What is D2M Technology How Can You Watch Videos Live TV Without Internet connection Explained

Mobile users will soon be able to stream video without a SIM card or internet connection, as direct-to-mobile broadcasts may become a reality. The central government says that the trial of domestic direct-to-mobile (D2M) technology will soon be conducted in 19 cities. Shifting 25-30 percent of video traffic to D2M will also remove bottlenecks in 5G networks. However, what is this D2M technology and how can a person stream video or live TV on his mobile without a SIM card or internet connection? Let us know.

In June last year, IIT-Kanpur in collaboration with Prasar Bharati and Telecom Development Society on D2M broadcasting white paper Was released, in which everything about it is explained in detail. This technology has been developed by Saankhya Labs and IIT Kanpur. In a letter in August 2023, the Communications Ministry also listed its use cases. It was told in which areas this technology can be used in the near future.

What is D2M technology?

D2M technology works in a similar way to FM radio, where a special receiver inside the phone can pick up a special radio frequency that carries D2M content. D2M is a combination of elements of broadband and broadcast technologies. Mobile phones can capture terrestrial digital TV signals using a dedicated antenna.

Information and Broadcasting Secretary Apoorva Chandra according tothe government will reserve 470-582MHz spectrum for this emerging technology.

According to the released paper, this technology will give users access to a wide range of multimedia content directly on their smartphones and tablets, bypassing traditional broadcast methods. This can include live TV channels, educational programs, citizen-centric information, emergency alerts, and even entertainment content like movies and music.

The technology will prove to be very beneficial in areas where network coverage is very low or internet is expensive.

Additionally, broadcast will use a different spectrum than mobile data, leaving bandwidth available for other uses.

What benefits will we get from this?

The government says that this technology will benefit both smartphone users and telecom operators. D2M technology will help shift 25-30% of video traffic to closed 5G networks, thereby helping to accelerate digital growth and democratize content distribution in the country.

Furthermore, it has also been said by the government that 69% of the content accessed by users on the 80 crore smartphones in India is in video format. Apart from serving those who have other devices like TVs, this technology will help reach about 8-9 crore “TV dark” homes across the country.
