NETWORKS & CONNECTIVITY reseller/integrator community to provide some installation and postinstallation support. Moccia adds: "Another big unique aspect of Redline is our scalability offering to mining, being able to provide solutions from juniors right up to top tier companies. Our EPC licensing starts at just 25 users compared to the 100,000 users minimum from some the global telecomms companies. Our EPC is also completely hardware agnostic and is based on user demand. So, you can connect 25 users on a private LTE network. For larger LTE networks with 25,000, 50,000 or more users, we can centralise it on a CPU or decentralise across multiple CPUs based on what the customer wants. It can be hosted onsite or in the Cloud. Our solutions are also cost effectively designed for scale, designed for the industrial not the carrier sector." Looking at its mining private LTE market, Redline now has six major installations, for now all in North America, three underground and three surface. Several of them are also running autonomous equipment pilots. Above ground it is through collaborations as it isn't a mobile network operator with access to spectrum so for these projects it works with spectrum holders. Underground it is a different story as in North America you don’t need to work with the regulators for spectrum; you can choose to use whatever spectrum suits your needs. Moccia comments: "The driver for existing mines wanting private LTE is the limitation of their existing WiFi networks including mesh but the LTE is more of a complementary expansion rather than a replacement. For many applications WiFi remains more than enough, but for mobility, autonomy and density requirements, but for real time connectivity, push to talk comms etc, LTE works much better. But WiFi and LTE coexist." One of the surface projects is with Baffinland, the Canadian iron ore mining company that operates the Mary River mining operation in the northern part of Baffin Island, well above the Arctic Circle. They are a long term customer - several years ago Redline started working with them as the mine was being challenged with propagation of RF signals and their high latency solution was unable to support real-time control and monitoring especially for the conveyor belt which ran between the mobile ship loader systems and the feeder subsystems. After using other digital broadband wireless systems, they deployed a Redline virtual fibre solution with the ability to deliver high quality point-to-multipoint (PMP) communication systems. This has now evolved into them installing a Redline full private LTE network which they are using for some autonomy trials. Elsewhere, Redline has also installed other private LTE networks at surface mines in Utah and one in Nevada. Also in Canada, Redline is working with a number of underground mining entities on rolling out private LTE networks. Redline is confident that its technologies' simplicity is a significant differentiator – it doesn’t have the complexity that comes with a carrier architecture to the point where workers that have operated LAN and WiFi systems can be easily trained to build, operate and maintain the Redline private LTE. To maintain some competitor LTE networks would have far exceeded the capabilities of their people without lengthy and advanced training. Huawei builds LTE/5G influence in Latin America Hudbay, the Canadian mining company with more than 90 years in the American continent, and a presence in Peru since 2011 with the Mining Constancia Unit (with the new mine operational from 2014), is directing its efforts towards the digitisation and modernisation of its operations. For this reason, in Peru it has been implementing a LTE digital private network, in order to have a unified communications platform for voice and data that will allow it to interconnect the different information systems as part of its Digital Mining plan. This includes the Hexagon IDS GeoRadar slope stability monitoring system shown in the above image. According to the network supplier, China’s Huawei, Constancia, where 86,000 t/d of copper ore in mined and among the lowest cost open-pit sulphide copper mines in South America, is the fourth mining company in the Providing full service mining solutions and innovation around the world since 1962.
