Direct-to-mobile (D2M) technology

About Direct-to-mobile (D2M) technology

• The science behind D2M is similar to that of an FM radio, where a receiver within the device can tap into different radio frequencies.
• This new-age technology is a combination of broadband and broadcast that uses mobile phones to capture territorial digital TV signals.
• Using D2M, multimedia content, including live TV matches, can be streamed to phones directly without using the internet. 
• D2M can ensure-
  • Emergency alerts are delivered directly, reliably and without dependence on internet/cellular networks. 
  • Disaster Management audio content is delivered directly and authentically in a targeted manner.
  • With D2M, governments can broadcast citizen-centric information.
  • This approach benefits consumers by reducing their reliance on internet data consumption for staying informed and entertained.
• Challenges involved 
  • It is still in the development stage.
  • The biggest challenge in front of the government is to bring different stakeholders, including telecommunications, on board in launching D2M tech on a wide scale.
