Cybertel and its subsidiary TWnC have been awarded the operation and maintenance (O&M) contract for Korea’s nationwide public safety communication network, SafeNet, reinforcing their role in supporting mission-critical communications infrastructure across the country.

SafeNet is Korea’s nationwide public safety LTE (PS-LTE) network designed to enable seamless interoperability and coordinated communications among public safety agencies during disasters, emergencies, and large-scale incidents. Since its official nationwide launch in May 2021, SafeNet has become a core mission-critical communications platform supporting more than 230,000 field devices and hundreds of public safety organizations across Korea.

The SafeNet infrastructure incorporates advanced mission-critical communication technologies, including Mission Critical Services (MCX) and evolved Multimedia Broadcast Multicast Service (eMBMS), enabling stable and efficient group communications even during high-density emergency response operations.

The network has already demonstrated the capability to support mission-critical group communications for approximately 15,000 public safety personnel operating simultaneously within the same area, highlighting the scalability and resilience of Korea’s national emergency communications infrastructure.

Under the newly awarded contract, Cybertel and TWnC will provide nationwide operation and maintenance support for SafeNet through March 2029.

As part of the project scope, Cybertel will oversee Help Desk operations and provide Speech-to-Text (STT) solutions to enhance frontline user support, operational efficiency, and voice-based record management for public safety agencies.

Meanwhile, TWnC will manage core network operations, network performance monitoring, cybersecurity monitoring, inter-agency integration support, and overall operational management to ensure nationwide service continuity, network reliability, and infrastructure security.

Scope of Support

• SafeNet operation and maintenance services through March 2029

• Core network operations and nationwide security monitoring

• Help Desk support for public safety personnel

• STT (Speech-to-Text) operational support solutions

• MCX-based mission-critical communication maintenance

• Nationwide public safety communications operational management

The SafeNet project further strengthens the companies’ expertise in nationwide mission-critical network operations and advanced public safety communication services.

The operational experience gained through SafeNet O&M, MCX service maintenance, STT-enabled operational support, and nationwide core network management is expected to support future development of 5G-based Public Safety Networks (PSNR) and next-generation emergency communication systems.

As public safety communications continue evolving toward AI-assisted operations, intelligent network management, and next-generation mission-critical services, Cybertelbridge aims to further expand its role as a trusted technology partner delivering resilient, secure, and future-ready communications infrastructure for public safety agencies worldwide.
