Network can be extended without compromising 4G and NBIOT.
Optus, in partnership with Ericsson, has achieved coexistence of narrow band IoT (NBIoT) and Ericsson Spectrum Sharing between 5G and 4G on the 700MHz spectrum layer.
The use of the technology will assist in unlocking a quick and cost-effective way to enable 5G services on low frequency spectrum bands, giving a boost in 5G coverage, without compromising the excellent customer experience offered by mid-band 5G services.
Importantly, utilising Ericsson Spectrum Sharing (Ericsson’s unique dynamic spectrum sharing solution) on the 700MHz spectrum layer will maintain the 4G and NBIOT user experience while significantly extending the reach of 5G coverage for 5G users, both indoors and outdoors, helping to connect customers to 5G in the places that matter to them.
The implementation of this technology will enable Optus to further extend its 5G coverage footprint over a wider area, while leveraging the recent implementation of FDD+TDD 5G carrier aggregation on the mid-band spectrum to bring super-fast 5G speeds to 5G customers.
Pushing the limits of 5G even further Optus, together with Ericsson and Casa Systems, recently broke an Optus network milestone with a single user mmWave reaching peak speeds of over 5Gbps in a controlled environment at its Sydney headquarters, followed by 4.5Gbps in a live commercial environment in Sydney’s Kings Cross. This was all achieved using a Casa Systems AurusAI commercial CPE device on commercial Ericsson Radio Access Network.
Optus currently has more than 1300 5G sites across Sydney, Perth, Melbourne, Brisbane, Adelaide, Canberra as well as key areas outside of these cities.
