Network Stability Protection
Chunghwa Telecom, the leading integrated telecommunications service provider in Taiwan, has long been committed to the construction, operation, and maintenance of communications networks, supporting the stable operation of nationwide fixed-line, mobile, and international telecommunications services. The Company plays a critical role as a key provider of both domestic and international communications infrastructure.
Building on this foundation, Chunghwa Telecom continues to strengthen the security and resilience of critical telecommunications infrastructure. Through diversified transmission routes, redundant architectures, and cross-region resource allocation mechanisms, the Company enhances network resilience and response capability in the event of equipment failures, natural disasters, or other unexpected incidents.
These efforts integrate multi-layer communications resources, including terrestrial networks, submarine cables, microwave systems, and multi-orbit satellite communications. By coordinating upstream and downstream resources and adopting a regional joint defense operating model, the Company advances overall network resilience as part of a comprehensive infrastructure strategy, ensuring the continuous operation of core communications services.
Information Equality Protection
To ensure information equality, we not only actively enhance the quality of mobile network services in densely populated urban areas, but also place equal emphasis on signal coverage in rural areas.We have achieved 100% 4G coverage across all Administrative regions of Taiwan.
In addition, we proactively respond to the national policy target of “2 Gbps network coverage reaching 90% by 2025” and “Smart Nation Program” (DIGI+) for equal development opportunities to all citizens to inspire innovative applications of digital economy, and complete ultra-broadband network construction in the rural areas. As of 2025, 2Gbps network coverage reached 90.33%, while 1Gbps network coverage reached 94.3%.
Free Wi-Fi Access for All
Chunghwa Telecom has been proactively assisting the government in promotion of free Wi-Fi access for all. With a robust platform and 24/7 maintenance and monitoring system, Wi-Fi hotspots are deployed nationwide to suppert the government in achieving the goal of “Free Wi-Fi Access for All.”
No Lone Island in Rural Communications
Aside from the active efforts in network construction, we also stress on the mobile communication quality in the rural areas. The redundant trunks and redundant wireless routers are added and boosted constantly in the rural areas; the capacity of backup power supplies is elevated; the redundancy of resilient platforms is raised to 72 hours or above, so that the rural areas will not lose connections with the outside world owing to power outage from natural disasters.

Network Outage Incidents and Response Measures
The Company is committed to building highly resilient critical infrastructure. When faced with occasional network disruptions caused by external construction damage, natural disasters, or system upgrades, we activate emergency response immediately. Through measures such as establishing physical dual-route redundancy, adding bypass circuits, and strengthening pre-construction engineering risk assessments, we continuously enhance our nationwide network protection framework.
