Telecom Italia flags 4Gbit/s 5G with Ericsson, Qualcomm
The Italian operator said the result was achieved using 26GHz millimeter wave (mmWave) frequencies, and builds on its previous milestone of 2Gbit/s speeds achieved in January 2020.
Qualcomm provided devices based on the Snapdragon X55 5G modem-RF system with QTM525 mmWave antenna module, and Ericsson supplied its radio system offerings.
TIM indicated it intends to focus on the provision of 5G fixed wireless access (FWA) services in areas not yet covered by high-speed fixed networks, and aims to deliver "dedicated" 5G indoor coverage that can be used for vertical applications.
Speeding up The operator said the achievement of the "first connection in Europe" that is "capable of permanently exceeding" a downlink speed of 4 Gbit/s represents a "new European record", although it provided few details on how it was able to get to such speeds.
Ericsson has already flagged the achievement of delivery speeds of up to 4.3 Gbit/s using carrier aggregation technology and test devices from Qualcomm.
In February, the Swedish vendor said this was achieved using eight component carriers (8CC) aggregating 800MHz of mmWave spectrum, and described 4.3 Gbit/s as the "fastest 5G speed to date."
Across the pond, Finland's Nokia said it achieved 5G speeds of up to 4.7 Gbit/s in tests performed on US carriers' commercial networks.
The vendor utilized 800MHz of mmWave spectrum — achieved by combining eight 100MHz channels in the 28GHz and 39GHz bands — and 40MHz of LTE spectrum using dual connectivity (EN-DC) functionality in Nokia's AirScale solution.
