essential to maintain its control and operation , both on site and remotely .
Additionally , the company highlighted the SD- WAN ( Software Defined Wide Area Network ) system , which represents the evolution of the intelligent enterprise network . This system optimises user navigation and operates with high levels of security to mitigate vulnerabilities , thus improving productivity in offices , branches and remote sites with simple , secure and robust connectivity . The tool includes 24 / 7 monitoring and control of critical applications , offering an exceptional experience to collaborators and clients .
One of the novelties that Entel brought to Exponor is its exclusive alliance with SpaceX , which enables connectivity in remote areas through the Starlink satellite network as exemplified by the Salares Norte example . This technology allows high data transfer rates with very low latency , opening multiple opportunities for productive applications in mining and improving workers ' stay conditions , which is crucial for talent retention and the quality of life of collaborators .
Mario Núñez , Vice President of Entel Empresas , said that the company “ has taken on the challenge of developing network services and infrastructure that guarantee operational continuity in the mining sector . Our objective is to contribute to the great challenges of the industry and the country , supporting the increase in production and the key role of Chile in the fight against climate change . In this way , we seek to contribute to reinforcing Chile ’ s global leadership in the industry and the challenge of maintaining that position to satisfy the high demand for critical minerals necessary for the transition to electromobility , such as copper and lithium .”
In addition , Entel enabled a powerful 5G network during Exponor 2024 to provide a stable connection to its clients present at the event , ensuring an advanced and efficient connectivity experience .
Hytera ’ s new intrinsically safe smartphone
Hytera Communications , a leading global provider of professional communications technologies and solutions , has recently released its intrinsically safe smart device PNC460U . This groundbreaking device , designed for hazardous environments , boasts enhanced safety , open API , intuitive Push-to-talk over Cellular ( PoC ), and rugged hardware , and it says has great potential to significantly boost team productivity in challenging settings such as mines , chemical plants , refineries , and steel mills .
For operators in industries where potentially explosive gases , dust , or chemical vapours are part of the daily landscape , the need for a communication solution that ensures both work efficiency and personnel safety is paramount . “ The PNC460U is tailored specifically to meet these needs , satisfying the intrinsically safe requirements for use in Class I , II , III ; Division 1 ; Groups C – G ; T4 and can operate in temperatures ranging from -20 ° C to + 60 ° C . It ensures reliable
Hytera ' s intrinsically safe communications smart device , the PNC460U and efficient services , even in the harshest working conditions . Functioning as a professional smartphone , the PNC460U runs on Android 12 , featuring an open API for seamless integration of customised third-party apps , addressing specific needs like access control , staff management , and physical security .”
The PNC460U features a dedicated physical PTT button , intuitive and dependable , delivering instant communication , a critical advantage in urgent situations over the app-based PTT . By leveraging the Hytera HyTalk Pro platform , the PNC460U enables seamless communication with PDT , DMR , or TETRA radios via 3G , LTE , or WLAN networks .
With an impressive IP68 rating , the PNC460U provides water resistance in freshwater up to 1.5 m for 30 minutes and it is dust-tight without requiring additional cases or protections . The device ’ s reinforced ruggedness has passed rigorous testing , including a 1.5 m drop onto a hard floor . Professionals can now focus on their work without concerns about connectivity and communication , even in the most challenging of environments .
Nerospec enhances data collection in remote underground mining
In the complex and often harsh environments of underground mining , reliable data collection is crucial for optimising operations and ensuring safety . However , one of the significant challenges faced by mining companies is maintaining consistent communication connectivity , particularly in remote sections where traditional network infrastructure is either unavailable or impractical to implement . To address this challenge , Nerospec SK has developed an innovative solution called neroMARSHAL that
leverages store-and-forward technology , allowing continuous data collection even in areas without direct network connectivity .
Underground mining machines , such as drill rigs , are often stationed in fixed locations and are equipped with a range of sensors that monitor critical parameters like location , levels , flows , RPM , speed , pressures , and temperatures to name but a few . These sensors generate valuable data that must be transmitted to the surface for analysis and decision-making . However , in remote areas with no communications infrastructure , transmitting this data in real-time is impossible . neroMARSHAL overcomes this limitation by using an onboard logger and controller from our HUB family of products such as the neroHUB , which gathers and stores the data on the machine itself .
The value of neroMARSHAL lies in its ability to utilise other mobile mining equipment within the mine as data carriers . Consider a scenario where a light-duty vehicle ( LDV ) passes by a stationary drill rig . As the LDV moves within proximity of the drill rig , it automatically collects the stored data from the rig ' s onboard system to its onboard neroHUB . The LDV continues its journey through the mine , and when it eventually comes within range of an underground Wi-Fi hotspot , it uploads the collected data to the mine ’ s network . This data can then be accessed on the surface through our web-based software dashboard , SIMAC ® ( Short Interval Monitoring And Control ), providing mine operators with the critical information they need to make timely decisions . This store-and-forward method , powered by neroMARSHAL , ensures that even in the absence of continuous network connectivity , data from remote mining machines is not lost but rather collected and transmitted effectively . It also significantly reduces the need for extensive and costly network infrastructure , making it a costeffective solution for mines operating in challenging environments .
To further enhance underground connectivity , Nerospec SK also offers specialist network products designed specifically for the mining environment , such as neroPOYNTs and neroLANTERNs . These solutions provide robust Wi-Fi connectivity , ensuring that data collected by mobile equipment can be swiftly uploaded to the mine ’ s network as soon as a connection is available .
Nerospec says its innovative approach to data collection and transmission " reflects our commitment to providing mining companies with the tools they need to operate efficiently and safely , even in the most remote and difficult-toaccess locations . With neroMARSHAL , mines can maintain continuous monitoring and control of their operations , ensuring that vital data is always available when and where it is needed ."
