Nb iot vs sigfox

Low rate, cellular data-only plans have fallen dramatically in cost in many countries– I've seen some as low as $0.30/month being offered, although other operators are still trying to get upwards of $100/year. I would contend that if we want to get to the tens of billions of connected devices, data costs need to be free. That may sound shocking, but there are several good reasons for it: USE CASES Fleet Management Car Dealerships Smart Solar Farms Vertical Farming Waste Management Smart Boating. About Learn about our team's mission, values, and where we're located. LoRaWAN looks at a wider amount of spectrum than SigFox (and thus gets more interference). However, because it's looking for a very specific type of communication, the elevate noise due to a larger receiver bandwidth is mitigated by the coding gains. Practical link budgets are about the same for SigFox and LoRaWAN. Minimum Viable Products The Jumpstart Package delivers an interactive prototype in 2-3 weeks. What happened is that the industry became fixated with the concept of revenue today, rather than revenue tomorrow. As users embraced smartphones, their demand for data soared. When competing smartphone vendors made smartphone screens larger, mobile video took off, putting further pressure on the network's capacity. Everyone's attention became focused on how to build enough capacity into their network to retain their users. Instead of calling for new standards for M2M and IoT, operators started concentrating on how they could use their existing spectrum more efficiently. There was an easy answer to this– turn off their old 2G networks and use them for 4G, which supported around 40 times as many users. It was only as they started to do this that they belatedly realised that they were euthanising the only technology they had which would support the Internet of Things. At which point the LPWAN industry stepped into the frame and started cutting deals. The GSMA panicked, and directed 3GPP to embark on the path to NB-IoT. One is LoRaWAN, which has been deployed mostly in Europe. It has very small message capacity, as low as 12 bytes. While the number of connected devices continues to rise (and is expected to reach 125 billion by 2030 ), the maturing wireless technologies that support them are also continuing to get a good deal of attention globally. NB-IOT (Narrowband IOT), LoRa, and Sigfox, all low-power, wide-area network (LPWAN) technologies, are often pitted against one another in what's portrayed as a race to the top. But that's not necessarily an accurate picture of the connectivity ecosystem. Each of these technologies (or at least LoRa and NB-IoT) will likely play an important role in the IoT space depending on the use case, so understanding the features and differences of each is critical. One nice thing about LoRaWAN's open standard is its potential to be flexible—it's not going to be driven by a specific company. In practice, this does result in slower development, because you're developing standards by committee. Because NB-IoT is a cellular-grade wireless technology that uses OFDM modulation, the chips are more complex, but the link budgets are better. That means users get the high performance level associated with cellular connections, but at the cost of more complexity and greater power consumption. At $2 a year, 20 billion devices will contribute around 4% of current global mobile subscription revenues. That is probably less than network operators currently make from their GPRS subscriptions, yet it will replace much of that revenue. In other words, by supportin Read here for more information on the NB-IoT Physical Layer. Tell your users that their connected bikes will only work in certain countries and put SigFox modules in your bikes. SigFox offers more ubiquitous connectivity. Q: I sell connectected home appliances, what network should I use? A: You should stick to WIFI for now, if you're selling a connected door lock take advantage of the fact that it will be installed in house. You can always offer an option that has SigFox/LoRa as a fallback solution when the WIFI is down. Q: What if I have a LoRaWAN contract with provider A, but my device has moved to a location covered only by provider B. A: For now, too bad for you. Your device can't connect if provider B, does not allow it. However, the LoRa Alliance is already thinking about roaming and the possibility to route your device transmissions through another provider. Even in the first Ericsson document there were provisos about what would be needed to get to the 50 billion. They highlighted the fact that network operators would need to "combine technology with services for lower cost, faster time to market and reduced project risks". Power efficiency. Symphony Link's adaptive acknowledgement encoder allows nodes to transmit less frequently, which saves battery power and increases system reliability. 