8 things you should know about wireless mesh networks

8 things you should know about wireless mesh networks

Wireless mesh is a crucial part of successful IoT (Internet of Things) applications. But what is wireless mesh, what are the advantages of a wireless mesh network and how can your product benefit from this?  Here are the 8 things you need to know. 

1. What is a wireless mesh network?

A wireless network is an infrastructure made up of devices that are wirelessly coupled to each other. The devices help forwarding packets so that the network can cover a larger area without the user needing to think about setting up a dedicated infrastructure.

It is safe to say that wireless mesh networks will be the steppingstone for IoT (Internet of Things) rollout. Without wireless mesh networks, it would just be too expensive to roll out massive scale networks in entire buildings.

Wireless mesh topology

2. What type of devices are there in mesh networks?

Different technologies have different nomenclature, but usually there are three main types of devices;

  1. Gateways or border routers
  2. Mesh devices or routers
  3. Leaf devices

A border router, or a gateway, is the interface to the outside world, they may connect the wireless mesh network to a building Ethernet, or connecting to a cloud service via Internet, for instance via LTE or 3G.

A mesh device is a device that helps build up the actual mesh. They forward, or route, data to and from other nodes hence being the mesh backbone.

Leaf devices are devices that are part of the mesh network, but they do not help creating the infrastructure. They do not forward traffic on behalf of others, but they can communicate via the network. Leaf devices are often devices that needs to conserve energy due to constraints on battery.

3. What does self-healing mean?

A wireless mesh is self-healing if it can automatically repair itself when the environment changes. It could for instance be that a link between two nodes that worked perfectly fine an hour ago is now blocked by a bookshelf, a truck, or a steel door. The network will then automatically, without the involvement of any user, change its topology to be able to route the traffic a different path.

Wireless mesh topology

4. What is IPv6 and 6LoWPAN?

IPv6, or Internet Protocol version 6, is the most recent version of the Internet Protocol. It became a draft standard in 1998 and is intended to replace the commonly used IPv4 protocol. IPv6 allows for a much larger address space with approximately 3.4×1038 unique addresses.

6LoWPAN, or IPv6 over Low-power Personal Area Networks, is an adaptation layer that allows for the use of IPv6 in wireless mesh networks and other types of networks that are more constrained than Ethernet and WiFi.

By selecting a wireless mesh network that uses IPv6 you gain the possibility to use standard Internet protocols for many different applications, such as security systems, messaging protocols for sensors, etc.

5. Can wireless mesh networks be battery powered?

They certainly can! MiraOS offers unprecedented energy efficiency – allowing for fully connected mesh devices to run from a single battery for many years, even decades.

Not all wireless mesh networks are suitable for battery operation though, and some allows certain devices to be battery operated – while still requiring the majority of devices to have hard-wired power. You can read more about low energy mesh technology on our Knowledge page.

6. Are wireless mesh networks secure?

Rest assured that most wireless mesh networks indeed are secure. Mira networks uses strong AES encryption in the link-layer between devices with protection for eavesdropping, replay-attacks, etc.

IPv6 based wireless mesh networks, such as Mira, also supports end-to-end security mechanisms with banking-class cryptography.

New vulnerabilities and attacks are discovered from time to time; hence it is important that the mesh technology you choose supports over-the-air software updates to roll out security updates when they are needed.

7. Is there a standard?

There are many standards. Very few of them are compatible with each other. However, when using a wireless mesh technology that use IPv6 and 6LoWPAN, you can rest assured that your application can be compatible with any Internet protocol based standard – just a word of caution: some protocols are more lightweight than others, making them more suitable for wireless mesh networks, one such standard is LWM2M specifically designed to work from the tiniest device via Internet, to the cloud if needed. Other IP based protocols that can be used is CoAP, MQTT-SN, etc. You can read more about wireless standards on our Knowledge page.

8. Is it easy to install?

It can be – if you select a wireless mesh stack where this has been an important design criterion. At LumenRadio, with our MiraOS, you can make deployment easy using a standard smartphone from an app, either using Bluetooth for remote commissioning, or via NFC for touch-to-commission.

3 reasons to choose MiraOS

The world’s most resilient wireless mesh network

At LumenRadio we say that our operating system MiraOS enables the world’s most reliable and Future-Proof wireless mesh networks. We are, of course, a bit biased on this topic, but when put to the test, MiraOS outperforms its competitors.

We offer unique features based on patented technologies and in this blog post we will give you three reasons to choose MiraOS for your wireless products. 

