Anritsu Enhances LTE Simulator with TD-LTE Carrier Aggregation

Anritsu Corporation, a global leader in wireless test and measurement, announced on September 10, 2013, an update to its LTE network simulator software to include support for the TD-LTE carrier aggregation feature. This enhancement allows Anritsu’s Signaling Tester Model MD8430A to simulate two carriers with a 2x2 MIMO configuration in the downlink, supporting bandwidths up to 40MHz.

The updated simulator now supports Category 6, enabling downlink throughput of up to 300Mbps. Support for both FDD and TD-LTE is available across all models. Anritsu offers a range of five LTE network simulator models.

Key Features of the MD8430A LTE Network Simulator

The MD8430A LTE network simulator offers a variety of features, including:

• Simulation of 2 active and 4 interfering LTE base stations on 4 RF channels.
• Simultaneous simulation of FDD and Time Division Duplex (TDD) base stations with SISO/2x2 MIMO/4x2 MIMO configurations.
• Multi-layer beamforming.
• Enhanced Multimedia Broadcast Multicast Service (eMBMS).
• Robust Header Compression (ROHC).
• Semi-Persistent Scheduling (SPS).

Additional Offerings from Anritsu

Anritsu also provides the following test systems:

• Model ME7873L-LTE RF Conformance Test System
• Model ME7834L-Mobile Device Test System, designed for protocol conformance (PC) and carrier acceptance test (CAT)

Carrier Aggregation Explained

Carrier aggregation is a technique used in LTE for both TDD/FDD systems.
