As per studies, 70–80% of mobile data consumption occurs indoors. With 4G and 5G relying on high-frequency bands, these signals are more easily obstructed by building materials such as steel and concrete, especially when compared to 2G bands. In light of this, and with the ever-growing demand for faster and more reliable digital services driven by widespread digitisation, strong in-building digital connectivity has become a critical necessity.

Recognising this need, the Telecom Regulatory Authority of India (TRAI) organised a workshop for senior officers from States and Union Territories to discuss its “Regulation on Rating of Properties for Digital Connectivity, 2024”. The session was chaired by Shri Anil Kumar Lahoti, Chairman, TRAI, and was attended by over 125 participants, including senior officials from Housing, Urban Development, and IT departments.

In his opening remarks, the Chairman highlighted the pivotal role States and UTs play in aligning developers and telecom service providers to incorporate Digital Connectivity Infrastructure (DCI) into buildings, much like other essential services. The new TRAI regulations propose a star-rating system to assess the quality of digital connectivity within buildings—akin to ratings for green buildings or energy-efficient appliances.

These ratings will be dynamic, reviewed throughout the lifecycle of a property. TRAI has already initiated the empanelment of Digital Connectivity Rating Agencies (DCRAs). The workshop also detailed how the National Building Code (NBC) and Model Building By-Laws (MBBL) can be adapted to include provisions for DCI.

Through a comprehensive presentation and Q&A session, participants gained insight into the assessment methodology, regulation framework, and how ratings can inform consumers while encouraging developers to enhance in-building connectivity. Importantly, the regulation allows consumers and property managers to seek re-evaluation if there is a change—whether degradation or improvement—in connectivity.

Dr. M. P. Tangirala, Member, TRAI, concluded the workshop with closing remarks, underscoring the value of collaboration in achieving seamless digital infrastructure across the country’s built environment.