Low power mesh

Ultra-low deterministic power consumption 

One of the main features with MiraOS is the ultra-low energy consumption allowing for battery operated solutions. At LumenRadio, battery-powered mesh has been a dedicated focus for our research and development department and during the last couple of years we have been pushing the envelope and set a new standard. 

Today, MiraOS allows devices to form a wireless mesh while consuming less than 16uA, which enables more than 15 years battery life-time in routing mode (based on an AA-sized battery). And a leaf node running on a coin cell battery can easily operate for 10 years, thanks to the even lower power consumption. 

This consumption is calculated when sending a 160 byte data message every minute. And as far as we know, no other wireless technology can today match this performance – truly enabling Zero Wire applications. In fact, the limitation in life-time primarily depending on the shelf-life of the battery, which today is limited to 15 years due to self-discharge.

If ultra-low energy consumption is vital for your wireless device, then MiraOS is what you need.

 

Concurrent Bluetooth

Run MiraOS and Bluetooth 5 simultaneously on the same radio

It has been a well-known fact that running multiple protocols with strict timing requirements concurrently on the same radio chip by time-sharing the radio poses a huge challenge. 

LumenRadio have solved this problem and with MiraOS it is now possible to, on the same chip, maintain a Bluetooth point-to-point connection in parallel with the ultra-reliable meshing network of MiraOS.

What this means is that interactions between a wireless product and a smart device are now possible at the same time as the wireless mesh network is being fully operational. Concurrent Bluetooth operation opens up many new use cases, such as intuitive and hassle-free commissioning and maintenance, locally extracting large data sets from devices (too large to send through the mesh network), or possibilities for end user interactions through a smartphone or tablet.

This feature unleashes our customers creativity for smooth, intuitive user experiences while not compromising on reliability and performance. 

 

Reliability

How to handle interference in congested radio environments

Today billions of sensors and actuators are being wirelessly connected and all those connected products together with e.g. smartphones and regular WiFi installations create an ever-increasing amount of radio traffic all around us. Standard technologies such as Zigbee, Thread and Bluetooth Mesh are all single-channel solutions, which means they are very vulnerable to interference as the frequency spectrum gets more and more congested.

At LumenRadio we have a unique way to handle interference through our patented Cognitive Coexistence technology. In our case we build a predictive model of the frequency spectrum in each individual device, predicting on a millisecond basis how the frequency spectrum will be utilized going forward – we always use the best available and least congested frequencies when we communicate.

This is done by real-time adaptive frequency-hopping – an agile method for prioritizing good (less congested) channels over bad (congested) on the fly and is the most efficient strategy for interference mitigation in congested environments.

And the only solution for wireless mesh on the market using this kind of technology is LumenRadio’s MiraOS. With our technology, our customers products become future-proof, as they will coexist along with other wireless equipment – not being interfered and not causing interference.

 

These are three of the reasons to choose MiraOS but there are many others. Read more about MiraOS here, or how to evaluate it here.

MIRAOS RELEASE 2.3: Concurrent MiraMesh and Bluetooth operation – a killer feature within wireless connectivity

With LumenRadio’s new release of MiraOS – their operating system known for reliable wireless connectivity, they have solved a problem that has been a well-known challenge for years. MiraOS can now run concurrent Bluetooth and MiraMesh seamlessly during operation, something that opens up for totally new possibilities, flexibility and cost savings for wireless products.

Bluetooth is today the number one technology for short range point-to-point connectivity for smart devices, but it is not suitable for creating a reliable building-wide network. It simply lacks the scalability and range needed to offer complete coverage of today’s commercial and industrial buildings.

The common solution to the problem has been to simply add two wireless chips into the product (a Bluetooth-chip for user interaction and another chip for the building-wide network) – adding cost, hardware size and complexity and increasing the power consumption of the device.

In the connectivity industry, it has been a well-known fact that running multiple protocols with stringent timing requirements, concurrently on the same chip by time-sharing the radio, poses a huge challenge. LumenRadio’s Research and Development team has through dedicated and hard work now cracked the nut and solved the problem. Through the latest release of MiraOS it is now possible to, on the same chip, concurrently combine Bluetooth with the ultra-reliable, low energy, IPv6 capable, meshing network of MiraOS.

Enabling smart device interactions

What this means is that interactions between a wireless product and a smart device is now possible at the same time as the wireless mesh network is being fully operational. Concurrent Bluetooth operation opens up many desired possibilities such as intuitive and hassle-free commissioning and maintenance, locally extracting larger data sets, or possibilities for end user interactions through a smartphone or tablet.

User interactions on the edge within a smart building solution is becoming increasingly important, as we see a trend where workplaces, buildings and production flows are no longer static – rather dynamic, with a need to allow more frequent and easy user interaction with all kinds of equipment. Local control loops can enable individual preferences, something that tomorrow’s activity-based workplaces will require.