6 Reasons Smart Home Devices Malfunction and How to Repair Them. NB-IOT, due to much higher data rates, MAC sophistication, and higher power base stations, will offer more advanced features for routing, multicast, firmware broadcast, etc. LoRa is a proprietary modulation system sold by Semtech corporation. They are defacto the only chipset manufacturer or license holder for LoRa. NB-IoT is based on standard modulation types, but as is typical of 3GPP, there will be other IP license holders asking for money eventually. LTE-M has a big advantage, which is that the infrastructure is potentially already there. Most LTE base-stations can be upgraded to support LTE-M, so it's a no-brainer for network operators. The more pertinent question is when chips will be available to make low cost devices? Qualcomm has come to dominate the market for cellular baseband chips. It owns an extensive range of patents and has been driving innovation and complexity to force up the entry barrier and maintain its leading market position. Until very recently it has shown little interest in ultra-low cost, simple cellular chips. In fact it has largely destroyed the market for them. As a result there are no established competitors for LTE-M; the two main companies are both start-ups– Altair and Sequans. Qualcomm has just announced an offering, but the channel to support and sell to tens of thousands of different product companies is very different from their traditional one of working closely with a very few, very high volume manufacturers. LTE-M also contains a lot of IP, a fair chunk of which is owned by Qualcomm, which could prove problemati This is where we need to look at the economics. The vast bulk of IoT connectivity has a very different trajectory of requirements to consumer mobile. Smartphones have changed the dynamic of mobile ownership. Consumers are increasingly prepared to pay more for a smartphone, and in many cases replace them more often. But at the same time, they expect more and more data for the same contract cost. Networks have effectively become pipes. Press Read about Leverege in the news and follow our growth. The Really Hard Thing About GPS and IoT. (say, a couple of times in a day), and have to deliver top-notch battery lives at very low costs. In comparison, the. Symphony Link adds some vital connectivity features compared to LoRaWAN including guaranteed message receipt, firmware upgrade over-the-air, removal of duty cycle limit, repeater capability, and dynamic range. Machine Learning in 2019: Tracing The Artificial Intelligence Growth Path. like NB-IOT. The greater complexity of the NB-IOT network, the IP-royalty related issues ( since it works on licensed bands ), and the higher silicon area required combine to push up the total NB-IOT costs. What's more–. (practically any place that does not have strong, glitch-free 4G coverage). Since LoRaWAN does not rely on cellular data or wifi for functioning, its. Sigfox, the other LPWAN technology, offers a data rate of 100 bps– much lower than both NB-IOT and LoRa. standard that stays in operation in a LoRa technology environment. Taken by itself, LoRa The LoRa Alliance is an open, non-profit association formed to foster an ecosystem for certain LPWAN technologies. It has about 400 member companies throughout North America, Europe, Africa, and Asia, and its founding members include IBM, MicroChip, Cisco, Semtech, Bouygues Telecom, Singtel, KPN, Swisscom, Fastnet, and Belgacom. ' manner. There are two major variants of this specification– one released by. for functioning, while NB-IOT eliminates the need for the same. According to a senior official from Huawei, the NB-IOT infrastructure is set up by. . The LoRa technology does what it is meant to do well enough– but NB-IOT is easily the more efficient IoT protocol for '. LoRa is a proprietary modulation system sold by Semtech corporation. They are defacto the only chipset manufacturer or license holder for LoRa. NB-IoT is based on standard modulation types, but as is typical of 3GPP, there will be other IP license holders asking for money eventually. ', and simultaneously use the public network for off-facility information and activities. NB-IOT can be used in public models only. How to Unlock the Power of IoT Data with Visualization Tools. (the same thing is done in the LoRa architecture through gateways). While the LoRa gateways currently available are powerful and, more often than not, competitively priced, they are additional pieces of hardware that have to be managed– and hence, can be a potentially extra hassle. In NB-IOT, these are simply not required. One is LoRaWAN, which has been deployed mostly in Europe. It has very small message capacity, as low as 12 bytes. LoRaWAN uses unlicensed spectrum. In Europe this means a 1% duty cycle, which limits the volume and frequency of traffic, as well as the ability of the base station to control the network and send traffic down. The coverage would be very good. NB-IoT devices rely on 4G coverage, so they would work well indoors and in dense urban areas. The following sections will provide an overview of each of the LPWAN technologies. In the rest of this series, we'll devote individual posts to each of the options, taking a deeper dive into the various pros and cons of each. We'll also do a technical drill-down on their underlying technology stacks. ← Building Smart Cities With LoRa Technology: 15 Applications. CEO at Polymorph Systems, Director and Co-founder at Predictive Insights, Director at Bloodhound Technologies. All that said, the focus in IoT connectivity seems to have shifted. Are Sigfox and LoRa still competitors? Yes. But people aren't as focused on network technology these days—they're focused on use cases and applications. These technologies have been relegated to their proper place—they're tools, nothing more. Noticing this hole, a number of companies who had been developing proprietary, low cost, low speed, low power communication options saw an opportunity and created the Low Power WAN market. Whilst many perceived them as a group of Emperors with no