$1.4 Trillion Lost to Downtime. The Expensive Part Isn’t Always the Breakdown.

Fortune Global 500 companies lost an estimated $1.4 trillion to unplanned downtime last year, according to Siemens - 62% more than in 2019.

Yet Siemens’ research also points to a decline in the frequency of equipment failures.

So what’s driving the increase?

In many cases, it’s the time spent finding, diagnosing and recovering from the problem.

A conveyor starts running slightly outside its normal speed. A hydraulic system begins losing pressure. An electrical cabinet starts operating at an unusual temperature. A cooling system becomes less efficient.

None of these necessarily means the equipment has failed.

But each can be an early indication that something is changing.

Without the right monitoring, those changes can go unnoticed until the equipment stops or a protection system trips.

By then, the problem isn’t simply repairing the equipment. It’s lost production, delayed schedules, emergency maintenance and time spent determining what went wrong.

Condition monitoring changes that equation by giving maintenance teams visibility into how equipment is behaving before it fails.

The objective isn’t to predict every failure perfectly. It’s to give the people responsible for the equipment enough information to make a better decision before a small change becomes a large interruption.

Because when downtime costs this much, knowing that something is changing can be almost as valuable as knowing exactly what will fail.

R45 Billion a Year Vanishes to Cable Theft in South Africa. More Fencing Won’t Stop It.

Eskom, Telkom, Transnet and PRASA lose billions to cable theft and vandalism every year, while the wider economic damage from outages, delays and repairs has been estimated as high as R187 billion.

Transnet alone reported more than a thousand kilometres of cable stolen in a single financial year.

The usual response is more security personnel and better fencing. Those help, but thieves can cut cable in minutes, often in remote stretches where nobody is watching. By the time a patrol arrives, the damage is already done.

Technology can change that.

Distributed acoustic sensing can turn fibre optic infrastructure into the detection system itself. Cutting, digging, climbing or tampering creates a detectable vibration pattern that can be located along the line in real time.

Instead of discovering the damage afterwards, security teams can be alerted while it’s happening.

For infrastructure that stretches for kilometres, that’s a significant shift: from protecting the perimeter to monitoring the asset itself.

The Network Problem Mining Sites Didn't Know They Had

The idea that one network should handle everything on a mine site is starting to look increasingly outdated.

Look at what the major players are doing.

Epiroc expanded its private LTE and 5G alliance with Ericsson this year.

Sandvik has been working with Nokia on private 5G at its underground test mine in Finland since 2020.

Nokia is also working with Komatsu and Vale on private wireless deployments in mining.

Different companies. Different equipment. Different mines.

But there’s a common thread: connectivity is becoming application-specific.

And that makes sense.

An autonomous machine has very different requirements from a temperature sensor attached to a conveyor bearing.

A live video feed has very different requirements from a gas monitor that wakes up every few minutes.

A worker safety system has different requirements again.

Trying to make all of those devices behave as though they’re the same type of endpoint is an unnecessary constraint.

The interesting development isn’t simply that mining is adopting private LTE and 5G.

It’s that we’re starting to see multiple connectivity technologies coexist on the same operation, each doing the job it is suited for.

Private cellular for the applications where bandwidth, mobility and latency matter.

Low-power networks such as LoRaWAN for the huge number of devices that need to send very little data, very reliably, for a very long time.

And Wi-Fi where it remains the right tool.

That’s a much more interesting direction for mine-site connectivity than simply asking what technology comes next.

The future isn’t one network replacing another. It’s networks becoming more specialised.

When the Network Underneath Your Product Changes

Every company running 2G or 3G hardware in South Africa has the same deadline. Almost none of them are thinking about what happens when they all try to fix it in the same eighteen months.

MTN has stated that it aims to shut down its 3G network nationally by 31 December 2026, with the migration already being phased in region by region. South Africa's broader roadmap calls for 2G and 3G to be fully decommissioned by 31 December 2027.

For a device that only speaks 2G or 3G, that's a complete switch-off.

The important part for anyone with connected equipment in the field is not the final shutdown date. It's what happens before that date.

Networks don't necessarily disappear everywhere at once. As operators migrate customers and progressively retire legacy infrastructure, connectivity can become increasingly constrained in particular regions before the national deadline arrives.

That's why we think legacy connectivity needs to be addressed early. Not because every device needs to be replaced tomorrow, but because waiting until everyone needs to migrate at the same time creates an entirely avoidable bottleneck.

LTE-M, NB-IoT and Cat-1 provide established migration paths for many IoT and telemetry applications, depending on the device's requirements.
The expensive version of this problem is discovering the issue in the field, after a network has already been phased out in a particular area, with a fleet of devices that now needs physical intervention.

The better approach is to start auditing those devices while there's still time to plan the migration properly.