“Enabling concurrent Bluetooth and MiraMesh connectivity will give our customers the best of two worlds. This feature can unleash their creativity for smooth, intuitive user experiences while not compromising on reliability and performance. Life at the edge will never be the same again.” Niclas Norlén, CTO, LumenRadio

“Combining Bluetooth and ultra-low energy 6lowpan mesh operation concurrently in the MiraMesh stack has been a complex challenge to solve. Knowing how hard it is to run multiple protocol with stringent timing requirements, concurrently on the same chip makes me even prouder of my team. The knowledge, effort and hard work they have showed in this project is impressive.”
Michael Karlsson, R&D manager, LumenRadio

At LumenRadio we see an ever-increasing demand for concurrent Bluetooth operation and by adding this to our MiraOS we offer the most reliable, low energy consumption and Future-Proof wireless technology on the market.

As cool as “Beam me up, Scotty”

Bluetooth is today the number one technology to connect your peripherals. It can be found in any smart device out there, but when it comes to smart buildings… the Bluetooth point-to-point technology is not suitable for creating a reliable building-wide network. But what if you could use Bluetooth together with your reliable building automation technology? Wouldn’t that be as cool as “Beam me up, Scotty”?!

The classic scene from Star Trek was breathtaking for kids in the seventies. The coolest technology you could ever imagine. Maybe we are not there yet, but technology is developing at a rapid pace and cool things are happening everywhere – and definitively at LumenRadio!

Bluetooth is a well-recognized standard and has been around for years, allowing you to connect your smartphone to everything from your car entertainment system to your headset. It is the number one technology to get a point-to-point connection but has its shortcomings. To have a reliable meshing network in a building with thousands and thousands of nodes, you need a more reliable, energy-efficient meshing technology.

At LumenRadio we offer ultra-reliable wireless connectivity, verified and proven by some of the most well-known companies within HVAC, Smart Lighting, Physical Security & Access Control and Industrial Sensor Networks. Our MiraMesh communication stack together with MiraOS is the most energy-efficient and reliable connectivity technology available according to our customers. But, our technology has not yet found its way into the smartphones we all carry in our pockets.

A smartphone is the perfect device for commissioning, maintenance and user interaction for your wirelessly connected products. Imagine always having your control device in your pocket, no need for extra equipment in the form of a dongle, a custom tablet, etc. Imagine combining the world of an ultra-reliable, low energy and building-wide wireless mesh technology with the simplicity and flexibility of a smartphone app. Easy some say: “Just add two radio chips!”, but that is hardly a cost-efficient, viable solution. Imagine combining the technologies on the same chip – can the best of both worlds be combined for parallel operation?

Would concurrent Bluetooth and MiraMesh operation be possible? Well as we say at LumenRadio, challenge accepted!

Low energy mesh: The new industrial era

I guess nobody has missed that LumenRadio recently not only outperformed the competition, but also set a new standard for low energy mesh technology. Let us explain in detail what this means for Industry 4.0 and what incredible benefit it may entail for your business.

Real-time condition monitoring of critical equipment is a rule rather than an exception. At the same time less critical functions are disregarded due to cost or complexity aspects. However, sudden failure of these unmonitored assets might cause major damages to equipment, unplanned shutdowns or slowdowns with large expenses as a result. Actually, it is the installation of wireless sensor networks that is predicted to grow at an exponential rate over the next few years and among the fastest-growing sensor types are the simple temperature sensors*.

Many of you reading this are probably familiar with the tough requirements that need to be fulfilled to receive IP, IECEx and ATEX-certification for industrial devices. These certifications defines the essential health and safety requirements and conformity assessment procedures to be applied so that critical applications are protected in demanding environments.

 

Zero-wire sensor solutions

After these devices are installed and put in operation in Hazardous Locations, they must not be opened or affected – hence changing batteries after a few years in operation is not an option. You don’t want to put anything at risk in an explosive atmosphere and the products need to be designed to withstand extremely harsh conditions during its complete life cycle. This is one of the main benefit with having wireless products running in industrial applications; eliminating the need of changing batteries through the whole lifecycle. A technology which solves this problem is in strong demand and by some it’s considered a dream – we just made it a reality.

By releasing improved ultra-low energy consumption for battery operated solutions, we made it possible for industrial players to break new ground and take the next step within zero-wire sensor solutions.

 

Low energy mesh for sensor technology

MiraOS v2.1 enables ultra-low energy consumption for battery operated solutions. The current consumption for meshing nodes is now reduced to less than 16uA, which enables more than 15 years operation in routing mode from an AA-sized battery.

