Having worked in the field of mining vehicle communications for so many years, the most frequent question I receive is this:

What kind of gateway should we equip the trucks on our mine with?

This question seems simple, but to give a reliable answer, we need to break down and analyze the actual working conditions of the mine in detail. Today, we’ll discuss the selection of mining card gateways from a technical support perspective.

 

Just how challenging are communication equipment in a mining environment?

Many customers say during their first consultation, “It’s just installing a router, as long as it can connect to the internet.” Every time I hear this, I have to carefully explain the special nature of the mine.

The geographical area is vast. Open-pit mines often cover tens of square kilometers, with trucks traveling from the bottom of the pit to the spoil heap, where the elevation difference can exceed two or three hundred meters. Signal attenuation is severe in such terrain, causing ordinary 4G devices to frequently drop connections and experience high latency. Underground mines are even worse, with winding tunnels, severe electromagnetic interference, and numerous communication dead zones.

The vibrations are intense. Mining trucks aren’t like cars on the road; they’re wide-body vehicles carrying tens or even hundreds of tons. On unpaved roads, the bumps and jolting can take more than three months for a typical consumer-grade device. Loose interfaces, detached circuit boards, broken antennas—I’ve seen far too many of these.

Extreme temperature variations . The temperature difference between day and night in the mining area is large. In summer, the temperature in the cab can reach 60 or 70 degrees Celsius, while in winter, temperatures of minus 30 or 40 degrees Celsius are common in northern mining areas. Such extreme temperatures pose a real challenge to electronic components.

Dust corrosion is severe. Coal mines, iron mines, and copper mines each have their own “specialties,” and if the equipment’s protection level is insufficient, it will soon become covered in rust.

Putting all these factors together, you’ll understand why you can’t just pick any mining card gateway.

Mineral processing card gateway, these are the key performance indicators.

Based on the technical support cases I’ve handled over the years, I’ve compiled a list of the core metrics that mining card gateways must meet:

① Communication stability is paramount

Autonomous driving, remote control, and dispatch systems—which of these doesn’t rely on a stable network? A communication interruption can range from impacting efficiency to causing safety incidents. Gateways must have multi-link redundancy, automatically switching over if a single channel fails.

② The bandwidth must be sufficient.

Nowadays, mining trucks are equipped with more and more devices: high-definition cameras, lidar, millimeter-wave radar… 4K video transmission and point cloud data upload are impossible without sufficient bandwidth.

③ Rich and reliable interfaces

The camera uses Ethernet, the ECU uses CAN bus, and various sensors, alarms… the gateway must be compatible with different protocols, and the interface must be automotive-grade, shockproof and resistant to loosening.

④ Time synchronization accuracy

This is the most easily overlooked point. Multi-sensor fusion, V2X collaboration, and platooning have extremely stringent requirements for clock synchronization; even millisecond-level errors can cause data fusion to fail.

⑤ Remote management capability

The equipment in the mining area is scattered, making it impossible to send someone to maintain each vehicle on-site. The gateway must support remote configuration, diagnostics, and upgrades, and ideally, it should also be able to remotely wake up.

⑥ Power consumption control

After the mining truck is turned off, the onboard equipment needs to remain in low-power standby mode to respond to wake-up calls. Excessive power consumption will accelerate battery drain and affect the vehicle’s normal starting.

Starlink SV910: A Dual 5G Vehicle Gateway Designed for Heavy-Duty Vehicles

Having discussed the requirements, let’s talk about a product we use most frequently in our mining card projects—the SV910 dual 5G vehicle gateway. It’s not that it’s perfect, but considering its overall reliability and cost-effectiveness, it’s indeed very suitable for mining scenarios.

The SV910 uses a quad-core 64-bit Cortex-A55 processor, providing ample computing power to handle computational tasks while maintaining good energy efficiency. This is particularly useful for customers who need to run lightweight algorithms on their gateways.

Dual 5G architecture solves signal coverage problem

The core design feature of the SV910 is its dual 5G modules—two 5G networks operating simultaneously, enabling true multi-network aggregation. In environments with unstable signals, the advantages of dual links are particularly evident.

Bandwidth aggregation: With two 5G channels transmitting data simultaneously, the theoretical bandwidth is doubled, making it easy to transmit high-definition video streams in real time.

Redundancy and backup: If one signal weakens or is interrupted, the other automatically takes over, ensuring uninterrupted service. Seamless switching is crucial for security-sensitive applications.

Load balancing: Critical business processes use the main link, while general data uses the backup link, with bandwidth allocated reasonably to avoid contention.

