Take predictive maintenance to the next level!

Many manufacturers are today looking at the possibilities of implementing predictive maintenance and embracing digitalisation. With this post we want to explain the importance of choosing a wireless connectivity that can take your predictive maintenance solutions to the next level!

Already in the 1950s the concept “condition-based monitoring”, CBM, was introduced in the industry to predict impending failures early enough to save components and over time the concept predictive maintenance has evolved. However, the final target is still to determine the condition of a machine and detect problems before they cause downtime. To me, the big difference between condition based monitoring and predictive maintenance is the amount of gathered data and how the data is used. Simply – The more historical condition based data that is available, the better and more accurate predictive maintenance can be done.

High installation costs

It’s easy to see the beauty in predictive maintenance and one may wonder why the method is not used everywhere when the advantages over planned maintenance are so significant. The simple answer is because of high installation costs. When the decreased maintenance cost is less than the increased installation cost the willingness to invest in new systems is very low.

Until now, wired sensor has been the only reliable alternative but it entails disadvantages such as purchasing of expensive cables, hours of installation work and limitation in scalability.  Not to mention all the instruments equipped with diagnostics about the process that is unused because of the difficulties it implies to install wired connections in the field. I could go on but I guess you got the point.

The right wireless technology

Now imagine if countless different sensors could be mounted wirelessly anywhere in a harsh industrial environment. All connected to each other in a perfectly applied meshed network,  running on battery or energy harvesting technology. Then picture yourself that the wireless connection is even more reliable and robust in comparison to wired solutions.

With LumenRadio’s Cognitive coexisting technology in combination with a meshed network and firmware-over the air updates (FOTA) this scenario is not fictive anymore but rather the reality of today.

With Future-Proof radio technology predictive maintenance will be applied more widely than ever. For the end customer, this means easier installation, lower installation cost, increased flexibility and scalability but also improved profitability as the service life of the machine will be optimally managed.

It is the ability to collect and process large amount of information that will boost your manufacturing. With wireless technology more sensors can be connected gathering more data for your decisions. More connected sensors implies a higher demand for interference management. This is why choosing the right wireless connectivity technology will be crucial for the future success of your business, so don’t settle for mediocre standards.

IoT Podden

Start with a tangible problem! – Latest episode from IoT-podden

How are the major Swedish manufacturing companies dealing with IoT and digitalisation and how can we strengthen the innovation process in the manufacturing industry? These were important topics at the Elmia Subcontractor tradeshow in november, a tradeshow dedicated to product development and purchasing.

The Swedish magazine Ny Teknik’s podcast IoT-podden was recorded live at the tradeshow and the focus was how small innovative tech companies can kickstart the bigger manufacturers IoT agenda. Three young and promising innovation companies with the aim to revolutionise the manufacturing industry with their IoT solutions were invited to discuss this topic. Alexander Hellström, CEO of LumenRadio was one of the interviewed as well as Carl Elgh from H&D wireless and Olof Samuelsson från Addsecure. All three shared the same view that Swedish manufacturing companies really need to ignite their IoT agenda by starting to evaluate new solutions today since there will be no time to spare regarding digitalisation if you want to stay ahead of the competition.

Listen to the podcast episode here (In Swedish) 




“The most important factor in digitalisation and enabling your product for IoT is to focus on solving real tangible problems. What challenges are your company, products and solution facing today and how could you solve this with new technique? Doing this you will early in the project have a solid business case to rely on. Then you can later on focus on the larger opportunity at hand by creating a broader more cross functional digitalisation agenda” – Alexander Hellström, CEO of LumenRadio.

“It is often believed Sweden is at the forefront, but reports shows that digitization is slow, and that Swedish companies are below the European average. This does not apply to all, but many Swedish companies in the manufacturing industry are approaching IoT in a rather slow pace. It needs to go faster – competition is rock hard now, especially from Asia and the United States” – Carl Elgh, R&D Manager at H&D Wireless

RC4 Wireless shines a light on Netflix’s Stranger Things

LumenRadio customer RC4 Wireless provides wireless lighting and motion technology for theatre, film and television. When they were recently asked by Netflix to solve a specific flashlight issue for the series ‘Stranger Things’, they turned to the most trusted and reliable wireless solution in the industry – LumenRadio’s CRMX technology.