clothes, the network operators were so desperate to have something to offer for upcoming IoT applications that they started engaging with them, rolling out LPWAN infrastructure. Whether they believed the LPWAN story, or just hoped it would fill a hole is difficult to ascertain, but no-one can deny that LPWAN is now firmly on the map, in the form of Sigfox, LoRa, Ingenu and a raft of others. To address that challenge to their hegemony, the GSM Association (GSMA) directed the 3GPP to assemble their own suit of imperial clothing which would be called the Narrow Band Internet of Things, or NB-IoT. It should be possible for a device to negotiate and "buy" additional data or services once it's connected by requesting a data upgrade from the operator, who will bill those pre-approved charges to a user, who could be a manufacturer, service provider or end customer. But that is application specific. What NIST's New IoT Publication (NISTIR 8228) Means For Your Devices. The second thing we need to look at is what a standard for wireless IoT connectivity needs to do? Most IoT devices will be quite taciturn. They will measure data and events and send that data a few times each day. They're not going to be streaming video or having lengthy conversations because they're battery powered. If they're going to run for several years on a small battery or some energy harvesting power supply, all they can manage is a few messages each day. Sigfox understand this and make it evident in their data plans. They're not talking about hundreds of Megabytes like the cellular industry, but as little as 14 messages of 12 bytes each day. That's about the same as a single SMS message. To put it another way, most IoT applications make text messaging look bloated. The LoRa Alliance believes that openness creates adoption, so members stress that anyone can join the Alliance and build hardware to support it. The trick here is how companies who adopt LoRaWAN can add value. Just like Sigfox, the LoRa Alliance wants network operators to deploy the LoRaWAN network—but they also want private companies and startups to do so. To allow for this, they've developed some discussion around roaming network to network. The business and technology around this idea isn't fleshed out yet, so one of the next steps will be to figure out how to allow for roaming from public network to public network and private network to private network. A comparative study of LPWAN technologies for large-scale IoT deployment. Sigfox is of the opinion that it's easier to work with mobile network operators or deploy networks itself and charge a small recurring fee than to sell expensive hardware at the endpoint. However, there are some challenges associated with this business model. For one, if you want to deploy a Sigfox network, you have to work directly with Sigfox—there isn't another option. Additionally, only one Sigfox network can be deployed in an area because the company has exclusive arrangements with network operators when they work together. SigFox is a French company that aims at becoming the first global IoT networking provider. It positions itself as an IoT network provider. Devices send their data through the network, SigFox handles the transfer of the messages through a HTTP callback to a pre-configured backend. SigFox: Radio properties SigFox is an ultra-narrowband technology that runs on sub-GHz frequencies on industrial, scientific, and medical ( ISM ) radio bands: 868MHz in Europe/ETSI and 902MHz in the US/FCC. SigFox: Coverage and infrastructure As of 2016, the SigFox network covers 23 countries and over 1.3 million km². The company deploys its antennas with the help of local telcos around the world. This means that you don't have to worry about setting-up the infrastructure. With Sigfox, you could use bidirectional command-and-control functionality, but to work appropriately, network density would need to be higher (due to the asymmetric link). Therefore, it is better for applications that send only small and infrequent bursts of data, like alarms and meters. LoRa is a proprietary long-range wireless technology standard that operates on the Industrial, Scientific and Medical (ISM) band radio frequency spectrum ( 863 to 870 MHz in EU / 902 to 928 MHz in US). It is a PHYsical layer (OSI Layer 1) protocol that offers a long range and low-power communication medium for machine-to-machine (M2M) and IoT applications [ source ]. LoRa technology was originally developed by Semtech, but it is now managed by the " LoRa Alliance ". Any hardware manufacturer can build LoRa modules but has to get a certification of compliance from the alliance. However, (as far as I can tell) radio modules are exclusively produced by Semtech for the time being. They've subsequently downgraded that, but very few in the industry noticed– for them, it's very difficult to discard the prospect of "tens of billions" once it's made its way into their business plans. Numbers that big get attention in boardrooms, whether or not they mean anything– they just sound so good that they are assumed to be true. The Things Network– a development community attempting to build a global LoRa network, is providing compatibility layers behind that which will stitch many of these gateways together. Costs will probably be slightly higher than Sigfox, but this will appeal to an open source community, with the innovation benefits that brings to an emerging technology. Most analysis of the market stops with the modem cost, but hardware