Its property-rating framework evaluates more than mobile signal: it also considers fiber readiness, Wi-Fi, broadband performance, redundancy and preparation for future needs. The rating is currently voluntary, according to TRAI; the agency’s recommendations to government are not a nationwide construction mandate.
Why connectivity needs to be considered during building design
Mobile signals can weaken indoors because steel and concrete in building walls and other structures attenuate radio signals. TRAI says higher-frequency bands used for high-speed 4G and 5G are more affected by these materials than 2G bands. Planning connectivity infrastructure during construction can make it easier to provide coverage through the building rather than relying only on signals entering from outside. TRAI’s April 22, 2025 press release says studies indicated that 70–80% of mobile data consumption takes place inside buildings or indoor areas; the release does not identify the underlying study in the cited passage.
TRAI’s August 2025 announcement separately described the indoor share as “more than 80%.” These are different formulations in separate releases, not a single precisely stated measurement. TRAI’s April 2025 release gives the 70–80% range, while the August 2025 announcement uses “more than 80%.”
The practical implication for a construction project is to treat DCI as a building-system consideration, alongside services such as water, electricity and safety systems. Routes and space for fiber, equipment and in-building coverage can be considered before the building fabric and interior layouts are finalized.

What TRAI’s digital connectivity rating checks
TRAI notified the Rating of Properties for Digital Connectivity Regulations, 2024 on October 25, 2024, and issued its Manual for Rating of Properties for Digital Connectivity on August 13, 2025. The manual sets out a standard assessment method for Digital Connectivity Rating Agencies (DCRAs), and provides reference guidance for property managers and service providers planning, implementing and maintaining DCI. TRAI’s regulations and manual
The rating looks at several aspects of a property’s connectivity, rather than simply recording whether a phone receives a signal in one location.

- Infrastructure readiness: fiber availability and readiness, in-building solutions (IBS), distributed antenna systems (DAS), small cells and optical-fiber backbones.
- Coverage: mobile and Wi-Fi availability, including indoor coverage in areas such as basements, elevators and different floors.
- Performance and experience: broadband speeds and user experience.
- Resilience and future needs: redundancy and readiness to scale as connectivity requirements change.
The framework describes cellular, Wi-Fi, fiber and satellite broadband as possible connectivity options. Which infrastructure is appropriate depends on the property and its requirements; the rating is not a prescription that every building must install every type of system. TRAI’s FAQ
Who the framework is for
TRAI says the framework covers a range of property types, including residential and commercial buildings, malls, educational and healthcare facilities, airports, metro rail, stadiums and open spaces. It is relevant to developers and owners planning infrastructure, property managers responsible for implementation and upkeep, and service providers working on connectivity. A rating can also give tenants and prospective buyers a structured way to consider connectivity provisions when comparing properties.

According to TRAI’s FAQ, a property manager may apply through the rating platform and choose a DCRA. The FAQ also describes a review process: when documented feedback prompts a possible rating review, the property manager has a 90-day opportunity to address notified deficiencies before a rating change. TRAI’s FAQ
Is TRAI making connectivity planning mandatory?
No nationwide construction requirement is established by the sources cited here. TRAI’s FAQ says the property rating is currently voluntary. In 2023, TRAI made recommendations to government that included embedding DCI in building plans and the Model Building Bye-Laws context. Those recommendations are distinct from the later notified rating framework and do not, by themselves, establish a binding nationwide mandate. TRAI’s FAQ; TRAI’s 2023 recommendations

Building requirements can depend on state and municipal rules. The cited sources do not establish adoption status for every jurisdiction, so developers should check the building regulations that apply to their specific project rather than assume a uniform local requirement.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What a rating can—and cannot—tell you
A property rating assesses infrastructure and connectivity performance against TRAI’s framework. It does not guarantee uninterrupted service from every mobile operator: actual availability and performance also depend on operator networks and other conditions. For project planning or property comparisons, useful points to examine include fiber readiness, coverage on each floor and in basements and elevators, Wi-Fi, broadband performance, suitable in-building systems, redundancy and capacity for future requirements.
