Smart Communications and Lynk Global have expanded tests of direct-to-device (D2D) satellite connectivity to Batangas, examining how the technology could provide emergency communications when terrestrial mobile networks are disrupted by disasters.
The latest trials follow earlier tests in Catanduanes and Ilocos Norte and focused on using satellites to deliver communications directly to standard mobile phones in areas where cellular infrastructure is unavailable or temporarily knocked offline.
Smart and Lynk simulated disaster scenarios involving disrupted network infrastructure and tested satellite-enabled cell broadcasts for sending emergency alerts and public safety messages directly to mobile users in affected communities.
The companies are also testing two-way communications, including the ability to send SMS messages through satellites when terrestrial cell towers are unavailable because of typhoons, power outages or other disruptions. The technology could also extend coverage to rural and hard-to-reach locations, including maritime areas.
D2D satellite technology is designed to connect satellites directly with existing mobile phones, potentially providing a backup communications layer without requiring users to carry dedicated satellite handsets.
“Reliable communication is essential in times of crisis. As disasters continue to pose challenges to communities across the country, PLDT and Smart remain committed to investing in technologies that help ensure critical information reaches people when they need it most,” said Menardo G. Jimenez Jr., PLDT chief operating officer and network head.
“For us, this goes beyond technology. 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 added.
The Batangas trials build on Smart and Lynk’s D2D tests in Catanduanes and Ilocos Norte, where the companies similarly examined how satellite connectivity could complement existing telecommunications infrastructure in remote and underserved locations.
