- At Mobile World Congress 2021, Keysight Technologies demonstrated ten gigabits per second (Gbps) data transmission over a 5G new radio dual connectivity (NR-DC) connection.
- This demonstration was done in close collaboration with Qualcomm Technologies.
The demonstration implemented Keysight’s network emulation platform and Snapdragon X65 5G RF modem with Qualcomm’s QTM545 mmWave antenna module to aggregate 5G spectrum in the millimeter wave (mmWave) domain and in the sub-6GHz frequency bands.
To establish a 5G NR data connection based on the 3GPP Rel-16 standard, Qualcomm Technologies also used Keysight’s 5G Protocol R&D Toolset solution, part of the U.S. company’s suite of network emulation solutions.
The achievement is part of a long-term collaboration between the two companies to support the commercialization of 5G communication devices.
NR-DC (new radio dual connectivity) technology enables 5G NR (New Radio) communication devices to simultaneously connect and aggregate multiple NR cells. This significantly increases data transmission speeds.
Cao Peng, vice president and general manager of the wireless test business at Keysight, said, “This achievement clearly shows that the industry has entered the second phase of 5G NR deployment, which will enable the implementation of wireless communications according to the latest 3GPP Release 16 specification.”
The demonstration implemented frequencies in the FR1 and FR2 (mmWave) bands. This allows 5G user equipment (UE) to exploit wide bandwidths and higher order modulation, leading to data transfer speeds exceeding 10 Gbps. The flexible use of spectrum, combined with higher speed data transmissions, enables mobile operators to deploy dynamic 5G services in high density wireless network areas where bandwidth resources must be managed efficiently to support the most advanced applications.
