Viasat demonstrates D2H satellite communication technology
Viasat has performed the first successful direct-to-handset (D2H) communication test using direct-to-device (D2D) technology in L-band in Brazil.
The demonstration showcased two smartphones connecting directly via satellite using 3GPP NTN standards without the involvement of other terrestrial infrastructure. This signifies the start of a new age of connectivity in the country where only about 18% of the geographic area is covered by cellular networks, according to Anatel data published in September 2024.
The event, held in the nations capital, was attended by officials from Anatel (Brazilian National Telecommunications Agency), and representatives from the government, telecommunications sector, and partners. The demonstration focused on two primary scenarios in which D2D technology was utilised: direct-to-handset communication and data transmission for Internet-of-Things (IoT) devices in the agricultural and transportation sectors, with plans for expansion into additional markets.
Leandro Gaunszer, General Manager, Viasat Brazil, said: 'This demonstration is a significant achievement for connectivity in Brazil. It shows that reliable primary satellite communications over smartphones and IoT applications are far more available, opening the door for a future where technology will help build the bridge to the unconnected and make it available to a wider range of individuals and companies, regardless of where they are located. Our extensive L-band coverage and alignment of satellite technologies with 3GPP standards provide a strong foundation for introducing this groundbreaking solution to the country. This will contribute to the development of a more inclusive, interconnected, and effective community and network for both consumers and businesses.'
