Mutualink Restores Interoperable Communications Across CNMI Following Super Typhoon Sinlaku

Two engineers and three Compact Go-Kit 2.0 units were deployed to Saipan, Tinian and Rota in the wake of one of the strongest early-season tropical cyclones on record, working alongside FirstNet, CISA, FEMA and CNMI HSEM to re-establish radio, voice, video and data interoperability across the territory.

The Commonwealth of the Northern Mariana Islands has restored cross-island interoperable communications following the devastation of Super Typhoon Sinlaku, which struck the territory on 14 April 2026 with sustained winds of 150 mph and gusts reaching 185 mph. The storm left Saipan, Tinian and Rota without functioning radio networks, cellular and LTE coverage, or mains power, severely degrading the ability of police, fire, EMS and emergency management agencies to coordinate the response.

Approximately two weeks after the storm, US-based interoperable communications specialist Mutualink deployed two field engineers and three Go-Kits to the territory to operate alongside CNMI Homeland Security and Emergency Management (HSEM) and federal partners already on the ground. The mission was scoped to bridge legacy land mobile radio systems, the FirstNet network as it returned to service, and a satellite-based fallback path designed to keep the system operational in the event of further infrastructure loss.

On Saipan, engineers installed a Go-Kit inside the communications building at the summit of Mt. Tapochao, the highest point on the island and the heart of its radio coverage footprint. The kit was connected to the primary HSEM radio channels in use across Saipan and paired with an IP camera mounted under the roof overhang, allowing HSEM personnel to remotely monitor both the radio equipment and the generator powering the site. The Mt. Tapochao installation runs primarily on Starlink satellite connectivity with FirstNet/LTE as backup.

On Tinian, a Go-Kit was deployed at the Mayor's Office and integrated with the island's primary HSEM radio channel. The site is currently operating on LTE, with Starlink scheduled to come online to deliver the same satellite-resilient backbone now in place on Saipan.

On Rota, where no radios were immediately available for integration at the deployment point, Mutualink engineers configured the Go-Kit's built-in laptop as a software-based dispatch and communications console, enabling the Mayor's Office to reach responders on the other islands directly via the Mutualink network. The Rota site runs on Starlink as primary with LTE as backup.

Beyond the hardware deployment, Mutualink issued LNK360 software licences across the response, including three client installations at the Saipan EOC, additional seats for HSEM ESF-2 staff, the EOC IT Director, CISA and FEMA, and connectivity for the CNMI Department of Public Safety, the CNMI Department of Fire and EMS, and Rota Fire, Police and Hospital personnel. Cross-island talkgroups were established to allow responders on all three islands to coordinate as a single operational team, and HSEM users were trained on platform administration to ensure the capability remains in territory after the engineers depart.

Commenting on the deployment, Mutualink CEO Chrissie Coffey said the response reflected a deliberately layered model of public-private cooperation: "This was never about us showing up with a box. It was about showing up with a capability that fit into what FirstNet, the FirstNet Authority, CISA, FEMA and HSEM were already doing on the ground, and closing the gaps no single partner could close alone."

Coffey added that the territory now has a more durable communications backbone than it had prior to the storm:

"Sinlaku tested every layer of their emergency communications, and it took every layer of their partnerships to bring them back. The result is that the people of Saipan, Tinian and Rota now have a more resilient, more interoperable communications backbone than they had before the storm."

The Mutualink Go-Kit is a portable, ruggedised, all-in-one emergency communications platform engineered for rapid deployment in disaster response, public safety, military, healthcare and critical infrastructure environments. Each unit can interconnect land mobile radio channels, push-to-talk over cellular, voice, video, file sharing and IP camera feeds across agencies and jurisdictions, with built-in support for satellite backhaul, automated network failover and dual-SIM LTE connectivity. The platform is DHS SAFETY Act certified, TAA compliant and eligible for Sourcewell contract procurement.
