What Is D2M Technology? Discover How It Could Revolutionize Mobile Streaming
Quick Answer: What Is D2M Technology?
Direct-to-Mobile (D2M) technology delivers video, audio and data directly to compatible mobile devices using broadcast signals, without requiring an active mobile data connection or Wi-Fi for the broadcast content. It could make live TV, educational programmes and emergency alerts accessible to more people in India.
Unlike conventional streaming, which sends a separate data stream to each viewer, broadcast technology can distribute the same content to many devices simultaneously. However, D2M is not yet a universal feature on existing smartphones, and nationwide consumer availability, device compatibility and service details must be confirmed before users can rely on it.

What Is D2M Technology and Why Is India Exploring It?
Imagine watching a live cricket match on your phone without consuming your daily mobile data allowance. That is one of the possibilities behind D2M technology. D2M combines digital broadcasting with mobile-device reception. India’s public broadcaster, Prasar Bharati, and technology companies have been exploring ways to deliver multimedia content directly to compatible devices.
The potential goes beyond entertainment. D2M could support educational content in areas with limited connectivity and help distribute public information during emergencies.
In an official statement published on 1 April 2026, India’s Ministry of Information and Broadcasting described D2M as a way to broadcast video, audio and data to mobile handsets independently of SIM cards or mobile data.
How Does D2M Technology Work?
To understand the difference, consider how you watch a popular live event today. With conventional mobile streaming, each viewer receives an individual stream over a cellular network. If thousands of people watch the same event in one area, their combined traffic can put pressure on network capacity.
D2M introduces another delivery method: broadcasting common content to many receivers at once.
Here is the simplified process:
- Content preparation: A broadcaster prepares live TV, video, audio or other data for transmission.
- Broadcast transmission: D2M-compatible broadcast infrastructure transmits the content over radio frequencies.
- Signal reception: A compatible phone, receiver or accessory receives and processes the signal.
- Content playback: The device presents the available content without needing a separate mobile-data stream for that broadcast.
The exact implementation depends on the network design, broadcast standard and receiving device.
D2M vs Traditional Mobile Streaming
D2M and streaming are not necessarily competitors. They can complement one another.
D2M Frequency Bandwidth Explained: How Many TV Channels Can It Carry?
One of the most important technical details about D2M technology is the radio-frequency spectrum it uses.
In India, D2M trials have used the 470–582 MHz UHF frequency range. This range spans 112 MHz, but that does not mean a single D2M transmission occupies the entire range.
According to Tejas Networks’ published Broadcast Radio Head specifications, its equipment supports broadcast channel bandwidths of 6 MHz, 7 MHz and 8 MHz. The datasheet lists data rates of up to 25 Mbps for a 6 MHz channel and up to 33 Mbps for an 8 MHz channel.
| D2M specification | What it means |
|---|---|
| Frequency range tested in India | 470–582 MHz |
| Total width of that range | 112 MHz |
| Supported channel bandwidths in Tejas’ datasheet | 6, 7 and 8 MHz |
| Listed data rate at 6 MHz | Up to 25 Mbps |
| Listed data rate at 8 MHz | Up to 33 Mbps |

Can D2M Broadcast Free DD Free Dish Channels?
D2M could potentially deliver free-to-air television content to compatible phones without requiring viewers to use mobile data for the broadcast itself. That makes it relevant to India’s existing free-TV ecosystem.
However, DD Free Dish and D2M are different delivery systems. DD Free Dish is a direct-to-home satellite television platform, whereas D2M uses terrestrial broadcast transmission to reach compatible devices.
D2M could carry selected Doordarshan or other free-to-air programmes if broadcasters make them available through a D2M service and the necessary distribution, spectrum and licensing arrangements are in place. That does not mean D2M automatically receives every DD Free Dish channel.
How Many Channels Could D2M Carry?
The answer depends on the available spectrum, the bandwidth assigned to each transmission, video compression, picture quality, audio requirements and how much capacity is reserved for other data.
For example, a channel carrying compressed standard-definition video generally requires less capacity than one carrying high-quality HD video. A broadcast multiplex can carry multiple services, but the exact number cannot be calculated from the frequency range alone.
D2M’s major advantage is that one broadcast transmission can serve many compatible receivers simultaneously. If thousands of people watch the same live programme, the broadcaster does not need to send each viewer a separate mobile-data video stream.
This could make D2M a useful complement to internet streaming and potentially expand access to free-to-air content—provided the service launches with suitable coverage, devices and a confirmed channel lineup.

Will Your Existing Smartphone Support D2M?
Not necessarily. Having a 4G or 5G smartphone does not automatically mean it can receive D2M broadcasts.
A device needs compatible reception hardware and software for the particular broadcast implementation. Depending on the design, access might require a D2M-enabled phone, a compatible external receiver or another supported device.
In a September 2024 announcement, Tejas Networks’ subsidiary Saankhya Labs and its partners described plans for consumer trials involving smartphones, USB dongles, set-top boxes or gateways, and a low-cost feature phone. That announcement shows the range of device types being explored. It does not establish that all those products are now commercially available. Before buying a new phone or accessory, check for an explicit compatibility statement from the manufacturer or service provider.
Is D2M TV Free in India? What About the Rollout?
D2M could enable free-to-air broadcasts, but free reception does not automatically mean every channel, programme or service will be free. The eventual experience will depend on the broadcaster, content arrangements, coverage and service model.
India has undertaken technical work on direct-to-mobile broadcasting, including trials and research involving compatible devices and transmission infrastructure. In May 2026, ETTelecom reported that Tejas-developed equipment had cleared reported lab and field trials in Delhi. This is an important technical milestone, but successful trials are not the same as a nationwide commercial launch.
Separately, a India Today report published on 30 September 2026 discussed preparations for a possible D2M rollout and an expected Prasar Bharati request for proposals. Any reported procurement timeline should be treated as a reported plan until confirmed by an official announcement.
At the time of writing, readers should not assume that D2M is available across India or that their current phone can receive it. Watch for official updates from Prasar Bharati, the Ministry of Information and Broadcasting, device manufacturers and service providers.
