- Bharti Airtel and Tata Group have announced a strategic partnership for implementing 5G network solutions for India, which will be available for commercial development from January 2022. Tata Group has developed an O-RAN (open-radio access network)-based radio and non-standalone architecture/stand-alone architecture (NSA/SA) core and has integrated a totally indigenous telecom stack, leveraging the capabilities of the group and its partners.
- The NSA/SA are radio technology that controls the signalling of 5G radio. While NSA can control signalling of 5G to the 4G core, the SA can connect the 5G radio directly to the 5G core network and control signalling does not depend on the 4G network.
- Airtel will pilot and deploy this indigenous solution as part of its 5G rollout plans in India and start the pilot in January 2022, as per the guidelines formulated by the government.