With a title like Stranger Things, one might expect a world that’s intense, mysterious, and dark. And one would be exactly right. However, dark isn’t always metaphorical; the Netflix series often takes literal forays into the dead of night, darkened rooms, and ink black tunnels. When it was time to shine a light into the void, the Stranger Things lighting team turned to RC4 Wireless who offer customers the option of LumenRadio CRMX integration.

“On season two, we were told a couple days into principal photography that there was going to be a lot more lighting effects than season one, especially involving flashlights and other custom-build fixtures. Not only that, but we were going to need to start to modify the flashlights not just to flicker and pulse on command, but to swell and get brighter during the scene. And all of this had to happen in a much smaller package so it could easily be carried in a flashlight by multiple members of the cast,” explains Jeff Harkes, lighting console programmer — Stranger Things 2.

Stranger things flashlight

To make those flashlights work, Harkes and his co-conspirator on set, fixtures foreman Antimo Ponticello, turned to the LumenDimM2micro from RC4 Wireless.

“The LumenDimM2micro was a good choice for this project because it’s a Swiss Army knife for portable applications of this nature. Because of its size [2.9″ x .77″ x .4.3″], it is the obvious answer, but it’s also extremely responsive on a cue. The LumenDimM2micro’s CRMX integration through the LumenRadio transmitters and its ability to be remotely managed with RDM is unparalleled right now. There isn’t anything like it on the market for portable handheld lighting control,” Harkes states. The LumenDimM2micro features two channels of dimming, includes multiple PWM frequencies, as well as the majority of the RC4Magic harmonized design features that RC4 Wireless users know and love.

To create the flashlights, “We basically made it all fit into the flashlight sleeve and soldered it all back together so that the power signal from the RC4 dimmer was feeding the flashlight directly. That gave us full control to flicker, pulse, swell or dim the bulb on command all while allowing the actors to complete their actions unencumbered by wires up their sleeves or having to rely solely on visual effects to complete the look,” says Harkes.

Intensity control was also critical to the show. “This came in handy in a lot of applications — not only was Jeff able to run any effects he had programmed on the lighting console through the RC4 LumenDimM2micro we built into the flashlight, but we could also turn it off or dim the bulb down between takes to save the lithium batteries. Being able to dim the bulb would allow us to set the level for the camera and it took some of the responsibility of handling the flashlights out of the hands of the actors by letting us handle that remotely,” explains Ponticello.

There are over a dozen flashlights used on Stranger Things. Harkes notes: “Each flashlight across the whole show acted as its own separate project. No solution was going to work perfectly for all of the flashlights so each one had to be approached in its own way. However, in the end, every flashlight ended up using a LumenDimM2micro.”

This is the second year with RC4 on Stranger Things. Harkes explains: “In season one the work with the RC4 LumenDims started in episode one with the bike lights. Jim Dornemann, our dimmer board operator, wanted to use the RC4’s to control the lights on the bicycles remotely during the scenes. We did, and it went off without a hitch.”

As for the future, Harkes notes, “RC4’s products can really solve some of the common problems that we face every day in dealing with fixtures. Their technology is reliable and their customer support is very knowledgeable, helpful, and very quick to respond.”

“It´s great to hear RC4 getting well deserved recognition for providing the film industry with sensational products for special lighting effects and we are honoured to know that LumenRadio’s CRMX technology is helping to get the job done. RC4’s LumenDimM2micro is a fantastic product and its ability to be remotely managed with RDM makes unparalleled right now” says Roberts Larsson, Sales manager at LumenRadio.

Don’t let the connectivity solution determine your product’s end of life


Don’t let the connectivity solution determine your product’s end of life

Wirelessly connected products are found everywhere nowadays and wireless connectivity is on the top of many R&D managers’ agenda. At LumenRadio we are witnessing just that, we see an ever increasing demand for wireless. But you don’t want the wireless connectivity solution you chose to determine your product’s life cycle. It should simply work until the end of life of your product, right?

But there are some pitfalls to consider for sure! In this blog post I will discuss how to avoid them.

Wireless is exploding

I would say that almost everyone agrees that wireless connectivity is the future.

