complex fading channels for testing advanced wireless technology and devices.

New features of the MX and MX2 bidirectional channel emulators include:

• Multilink channel-emulator topologies supporting configurations of up to 16 RF links and 64 digital fading channels;
• Reciprocal path loss, which provides intelligent mapping of dynamic downlink models to the uplink channel;
• Automation for test-bed control, including user equipment, network emulators, and diagnostic monitors, all run by a test executive on a single PC.

These new capabilities support the multi-RAT and carrier-aggregation test beds of operators, OEMs, and chipset vendors. Additionally, ACE channel emulators can be integrated into Azimuth’s modular, fully automated, end-to-end platform for mobile performance testing.
