Finnish vendor Nokia and Australian mobile network operator (MNO) Optus have reported achieving what they called a ‘record-breaking aggregate site throughput of 10Gbps’ during a downlink speed demonstration using 800MHz of millimetre Wave (mmWave) spectrum at a live 5G site in Brisbane. According to the vendor, the decision to select this mixed commercial and industrial area of Brisbane for the demonstration was made keeping new use cases in mind as the pair sought to showcase the potential real-world benefits of mmWave to enterprise. The MNO, meanwhile, noted that the demo utilised what it called its ‘unique spectrum assets’, with the 10Gbps throughput achieved by aggregating its 5G spectrum bands of 3500MHz and 28GHz, on top of existing 4G spectrum band layers. Further, it claimed that in addition to an increase in total site throughput, the test demonstrated a significant increase in single user peak speed; Optus said that while it was seeing commercial single user peak speeds of around 1Gbps-2Gbps on existing 5G sites, it expects speeds closer to 4Gbps once the 5G mmWave layer is added.
Commenting on the matter, Lambo Kanagaratnam, Managing Director of Networks at Optus, said: ‘Today’s accomplishment is yet another 5G milestone for Optus as we push hard to deliver our customers with Australia’s fastest 5G network. We already know that 5G is fast but what we’re seeing here is innovative use of spectrum layers to deliver a single site with over 10Gbps throughput. This is a fantastic demonstration of how mmWave spectrum, integrated into existing 5G and 4G sites, has the capability to significantly boost overall site capacity – which will be a gamechanger for our customers.’
Optus currently has claims to have more than 1,200 5G sites in operation, covering ‘over 830,000 households in Australia’.
