Smart Communications Inc. has made significant progress in its efforts to expand mobile coverage in the country through satellite connectivity after completing tests that demonstrated its reliability despite the impact of storms and other disasters.

Smart said in a statement on Wednesday, Aug. 19, that it successfully completed the latest test of its direct-to-device satellite service in Batangas, which was conducted under simulated disaster scenarios.

Through its partnership with satellite internet provider Lynk Global Inc., Smart said the demonstration showed that satellite connectivity remains reliable in areas where network infrastructure may be temporarily disrupted following a calamity.

In particular, satellite-enabled cell broadcasts were found capable of delivering emergency alerts and public safety messages to customers, which are crucial for the government during critical situations.

The technology was likewise capable of two-way communication, such as sending text messages, in a scenario where terrestrial cell towers become unavailable.

Menardo Jimenez, chief operating officer of PLDT, said the direct-to-device satellite service helps ensure that there is still reliable communication when people need it most.

“Our mission at PLDT is to be there for all Filipinos, whether they are talking to family abroad, or requesting for assistance from a rooftop in the middle of a calamity,” he said.

The latest trial of the service builds on tests conducted in Catanduanes and Ilocos Norte earlier this year, which focused on how satellite technology can complement existing telco infrastructure in remote and underserved areas.

Smart said in January that tests would continue across more areas and diverse use cases as Lynk’s satellites continue to be deployed and service availability improves further.

Lynk operates so-called “cell-tower-in-space” satellites that provide direct-to-device connectivity with continuous global coverage, bringing access to critical services for 90 percent of the world’s population in areas considered “coverage black spots.”

The service is delivered through its mobile network partners across the globe, including Smart in the Philippines, and can connect to any mobile device.

Earlier, Smart said it is targeting a commercial launch of the service in the country next year.

Once the direct-to-device satellite service is fully rolled out within the next few years, the company also plans to integrate full mobile voice and data connectivity as part of the offering.
