The Telecom Regulatory Authority of India (Trai) is seeking industry feedback on a rating framework for digital connectivity in buildings or areas, with the aim of improving mobile coverage inside premises. Trai is asking stakeholders for their opinions on rating criteria, eligibility conditions, and the process of ascertaining ratings. Despite the expansion of 4G and 5G networks, digital connectivity inside buildings remains an issue that requires a new regulatory approach, according to Trai.
