MWC: Keysight demos tester for 1Gbit/s LTE-A

Keysight Technologies will demonstrate its E7515A UXM wireless test set at Mobile World Congress in Barcelona. The demonstration will feature LTE-A Pro end-to-end IP data throughput of 1Gbit/s using three component carriers, 4×4 and 2×2 downlink MIMO, and 256 QAM downlink modulation.

Also on display is the UXM’s first-to-market benchtop support for five component carrier (5CC) data throughput and 1.6Gbps data rates via 4CC carrier aggregation and 4×4 downlink MIMO.

Along with increased data throughput rates, the UXM supports 8×2 and 8×4 downlink MIMO, up to four component carriers in a single test set (in two bands).

Satish Dhanasekaran, general manager of Keysight’s Wireless Devices and Operator Segment writes:

With support for download speeds beyond 1Gbps, the UXM’s powerful platform continues to provide market-leading data throughput test capabilities. The latest UXM release also allows wireless device engineers to verify designs more efficiently with parallel test, VoLTE enhancements, and WLAN calling and offload.”

The UXM also supports UE-to-UE VoLTE calls in a single test set, as well as integrated IMS server capabilities such as IMS logging.

Also available is WLAN calling and offload, to ensure WLAN-capable devices are able to transition smoothly between LTE-A and WLAN. The addition of GSM/GPRS/EGPRS and TD-SCDMA/HSPA test applications allow one-box interRAT testing between LTE and 2G/3G, including PS handovers, CSFB, and SRVCC.

The UXM’s RF bench capabilities have also been expanded to reduce test time and cost of test with two-phone parallel RF test in a single UXM, one-box multi-format support including LTE/LTE-A, W-CDMA/HSPA+, TD-SCDMA/HSPA, and GSM/GPRS/EGPRS, as well as built-in CW interferers and the ability to change more connection parameters on the fly.