If there's remote equipment in South Africa that was designed around 2G or 3G, now is a good time to establish:

Does it still rely on that network?
Is that network already being phased out in the regions where the equipment operates?
Can the existing hardware be migrated?
And if it can't, how large is the replacement programme likely to become?

The goal isn't to panic about the shutdown. It's to start early enough that the industry doesn't create a bottleneck for itself when everyone tries to solve the same problem at once.

There was a time when a component with a long lead time was primarily a procurement problem.

Increasingly, we're finding that it can become an engineering problem.

We're currently dealing with exactly that situation on one of our products.

A key component has been quoted with a lead time extending to 15 January 2028 - roughly 74 weeks from today.

The component itself isn't obsolete.

It's still a valid part for the application.

But availability is becoming increasingly constrained as manufacturers encourage customers towards newer generations of their product families.

And that creates a difficult decision.

We can source the component through the open market at roughly twice the normal cost and keep the existing design moving.

Or we can redesign the product around a more readily available component.

Neither option is particularly attractive.

Paying twice the normal component cost affects the economics of the product.

Redesigning introduces engineering time, validation, testing and the possibility of creating another supply constraint somewhere else in the design.

The bigger issue is what this means for long-term product design.

When we design an industrial product, we'd like to be able to say that the hardware can remain supportable for five, ten or even more years.

But how much confidence can we really have in that statement when a component that isn't obsolete today can become difficult to obtain tomorrow?
We can design for longevity.

We can select components with established lifecycles.

We can qualify alternatives.

We can design replacement paths into the hardware.

But ultimately, we don't control the semiconductor manufacturers' roadmap.

A manufacturer can decide to move customers towards a newer generation, consolidate a product family, reduce production capacity or change how it allocates supply.

The component doesn't necessarily have to be obsolete for it to become a problem.

That's why component selection is becoming about more than electrical specifications, price and performance.

We're increasingly asking:

Can we source it now?

Can we source it at a reasonable cost?

What happens if it becomes constrained?

And what is our plan if the manufacturer changes direction?

The semiconductor landscape is making those questions increasingly important.

For us, the challenge isn't simply finding a component that works today.

It's designing a product that has the best possible chance of continuing to work, and remain economically supportable, years from now.

Because ultimately, product longevity isn't something an engineer can guarantee alone.

It has to be engineered for, and continuously managed.

Why We Built ELMOS

Generic embedded Linux distributions have made it easier than ever to get an embedded product running quickly.

For many applications, that’s exactly the right approach.

But industrial electronics can have very different requirements.

A device may be expected to operate for ten years or more, with limited maintenance, restricted resources and environmental conditions that are very different from those of a development workstation.

In that environment, flexibility isn’t always an advantage.

Purpose is.

When we developed ELMOS - Entry Level Minimal Operating System - we started with a simple question:

What does this device actually need to do?

From there, the system is built around the requirements of the product.

Every library, service and dependency has a purpose. Anything that doesn’t contribute to the operation of the device doesn’t need to be there simply because it is available.

This approach gives the engineering team greater control over the software environment, from the underlying system configuration through to the applications running on the hardware.

It also makes one principle particularly important:

Complexity should be intentional.

An industrial embedded system isn’t a desktop computer.

It doesn’t need thousands of applications, countless configurations or functionality that will never be used. It needs to perform a defined task reliably, efficiently and consistently.

That’s ultimately why we developed ELMOS.

Not because another operating system was needed.

But because the operating system is part of the product, and when the product has to operate reliably for years, every layer of that product deserves to be engineered with the same level of consideration.

Good engineering isn’t about putting everything into a system that it could possibly use.

It’s about knowing exactly what it needs, and leaving the rest out.

For nearly two decades, Keystone Electronic Solutions has been engineering embedded electronics for some of the world's most demanding environments - from mining operations and energy infrastructure to telecommunications, industrial automation and critical infrastructure.

We don't believe in off-the-shelf solutions or one-size-fits-all engineering.

Every product begins with a simple question:

What does this system need to do, and what conditions must it reliably withstand throughout its operational life?

That philosophy underpins everything we engineer. Ranging from custom electronic hardware, multilayer PCB design and embedded software to telemetry platforms, industrial monitoring systems, sensor technology, IoT platforms and ELMOS, our embedded operating system for purpose-built embedded applications.

With more than 100 clients served, our products supported these organisations across South Africa, Australia, North America, South America and Europe.

But geography and technology aren't what define us.

The distinction that matters is that we don't simply supply components. We engineer complete systems, designed to perform reliably, long after deployment, in the environments they were built for.

Over the coming weeks, we'll be sharing engineering insights, technical discussions, real-world case studies and behind-the-scenes perspectives on the work that goes into developing reliable embedded systems.

Whether you're an engineer, technology leader, manufacturer or simply interested in industrial innovation, we hope you'll find something of value here.

Because good engineering isn't measured by how impressive a product looks. It's measured by how reliably it performs when it matters most.
