A growing population, the desire for sustainable transportation and infrastructure systems, and the need to minimize surface disturbance has led to an increase in tunneling and underground construction in urban areas. Underground tunneling projects face a myriad of challenges due to these conditions but also operate in environments that are difficult to deploy network systems within. Complex tunnel layouts inherently lead to obstructions that limit how far wireless signals can travel. As a result, traditional single radio wireless systems cannot function optimally, and fiber is often used to achieve reliable connectivity. Yet, these systems are high cost and difficult to change as tunnel construction progresses. What’s needed is a flexible wireless network purpose-built to overcome range and reliability challenges underground—with rapid, dynamic, and cost-effective deployment. Enter Rajant Kinetic Mesh®.
Rajant’s private wireless network enables fully mobile, mission-critical communications to meet safety mandates for real-time worker communications and tracking while running applications that improve efficiency, enhance overall safety, enable surface condition surveying, and speed tunnel construction.
Rajant—The Network Extending Connectivity and Reliable Communications in Underground Tunneling
Recent advances in tunneling technologies, such as the pressurized face Tunnel Boring Machine (TBM), have allowed for the construction of new underground facilities that were previously impossible due to the Rajant Kinetic Mesh network capacity and mobility in underground tunnels without expensive cabling. BreadCrumb® nodes can be deployed on virtually any structure or asset throughout the tunnel to extend or enhance mission-critical coverage for voice, video, and data communications. This makes the network fully mobile and can mitigate interference and congestion to ensure there are never drops in connectivity and that network range can be extended deep inside the tunnel. Here’s how.
Multi-radio, multi-frequency redundancy to ensure mission-critical reliability
Rajant’s compact BreadCrumb nodes can hold multiple connections over multiple frequencies simultaneously, creating the Kinetic Mesh network that enables high throughput communications throughout tunnels. These nodes can be deployed on both fixed infrastructure and moving equipment, making them ideal during tunneling and underground construction projects.
BreadCrumbs use Rajant’s InstaMesh® networking software to direct traffic over the fastest path(s) among the meshed connections they hold—dynamically working around issues caused by interference, congestion, or outages. If a path becomes unavailable, InstaMesh will dynamically route communications via the next-best available link(s), upholding mission-critical performance…
