BSNL and Viasat Trial Direct-to-Device Satellite Connectivity
Satellite communications company Viasat has successfully demonstrated direct-to-device (D2D) satellite connectivity in India for the first time. In partnership with Bharat Sanchar Nigam Limited (BSNL), Viasat showcased satellite-powered two-way and SOS messaging using a commercial Android smartphone at the ongoing India Mobile Congress 2024, the companies said in a joint statement on Tuesday. Viasat said it is currently working with its partners, including BSNL in India, to expand satellite services for consumer and IoT devices worldwide.

First D2D Satellite Connectivity in India

During the trial, Viasat demonstrated two-way and SOS messaging on a commercial Android smartphone enabled for non-terrestrial network (NTN) connectivity. The messages were transmitted over approximately 36,000 km to one of Viasat’s geostationary L-band satellites.

“The outcome proves that satellite services for cell phone connectivity are technically feasible for Indian consumers and businesses using Viasat’s satellite network,” the official release said.

Direct-to-Device (D2D) Connectivity

Viasat explained that direct-to-device connectivity is a new technology that allows everyday devices—such as mobile phones, smartwatches, or cars—industrial machinery, and transport operators to connect seamlessly to both terrestrial and satellite networks. This enables devices to stay connected from any location without requiring dedicated satellite hardware.

Connectivity Without Dedicated Hardware

According to Viasat, this achievement underscores the feasibility of connecting smartphones directly to satellites without the need for additional hardware.

The technology follows global 3GPP Release 17 standards, which are being adopted by satellite operators, mobile network operators, and handset and chipset manufacturers.

Commenting on the demonstration, Viasat said, “It is exciting to be showcasing the potential for direct-to-device in India, where D2D could help reduce barriers to accessing satellite connectivity – particularly in India where millions do not have access to reliable terrestrial connectivity.”

“In the future, D2D could help transform the Indian production and supply chain to become more efficient, more sustainable and safer, and support automotive applications to enhance safety and conditions-based maintenance.”

BSNL and Viasat Partnership

Viasat added, “Together with partners like BSNL, Viasat is driving a standards-based, open, transparent, collaborative D2D ecosystem to deliver seamless connectivity experiences no matter where a person, device, or vehicle is.”

The Chairman and Managing Director of BSNL said, “BSNL, in an exclusive partnership with Viasat, is proud to lead Direct-to-Device innovation. Today’s successful demonstration, the first in India, showcases the potential to enhance direct communications for critical services, disaster recovery, and even rural connectivity across India using the BSNL network and Viasat’s L-band satellite constellation.”
