A Dedicated ‘Fast Lane’ for Mission-Critical Communications

High-speed broadband powers everyday life, from streaming movies to navigating traffic in real time. But when disaster strikes and everyone jumps online, that same network becomes crowded, slowing down access for the people who need it most: first responders.

Two47 MCX from L3Harris was purpose-built to change that. It gives first responders their own prioritized, secure broadband connection, ensuring fast, reliable access to the communication networks that’s widely available. While typical broadband network access can fail them, Two47 MCX ensures first responders stay connected.

James Potter, Director of Product Management, L3Harris, describes the Two47 MCX advantage with a rush-hour traffic analogy: a broadband network is the highway, and each cellphone user is a car; when first responders are using the same lanes of traffic as all the other users, they are at the will of the network to move forward. MCX provides emergency officials a dedicated “fast lane” of travel to prioritize public safety operations.

Whether it’s the ability to leverage broadband and P25 networks nearly simultaneously or to use Mission-Critical Push-to-Talk (MCPTT), MCData and MCVideo, Two47 MCX transforms everyday devices into versatile mission-critical tools. MCData provides the ability to push text, file transfers and GPS locations through push-to-talk functionality, and MCVideo allows users to establish talk groups to share video for situational awareness. The Mission Critical Services (MCX) open standard was developed by the Third Generation Partnership Project (3GPP), the same organization to create standards for LTE, 5G and 6G.

Breaking Down Communication Barriers

The L3Harris Two47 MCX eliminates communication barriers by seamlessly unifying teams, devices and networks. Built on open, globally trusted 3GPP standard assures users of seamless integration between radios, smartphones and personal computers so teams across varied environments can stay connected without interruption.

“Bridging LMR and broadband networks provides smooth transitions between legacy and modern technologies and delivers a robust interoperability that fosters real-time collaboration across public safety, defense, utilities and private sectors,” said Potter. “This enables multi-agency and cross-industry connectivity without limits.”

The L3Harris MCX Advantage

MCX applications are broad, from application-based capabilities that can be installed on smartphones to browser-based platforms for personal computers. The L3Harris MCX advantage is the full integration into the company’s XL series of radios.

“We deliver MCX capabilities in a form factor trusted by public safety organizations all over the world,” said Potter. “Two47 MCX ensures your communications remain reliable, resilient and secure even under the toughest conditions.”
In an APCO 2024 presentation, Capt. Brian Screws, Chief Information Officer for the Georgia State Patrol, described converged devices as “access to a new network that brings a lot of new technology to our agency.”

Said Screws, according to Urgent Communications: “What really made the difference was, once we saw the marriage of both worlds—connect the XL series of radios to combine the worlds of broadband, along with our P25 systems scattered around the state. When we can merge those together, it really gave us a silver bullet.”

L3Harris’ Two47 MCX also protects sensitive transmissions from unauthorized access and cyber threats while providing geo-redundant and high-availability deployment options to reinforce operational reliability, added Potter. Uninterrupted functionality in crisis scenarios ensures mission-critical traffic is prioritized within the system for preemptive performance even while competing with network congestion.

Available Today and Gaining Ground

L3Harris Two47 MCX capabilities are available today and scale effortlessly to meet the demands of any operation, no matter the size or scope, according to Potter. MCX is a global standard helping organizations evolve their communication systems without overhauling their infrastructure.

In the utility sector, many regional providers have made significant investments in private broadband infrastructure. These networks offer a strong foundation for integrating MCX capabilities, enabling utilities to prioritize broadband access and enhance their ability to coordinate across wide service areas. Through collaborations with L3Harris, utilities are exploring how to use both public and private networks to support grid stability, field operations, and rapid response during emergencies – and the opportunities continue to grow.

“Whether deploying localized teams or managing nationwide networks, Two47 MCX offers flexible configurations ranging from turnkey deployments to custom-built solutions tailored specifically to operational requirements,” said Potter. “It’s simplified user provisioning and management tools allow administrators to onboard users and manage groups with ease for smooth operation even across multiple organizations.”
