STRATA CONNECT TRACKING AND COMMUNICATIONS SYSTEM 

What is strata connect?

Introducing the new StrataConnect™ system, an industry-leading mining communication solution designed to provide WIFI connectivity, digital voice and text communication, atmospheric monitoring and tracking capabilities. Using cutting-edge technology, StrataConnect provides an underground communications network (envision a local area network or LAN), which significantly increases operational efficiency and productivity, maintains mine safety and protects valuable assets. And—as the mine advances—the system may be easily extended or relocated to a new area, reducing the time and costs associated with traditional systems.

HOW STRATACONNECT WORKS

The StrataConnect Communication System is made up of wireless access points, a wireless backbone and communications nodes—each of which enables certain features and capabilities.

UNDERGROUND WIFI ACCESS 

StrataConnect’s wireless access points, or A Nodes, provides digital voice calling (within the mine or from mine to surface), texting, data access via computer or mobile device, personnel tracking, asset tracking, atmospheric monitoring and proximity detection monitoring. A Nodes connect to your existing fiber optic and power supply and create underground wireless “hotspots” that function as they would above ground. This is accessible using any standard WIFI-enabled device. 

WIRELESS BACKBONE

The Wireless Backbone, or B Nodes, extends network coverage beyond fiber by serving as a signal repeater. The wireless signal is repeated from one B Node to the next to extend the wireless network throughout the mine. This eliminates the need to lay additional, expensive fiber optic lines to extend functionality and allows for quick and easy deployment. B Nodes may also be used independently to enable a wireless high-speed network in mines where fiber doesn’t exist.

COMMUNICATION NODES

ALSO KNOWN AS COMMTRAC Strata Commtrac is a 100% wireless, mesh communication and tracking system that enables two-way texting, atmospheric monitoring, and tracking of individuals and machinery within 50 feet (15m) or less mine-wide. Because it is 100% battery powered, it remains operational following a mine emergency or power loss. Communication Nodes serve as a self-forming, self-healing routing system that requires no hardwired backbone, allowing easy expansion. Because it is battery powered, the time and costs associated with installation and maintenance are significantly reduced.


Secure servers on-site or at remote locations display a digital mine map on a graphical user interface. Real-time location tracking is plotted on the map, and message activity displayed and logged. Surface operators interact with miners underground via the user interface. Mine maps are easily customized and updated. CommandCenter is a web-based network operations center than links data from multiple mines in one user-friendly interface, allowing one person to oversee operations in one or more mines at a time from a central location. Interact with and track miners and equipment using real-time location tracking with customizable, graphical mine maps. All of the following peripherals operate on StrataConnect.

Safe for coal mining <br>operations and satisfies Program Policy Letter P11-V-13 requiring two-way communications and location tracking in post-accident situations.

Peripherals

WIRELESS ATMOSPHERIC MONITORING

Through a partnership with Trolex, Strata offers intrinsically safe, battery-operated, wireless Atmospheric Monitoring Systems (AMS) to keep miners safe by continually monitoring the working environment and detecting increased levels of CO, CH4, H2S and other harmful gases. Because it is 100% wireless, it is post-accident operational

MINER COMMUNICATORS

These lightweight handhelds function as texting and tracking devices, wirelessly transmitting data from below ground to the surface monitoring interface. Powered by one rechargeable nickel metal hydride (NMH) battery, the Miner Communicators send and receive messages from miner to miner, miner to surface and surface to miner.Tracking data is automatically transmitted to the surface user interface every 30 to 60 seconds (set to customer preference).

TRACKING

 GPS-like tracking, accurate within 50 feet (15m) for both personnel and mobile machinery. A lightweight, compact tracking tag easily attaches to hardhats and provides Intrinsically Safe miner tracking mine-wide. The tracking tag utilizes standard AAA batteries. Similarly, Asset trackers can be attached permanently or magnetically to any mobile equipment and send activity data to the surface. This data not only reports the location of equipment in real-time, but can also be used to calculate mine productivity. Asset trackers utilize standard D-cell batteries.

VOICE-OVER-INTERNET PROTOCOL (VoIP)

Strata handheld VoIP phone provides private, direct dialing with high quality voice <br>clarity and noise cancelation. Communication can be achieved within the mine or from the mine to the surface.Text messaging and Push-to-Talk radio functions also available. StrataConnect is compatible with any standard IEEE 802.11b/g/n Wi-Fi enabled device, enabling users to utilize any manufacturers handheld of their choice.These networks can be deployed as standalone systems, making them ideal for communication during longwall moves and in temporary work areas

POINT-TO-MULTIPOINT PoE DISTRIBUTION

StrataConnect DigitalBRIDGE™ is a point-to-multipoint Power-over-Ethernet (PoE) digital network for underground applications. It delivers both power and high speed data over a single coaxial cable to any location where digital end-point devices are desired. DigitalBRIDGE™ provides data speeds and capabilities comparable to fiber and can be used for Voice-over-IP (VoIP) communications, high-speed Wi-Fi data access, video, telemetry, tracking, tele-remoting and more. 

Power and Connectivity where you need it, when you need it.

DigitalBRIDGE™ is simple to install and maintain, and is fully recoverable. Network management can be completed by on-site personnel, without the need for specialized technicians. Utilizing off-the-shelf tools and standard procedures, personnel can cut and splice the coax cable to install or remove PoE end-point devices anywhere along the network. DigitalBRIDGE™ is an ideal solution for extending digital coverage beyond the reach of fiber, with the option to travel in multiple directions. It can also be used as a stand-alone system.
