Industry 4.0 encompasses interconnected cyber-physical systems, particularly in the mining sector, which often operates in remote and rugged environments characterized by complex terrain, limited AC power, and high poles. Reliable communication technology is essential for ensuring safety and operational efficiency in these challenging conditions. QLink Super Wi-Fi™ solutions provide robust wireless connectivity that facilitates real-time data transfer, remote monitoring, and communication between equipment and personnel. Our technology empowers miners to enhance safety protocols, optimize resource management, reduce costs, and maintain seamless operations, ultimately leading to improved outcomes.
Wi-Fi facilitates wireless communication between vehicles(dump trucks, drilling machine, etc.) and Operations Center, enhancing operational efficiency in:
Wi-Fi connects cameras to the Control Room for:
Wi-Fi supports diverse IoT devices and sensors, allowing for seamless connectivity and data transmission to central system. This capability enables:
Wi-Fi facilitates communication among personnel via the wireless network, thereby improving coordination and overall workplace efficiency.
Mines can be 10 km or more in radius and feature multiple tunnels that measure in the 10s and even 100s of kilometers in length. The physical topography of the environment is also very challenging: not only do networks have to cover large areas, but very uneven ones, both above and below ground
Usually, mines are located in wide-spread areas with limited high points for WiFi installation. Typical available points for WiFi antenna installation are at the top of light tower, removable pole with solar energy. Fiber/Wired backhaul connection is not available for the site.
AI and IoT devices offer substantial benefits, but they require seamless coverage as they operate and coordinate heavy machinery in an unpredictable and often dangerous environment. Redundancy is critical, as is ongoing planning and testing to ensure connectivity remains seamless.
Mission-critical operations ( e.g. vehicles ) demand robust wireless connectivity and seamless roaming between access point coverage zones, necessitating effective roaming solutions.
There is high explosive risk for underground mining environment, anti-explosion is important part of WiFi implementation. Crushed stone and dust can easily cause damage to equipment.
8×8 MIMO array: Take advantage of multi-path signals to achieve high diversity gain in NLOS environment.
Patented smart antenna algorithm: Analyze all the Rx signal paths to achieve a higher uplink signal level, hence improving uplink performance for those low-powered devices.
1 x A8-Ein(ac) can provide coverage for a distance of 1.7 km in LOS environment
1 x A8n(ac) can provide large area coverage with beamwidth 70 to 360º
The QLink AirFi throughput optimization algorithm implemented at the Wi-Fi layer, increasing its average throughput capacity by a factor of 2 and more
Fast Handover – Enhanced active background scanning and roaming threshold enable QLink CPE to have a handover time of 80 – 100 ms
Smart Roaming – QLink AP proactively monitors client connection status and uses standard (802.11k/v/r) or non-standard mechanisms (client RSSI/PER) for facilitating client roaming to mitigate the effects of poor handover decisions made by clients alone
Zero Packet Loss – The QLink APs involved in roaming communicates with each other to enable intelligent packet buffering and forwarding, reducing packet loss to zero
With four sector antennas, A8n(ac) can provide flexible coverage for different environment by using different down tilt settings.
