Anritsu Corp. and Signalion GmbH conducted a successful IOT for the 3GPP LTE-Advanced ‘carrier aggregation’ feature with an IP downlink throughput of 300 Mbps. Both companies are leaders in providing test solutions for the 3GPP LTE radio technology and as a result of this IOT collaboration, the two companies will supply dependable test solutions for 3GPP LTE-Advanced.

This IOT has been conducted using the MD8430A LTE base station simulator for LTE terminal verification developed by Anritsu and the SORBAS LTE terminal simulator for LTE base station verification developed by Signalion. Both solutions have been enhanced with carrier aggregation functionality of the LTE-Advanced standard as a trial development independently by each company.

During the IOT an average downlink throughput of 300 Mbps was achieved in an end-to-end connection at the IP layer. In the trial two band-1 component carriers with 20 MHz bandwidth each were aggregated resulting in a total bandwidth of 40 MHz.

The next step is to reach an average uplink throughput of 100 Mbps at the IP layer, as well as to include additional functionality for LTE-Advanced as required by the LTE-A market. Both companies will verify their test equipment peer-to-peer. This IOT by two independent companies provides for a higher dependability of LTE-A test equipment at a very early stage of LTE-A product development.

“We are excited about the success of our IOT collaboration with Anritsu,” said Tim Hentschel, Managing Director of Signalion. “Anritsu and Signalion have shown an impressive growth in the LTE test market. This latest success proves Anritsu’s and Signalion’s very active support of the LTE-Advanced eco system. By providing our customers with such advanced testing capabilities, we are contributing to an early realization of the LTE-Advanced technology in Japan, in Europe and worldwide.”

Toshihiko Takahashi, CEO/R&D Director of Anritsu, added, ” Having succeeded in the IOT of LTE-Advanced for the first time in the world proves the high level of the technical capabilities of Anritsu and Signalion. R&D of LTE-Advanced is at a fast pace and it is accelerating as we speak, in order to respond to the rapid increase of mobile data traffic. Based on this result Anritsu accelerates the development of test and measurement solutions and powerfully supports an early realization of LTE-Advanced.”
