Stronger mobile signals, fewer call drops, and faster internet speeds are set to become standard features in large residential and commercial buildings across Tamil Nadu. The state government has amended building regulations to make this possible. The government has revised the Tamil Nadu Combined Development and Building Rules, 2019, mandating dedicated in-building telecom infrastructure in large buildings and layouts to strengthen digital connectivity across the state. As per the government order, buildings with a floor area exceeding 750 square metres must provide dedicated telecom rooms under the newly introduced In-Building Solutions (IBS) framework. IBS refers to telecom infrastructure and associated equipment installed within a building to ensure high-speed data transmission, enhanced signal coverage, reduced call drops, and optimal spectrum usage. Projects exceeding 2,000 square metres must also submit a service plan with required specifications certified by a qualified telecom networking consultant. The infrastructure must be accessible to all authorised telecom service providers. The amendment is expected to directly benefit homebuyers by ensuring stronger indoor mobile signals, fewer call drops, and faster internet speeds, particularly in high-rise apartments and large residential complexes. By mandating access to all service providers, residents will have greater choice of networks. The move will also make buildings future-ready for expanding 5G services, enhance property value, and reduce the need for repeated road cutting and messy cabling in layouts.
