Keysight collaborates with Qualcomm on uplink data rate speeds

A major player in T&M technology, Keysight Technologies Inc. has collaborated with Qualcomm Technologies Inc., to demonstrate uplink (UL) data rate speeds of 3.5 gigabits per second (Gbps) using new radio connectivity dual 5G (NR-DC) with mmWave carrier aggregation (AC).

This milestone was accomplished by combining Keysight’s 5G protocol R&D toolset and 2D live (OTA) multi-probe anechoic test chamber (MPAC) with a Snapdragon X65 5G modem-RF system. Use cases such as streaming live video content, gaming, and backing up data in a cloud environment depend on wireless connections that support fast and reliable downloading of large volumes of data.

“The need for high uplink data rates is on the rise, a trend driven by a slew of consumer 5G applications, wireless broadband access for businesses, and a growing number of private 5G deployments that support industrial use cases of the Internet of Things,” says Mosaab. Abughalib, General Manager of Device Development Solutions at Keysight.

The 5G protocol R&D toolset, part of Keysight’s 5G network emulation solutions portfolio, is based on the company’s UXM 5G wireless test platform, a Integrated and compact signaling test form with multi-format stack support, rich processing power and abundant RF resources, to emulate a new 5G (NR) radio network. The demonstration, which took place in Qualcomm Technologies’ San Diego lab, used 5G NR-DC technology in 5G NR standalone (SA) mode. The milestone was achieved by using one component carrier (CC) in frequency range one (FR1) and four CCs in FR2 (also known as mmWave spectrum).

“Together with Keysight, Qualcomm Technologies has achieved several key industry milestones that will propel the wireless industry into the next phase of 5G NR deployments,” adds Krishna Mandadapu, senior director of engineering at Qualcomm Technologies. “The 3.5 Gbps milestone in UL is vital for many applications, such as high-speed uplink connectivity for efficient cloud data storage and high-definition live streaming.”

Qualcomm Technologies uses Keysight’s 5G network emulation solutions to verify 5G NR 3GPP Rel-16, RF and Radio Resource Management (RRM) protocol test requirements using SA mode. This allows the modem vendor to capitalize on early commercial introductions of advanced 5G NR functionality, accelerating the adoption of smart factory, industrial automation, smart city and autonomous vehicle applications.
