The deployment of 5G networks, which could be as much as 10 times more efficient than 4G networks, has the potential to improve the safety of self-driving cars, according to Gartner.  

With this new level of network capability, communications service providers can secure future market opportunities with manufacturers of autonomous vehicles in the fields of driver safety and data processing and management, it says.  

Globally, major 5G deployments are expected from 2020. Ericsson forecasts over 1 billion 5G subscriptions for enhanced mobile broadband by the end of 2023, accounting for around 12% of all mobile subscriptions, it says.