Real-world example: A customer’s mining area had a section of road at the intersection of two base station coverage areas, causing frequent disconnections and reconnections for a single 5G device. After replacing the 5G module with the SV910, the two modules were locked to different base stations, completely resolving the issue.

PTP/GPTP time synchronization, the foundation of sensor fusion

The SV910 supports TSN technology and is compatible with PTP (IEEE 1588) and GPTP (IEEE 802.1AS) time synchronization protocols. It can achieve clock synchronization accuracy at the microsecond or even sub-microsecond level, with measured synchronization error controlled within 50 microseconds.

For mining trucks equipped with multi-sensor fusion, the accuracy of time synchronization directly determines the availability of sensing data—data generated by cameras, radar, and IMUs must be precisely aligned with timestamps to correctly calculate obstacle positions and speeds. Similarly, V2X vehicle-to-vehicle communication and vehicle-to-infrastructure cooperation rely on a unified time base; excessive clock drift can lead to communication collisions and outdated information.

Interface lineup covering the vast majority of wiring needs for mining cards

6-channel automotive Ethernet (T1+TX): T1 is designed specifically for automotive environments, with thinner and lighter single-pair wiring harnesses and stronger anti-interference capabilities; TX facilitates connection to standard Ethernet devices.

2-channel M12 industrial Ethernet: High protection standard, spiral locking design, dustproof, waterproof and shockproof, much more reliable than ordinary RJ45 in harsh mining environments .

3-channel CAN interface: The engine ECU, transmission controller and braking system of mining trucks mostly use CAN bus communication, and 3 channels of CAN are sufficient to cover all subsystems of the vehicle.

2-channel DI + 2-channel relay output: can be connected to various sensors and actuators, such as emergency stop buttons as DI inputs, relays to control audible and visual alarms, and realize simple local interlocking logic.

This interface combination can basically cover the access needs of most devices on mining cards, eliminating the need for a bunch of external converters and expansion boxes.

Remote /local wake-up, low power consumption, reduced operation and maintenance costs

Remote/local wake-up technology is the third major breakthrough of the SV910. As fleet size expands, energy consumption and maintenance costs rise accordingly. Starlink’s SV910, through its first-ever remote or local wake-up function, supports triggering low-power modes via either TCP protocol or CAN bus, enabling remote start/stop and job scheduling management, remote diagnostics, and remote upgrades. This significantly improves fleet operating efficiency and reduces energy costs, promoting a green and low-carbon approach.

V2X capabilities support collaborative operations in mining areas.

The SV910 has a built-in V2X module, supports the C-V2X standard, and can communicate directly with other vehicles and roadside units equipped with V2X devices. Typical V2X applications in mining scenarios include:

Formation driving coordination: Multiple mining trucks form a convoy, with the lead truck controlled by a driver and the following trucks automatically following. The trucks exchange position, speed, and intention information in real time via V2X to maintain a safe distance.

Collision avoidance at intersections: Road intersections in mining areas are accident-prone areas. By broadcasting the location via V2X, nearby vehicles can detect the presence of the other vehicle in advance, triggering a warning or actively slowing down.

Roadside equipment linkage: Traffic lights, speed limit signs, electronic fences and other roadside facilities push information to vehicles via V2X, and vehicles can also report their status, realizing two-way interaction.

The SV910’s dual 5G and V2X are two independent communication channels: 5G is responsible for long-distance communication between the vehicle and the cloud, while V2X is responsible for short-distance direct communication between the vehicle and its surroundings. The two complement each other and work together to build a complete vehicle-to-everything (V2X) communication system.

These selection tips are based on mistakes we’ve made in our projects.

Pay close attention to antenna deployment. Even the best gateway is useless if the antennas are poorly installed. Mining trucks are mostly made of metal, so antennas must be installed on the roof or other open locations to avoid obstruction. 5G antennas and V2X antennas are best installed separately to reduce mutual interference.

Protect your interfaces. While the device itself has automotive-grade protection, prolonged exposure to dust and moisture will still accelerate interface aging. It is recommended to install protective covers or sealed enclosures, and to waterproof the connectors.

Plan your network architecture in advance. Determine which data will use 5G, which will use V2X, and which will be processed locally. A reasonable data offloading strategy can significantly improve overall system performance.

Reserve upgrade space. Intelligent mining is a continuous evolutionary process; current needs do not represent future needs. Choose a gateway with abundant interfaces and sufficient computing power to facilitate future expansion.
