Tunnel Communications Systems
For above-ground communication, we are spoiled for choice when it comes to available technology, but these matters become more complicated underground. Tunnel communication systems cannot rely on satellites, and tracking cannot be done utilizing GPS, but workers need to communicate and operations need to be monitored.

Buy Underground Mine Phones and Mining Telephone Systems
Personnel in mining operations typically need to communicate over long distances, often in challenging underground environments. That’s where underground mine phones, also known as mining telephones or mine phone systems, come into play. They’re a vital part of creating a safe, efficient, and productive workplace.

Essential Safety Equipment for Trenchless Tunneling Projects
Trenchless tunneling has transformed the way underground infrastructure projects are carried out, offering a safer, faster, and more efficient alternative to traditional open-cut methods. However, despite its advantages, trenchless technology still poses significant risks, and worker safety should remain a priority.
From mines and tunnels to trenchless construction sites and emergency rescue operations, Sybet’s portable communications systems enable secure, wireless voice communication and tracking without the need for pre-installed infrastructure. Whether you’re conducting routine maintenance or responding to a life-threatening incident, Sybet systems are engineered to deliver fast deployment, extended operational time, and absolute reliability.
Why Portable Underground Communications Systems Matter
In underground worksites, especially during rescue operations, there is no time to waste installing cables or permanent communication lines. Immediate communication between underground teams and the surface is essential not just for efficiency, but for survival.
Sybet systems are uniquely suited for:
- Mine rescue operations
- Tunnel maintenance and exploration
- Trenchless and utility construction
- Cave or viaduct inspections
- Any scenario lacking fixed underground-to-surface infrastructure
Their plug-and-play design and battery-powered nodes enable rapid setup in even the most challenging environments.
Tailored Communications Systems for Different Underground Challenges
Sybet offers several advanced systems, each suited for different underground applications:
SWAR-2EX System
Designed for mine rescue and emergency response, the SWAR-2EX creates a temporary wireless communication network using a series of portable battery radio nodes and radiotelephones. It supports voice communication, position tracking, and network health monitoring. A fully charged node can operate for up to five days, providing uninterrupted connectivity during long-duration missions.
SpellCom System
Ideal for cave systems, dam inspections, or other confined underground spaces, SpellCom uses compact MiniNodes to create a scalable radio network. It supports localization, phone tracking, battery-level monitoring, and can be expanded to suit both small-scale and large-scale deployments.
With support for ATEX and IECEx-certified devices, Sybet systems meet international safety standards for explosive atmospheres, making them a trusted choice for hazardous mining environments.
Every Rescue Team Should Be Equipped
Communication is the backbone of any rescue effort. In situations where lives are on the line and infrastructure is damaged or absent, Sybet systems provide the only portable communication solution capable of linking underground personnel with surface teams in real-time. Deploying a Sybet network can be the difference between delay and rescue.
That’s why every mine rescue team should have immediate access to a Sybet system and a sufficient number of nodes, ready for deployment whenever an emergency arises.