We see sensors and actuators being connected all around us. Wireless connectivity is exploding and is a key enabler technology for IoT. It’s not only us saying that, I mean after all we are somewhat biased at LumenRadio, we are passionate about perfecting wireless connectivity. So you wouldn’t expect anything else. But you can read this in reports from Ericsson [1] and Gartner [2], to mention a few. They are all pointing into the same direction – massive wireless connectivity lays ahead! Of course these are predictions and predicting the future is hard, it has always been. But the trend is pointing upwards, very very steep upwards. And it is all happening now!

Choosing the right connectivity technology

In this world of predictions, how do you make sure that you are choosing the right connectivity technology?

As I mentioned in an earlier blog post about The Frequency Spectrum: massive connectivity means massive use of frequencies. Your wireless enabled product might be working fine and dandy today. But imagine that a couple of years after your product was installed, a new wireless sensor system is implemented in addition, or the IT department decides to install more WiFi. If your system can’t cope with the new competition it will risk failing, resulting in poor quality of service. You can imagine the support burden when the customers start calling. This could very well lead to you having to redesign the product…

Firmware updates over the air!

Let’s move on to something that should be a given. Firmware updates over the air! It’s crucial!

I mean, what do you do if you implemented an undocumented feature? You know, a feature that product management would call a bug… Or imagine the same product management being über-excited about a new feature they want implemented, a feature that the customers just have to have. Imagine you have to say “not possible” Firmware updates over the air are crucial!

Does it work in real life?

But you need to watch out! Some vendors claim they have FW updates working, but we have witnessed quite a few systems that don’t work in real life. I would say that anyone can get FW updates over the air working in a lab environment for a few units. But what happens in real life when you have to update thousands of units and some of them are battery powered? Ask for proof before you buy into a vendor’s wireless connectivity solution!

FW updates over the air is a focus area for LumenRadio R&D. Even if you have thousands of units in the network, a FW update is just a push of a button away. Thanks to our patented method a FW update that can take hours and hours won’t drain the battery-powered nodes. These are not just empty words, we have proven ourselves in the field. For example this building, Torsplan 2 in Stockholm.

About 3000 wireless sensors and actuators installed are in the network. We stress-tested the system doing multiple FW updates, and it worked flawlessly in an environment where the frequency spectrum was saturated by other wireless systems. And you know what: FW updates were running in the background while the system continues to be 100% operational. The customer won’t notice any degradation of performance, just that great new feature. This is a result of years of research, development and testing at LumenRadio!

Frequencies, a scarce natural resource

I mentioned that the frequency spectrum is becoming saturated. Our Cognitive Existence technology excels even though the spectrum is saturated. The main reason for us to develop the Cognitive Coexistence technology was to be able to offer Future-Proof wireless connectivity. In this world of massive adoption of wireless connectivity and the explosion of mobile data, we have the technology that won’t keep you awake at night after a product launch. Our Cognitive Coexistence technology will make intelligent predictions of the future and adapt, always using the best available frequencies.

If you want the full details about our Cognitive Coexistence technology please see my blog post about Our most valuable natural resource – The Frequency Spectrum.

How will mesh technologies help you in becoming Future-Proof?


How will mesh technologies help you in becoming Future-Proof?

Some people claim mesh is the new hype, the new magic bullet. Why is that, and what is mesh anyway? And most importantly – how will it help in designing your products?

First we need to set the scene – what’s the situation when not having mesh? Well, think about your WiFi. To get good coverage and quality of service you’ll need to install several WiFi access points across a building, and tie them together though a building wide network (most commonly Ethernet).

Star Network_WiFi

[Star network -WiFi]

This approach is both labor intensive and expensive since there is hardware and wiring needed, with the sole purpose of creating network coverage.
An extremely important factor in these cases is the link range, since that will limit how far away a device can be from an access point.

Mesh networks on the other hand are networks where the devices themselves creates the coverage, and help forwarding the data. This eliminates the need for separate infrastructure; the devices will create the infrastructure themselves – reducing cost and complexity.
Since data is forwarded from node to node, the range from a device becomes less important, since the range now does not have to cover all devices, but instead is only required to cover the distance between two devices.

Mesh network

[Mesh network] 

Furthermore mesh networks are most often self-healing. In layman terms this means that if the link is bad (for instance due to a device failure or in case the surrounding environment has changed), the network will find a new route for the traffic. The network is thus not sensitive to changes made in the building. In other words, the network is future-proof!



