Principal Technical Architect, GSMA
Stephen Doyle is Principal Technical Architect for GSMA covering topics in the IoT related to Big Data, Machine Learning/ AI and distributed ledgers. A graduate in Computer Systems Engineering from the University of Warwick in the UK he has worked for a range of IT and Telecoms companies comprising equipment manufacturers, mobile operators, and application/ service developers. Since 1994 Stephen has worked in the Mobile Industry mainly in the areas of applications and services and is particularly experienced in the definition, development and usage of web/mobile APIs. For the GSMA he has been leading system architecture and implementations regarding use of Big Data and Machine Learning related to IoT, also the application of distributed ledgers to the IOT and other areas of mobile networks.
Aruna Srinivasan, GSMA: The other (82%) of connections would be based on wired LANs, Wi-Fi, NFC (near-field communications), Bluetooth, and other unlicensed wireless technologies.
Chris Allen, Vodafone: Virtual MPN (5G Network Slicing) is a logical share, using the same physical resources as the public network. Business customers are allocated their own “virtual slice” on the public network that they (and only they) are able to use.
Chris White, Ford: We would typically hard wire machines like this, but this takes time.
We are always looking at ways to reduce launch times and also give ourselves more time to work on the accuracy of the data before we launch. We will reconfigure lines frequently and aim to do so within a shift, so re-cabling data is not an option. Finally, whilst the welding machines are always likely to be static, many of our facilities are not and that is a growing trend. The welding machines are a proof of concept for more portable equipment and processes.
Steve Doyle, GSMA: In the future factory the expectation is that there will be regular reconfiguration of even physical lines, moves are therefore more convenient if the connectivity uses 5G rather than wired networks. Wired networks also carry with them certain risks or limitations e.g. the risk that a cable is pulled from either end, or cut, or that maintenance on a switch/ router disconnects the equipment, etc. Also if surrounding physical equipment is changed the wiring might need to be re-routed even for a fixed location machine. In any of these cases licensed cellular provides advantages.
Chris Allen, Vodafone: ROI can vary significantly from customer to customer, and really depends on use cases. It can be driven by a number of different factors: increased productivity (automation), quality (fewer defects), worker safety (fewer accidents), reduced energy consumption, and less downtime (predictive maintenance). We typically consult with the customer upfront and conduct a Business Impact Assessment with them to quantify the value on a case-by-case basis.
Chris White, Ford: For installation in an existing facility (replacing an existing network), we would expect payback in a year. As our project progresses, I expect to find opportunities for savings with 5G, but perhaps not to this extent. That’s why we think there is a better business case on greenfield or brownfield sites, with new programs. In this situation, we hope to get costs closer to hardwired networks and offset any delta with the subsequent costs of reconfiguration and later additions.
Chris Allen, Vodafone: The solution deployed at Ford is a Dedicated MPN using 5G network equipment supplied by Ericsson (“5G Radio Dot” indoor cells).
Chris White, Ford: This is a dedicated mobile private network.
Steve Doyle, GSMA: Security can be argued either way. As an example consider private Wi-Fi networks, although in the best case these can be highly secured with strong passwords, over the air encryption, device identification & authentication, and well maintained access points from reputable suppliers there are often vulnerabilities introduced through poor equipment selection, installation and maintenance. The same can be true of a poorly installed or maintained standalone private network and this is why GSMA recommends Mobile Network Operators as a supplier of any private/ dedicated network option since they have a strong track record in keeping mobile networks secure. Network slicing does offer comprehensive partitioning of customer traffic from other network users, and commercial enterprises should find this meets their security and privacy needs with the advantage of ongoing monitoring, patching and maintenance.
Chris White, Ford: This is a specific part of our project. Our current facility is a pilot line making trial and prototype parts, but much more needs to be done before we can be confident of controlling safety and productivity risks in a ‘real’ factory.
Steve Doyle, GSMA: The Ford factory deployment is an excellent example. Various other deployments are being made by DT, Orange, Telefonica. For details please see the Private Networks paper recently published by the GSMA.
Stephane Gervais, LACROIX Group: We, as a user, are responsible and in charge of data encryption.
Steve Doyle, GSMA: The encryption on the mobile network (including over the air) can usually be relied on to provide secure communications without requiring application level encryption. Mobile network operators often offer solutions to protect enterprise data further e.g. VPN connection to the enterprise and enterprise specific APNs (Access Point Names). Network slicing and edge computing take these concepts further providing further advantages in aspects such as latency because encryption is not needed on top of communications packets, also device complexity and cost can be reduced.
Stephane Gervais, LACROIX Group: I don’t have the figures yet. We are first experimenting with 5G to understand the best use cases, then cost comparisons will be done based on the validated use cases.
