5G, multi-layer architecture and RICs are the key areas of focus for players in the NAO space

5G network automation is driving network automation and orchestration revenue growth

The worldwide network automation and orchestration (NAO) market grew by 5.1% between 2019 and 2020 to USD8.8 billion due to the continued adoption of automation solutions, the virtualisation of the 4G core and the deployment of the cloud-native 5G core. Communications service provider (CSP) spending on network control and orchestration (NCO) technology also grew during this timeframe (by 16.5%). Huawei accounted for 19% of the total NAO revenue in 2020.
