Anritsu Demonstrates LTE Advanced Carrier Aggregation Using MD8430A LTE Network Simulator and Signalion SORBAS UEs

Anritsu’s Full-Stack Demonstration Achieves 300 MB/S Downlink Data Rate with Aggregation of Two 20 MHz Carriers

Anritsu Company announces that its MD8430A LTE Network Simulator and Signalion’s SORBAS UE Simulator have successfully completed interoperability testing for LTE Advanced Carrier Aggregation. As a result of this testing, Anritsu will demonstrate the world’s first “full-stack” Carrier Aggregation capability in its booth (#3551) at CTIA Wireless 2012 in New Orleans, LA on May 8-10.

The demonstration of Carrier Aggregation is enabled with a single MD8430A, based on the network simulator’s unique availability of two active LTE base stations and four downlink RF transmitters in a single unit. When each active base station is configured with two RFs in a 2x2 MIMO configuration, 150 MB/s downlink throughput is available from each base station, and 300 MB/s downlink throughput is available after aggregation. Although the demonstration shows intra-band Carrier Aggregation in Band 1, both intra- and inter-band aggregation are available with the MD8430A, using either contiguous or non-contiguous carriers.

“We are pleased to show that we remain on the leading edge of LTE device testing,” said Wade Hulon, Vice President and General Manager of Anritsu Company. “We understand that Carrier Aggregation is a highly important feature for carriers that wish to provide ever-faster data rates to consumers. We look forward to leveraging the MD8430A’s capability as a building block throughout our product lines to provide conformance and carrier acceptance device test solutions to the industry.”

The MD8430A LTE Network Simulator can simulate up to two active and four interfering LTE base stations on up to four RF channels. A mix of Frequency Division Duplex (FDD) and Time Division Duplex (TDD) base stations can be simulated, with multiple MIMO configurations possible for each base station, including SISO, 2x2 MIMO or 4x2 MIMO. A full lineup of advanced Rel. 8 and Rel. 9 features are available, including Dual-Layer Beamforming, Enhanced Multimedia Broadcast Multicast Service (eMBMS), Robust Header Compression (RoHC), Semi Persistent Scheduling (SPS), and others. The MD8430A is used as a building block for Anritsu’s LTE conformance and carrier acceptance test solutions, including the ME7873L LTE RF Conformance Test System and ME7834L Mobile Device Test System.
