Captive Non-Public Networks (CNPNs) are expected to play a valuable role in leveraging the secure,reliable, and ultra-low latency characteristics of 5G technology. The main findings of this policy brief are that the 5G CNPNs are designed to meet specific bespoke requirements of an enterprise and that 5G’s unique features enable CNPNs to support the implementation of innovative and highly specialised use cases/applications (such as remote healthcare, remote surgery, robotics, autonomous transport, selfdriving cars, independent drone-enabled delivery services, etc.). Private captive networks can be through a telco-led model or through the direct allocation of spectrum to enterprises. As both 5G public networks and private networks will play a critical role in building the next-generation mobile networks in India, this policy brief recommends a flexible and inclusive policy regime that promotes a fair and equitable ecosystem in implementing 5G CNPNs. The policy framework should include important issues like spectrum management policy for the availability of a dedicated and interference-free spectrum, flexibility in technical and financial options for enterprises for building their 5G CNPNs, support for innovation and capacity building for 5G, and fostering collaboration among enterprises, telcos, and telecom equipment and service providers, for strengthening the implementation of Industry 4.0 use cases in India.
