Nokia has announced the expansion of its AirScale portfolio with a number of new product innovations designed to fulfil the evolving needs of 5G networks. This includes the launch of a Dynamic Spectrum Sharing (DSS) software upgrade for existing Nokia AirScale base stations, and the Nokia AirScale All-in-Cloud base station, aimed at boosting network efficiency.
As part of the portfolio expansion, Nokia has launched a range of new AirScale products, including compact dual and triple-band remote radio heads to support cell site deployment requirements. It has also introduced several new high-performance massive MIMO adaptive antennas to deliver 5G coverage and high capacity. These new upgrades support 4G and 5G networks today, increase cell capacity, and lower the total cost of ownership (TCO) bringing 5G experiences to businesses and consumers faster.
“All of these upgrades are designed to support mobile operators in their efforts to deliver compelling 5G experiences to their customers faster and at a lower cost,” said Tommi Uitto, President of Mobile Networks at Nokia. “They will also support with increased demand for capacity, which is critical in the current environment. Our latest portfolio innovations will help operators to take advantage of the 5G world by delivering new use cases and business models and add new revenue streams.”
Nokia’s DSS solution
Nokia’s DSS solution, delivered as a software upgrade to existing Nokia AirScale base stations supports 2G, 3G and 4G technologies, enabling a smooth evolution towards 5G deployments. The 4G–5G DSS feature automatically coordinates the spectrum usage between 4G and 5G, helping them reuse existing 4G radio networks and speed up 5G rollouts.
Typically, 5G is launched in higher mmWave or cmWave spectrum, while existing 4G is deployed in the lower spectrum range. By reusing the lower-frequency 4G spectrum, 5G coverage can be achieved faster and at a lower cost.
Nokia has also announced a number of 5G cloud radio access network (RAN) innovations, including the Nokia AirScale All-in-Cloud base station. This virtualizes real-time baseband and puts the baseband processing power at the edge of the network to meet extremely low-latency requirements, boosting the efficiency of the network, and helping in the delivery of edge-based 5G use cases.
Initial deliveries of Nokia’s DSS solution are planned to start in April 2020, with volume shipments expected by July, in line with the availability of DSS-capable mobile devices.