MiraOS enables low-powered sensor technology to become smart and connected through large-scale wireless mesh networks. Finally, product manufacturers can get an ultra-reliable and Future-Proof wireless solution with the most resilient technology on the market – justifiable for a much broader range of equipment. Decreased energy consumption means that sensors and devices can be designed for industrial requirements running on small batteries for a complete product lifecycle. Another main driver of low energy mesh technology in battery powered devices is retrofit. Industrial machines are retrofitted with wireless sensors to attain lower installation cost, lower product costs and to have an increased service life of the product.

Low-power radio technology is a fundamental requirement in the design of communication protocol for wireless sensor networks. Only by doing that we can achieve autonomous sensor networks that are flexible and can be installed at low cost.

We have said it before – choosing the right wireless connectivity technology will be crucial for the future success of your business, so don’t settle for mediocre standards.

Become IoT ready with connected fixtures

Today, smart lighting and connected fixtures is on every luminaire manufacturers agenda and a quick time-to-market solution to become “IoT ready” is crucial in order to retain or create your competitive advantage. But how do you get smart and rid yourself of  connectivity panic?

 

10 years ago we discussed how and when the LED was going to be used and adopted by the market and many of us were surprised how fast the LED revolution happened. The revolution we see now is within connected fixtures and not only is smart lighting a strong trend for achieving sustainable buildings and energy efficient cities, but today, luminaires in general are expected to be able to do more than just turn on and off.  But the most pressing question regards how fast these new features can be implemented.

 

The LED revolution happened fast and this coming lighting revolution will progress even more rapidly – there is no time to waste. A quick time-to-market solution, to have your luminaires become IoT ready, is crucial in order to retain or create your competitive advantage. But how do you add value to your fixtures and have them become IoT ready now, without having the in-house capabilities and knowledge it takes to develop your own reliable radio communication solution? The answer to this problem is one of the “ready-made” products for easy integration on the market. But the fact is that an IoT implementation is a big change and it requires future possibilities and business development needs to be weighed in in the decision making. So how do you combine rapid time to market and the option to do future developments?

 

With Lumenradio’s AirGlow®, your fixtures will be IoT ready in a matter of minutes. But the main gain, which separates AirGlow® from other wireless lighting controls, is that AirGlow® has unique scaling abilities; it allows for light control of individual rooms but also the possibility to scale and allow for building wide control – all using the same product. This means that you can have your fixtures IoT ready in an instant, and still keep the options open for future developments and expand your offer further on – enabling even more ways to save energy and creating a better tomorrow.

 

Compared to other solutions, in almost every case, you have to choose between either a ready-made product for light control of individual rooms or an operating system for building wide control. With AirGlow® you don’t have to choose – you get both options!  

 

Want to know more about this unique scalability and how AirGlow® with minimum effort gives you maximum possibilities? Stay tuned for next blogpost or visit us at Lux Live (booth K11) to see AirGlow® in real life and stop by for a “Coffee and connectivity” chat.

Low Energy Mesh – Zero Wires for Zero Energy buildings

EU’s goal of making all buildings so called nearly Zero Energy Buildings (nZEB) by 2020 to reduce our carbon footprint creates a demand for low energy mesh technology in battery powered devices.

 

According to EU, buildings are responsible for approximately 40% of energy consumption and 36% of CO2 emissions. Currently, about 35% of the EU’s buildings are over 50 years old and almost 75% of the building stock is energy inefficient, despite this, only 0.4-1.2% (depending on the country) of the building stock gets renovated each year.

 

Environmental action

On June 19 2018 EU voted for a new revised Energy Performance of Buildings Directive (EPDB) where one of the six additions states:

Smart technologies will be further promoted, for instance through requirements on the installation of building automation and control systems and on devices that regulate temperature at room level.

Already by 2020 member states must transpose the revised EDPD into national law. This might sound too ambitious and even aggressive but we cannot wait any longer. We need to act now for our wellbeing of tomorrow and the planet we are living on. We need implement smart building technologies.

 

Retrofit

To be able to meet the revised 2020 binding EDPD legislation, a massive retrofitting and renovation of existing buildings must take place. A improvement of these old buildings energy efficiency will significantly reduce CO2 emissions and help us fight global warming.

At LumenRadio we are already seeing an effect of this ambitious yet necessary directive among our customers. For manufacturers within HVAC and Building Automation there is today a huge demand for retrofit friendly wireless technologies.

