“Demand [for private 5G] will rise… however it’s going to take years,” feedback Daniel Mai, director of commercial wi-fi at Siemens, in dialog final month at Hannover Messe – selecting up from the place we left off right here (see earlier put up: Non-public 5G and generative AI – ‘the place Business 4.0 will get actual’, says Siemens).
There’s that acquainted reserve, once more. What does Siemens make of all of the hype within the 5G market? (The query needs to be whether or not the AI hype is any completely different; however it has already mentioned on stage that it’s completely different, and a bunch of different questions movement anyway.) How massive does Siemens assume the market really is? Does it regard this seminal forecast from Nokia about 10 million factories as correct, and helpful; or is the agency most focused on Launch 18-level URLLC and TSN for high-fidelity manufacturing unit automation? And is {that a} area of interest market, really?
“I can’t inform the longer term,” responds Mai. “However it’s an enabler; that’s how we implement it and that’s how we pitch it.” He references current work with Volkswagen subsidiary Audi, taking the agency’s newly launched digital PLC product, to cut back shop-floor {hardware} and streamline manufacturing at a manufacturing unit in Ingolstadt, in Germany; it has a comparable venture with Ford within the US. (He says one thing about parallel work with Deloitte, as properly, which has emerged as a major integrator for its non-public 5G system.) The purpose is simply that factories are being twinned and managed in software program, and higher networks are wanted for the duty.
Mai explains: “Virtualization of commercial {hardware} is going on, however it wants connectivity. Industrial 5G, and doubtless 6G sooner or later, will probably be an enormous a part of this. However these transitions take time. Our recommendation to clients is to begin now, to be prepared – as a result of beginning in 5 years may be too late.” His 2025/26 timeline (see earlier put up), for personal 5G to correctly pick-up in Business 4.0, is in line with what Siemens has all the time mentioned, and makes the post-hype deflation within the telecoms market look foolish. Actually, 5G-ACIA sounded just a little deflated on stage right here, at Hannover Messe.
So what does Siemens, which paints itself as a realist in a gallery of fantasists, make of the temper in the remainder of the market? Presumably, the hype is no-bother and the delay is no-sweat – as a result of it exhibits its timing is correct? “The deflation, in comparison with the hype, is appropriate. However if you happen to see what generative AI can do, then you will note the way it picks up,” says Mai, once more referencing the looming AI cardio exercise for industrial information methods. He’s saving-up the examples, however Siemens has already talked-up its Teamcenter platform because the heart-pump within the new Business 40 anatomy.
The legs and arms simply have to be related correctly, the message goes. So, let’s persist with 5G for the second: what number of methods has Siemens bought? “It’s nonetheless early-days, and our clients now have official-product, and never simply take a look at {hardware}; and we have now a pipeline of initiatives. However I don’t wish to give numbers,” responds Mai. As an apart, on prompting, he suggests the official licence-count from regulator BNetzA in Germany (370 non-public 5G permits have been granted, mentioned 5G-ACIA on stage in Hanover) is deceptive on the grounds they cowl enterprises, not networks.
“I doubt that quantity,” he says. “I imply, Siemens is counted as one, and I do know very properly that Siemens has deployed a whole lot of 5G networks.” It has deployed much more industrial wi-fi LAN (Wi-Fi) methods in factories world wide. Its view on how industrialised variations of those networking applied sciences converge is price a punt – as the one OT vendor providing both (versus OT stalwarts like Rockwell and Schneider, with no pores and skin within the recreation), and the one OT vendor providing each (versus IT outfits Cisco and HPE, at each tables, enjoying with completely different palms).
So how do 5G and Wi-Fi come collectively in Business 4.0? “It relies upon who you discuss to,” says Mai. “From my perspective, 5G is a buyer pushed enterprise – as a result of it’s infrastructure. Whereas Wi-Fi is extra like an OEM know-how – as a result of it’s out there in all places.” So Wi-Fi is a box-sale? “Precisely,” he responds, happening to elucidate that new factories are being constructed with each simply because Wi-Fi is well out there however hardly dependable and 5G is well dependable however hardly out there. “There will probably be a coexistence, after all, and we’ll put in each,” he says.
He tells how “many occasions” a manufacturing unit telephones up as a result of an AGV software, working for years, comes unstuck when new lights are mounted on the ceiling after which related to the community. “Impulsively there are points with interference. As a result of Wi-Fi makes use of unlicensed spectrum. That sort of factor occurs on a regular basis. However we’re additionally in a transition part with 5G – as a result of the ecosystem of machine suppliers will not be supplying property with 5G connectivity.” Proper, so 5G and Wi-Fi are completely different when it comes to their buy and set up; however what about their administration?
As a result of that’s what others say – that they are going to converge on the management-layer. That’s what the IT-5G distributors say. “Sure. As a result of they supply enterprise connectivity. Store-floor connectivity could be very completely different. In IT, you may have this CIA [information security] mannequin [prioritising confidentiality, integrity, and availability], say; whereas OT has an AIC mannequin, which prioritises availability. As a result of the lifecycle is completely different. We’re coping with robots and trains, which do their jobs for 20 years; not smartphones and laptops, that are out of date in three-to-five. There isn’t a rip-and-replace.”
Mai goes on: “IT/OT convergence is clearly occurring, however the OT half will probably be taken care of by the OT division. As a result of it’s a automotive producer making automobiles – and never an IT workplace with a manufacturing unit within the basement. Sure, the store flooring must push the information someplace; all of that’s occurring. However it’s going to principally go to the sting, and to not the cloud. And this concept of IT-driven enterprise-wide connectivity, I simply don’t see it.” However final yr, at this occasion, the head of Volkswagen’s IT division mentioned 5G must work like Wi-Fi. Is that appropriate? “Sure,” says Mai.
However how does that chime with what you’re saying – that 5G needs to be completely different, as far as OT stays separate from OT. It’s a little unfair, as a result of the Volkswagen presentation is remembered from a year-ago; however Mai troopers on: “It signifies that 5G must be as straightforward to deploy as Wi-Fi. As a result of 5G will probably be in each manufacturing unit – Wi-Fi for generic connectivity and 5G for essential connectivity. However it must be maintained by OT workers. As a result of they’re accountable for manufacturing. It’s not only a server that wants rebooting, however an entire manufacturing line – in a managed method.”
He goes on: “Which is one thing a normal IT division can’t do. IT and OT must collaborate, however the necessities are completely different. IT is a value centre, and OT is a revenue centre, and prices are all the time streamlined. Concord in OT comes with all-different distributors – as a result of you possibly can’t get all the things from one. However there’s a cause why corporations go along with a particular model of laptop computer or a particular service of their information centres – as a result of it’s simpler, and to allow them to swap between suppliers within the blink of a watch. Which isn’t how OT works.”
It’s forceful and attention-grabbing, even when time is up and we haven’t bought into the nuts-and-bolts of straightforward industrial-grade 5G administration for OT (and the way that tallies with a “customer-driven enterprise”). However the message from Siemens is evident, going again to the beginning: that it’s completely different to each different 5G vendor, hailing from the standard ICT and IT fields, exactly due to its OT heritage and know-how. Responding once more to the query about why Siemens is completely different within the non-public 5G house, Mai responds: “As a result of we construct factories – end-to-end. Connectivity is only a small half, an enabler – all the things else is what [all the other 5G vendors] are missing. That makes us distinctive, and a trusted accomplice.”
