Tejas Networks and Intel integrate D2M Technology into Laptops for educational content delivery

Tejas Networks and Intel have collaborated to integrate Direct-to-Mobile (D2M) technology into Intel-powered laptops, enabling the delivery of multimedia educational content without internet connectivity. The announcement was made ahead of the World Audio Visual & Entertainment Summit (WAVES) 2025.
D2M, a broadcasting technology developed through a proof-of-concept at IIT Kanpur, utilizes terrestrial TV broadcast airwaves to transmit live TV, video, audio, and text messages, including educational programming and emergency alerts, to mobile phones and computing devices without requiring Wi-Fi or internet service. The technology leverages the multicast architecture of ATSC 3.0 to deliver diverse educational content tailored for different grades, school boards, or languages, particularly in areas with limited connectivity.
The integration involves Intel processors, an embedded antenna, and Tejas Networks’ Saankhya SL-3000 SDR chipset, which has been tested in live networks by Prasar Bharati in partnership with IIT Kanpur and Tejas Networks. Tejas Networks has also developed infrastructure hardware and software for D2M network deployment, supporting the initiative’s alignment with India’s “Design in India” and “Make in India” efforts.

The SL3000 is an SDR (Software Defined Radio) chipset developed by Saankhya Labs. It's ...