With self-healing networks and no need for special infrastructure it easy to see why mesh is considered a magic bullet – it simply helps in creating Future-Proof systems.

Wireless spectrum

Our most valuable natural resource – The Frequency Spectrum

Wireless spectrum

Our most valuable natural resource – The Frequency Spectrum

/in  /by 

I bet you are in love with frequencies!

Well, maybe you are not aware of it yet, so let me tell you why you are in love with them and why frequencies are one of our most valuable natural resources.

Although my business card says I’m the CTO of LumenRadio I’m more of the CNFGO of LumenRadio. For those of you who don’t know, CNFGO stands for Chief Nerd Frequency Geek Officer….. And I just love frequencies!

They are the very foundation of all our wireless communications, and without them our modern life wouldn’t be possible as we know it.

So let us dig a little bit deeper into the wonderful frequency spectrum and how to utilize it. And above all: how to make your new wirelessly connected products Future-Proof.

The foundation of all wireless communications

I state that everyone is falling deeper and deeper in love with frequencies!

So what do I mean by that?

We are seeing a rapid adoption of wireless connectivity for IoT and M2M. Driven by new businesses, billions of sensors and actuators are being wirelessly connected. Every little piece of the usable frequency spectrum is allocated which the picture below of the US frequency allocation tells us.

US frequency allocation chart

Every colored box in the spectrum represents a specific application allowed to use that portion and nothing else. Applications like WiFi, Bluetooth, Mobile phones, TV broadcasting and military to mention a few. There is no frequencies left to assign. The only way forward is either to shrink the allowed frequency spectrum for one application for the benefit of another or allow coexistence of the two. That is, if those have the technical possibility to coexist.

But there is more: wireless mobile data is growing by 50% every year, at least according to the recent Ericsson mobility report [1]. The trend behind this massive growth is streaming video content.

Obviously everyone wants to use the frequency spectra to generate more business! That is why we all have this passionate love affair with the frequency spectrum.

And this is the problem!

The frequency spectrum is a limited natural resource! When we run out of frequencies we run out of them. You can not just place an order for more frequencies, when they run out they run out!

So what will happen in the upcoming years and how does this affect you?

Gartner predicts 20 billion connected devices by 2020 [2]. Ericsson acknowledges this in their mobility report, and they also foresee massive growth in mobile data.

Future frequency congestions

We are witnessing a massive increase of wireless connectivity in buildings, as smart buildings means wirelessly connected devices: Wireless sensors and actuators optimizing energy usage for lighting and HVAC, or wireless sensors for cleaning and resource utilization, just to mention a few applications. The majority of these wireless devices is going to use the heavily congested license-free ISM frequency spectrum, utilizing short range technology. Ericsson predicts that 15.5 billion devices will be connected using short range technology by 2022, which stands for 53% of all connected devices.

Mobile data traffic growth – Copyright Ericsson [1] 

The thing is that according to Cisco, 60% of all mobile data is offloaded to the well-known short range technology WiFi. WiFi utilizes the same ISM bands as sensors and actuators.

Clearly there are going to be massive frequency congestions in the ISM bands. Buildings are going to be the frequency hotspots, as this is where most of the mobile data offload to WiFi happens.

But how does this affect you?

The scenario you need to consider is that your new wirelessly enabled product can stop working due to congestion in the frequency your product was commissioned to. This would lead to a stop in your company’s revenue stream, and obviously it would cause huge problems and would for sure backfire to R&D.  

Things that work just fine today may be drowned in the future frequency noise if you don’t design for that future already today.

Massive research resources to solve the problem

Luckily at LumenRadio we just love to solve this problem, and have spent massive research resources throughout the years focusing on the frequency spectrum. We do this to perfect our patented Cognitive Coexistence Technology, with which we have years of field experience helping our customers with business-critical wireless connectivity.

Put simply, our technology scans the frequency spectrum and makes wise and cognitive predictions on what frequencies will be the best to use going forward. Our Cognitive Coexistence Technology has been proven extremely reliable and frequency-friendly in the most challenging environments. Everything from major Hollywood movie productions to massive building control systems with thousands of wireless devices. All of those are business critical applications relying on Future-Proof ultra-reliable wireless connectivity.
