Broadcasting – D2M Technology Moves Ahead After Successful Final Compatibility Tests
Broadcasting – Direct-to-Mobile (D2M) broadcasting technology has taken a significant step toward implementation after successfully completing a new round of laboratory and field evaluations. The latest findings indicate that the technology can function alongside existing mobile communication networks without affecting regular voice calls or SMS services, addressing a key concern that had delayed broader deployment.
Final Testing Confirms Network Compatibility
According to officials familiar with the project, the recent trials demonstrated that D2M broadcasts can coexist with mobile telephony services while maintaining uninterrupted access to essential communication functions. During testing, voice calls and text messaging were given priority, ensuring that active multimedia broadcasts did not interfere with critical mobile services.
The positive outcome is being viewed as a major milestone for the project, as it removes one of the last significant technical challenges before large-scale implementation. Authorities are now focusing on the next phase of planning and execution.
Detailed Project Report Under Review
Sources said that Prasar Bharati is in the process of finalizing a Detailed Project Report (DPR), which will serve as a comprehensive framework for the rollout of the technology. The report is expected to outline implementation strategies, governance structures, funding mechanisms, and risk management plans designed to support long-term sustainability.
Once the DPR receives the necessary approvals, a Request for Proposal (RFP) will be issued, enabling the project to move toward commercial and public deployment. Officials indicated that project structuring efforts are also underway to attract investment and establish a legally compliant operational model.
Government Agencies Participated in Trials
The field demonstrations were conducted in March around Kartavya Path with participation from multiple government bodies, including the Ministry of Information and Broadcasting, the Ministry of Electronics and Information Technology, and the Indian Institute of Technology (IIT) Kanpur. The collaborative exercise helped evaluate the technology under real-world conditions and validate its operational performance.
Officials noted that the project management consultant, Ernst & Young (EY), has already submitted the DPR to Prasar Bharati. The document has subsequently been forwarded to the Ministry of Information and Broadcasting for further examination and consideration.
How D2M Technology Works
D2M broadcasting enables the direct transmission of multimedia content to compatible mobile devices through terrestrial broadcast infrastructure. The system can deliver live television channels, audio services, emergency notifications, educational content, and other data services without relying on internet connectivity or Wi-Fi networks.
To access these services, users will require devices equipped with specialized hardware capable of receiving and decoding broadcast signals. Since the technology does not depend on internet bandwidth, it can potentially provide a more stable viewing and listening experience, particularly in areas with inconsistent network connectivity.
Development Journey Began Years Ago
The initiative traces its origins to a memorandum of understanding signed between Prasar Bharati and IIT Kanpur in 2019. The partnership was aimed at developing a future-ready roadmap for digital terrestrial broadcasting aligned with evolving technological standards.
Following extensive analysis of available broadcast technologies, IIT Kanpur conducted an early proof-of-concept trial in Bengaluru to evaluate feasibility. Additional pilot tests were later carried out in Delhi, Noida, Bengaluru, and other locations to assess performance across different environments.
Potential Benefits for Consumers and Networks
Industry officials believe the technology could play an important role in reducing congestion on mobile networks, particularly during high-demand events such as major sporting tournaments and large-scale live broadcasts. By shifting video and audio distribution to broadcast infrastructure, telecom networks may experience reduced traffic loads.
The system could also lower content access costs for consumers by reducing dependence on mobile data plans, making multimedia services more accessible while improving overall network efficiency.
