MINING NETWORKS & CONNECTIVITY Paul Moore spoke to Stephane Daeuble, Head of Enterprise Solutions Marketing at Nokia, to get a better understanding of the significance of 5G SA for the mining and METS industry when compared to other 5G solutions as well as LTE Q Is 5G SA essentially a scaled down, trial or smaller version of a full 5G network or just this represent the first full rollout of 5G for industry from Nokia? A 5G based on 3GPP R15 came in two architectural flavours. The first called 5G non-standalone (NSA), came earlier in the standard and was designed for CSPs to quickly adopt 5G, by relying on the LTE architecture (and LTE for uplink) and just adding 5G radio. The second called 5G standalone (SA), is what some people call the “real 5G” with a full 5G core architecture, and that will form the baseline for future 5G innovations linked to industrial needs coming in later releases (R16, 17, etc). 5G SA is best for enterprise as they do not have to deploy LTE and 5G, find spectrum for both, the uplink channel is really on 5G, etc…and it is the architecture that they will need for the future to benefit from 5G innovation. its use cases). The exception is the manufacturing space, particularly automotive manufacturing, which has quite a few existing and new use cases that need 5G. Since the majority of industrial segment use cases work fine on 4.9G (mining is an example), there is a very healthy ecosystem of devices/assets/machines that support LTE (eg Komatsu), and available spectrum for private 4.9G, etc. We believe starting with private 4.9G will continue to make sense until we are further down the standardisation timeline for 5G, and a healthy industrial ecosystem exists. The last important point is that 4.9G/5G are part of the same family of technologies. Private 4.9G networks sold today by Nokia are 5G ready, hence can easily be upgrade to 5G when needed and the time is right (ecosystem, standards, etc). Last point to consider, and to explain why Nokia is announcing commercial 5G SA private wireless solution, is that there are also a few markets, that have 5G vertical spectrum and not 4.9G spectrum. As a result, it makes sense for them to start early. And finally many ecosystem players want to start to test/validate 5G technology early to embed it into their future solutions to build a healthy ecosystem of 5G connected assets. Q Because 5G has some advantages over LTE/4.9G, is it now more logical for mines wanting to invest in new networks to bypass LTE and go straight to 5G? A Investment timeline is a decision that has many factors. 5G is surely the technology of the future, but it is also still early days: 5G standards are still a work in process– the full industrial features set will come with R18 (standardisation planned for 2023) and some IoT capabilities like LTE- M/NB-IoT for low power, high battery life sensors will need LTE/4.9G until R18. Because of this, the 5G ecosystem is still in development; meaning you will be only able currently to implement a few use cases. With Nokia 5G SA, it’s a big step forward in stimulating the ecosystem to build use cases, as it provides a commercial platform upon which to develop them. Then, you need to consider your operation and use cases, and whether they need 5G or not. Today the vast majority of industrial segment use cases are totally fine with LTE/4.9G (as that networking supports in excess of 85% of Q Is it fair to say that this is not the first 5G offering available to mining companies – as an example Huawei has announced the installation of a number of 5G networks in both surface and underground mines? A Nokia has already been shipping private wireless systems for quite a while based on 5G, but as per explanation above it was based on 5G NSA and not 5G SA. This time, we are talking about 5G SA – and we are the first with commercial industrial-grade private wireless solutions. Nokia has more than 180 private wireless enterprise customers worldwide, of which more than 30 engagements are 5G. Q In a recent webinar Komatsu and Nokia mentioned that 5G will be tested at Komatsu’s Arizona Proving Ground, will this also be a 5G SA network? A The customer is indeed looking at 5G, but details cannot be disclosed at this moment. The 5G discussion with mining customers and partners is oriented to be SA in place. complement to LTE, Fluidmesh offers a solid private network able to deliver Distribution and Access layers to trailers and vehicles in open pit mines. Thanks to its MPLS-based protocol Cisco can now merge the benefits of high-throughput and low-latency, enabling new mission-critical applications such as AHS, ADS, tele-remote, FMS dispatch and control at a new level, and offering a full end-to-end fixed and nomadic network to their clients in this and many other industries.” Komatsu and Nokia talk networks and AHS A recent webinar from Nokia and Komatsu Mining entitled Making Autonomous Haulage Systems a Reality covered how industrial-grade private LTE wireless networks are powering mining innovation, specifically looking at AHS, while including an update from Komatsu on its AHS progress and its preference for LTE over WiFi backed up with specific cases, as well as discussing in some detail how the two companies have been and will be working together. Jaime Laguna Ramirez, Nokia Global Practice Segment Leader for Oil & Gas and Mining said that asset intensive industries like mining are pushing the convergence of IT and OT as key elements like intelligent analytics, AI and machine learning systems are demanding high bandwith, low latency and massive connectivity. He added that Industry 4.0 is making mining safer, more efficient and more productive. Efficiency is increasing wth process automation, with increased agility to meet fast changing requirements. It also allows for better decision making via intelligent insights while increasing worker safety and productivity. Lastly there is undoubtedly a sustainability factor as the greater efficiency helps lower environmental impact. All this while maintaining asset heavy industries “must have” needs of continuous operations with multiple redundancies & mission critical performance, efficiency/safety relying on coordination between multiple physical assets at work sites and in the field and security, while having the flexibility to react to change. Nokia is a mission critical telecoms companies that has been able to work with miners to fully understand how connectivity fits in with all of these needs. Nokia also quickly realised the importance of interoperability and working directly with key industry technology suppliers like Komatsu. Digitalisation and automation are now filtering through the whole mining process from data enabled exploration to the construction supply chain, integrated drill and blast with AHS fleets, fully integrated mine to plant processing, product delivery logistics and end to end asset management, to the point where Bell Labs Consulting has estimated that automation in total is now having an average 17.2% positive effect on mining productivity, with AHS fleets alone accounting for 5.5% of this. Laguna Ramirez admitted that wired networks will continue to play their part in certain areas, but argues that adapted WiFi systems that have met needs until now will not be able to meet future needs in reliability, security and performance. In industrial wireless terms, Nokia says the choice can make or break a mine’s journey to digital transformation. P2MP networks are one option but Nokia argues that they have disadvantages like low scalability, non-Cloud management/operation, relatively low availability (95.5%), resiliency and reliability and using a proprietary vendor lock in 28 International Mining | SEPTEMBER 2020
