Miners have a wide variety of tag and tracking technologies to choose from, each with its own requirements and benefits. Here’s a quick overview of tags used in underground mining today, their related radio network requirements, some pros and cons of each type of tag. 1. Radio Frequency Identification (RFID) Tags are small radio transponders that transmit a unique identifying number to a reader when triggered by an electromagnetic pulse. They require a network of readers and antennas strategically placed throughout the mine. + • Reliable tracking and access control • Passive tags are cost-effective - • Limited range and susceptible to interference • One-way communication provides limited insight • Requires a dense network of readers for effective coverage 2. Wi-Fi Tags use existing Wi-Fi networks and positioning algorithms to localize personnel and mobile assets. A high volume of Wi-Fi access points is required for detailed positioning. + • Utilizes existing Wi-Fi infrastructure • High data transfer rates and accuracy in line-of-sight conditions • Ability to integrate with other systems - • Requires a robust Wi-Fi network • High power consumption leads to shorter battery life • Lack of standardization across Wi-Fi solution vendors 3. Ultra-Wideband (UWB) Tags use high-frequency radio technology to transmit unique identifiers in short pulses, enabling precise location tracking. They need a mobile or Wi-Fi network and a dense network of anchor points. + • Highly accurate real-time location tracking • Performs well in challenging underground environments • Provides centimeter-level precision for personnel and asset monitoring - • Requires more complex and costly infrastructure • Higher power consumption than other tag technologies • Limited adoption and availability compared to RFID and BLE 4. Virtual Tag Mobile Apps use standard smartphone operating systems to provide two-way communication and real-time situational awareness without specialized hardware. Smartphones can use Wi-Fi, cellular, and Bluetooth radio technologies, making integration seamless. + • Easily installed on widely available consumer devices • Eliminates the need for physical tags or beacons • Provides two-way communication and more value for workers - • The cost of supplying workers with phones may be relatively expensive • Users must keep their devices charged and with them at all times • Cyber security vigilance is required 5. Bluetooth® Low Energy (BLE) beacons are not tags themselves, but separate units installed in places where the network is poor, or where you need to improve location accuracy in the mine. BLE beacons use Wi-Fi or cellular to communicate readings. + • Leverages ubiquitous Bluetooth technology • Supports real-time location tracking and proximity monitoring • Battery-powered BLE tags will last 3-4 years - • Can require a more extensive network of BLE beacons • Obstacles and interference may affect performance #Epiroc #Safety #SituationalAwareness
