Nokia, Samsung and Australian mobile operator Optus have made the first data call using 3-component carrier aggregation (3CC) technology on a standalone 5G network (5G SA) at the using a commercial smartphone.
This achievement paves the way for more advanced commercial 5G networks and revolutionary new use cases such as augmented and virtual reality (AR and VR) applications that rely on high-performance connectivity.
“We are always looking for ways to further optimize the performance of our network for the benefit of our customers,” said Lambo Kanagaratnam, vice president of networks at Optus.
5G SA speed record
“Once commercially available, this 3 NR Carrier operation will enable customers to achieve higher 5G download speeds at more locations, improving their overall 5G experience. Our Samsung Galaxy S22 customers will soon be the first to benefit from this technological improvement with other handsets to follow soon after.
Most 5G deployments to date have relied on 5G non-standalone 5G (5G NSA), which uses new radio technologies but still relies on the underlying 4G core.
SA 5G uses a new cloud-based virtual core that allows data to be processed closer to the point of collection and enables features such as network slicing. This enables guaranteed speeds, increased reliability, and ultra-low latency.
Meanwhile, carrier aggregation merges separate spectrum bands to exploit the advantages of each to deliver advancements in speed, capacity and coverage, while allowing operators to maximize the efficiency of their assets.
For this particular trial, the partners used a combination of 2.1 GHz, 2.3 GHz and 3.5 GHz frequencies combined with commercially available 5G equipment from Nokia and a Samsung Galaxy S22 Ultra smartphone.
“Nokia is delighted to bring our market-leading 5G technology to Australia to deliver another 5G world first with Optus,” added Robert Joyce, Chief Technology Officer, Nokia Oceania. “This enhancement to the market-leading 5G network provided by Nokia will enable Optus to continue to deliver superior network performance to its customers.”
In tests earlier in 2022, Nokia achieved speeds of 3Gbps using 3CC AC in trials with China Mobile and MediaTek.