 

Zero Wires

With this massive retrofitting, the demand for wireless connectivity for sensors and control gears is exploding! But wiring all sensors and control gears will be very expensive and replacing the data cabling with wireless connectivity will only take us half the way. It has to be Zero Wires.

For instance retrofitting a sensor measuring Indoor Environmental Quality (IEQ) will be very expensive if you still would need a power cable. The only way of solving this is by choosing an ultra low power connectivity technology that let’s the sensor run on small batteries for years or alternatively utilizing small size low cost energy harvesting technologies.

 

Low energy mesh

With the MiraOS version 2.1 release LumenRadio has taken low energy mesh to a new level. Building wide battery powered meshing connectivity for building automation is now for the first time feasible. In the ultra low energy mode LumenRadio is pushing the envelope of what is possible.

A sensor part of a meshing network can be powered from a standard small size coin cell battery beyond 10 years sending 5 sensor messages once every minute! This is significantly better than any other competing wireless technology and enables battery powered products to run on the same battery through the whole lifecycle.

For us this technology push is a matter of saving the planet.

Let’s add some real Edge to the Edge

– A trend report from IoT Solution World Congress (IoT SWC) Barcelona.

What are the tech giants discussing, what is the IoT technology of tomorrow and what are the main takeaways from one of the leading  IoT industry events? Our CTO Niclas Norlén gives you his thoughts and reflections of IoTSWC 2018.

At this year’s edition of IoTSWC the trend was quite clear and even stronger than last years edition – all the actions happens on the Edge of the network. Today we are seeing the tech giants Microsoft and Google fighting for attention for their Edge technologies, whilst a few years ago the battle were rather about their Cloud technologies.

The intensified investments in Edge technology does not come as a surprise. For example the chip giant Arm predicts to have shipped 1 trillion IoT chips within a 20 year period. The majority of the ARM chips are used in applications at the Edge, in everything from sensors to gateways.

 

Crunching data at the Edge

So why this enormous investment and this massive amount of IoT chips prediction by ARM? I think it can be explained by just mentioning one of the cases I heard about at the congress;  The elevator manufacturer Schindler have 1.5M elevators connected on a global basis, each generating 2.5G of data every day. You can do the math but the conclusion is that there is an overwhelming amount of data that needs to be crunched every day.

Now ask yourself:
Where is the best place to crunch all this data? In the cloud, sending the data through a Telco? Or locally at the Edge with low latency and thus no cost for sending data to the cloud (which for Schindler would be a significant cost…)?

Well you’re right, the majority of all data has to stay at the Edge. And this is the reason why the “Cloud” giants as Microsoft and Google are making significant investments into what they call Edge technology. They are on a mission to make it easy to crunch data and send the data that brings value to the cloud. And all this data is generated by sensors many times having an ARM core.

The tech giants have extended their offering now not only covering operating systems and technology for the Cloud but also offering for the Edge gateway that normally has the processing power required for those operating systems.

 

A missing piece in the puzzle

But wait, there is a missing piece in the three piece puzzle Edge device (sensor) – Edge gateway – Cloud. This piece is one of the most important ones and the very foundation of IoT.

You need an operating system for the ever so constrained devices, devices which are is the very source for all data; an operating system for the sensors and actuators. In those constrained devices we often see the low cost CPU’s, the majority of those from ARM with the prediction of 1 trillion of devices within 20 years. Those CPU’s have very limited resources compared to the CPU’s in the Edge gateways. An operating system for those devices must have a very small footprint yet provide an easy way to develop an application for processing of sensor data.


The IoT tech giants offering stops at the Edge gateway today – the device with significant processing power that connects the sensors and actuators to the cloud. But even further to the left in the picture you have the real Edge devices that is the very source of the data – the majority of all devices are found here, the temp sensors, presence sensors and vibration sensors to mention a few.

 

Retrofit demands Zero Wires

But there is more needed from the operating system for the constrained Edge devices. There is a strong trend in retrofitting sensors and actuators especially within Smart buildings, driven by green legislations, and Industrial Sensors networks, driven by predictive maintenance. Two industries that got much attention at IoT SWC, having separate focus tracks at the congress. For this retrofitting to become cost efficient the devices needs to be Zero Wire, i.e. either battery powered or powered by energy harvesting technologies. This means that energy efficient hardware and an operating system providing an energy efficient connectivity and data processing (i.e. Edge Computing) is a must.

In our product strategy the retrofitting trend is one of the main driving force. Our R&D focus to stay on the cutting Edge of technology developing our ultra low energy operating system and an ultra reliable communication stack for constrained devices.

Leaving IoT SWC I’m even more confident that we are on the right path adding some real Edge to the Edge.
