D2M stands for Direct To Mobile Broadcasting Technology. With this technology, viewers can watch live TV programs on mobile without internet access. The Indian government is planning to introduce this technology in 19 cities in India on a large scale as soon as possible.
About this technology, Information and Broadcasting Secretary Apoorva Chandra has said on Tuesday, ‘This technology developed in our country will soon be piloted in 19 cities, last year pilot attempts were conducted in places like Bengaluru, Noida and Kartavya Path.
What is Direct to Mobile (D2M) Technology?
With this technology it is possible to transmit multi-media content directly to mobile without any active internet connection, just like broadcasting programs directly on TV and radio.
As announced by the Ministry of Information and Broadcasting, it has been mentioned that with this technology, real time content can be delivered to the mobile in a hybrid broadcast manner.
How does this D2M technology work?
Earlier this technology was used to send natural disasters or warning notices. D2M technology is said to work almost like D2H. For example, this D2M technology is said to work in the same way as a radio can broadcast programs using a transmit signal through frequency.
IIT Kanpur Study Report:
In the research report published in the year 2022 at Kanpur IIT titled ‘D2M Broadcast 5G Broadband Convergence Roadmap for India’, it has been reported that this D2M technology will not work in the mobile phones currently sold in India.
Mobile devices require a separate baseband processing unit to function. This is said to increase the cost of mobiles and affect the LTE and 5G networks currently in use.
Challenges in Integrating D2M Technology into Mobile:
This D2M network is known to operate in the 526MHz-582MHz band. Also, experts believe that the antenna size for this would be a bit large and integrating it into existing smartphone designs would be a challenging task.
