Daily Current Affairs : 5-January-2024

In recent times, Indian telecom operators have advocated for the government to conduct spectrum auctions specifically for Direct-to-mobile (D2M) technology services. This innovative communication approach integrates broadband and broadcast technologies, offering a myriad of benefits and potentially transforming how information is disseminated to mobile users.

Understanding D2M Technology

D2M, or Direct-to-mobile, is a cutting-edge communication technology that seamlessly blends broadband and broadcast capabilities. At its core, D2M empowers mobile phones to capture territorial digital TV signals. This unique feature enables the direct streaming of multimedia content, including live TV matches, without relying on internet connectivity. Much like an FM radio, the device’s built-in receiver taps into different radio frequencies, enhancing the user experience.

Benefits of D2M Technology

D2M technology comes with a host of advantages, making it a promising avenue for communication and content delivery. Some notable benefits include:

  • Emergency Alerts and Disaster Management: D2M proves to be a crucial tool for delivering timely emergency alerts and disaster management audio content directly to mobile devices. This can be instrumental in ensuring swift responses during critical situations.
  • Reduced Reliance on Internet Data: By leveraging territorial digital TV signals, D2M significantly reduces the dependency on internet connectivity for content streaming. This is particularly advantageous in areas with limited internet access, providing a reliable alternative for accessing information.
Distinguishing Broadband from Broadcast

It is essential to distinguish between broadband and broadcast to comprehend the uniqueness of D2M technology:

  • Broadband: Involves high-speed internet access, facilitating two-way data transmission. It is interactive, allowing users to send and receive data seamlessly.
  • Broadcast: Entails a one-way transmission of content, such as TV or radio signals, to a broad audience. Unlike broadband, broadcast is typically unidirectional, serving as a traditional means of disseminating information.
Important Points:
  • D2M Technology Overview:
    • Innovative communication approach combining broadband and broadcast.
    • Enables mobile phones to capture territorial digital TV signals for direct streaming of multimedia content without internet connectivity.
    • Similar to an FM radio, with a built-in receiver tapping into different radio frequencies.
  • Benefits of D2M Technology:
    • Emergency Alerts and Disaster Management:
      • Critical for delivering timely emergency alerts and disaster management audio content directly to mobile devices.
      • Enhances swift responses during critical situations.
    • Reduced Reliance on Internet Data:
      • Significantly decreases dependency on internet connectivity for content streaming.
      • Provides a reliable alternative in areas with limited internet access.
  • Distinguishing Broadband and Broadcast:
    • Broadband:
      • Involves high-speed internet access, enabling two-way data transmission.
      • Interactive nature allows users to send and receive data seamlessly.
    • Broadcast:
      • One-way transmission of content (TV or radio signals) to a broad audience.
      • Typically unidirectional, serving as a traditional means of disseminating information.
Why In News

Indian telecom operators have fervently urged the government to swiftly conduct the auction for spectrum dedicated to Direct-to-mobile (D2M) technology services, emphasizing its critical role in advancing digital connectivity across the nation.
