Optus unveils first Australian demo of 5G NR-DC

Australian telco Optus has teamed with comms tech suppliers MediaTek and Ericsson to collectively full a country-first demonstration with the usage of new radio twin connectivity (NR-DC) expertise.

The mmWave spectrum band has gained significance this yr. 5G mmWave makes use of spectrum sources in frequencies above 24GHz to enhance sub-6GHz roll-outs and supply the complete potential of 5G, permitting operators so as to add huge capability to mobile networks with multi-gigabit wi-fi speeds and low-latency connectivity.

Earlier within the yr, the GSMA, the commerce physique for international cell operators, noticed that one of many key points for 5G in 2021 was the place and when millimetre wave (mmWave) programs might be cost-effective. Now many cell communications firms have introduced collective assist for 5G mmWave expertise globally.

In July 2021, Ericsson and MediaTek introduced what they claimed was a brand new pace benchmark for mmWave uplink. The companies mentioned they’d efficiently deployed provider aggregation expertise to realize a throughput of almost 500Mbps, double the present add speeds and the quickest recorded so far.

Utilizing the Taiwanese fabless semiconductor firm’s M80 take a look at platform and comms tech large Ericsson’s RAN Compute (basebands) and 5G radios, the demonstration is alleged to focus on the advantages of utilising each spectrum bands concurrently, with common and peak 5G speeds anticipated to extend considerably, in addition to the flexibility to increase protection over mmWave 5G networks over a larger distance.

Optus plans to roll out this new functionality throughout its 5G community later this yr as industrial mmWave gadgets start to hit the market.

The demonstration in Sydney showcased the usage of NR-DC expertise to combination its mid-band 3,500MHz spectrum property with its newly acquired mmWave 26GHz spectrum to spice up the 5G protection space whereas sustaining superfast 5G speeds.

“It is very important us that we have a look at revolutionary methods to amplify our 5G expertise property in order that our clients obtain the perfect and quickest 5G community doable,” mentioned Lambo Kanagaratnam, managing director networks at Optus. “The demonstration of NR twin connectivity aggregation is one other vital expertise milestone that may assist us meet this aim. We’re at all times on the lookout for methods to attach clients to expertise that improves their lives and the usage of 5G NR-DC will obtain precisely that, providing our 5G clients elevated protection and pace when related to the community.”

Martin Wiktorin, Ericsson’s head of world buyer unit Singtel, added: “The larger speeds and capability enabled by NR-DC expertise – when mixed with the ultra-low latency of 5G – will permit revolutionary service suppliers like Optus to satisfy rising community calls for from customers. This demonstration paves the way in which for the following technology of 5G use instances for customers, together with gaming and immersive media.”