is the easy bit. The next element of deployment cost is the provisioning cost. Within provisioning I'm including the cost of attaching the unit to the network, the cost of maintaining it and the cost of billing it. I'll come to the cost of data later. The LoRa name, LoRa logo and LoRaWAN are trademarks of Semtech Corporation or its subsidiaries in the U.S. and/or other countries. That argues, at least for the very low throughput devices which will make up the tens of billions, that the provisioning cost includes data for life. The network simply routes the data through to the cloud and takes it as a minimum up-front cost. Ideally, provisioning that will be blown in the chip, so that each piece of silicon comes with it. How that gets shared between operators is an interesting challenge, but it shouldn't be insurmountable. Coming to agreement will certainly keep plenty of lawyers busy for the next few years. No per-device configuration. One of the biggest frustrations you can have when deploying a different LPWA network is managing multiple per-device encryption keys at the time of production and on the server side. With Symphony Link, the host device configuration is the same for all devices of the same type, and key exchange is handled via our world-class, PKI-based Diffie Hellman AES architecture. This is the story of why NB-IOT was too late, why it will fail in the short term, why it will win in the long term, and why the industry will struggle to make any money from it. LTE-M– evolve an existing technology to make more money for network operators. That's not where the cellular chip industry has been going. In the early days of 2G, networks operated at two different frequencies, with relatively simple radio modulation. That meant that chips were moderately simple. Over time, the GPRS modules which are used in most current IoT devices have fallen in price to around $7. However, as the desire for more bandwidth has grown, 3G and 4G chips have become much more complex. Moore's law has helped to prevent them becoming exorbitant, but each new release of the standards has to support a growing number of frequency bands (we're up from 2 to over 70), as well as all of the different protocols in the previous standards which have gone before it. Developing these is prohibitively expensive. As a result, 3G modules cost around $20 and 4G modules $35. The growing complexity, which requires immensely complex protocol stacks to complement the chips, has benefitted a very few silicon suppliers, who have largely destroyed the competition. Qualcomm dominates, with Mediatek taking most of the rest of the market. The business model for both is to sell billions of chips to a small number of high volume manufacturers who have deep technical competence to integrate these into their products. That is very different to the model needed to support tens of thousands of IoT manufacturers who need $1 comms chips which they can just drop into their products.

That may seem like a downside, but it actually makes LoRa a good alternative to WiFi for low power devices that need to be connected throughout a building, like a factory or a hospital. (It's hard to find an IT department that would approve of putting a third-party device on its own network due to security concerns. Setting up your own gateway creates a completely separate and secure network.) Of the three technologies discussed in this article, it's the only one capable of being used as a "do-it yourself" technology; any company can build and use their own connected device wherever they can put up the gateway. Originally published on April 17th, 2017. Updated on August 17th, 2018. Once you have tens of billions of sensors connected, the absolute value of data from most of them will be close to zero. Adding a dozen extra sensors in your street may help the value of an application, but the value of the data from any one sensor is miniscule in its own right. If you had to pay for it, it would not be worth installing the sensor. By checking this box you are agreeing to have Leverege collect your email address and receive email communications from us. We'll never share or sell your information and will always keep it safe. It has faster response times than LoRa and can guarantee a better quality of service. One big advantage of NB-IoT is due to its simpler waveform: the technology consumes minimal power. Another big advantage is cost. By choosing chipsets specifically engineered for NB-IoT protocols, which have simpler construction, the overall component cost is reduced. Lastly, NB-IoT has potential advantages for smart city applications. LinkLabs predicts NB-IoT might have better building penetration compared to LTE-M. On the flip side, deploying in the US will be difficult because of the ubiquity of LTE, and since chips that also embrace LTE-M are often prohibitively expensive, you'd have to choose. But often it comes down to your specific use case; NB-IoT is probably best suited to static assets like smart meters while LTE-M has benefits in roaming applications such as vehicles or drones. Read here for more information on the NB-IoT Physical Layer. Energy Generating, collecting, and distributing energy more effectively. Put this together and you have a vision of a single chip which can be built into anything from a washing machine, an agricultural sensor, a cattle tag, a smart meter, a dog collar– anything that needs connectivity. As soon as it's turned on it connects, transfers data and continues doing