Fujitsu and Qualcomm complete multi-gigabit call using 5G carrier aggregation

News

Fujitsu and Qualcomm have completed a 5G new radio (NR) data call with a multi-gigabit connection using 5G sub-6 GHz carrier aggregation.

The connection was established using non-standalone architecture, aggregating non-contiguous spectrum on 3.5 GHz and 4.9 GHz bands. The companies used a Fujitsu 5G NR base station and a 5G smartphone form factor test device powered by a Qualcomm Snapdragon X55 5G Modem-RF System.

They achieved more than 3 Gbps speeds in the demo. Qualcomm says its Snapdragon X55 5G Modem-RF System can support peak speeds up to 5 Gbps by aggregating 200 MHz across select 5G sub-6 GHz bands.

"This milestone with Fujitsu allows us to unlock 5G’s potential for seamless and pervasive connectivity," said Durga Malladi, senior vice president and general manager, 4G/5G, Qualcomm.

Carrier aggregation

Carrier aggregation combines multiple spectrum bands by aggregating component carriers (CC). The resulting increase in bandwidth boosts data throughput. Carrier aggregation is set to be an important feature of 5G to increase system capacity, improve reliability in weak signal conditions and deliver higher peak speeds.

“5G sub-6 GHz carrier aggregation provides operators with greater flexibility to boost 5G performance utilising their diverse spectrum assets,” a statement from Qualcomm said.

Masaki Taniguchi, senior vice president, mobile system business unit, Fujitsu, commented, "We are excited to elevate the use of 5G carrier aggregation to bring benefits for both operators and customers, and look forward to future work with Qualcomm Technologies to enhance what's possible for 5G networks."

Qualcomm says devices featuring carrier aggregation capabilities and powered by the Snapdragon X55 5G Modem-RF System are expected to be available later this year.
