Land-Sea-Air Full-Dimensional Satellite-Terrestrial Integration
Taiwan Mobile participated in the 2026 Taiwan International Space Annual Conference held November 8 to 10, featuring land, sea, and air full-dimensional satellite-terrestrial integration and sharing its integrated layout of satellite communications and terrestrial mobile networks. Taiwan Mobile used the conference to deepen exchanges with domestic and international satellite operators, track technology developments and field-site needs, jointly explore service integration, application validation and commercial cooperation opportunities, and prepare in advance for diversified enterprise communications needs.
Direct-to-Cell Satellite Technology Validation
Taiwan Mobile is Elveo Mobile's first allied telecom operator in Taiwan. The two sides have cooperated since March 2024, and in November of the same year completed SMS exchange and voice calls via direct-to-satellite connection using ordinary mobile phones at the same location. In September 2026, they further completed a ground station resilience backup test in northern Taiwan, sending SMS via Elveo LEO satellites for reception by an overseas ground station and return to Taiwan, successfully validating the feasibility of space-based base stations with cross-border ground station backup, and continuing to build non-terrestrial network technology and practical experience.
In addition, Taiwan Mobile signed a strategic memorandum of understanding with AST SpaceMobile for LEO satellite communications services during MWC in March this year, advancing standard direct-to-cell satellite technology and expanding its satellite-terrestrial integrated communications footprint.
Multi-Orbit Satellite Maritime Solution
For multi-orbit satellite integration, Taiwan Mobile has partnered with Xiangyu Group, which has cultivated the international satellite communications market for over 30 years, to build a one-stop maritime satellite communications solution, combining OMNISAT multi-orbit satellite equipment researched, developed and manufactured in Taiwan by Zhengyu Microwave under Xiangyu Group authorization, to jointly promote satellite-terrestrial integrated applications. The system can integrate OneWeb, Starlink and Iridium LEO satellites, SES GEO satellites and Taiwan Mobile 4G/5G terrestrial mobile networks, with plans to include MEO satellite resources in the future, reducing the impact of a single-network outage through link selection, bandwidth aggregation and handover.
Targeting Enterprise Resilient Communications Needs
Taiwan Mobile Enterprise Services Chief Business Officer Zhu Xiaoxing said that in recent years enterprise operations have extended to maritime, remote and other field sites, with disaster response and critical-facility backup needs continuing to grow. Taiwan Mobile is building a three-dimensional communications sky-net with land, sea, and air full-dimensional satellite-terrestrial integration, using satellites and terrestrial networks to complement each other and fill coverage gaps in remote areas, at sea, and in disaster or emergency scenarios, creating stable, disaster-resilient communications infrastructure for government and enterprises.
In the future, Taiwan Mobile will continue to integrate international satellite resources with terrestrial network advantages, extending satellite-terrestrial integration capabilities to maritime, energy and critical infrastructure and other diversified field sites, providing satellite solutions covering networks, equipment, system integration and follow-up operations and maintenance, helping enterprises overcome geographic limitations and improve communications resilience.
