Samsung Electronics claimed to have set a new 5G speed record during testing of E-UTRAN New Radio Dual Connectivity (EN-DC), a technology standardised in 3GPP Rel-15.
The company said it achieved a data rate of 5.23Gb/s during a trial at a laboratory in South Korea combining 40MHz of 4G spectrum with 800MHz of mmWave 5G and its Galaxy S20 Plus handset.
Ji-Yun Seol, Samsung VP and head of its networks unit’s Air Technology Group, stated the demonstration highlighted “the power of using a dual 4G and 5G approach, delivered directly to a single user”.
Unlike dynamic spectrum sharing, which allows a single block of spectrum to be shared between 4G and 5G, EN-DC involves the simultaneous receipt of signals from the technologies on user equipment, with the combination boosting network speeds, range and reliability.
Operators including SK Telecom [1], UScellular and Sprint (prior to its merger with T-Mobile US) previously outlined plans to deploy EN-DC.
Samsung’s announcement is the latest in something of a speed race around 5G.
In late 2020, Telstra, Ericsson and Qualcomm achieved a data rate of 5Gb/s [2] in trials using carrier aggregation, while in November 2020 Elisa and Nokia [3] hit 4Gb/s on two devices for a combined rate of 8Gb/s.