Steve Doyle, GSMA: Although GSMA has no specific models that we’re aware of there is likely to be an inflection point where Wi-Fi is attractive for limited capacity/ coverage use but very quickly hits the point where it cannot provide the required capacity, coverage and latency requirements for Industry 4.0. Basic equipment cost is therefore not the only consideration. TCO must also consider reliability and availability and flexibility which will be key advantages of licensed cellular compared with other options.
Stephane Gervais, LACROIX Group: Data and the data cloud are managed by LACROIX GROUP. We’re getting additional data from other sources through LAN, WiFi, etc.
Chris Allen, Vodafone: Yes, typically via some kind of mobile gateway/router device today. Over time we expect the machine manufacturers to integrate 5G capability to their newer machines so they can communicate “natively” with a 5G network, but existing legacy machines can also be retrofitted with 5G modules too.
Steve Doyle, GSMA: We also expect there will be a variety of options here including modules that can be retrofitted to industrial machines, converter boxes that can for example connect SCADA over 5G, newer industrial machines which will integrate 5G, and router devices which can perform Ethernet or Wi-Fi to 5G connectivity. Edge computing is not strictly necessary, but we expect this will often be used in Industry 4.0.
Stephane Gervais, LACROIX Group: private network seems an interesting option avoiding us to acquire equipment
Steve Doyle, GSMA: From the GSMA side we think that most manufacturers will outsource to carriers or equipment vendors rather than build in-house teams. There are exceptions of course e.g. Airbus, who have particular business drivers for such in-house teams, but we think mobile operators are going to be the first point of call for most manufacturing organisations not least because of existing relationships, spectrum, public network access and availability of the full range of skills needed to design, install and operate the private network.
Stephane Gervais, LACROIX Group: On the manufacturing side, latency is key and our test values shows that 5G latency is low and predictable. One issue with 4G, beyond high latency, is that latency is not consistent.
Steve Doyle, GSMA: Some of the major latency improvements from 5G are dependent on Release 16 and Release 17 so this is currently early days for ultra-low latency. However, realistically this is coming in 2021. As La Croix Group indicate a key advantage of 5G is the low and predictable latency, and this is a significant advantage over Wi-Fi and other unlicensed radio technologies.
Ronan le Bras, Orange: Orange Business Service is a system integrator.
Stephane Gervais, LACROIX Group: From LACROIX Groups’ side, yes. At this stage we need to focus on validating use cases and make technical comparisons with other types of technology.
Steve Doyle, GSMA: 5G has the advantage that spectrum is being made available over three distinct regions for coverage (under 1 GHz), balanced capacity/coverage (>1 GHz and to 6 GHz) and ultra- high capacity in the mmWave bands. The radio performance is better than 4G (which is also better than earlier generations) so this certainly helps with the deep indoor use cases – just as 4G LTE-M and NB-IoT deliver across existing 4G LTE networks. In reality we expect 5G to deliver advantages across many different deployments and use cases.
Stephane Gervais, LACROIX Group: We do encryption end to end and will use PKI after first testing.
Ronan le Bras, Orange: For that project, a similar solution based on scenario 3 would be the preferred one to answer the needs expressed by LACROIX Group in order to keep data on site.
Steve Doyle, GSMA: This is a good point, and, will be an additional complexity that customers will not be used to dealing with. Mobile operators are often involved in compliance activities, though some of these are dealt with through agencies such as the US FCC. We would think that MODEM manufacturers would be required to ensure device compliance for dedicated spectrum, but this challenge should not be underestimated considering the potential for different combinations of devices and private networks and available spectrum.
Chris Allen, Vodafone: MPN use cases for ports tend to be logistics/automation related – e.g. remote crane operations, asset tracking, monitoring of vehicle movements – but can also be for worker safety (geo-fencing, collision avoidance, fall detection), security (CCTV analytics, drone detection) and productivity (electronic job scheduling, push-to-talk/push-to-video solutions). In summary, the use cases are many and varied.
Lov Kher, Verizon: Verizon has a Private 5G solution available in Europe and Private 4G LTE/5G is under trial with several customers in the US.
Steve Doyle, GSMA: Yes, private network solutions are commercially available from both mobile operators and a number of equipment vendors. This includes 4G as well as 5G.
Steve Doyle, GSMA: In theory the support and maintenance responsibilities could be wholly outsourced by a manufacturer to their supplier e.g. a mobile network operator. Some operators will be able to do this, others may pick up the level 3, or level 2 and 3 responsibilities. Where a manufacturer has an on-site technical team it’s very likely this will continue to cover level 1 responsibilities with the mobile network operator providing maintenance as well as level 2/3 support.
NB: Tier 1 support – Basic helpdesk resolution and service desk delivery. Tier 2 support – In-depth technical support. Tier 3 – Expert product and service support.
Lov Kher, Verizon: Verizon is already working with several companies in their factories in the US running computer vision and AR along with Private 5G/MEC for different use cases such as identification of foreign material, product quality, and training among others.
