How it works
Underground Connectivity With Rajant
Reliable Coverage Underground
Compact BreadCrumb® nodes, deployed on infrastructure or moving assets, form a rugged mesh with built-in redundancy. Multiple radios and frequencies ensure uninterrupted voice, data, and video transmission—even when traditional networks fail.
Extend Reach, Reduce Cost
Paired with wide-band, bidirectional antennas, Rajant’s solution reliably extends connectivity up to 1 km underground—even through bends and corridors. It delivers a cost-effective alternative to fiber while supporting live video, telemetry, worker tracking, and real-time monitoring of tunnel conditions.
Self-Healing for Safety and Efficiency
Powered by InstaMesh®, the system continuously evaluates optimal routing and auto-adjusts in real time. If a path degrades, traffic instantly reroutes via the next-best link—preserving performance and protecting operations from disruptions.

Frequently Asked Questions
What is Rajant Kinetic Mesh® technology?
Rajant Kinetic Mesh® is an Intelligent Edge networking technology designed for dynamic, mobile environments where traditional fixed infrastructure falls short.
Unlike conventional wireless systems, it enables continuous, adaptive connectivity across moving assets, people, and devices. Powering Industrial AI applications that demand resilience, low latency, and real-time decision-making.
How do Rajant’s BreadCrumb® wireless nodes enhance network connectivity?
Rajant’s BreadCrumb® nodes are the building blocks of a self-forming, self-healing Kinetic Mesh® network.
Each node communicates directly with every other, creating a web of redundant, high-throughput connections that ensure uninterrupted communication, even when conditions change or assets move.
This decentralized design eliminates single points of failure, maximizing uptime and mobility.
InstaMesh® vs. conventional point-to-point connections.
Conventional point-to-point networks depend on fixed links that can break under motion or interference.
Rajant’s InstaMesh® routing protocol dynamically reroutes traffic in real time, automatically choosing the fastest, most reliable path.
The result: continuous, mobile, and intelligent connectivity for operations that never stop moving.
What are the benefits of Rajant’s InstaMesh® for IIoT applications?
For Industrial IoT environments, InstaMesh® provides the low-latency, adaptive communication required to keep machines, sensors, and AI systems synchronized.
It delivers instant data exchange, self-healing reliability, and scalable capacity, empowering predictive maintenance, automation, and autonomous decision-making at the edge.
How can Rajant Kinetic Mesh support real-time tele-operations in mines?
Mining operations depend on remote visibility and control where connectivity is often limited.
Rajant’s Kinetic Mesh® delivers real-time communication and video streaming for tele-remote equipment and autonomous vehicles, even underground.
Its multi-radio BreadCrumb® nodes maintain reliable signal and low latency. Keeping operators safely in control from any distance.
Rajant Kinetic Mesh network vs. traditional WiFi solutions.
Traditional WiFi networks are static, fragile, and reliant on centralized infrastructure.
Rajant’s Kinetic Mesh® replaces those limits with a dynamic, peer-to-peer architecture, where every node acts as both transmitter and receiver.
This ensures continuous, adaptive coverage, ideal for moving assets and mission-critical applications where downtime is not an option.
Discover Rajant’s solutions for tunnel communications.
Tunnels and underground environments are notoriously difficult for wireless communication.
Rajant’s BreadCrumb® nodes create a linear, mobile mesh network that maintains signal integrity through long corridors, curves, and obstructions.
