To ask the Secretary of State for Digital, Culture, Media and Sport, what proportion of (a) current and (b) planned 5G networks are (i) safety-related and (ii) safety-critical networks in Critical National Infrastructure and (iii) security-critical network functions.

It is not possible to quantify the proportion of current and planned 5G networks that are safety-related, safety-critical networks and security-critical network functions.
Safety-related and safety-critical networks in non-telecoms Critical National Infrastructure do not relate to public 5G networks.
Security-critical network functions in the 5G network relate to the sensitive ‘core’ of the mobile network. As no public networks have deployed a 5G core, it is not possible to calculate what proportion of the current 5G networks are covered by the ‘core’. Commercial decisions on the design and make-up of future 5G networks rests with the individual operators. It is therefore not possible to calculate what proportion of planned 5G networks are covered by the ‘core’.
