High-Speed Mining Network by G.hn over Coax or Power-Line


High-Speed Underground Mining Wired Communication Solution

Xingtera provides solutions to re-use existing underground mining cables (coaxial cables, twisted-pair wires, DC power-lines, etc) in order to enable reliable high-speed multi-node IP networks, for data, voice, video, and Ethernet data traffic throughout the whole mining site. Wired mining connectivity has been proved to offer better stability, redundancy, and flexibility. 

Traditional Mining Communication Solutions

With the ever-increasing demand for IP networks in all mining sites, traditional communication or IoT solutions are experiencing all sorts of issues.

  • Fiber optics provide the longest distance and the highest data rate, yet they are very fragile thus not flexible enough for a lot of underground situations;
  • Ethernet cables are most common, however they can usually only achieve 100 meters of point-to-point communication. For large scale data networks, it’s always a challenge to install enough Ethernet cables as well as industrial Ethernet switches. Furthermore, the cost could get very high when the scale picks up;
  • Wireless solutions are the most convenient of all. Unfortunately, in order to implement reliable wireless coverage, multiple access points (AP) or base stations must be established first, with a wired backhaul network to connect all points with the main router or gateway above ground. Therefore the infrastructure cost is really high and almost unbearable for small and medium-sized mines.

High-Speed Wired Communication Mining Networks 

Because of all these challenged faced by traditional networking solutions, Xingtera’s wired communication solution provides a helpful alternative for reliable underground mining multi-node networking.

Based on Xingtera’s PLC or G.hn technologies, up to 1,000 nodes can be connected together using the same coax, twisted-pair, or DC power cables. The large number of concurrently online nodes helps to enable modern IoT applications in the mining industry. The maximum distance between any two nodes can be as high as 2KM (coax) or 800M (twisted-pair). The aggregate data rate can be as high as 1.7Gbps depending on multiple conditions. Furthermore, it is possible to use the same copper wire to provide DC power and IP data traffic at the same time. 

Xingtera provides multiple choices of PLC or G.hn high-speed communication modules, for easy integration to mining devices, and faster time to market. Depending on the actual requirements of data rate, the number of nodes, latency, etc, we will recommend you with the best fit for your application. 

Xingtera’s underground mining wired communication solutions have already been deployed in many mines globally. If current modules or solutions cannot fit the need 100%, Xingtera also offers customization service including software, hardware, and system-level development to better address each customer’s unique mining connectivity and IoT requirements.