so for as long as the device remains working. The chip vendor and the network operator get paid upfront and there's no ongoing costs, other than processing the data by the ultimate service provider. It gets the cost of connectivity down to a few dollars. Only then will we start to see the growth moving into billions. The LoRa name, LoRa logo and LoRaWAN are trademarks of Semtech Corporation or its subsidiaries in the U.S. and/or other countries. Team Fast-paced, curious, collaborative, and lovers of new technologies. Vodafone is trumpeting the first commercial NB-IoT network. At the same time, Sonera, in Finland is announcing the first commerical NB-IoT trial. Although that may seem confusing, there is no contradiction here. Both are telling the truth, as Vodafone is using Huawei's NB-IoT, which is totally different for the Nokia NB-IoT which Sonera is using. Nobody knows which variant will win. The key player in this could end up being Huawei. They have a captive silicon supplier in Hisilicon, which should help them get to the $1 chip price point. If they could persuade the Chinese Government to deploy hundreds of millions of devices in the country, this could make it the de facto standard. Nokia, Ericsson and Intel are unlikely to concede without a struggle, but with a higher cost and the lack of scale that a Government backed deployment in China could provide, they may struggle to gain momentum. This is where we need to look at the economics. The vast bulk of IoT connectivity has a very different trajectory of requirements to consumer mobile. Smartphones have changed the dynamic of mobile ownership. Consumers are increasingly prepared to pay more for a smartphone, and in many cases replace them more often. But at the same time, they expect more and more data for the same contract cost. Networks have effectively become pipes.

 TeleHealth: The Frontier of The Connected Device Market. Volume 3, Issue 1, March 2017, Pages 14-21 open access. With the growing options for connectivity, JP Meijers and I took a look at the comparison between each. The functionality is similar to SigFox in that it's primarily for uplink-only applications—data from sensors/devices to a gateway—with many end-points. Instead of using narrowband transmission, however, it distributes information across different frequency channels and data rates using encoded packets. These messages are less likely to collide and interfere with one another thereby increasing the capacity of the gateway. LPWAN Technologies While there are many LPWAN technologies and standards, we'll be focusing on SigFox, LoRa, Symphony Link, and Weightless, because these technologies are under active development or deployment. Although there are other proprietary protocols and stacks such as the Dash7 Alliance Protocol, they haven't gained as much traction and won't be covered in this article. LTE-M and Narrowband-IoT (also called "NB-IoT" and "LTE-M2," and explained beautifully here ) have recently emerged as new, big players in the space. With 5G sweeping over the horizon, the rapidly-transforming IoT connectivity landscape is poised for another major shift. It's crucial to understand both how LPWAN fits into that landscape, and how to weigh the costs and benefits of different LPWAN technologies in the space, in order to be well-prepared for future transformations in connectivity options. An introduction to the IoT Stack (part 2). SK Telecom deployed LoRAWAN for establishing IoT network in South Korea last year. coverage remains relatively steady across all types of locations. . Both the IoT protocols have their very own unique value propositions– and each has use cases which cannot be served by the other. One big advantage of NB-IoT is due to its simpler waveform: the technology consumes minimal power. Another big advantage is cost. By choosing chipsets specifically engineered for NB-IoT protocols, which have simpler construction, the overall component cost is reduced. Lastly, NB-IoT has potential advantages for smart city applications. LinkLabs predicts NB-IoT might have better building penetration compared to LTE-M. On the flip side, deploying in the US will be difficult because of the ubiquity of LTE, and since chips that also embrace LTE-M are often prohibitively expensive, you'd have to choose. But often it comes down to your specific use case; NB-IoT is probably best suited to static assets like smart meters while LTE-M has benefits in roaming applications such as vehicles or drones. LTE-M has notable advantages. First, it has higher data rates, which is important for data-rich use-cases. And unlike NB-IoT, the front-end is relatively simple. However, in addition to LTE being primarily a US technology, there are other limitations to consider. For one, we're still getting a sense of power efficiency with LTE-M. There are also draconian licensing issues to consider. Who wants to be paying firms like Qualcomm and InterDigitals to license cellular intellectual property? In general, larger economic and practical forces might shape the NB-IoT vs. LTE-M debate. We're likely to see major US service providers pushing LTE-M since they've already invested billions in LTE technology. By contrast, in the rest of the world where GSM spectra are the norm, we can expect to see a preference for the (non-LTE) NB-IoT protocol. How IoT Sensor Technology Is Disrupting Health Care. You can only manage what you can measure. (the corresponding figure in 2015 was just over $0.5 billion). While Semtech's.

