Kirisun Unveils the TD80: A New Era in Mission-Critical 5G Communications

In mission-critical operations across public safety, firefighting, electricity, port logistics, and airport management, seamless real-time connectivity is not a luxury — it is an absolute necessity. The TD80 from Kirisun is a 5G dual-mode MCX smart terminal engineered to deliver uncompromising performance, robust security, and versatile connectivity in the world’s most demanding industrial environments.

The Power of Dual-Mode: 5G NR Meets 450MHz LTE Private Networks
The defining capability of the TD80 is its unique dual-mode architecture, fully compliant with 3GPP Release 15. Unlike conventional rugged smartphones that rely solely on public cellular infrastructure, the TD80 simultaneously supports commercial 5G NR networks and dedicated 450MHz LTE private networks (Bands 31 and 72).

This dual-access design fundamentally transforms operational connectivity. The 5G NR radio delivers ultra-fast broadband for high-definition video streaming, real-time situational awareness, and bandwidth-intensive mobile applications. Meanwhile, the 450MHz LTE transceiver provides unmatched coverage penetration — its sub-1 GHz signals propagate farther, penetrate deeper into buildings and underground structures, and maintain reliable links in remote rural areas where higher-frequency networks simply cannot reach. For organizations deploying private LTE networks at ports, power plants, airports, and industrial facilities, the TD80 offers a direct, secure gateway into their exclusive spectrum — free from public network congestion and entirely under their operational control.

Complete MCX Ecosystem Support with Sub-40 ms Latency
Where the TD80 truly distinguishes itself is in its deep integration with standard MCX (Mission-Critical Services) platforms — the 3GPP-defined successor to traditional PMR systems. The device delivers full support for QoS Class Identifiers spanning QCI 1 through 65, 66, 69, and 70, with Mission-Critical Service Priority (MSP) latency as low as 40 milliseconds.

In practical terms, this means emergency push-to-talk calls, priority video streams, and lifesaving data transmissions are granted guaranteed network resources the instant they are initiated — even when the network is under maximum load. This granular, standardized prioritization framework enables seamless interoperability between agencies and across borders, making the TD80 an ideal choice for coordinated multi-agency emergency response, cross-jurisdictional public safety operations, and any organization where communication failure is not an option.

Large-Screen Intelligence Built for the Field
The TD80 pairs its formidable radio architecture with a purpose-built rugged design centred around a 4.7-inch Full HD display protected by Corning Gorilla Glass 3. The screen is engineered for glove and wet-hand operation — a seemingly small detail that becomes critical when first responders are wearing protective equipment or working in adverse weather. A dedicated 0.96-inch top screen provides at-a-glance status information without activating the main display, preserving battery life during extended field operations. At the core lies a 6nm Qualcomm chipset with 8 GB RAM and 128 GB ROM, delivering desktop-class performance for demanding mobile applications.

Transforming Mission-Critical Industries Worldwide
The TD80 is purpose-built for professionals who cannot afford to lose connectivity when it matters most. In public safety, officers gain instant access to mission-critical push-to-talk, live video streaming to command centers, and secure biometric-protected data access — all with sub-40 ms priority handling over MCX networks. Firefighters benefit from glove-friendly touchscreen operation in smoke-filled environments, 4K night-vision video documentation, and a 102dB loudspeaker that cuts through roaring flames and sirens.

Electricity utilities leverage its 4W high-power transmitter and multi-constellation GNSS positioning for field crews maintaining critical grid infrastructure in remote coverage-challenged areas. Port and airport operators depend on its dual-SIM flexibility and comprehensive global band support to coordinate ground personnel across vast logistics hubs spanning both public cellular and private LTE networks. With IP68 ingress protection, 1.5-metre drop resistance, and a 7,600mAh battery delivering shift-long endurance, the TD80 is built to survive the conditions that destroy ordinary devices.

Looking Ahead: Expanding into Hazardous Environments
The standard TD80 is wedding to release, but Kirisun’s innovation roadmap does not stop here. An explosion-proof variant of the TD80 is scheduled for release by the end of this year, bringing the same 5G dual-mode, MCX-ready, and mission-critical capabilities into hazardous environments. The explosion-proof variant release will empower professionals in oil and gas, petrochemical, pharmaceutical, and mining industries with the same uncompromising connectivity and safety that the TD80 delivers today.

The TD80 is more than a communication device — it is a strategic platform for organizations that demand the highest standards of reliability, security, and performance. For those who protect, power, and move the world, the future of mission-critical communications starts here.
