Qualcomm, Anritsu team on demo of 300 Mbps carrier aggregation

A new Gobi modem from Qualcomm (NASDAQ:QCOM) delivered peak downlink data rates of 300 Mbps in a demonstration that implemented LTE Advanced carrier aggregation over an Anritsu network simulator.

The device used in the demo was based upon Qualcomm Technologies' new Gobi 9x35 modem, an LTE-A Category 6 chipset that represents the company's fourth generation of multimode LTE modems. The chipset supports up to 40 MHz carrier aggregation on LTE FDD and TDD.

The 300 Mbps peak speed was achieved over Anritsu's MDS8430A LTE simulator using 20x20 MHz (20 MHz uplink and 20 MHz downlink) carrier aggregation. Anritsu contends its simulator is unique in that it offers advanced capabilities for testing carrier aggregation, such as the implementation of Hybrid Automatic Repeat Request (HARQ) under high-throughput conditions.

Top operators worldwide are implementing or planning to implement carrier aggregation to increase their usable bandwidth and, in turn, increase the bitrate, delivering higher data speeds to customers. In June 2013, SK Telecom rolled out the world's first LTE Advanced network with a commercial smartphone for use with the service.