Neither LoRaWAN nor Sigfox support upgrading firmware over-the-air natively, but Symphony Link economizes on resources by enabling security issue patches or new-feature or bug-fix management without human attention. The second thing we need to look at is what a standard for wireless IoT connectivity needs to do? Most IoT devices will be quite taciturn. They will measure data and events and send that data a few times each day. They're not going to be streaming video or having lengthy conversations because they're battery powered.

That's about the same as a single SMS message. To put it another way, most IoT applications make text messaging look bloated. Fair warning: A discussion on use cases isn't totally fair because, for most people, Sigfox is not an option—the network is not available everywhere. LoRa, however, is an option for most people because, with LoRa, you can set up and manage your own network. That aside, LoRa and Sigfox are equivalent when it comes to use cases, with a few caveats to be aware of. Most analysis of the market stops with the modem cost, but hardware is the easy bit. The next element of deployment cost is the provisioning cost. Within provisioning I'm including the cost of attaching the unit to the network, the cost of maintaining it and the cost of billing it.

How that gets shared between operators is an interesting challenge, but it shouldn't be insurmountable. Coming to agreement will certainly keep plenty of lawyers busy for the next few years. long-range wireless and more? Here are a few resources to get you started. Once you have tens of billions of sensors connected, the absolute value of data from most of them will be close to zero. Adding a dozen extra sensors in your street may help the value of an application, but the value of the data from any one sensor is miniscule in its own right. If you had to pay for it, it would not be worth installing the sensor. This brings us to the important part, which is what this means for network operators? Other than Vodafone, who have firmly nailed their colours onto the NB-IoT mast, most operators are hedging their bets by flirting with at least one proprietary LPWAN option. However, in order to get critical mass, contract prices are racing to the bottom. SK telecom is down to $0.30 per month and Sigfox's pricing will probably push that down to below $2 a year in the near future. That's a long way away from the $50- $200 that operators get from their current M2M contracts. What happened is that the industry became fixated with the concept of revenue today, rather than revenue tomorrow. As users embraced smartphones, their demand for data soared. When competing smartphone vendors made smartphone screens larger, mobile video took off, putting further pressure on the network's capacity. Everyone's attention became focused on how to build enough capacity into their network to retain their users. Instead of calling for new standards for M2M and IoT, operators started concentrating on how they could use their existing spectrum more efficiently. There was an easy answer to this– turn off their old 2G networks and use them for 4G, which supported around 40 times as many users. It was only as they started to do this that they belatedly realised that they were euthanising the only technology they had which would support the Internet of Things. At which point the LPWAN industry stepped into the frame and started cutting deals. The GSMA panicked, and directed 3GPP to embark on the path to NB-IoT. All of this implies a new generation of billing mechanisms which are paid upfront. These don't really exist yet and will take time to develop and deploy. The cellular industry has not got a good track record of innovation in billing, so I don't expect to see these deployed at scale for five to ten years. LPWAN providers also need to start with this new model. They should be faster to support this as they're not constrained by their existing systems, but it will still take time. If we want billions we need a totally new approach to provisioning, where we can get this cost down to a few dollars per unit. Get the latest IoT news and insights in your inbox. No per-device configuration. One of the biggest frustrations you can have when deploying a different LPWA network is managing multiple per-device encryption keys at the time of production and on the server side. With Symphony Link, the host device configuration is the same for all devices of the same type, and key exchange is handled via our world-class, PKI-based Diffie Hellman AES architecture. SigFox and LoRa are both good steps towards a more mature and ubiquitous IoT. Both offer a networking solution that fits certain use-cases and it is up to you to figure out which one suits you best. Other alternatives are on the market all fighting for a growing market share. We can list Neul, 6LowPAN, Thread, NB-IoT, etc. But during my Master's internship in SAP Labs, I have worked extensively with the SigFox and LoRa protocols especially their ( lack-of ) security features, where I have worked on IoT-specific end-to-end encryption.
