Keysight was able to achieve throughput speeds in the uplink (UL) of 3.5 gigabit per second (Gbps) using 5G new radio dual connectivity (NR-DC) with mmWave carrier aggregation (CA).
According to Keysight, the milestone was achieved by combining Keysight’s 5G Protocol R&D Toolset and a 2D multi-probe anechoic (MPAC) over-the-air (OTA) test chamber with a Snapdragon X65 5G Modem-RF System.
Potential use cases for such high throughput speeds include streaming live video content, gaming and data backup to a cloud environment and anything else that requires quick and reliable uploading of high volumes of data.
“The need for high uplink data throughput rates is on the rise, a trend driven by a multitude of 5G consumer applications, wireless broadband access for businesses and a growing number of private 5G deployments that support industrial internet of things use cases,” said Mosaab Abughalib, general manager of device development solutions at Keysight.
The 5G Protocol R&D Toolset is part of Keysight’s 5G network emulation solution portfolio. The toolset leverages the firm’s UXM 5G Wireless Test Platform, an integrated and compact signaling test platform with multiformat stack support, rich processing power and abundant RF resources, to emulate a 5G new radio (NR) network.
The demonstration of the high throughput took place in Qualcomm Technologies’ San Diego lab and used 5G NR-DC technology in 5G NR standalone (SA) mode.
The milestone was achieved using one component carrier (CC) in frequency range one (FR1) and four CCs in FR2 (also referred to mmWave spectrum), the company said.
“Together with Keysight, Qualcomm Technologies has realized several key industry milestones that will propel the wireless industry to the next phase of 5G NR deployments,” said Krishna Mandadapu, senior director, engineering at Qualcomm Technologies. “The 3.5Gbps in UL milestone is vital to many applications, such as uplink broadband connectivity for effective cloud storage of data and high-definition live streaming.”
