Australian mobile operator Optus and Finnish vendor Nokia have announced that they achieved a data session using 3 Components (3CC) Carrier Aggregation (CA) technology over a 5G Standalone (SA) network in Australia, claiming this to be ‘the first time this has been done using a commercial smartphone’. In a press release regarding the development it was noted that in the trial – which combined one FDD band carrier (2100MHz) with two TDD band carriers (2300MHz + 3500MHz) using CA technology – Nokia had used its latest commercial AirScale Baseband and radio portfolio powered by its Reefshark chipset over Optus’ commercial network.
Lambo Kanagaratnam, Vice President of Networks at Optus, said of the matter: ‘We’re always looking at ways that we can further optimise our network performance to benefit our customers. Once available commercially, this 3 NR Carrier operation will enable customers to achieve a higher 5G download speed at more places improving their overall 5G experience. Our Samsung Galaxy S22 customers will soon be the first to benefit from this technology enhancement with other handsets to follow shortly after.’
