What will be the impact on M2M of announcement to shut down 2G?

August 8, 2012

AT&T just announced that they will shut down their 2G network no later then January 1 2017. They want to free up spectrum for mobile Internet network capacity. “Well in advance of this change, we will reach out to our relatively small percentage of 2G customers and offer them options to meet their needs” says a spokesperson to Fierce MobileIT. According to Berg Insight AT&T had 13.1 million M2M subscribers by the end of 2011. It is often stated that the 2G share of the M2M subscriptions are bigger then 90%. I don’t know the AT&T mix but it is likely that at least half of their 13 million subscribers use 2G.

PricewaterhouseCoopers recently made a study and found that 60 percent of wireless operators plan on decommissioning their legacy networks over the next five years. Their study would suggest that more operators would like to make similar announcements as AT&T.

M2M terminals are often expected to be operational 5-10 years which makes the choice of network technology difficult. From a capacity point of view 2G is often enough and 2G modules are cheaper than modules supporting 3G and 4G/LTE. Coverage of the 3G networks are often not as good as the 2G networks. It is far too early for LTE networks to take over. Support for circuit switched connections which are required when moving terminals from the fixed phone networks (PSTN) to mobile networks is only available in 2G. It will be interesting to see what AT&T’s announcement will do to customers, regulators and other mobile operators. And what about countries were mobile networks are all 2G?

I believe this is a challenge for the development of the M2M market. As far as I understand it, AT&T will have to subsidize the remaining 2G M2M customers to replace terminals or loose the customers to other operators. This new situation for ongoing and planned M2M projects might delay or in worst case kill them if the up-front investment becomes substantially bigger. This news also explains why M2M customers need over-the-air provisioned SIMs.


Tropos acquired by ABB – going for private networks

June 4, 2012

ABB acquires the Wi-Fi mesh pioneer Tropos Networks to strengthen its Utility Communications product group. California based Tropos Networks has delivered a large number of wireless metropolitan and campus networks over the last ten years or so and I would even say that they made Wi-Fi mesh a viable metro network solution to the market.

This acquisition by ABB is very interesting and underline the grande potential for especially smart grids but also other private network applications. Tropos has deployed private networks for applications like meter reading, ITS, mobile workforce, public safety, telemedicine, parking meters, etc.

M2M is required to solve the efficiency problems, the security issues and the sustainability challenges in the world. And many of these applications will use private networks for financial and/or security reasons. Each of these areas will develop to become ICT systems in the size of the Internet which is why really large global players invest early on. I suggest you keep an eye at GE, ABB, Siemens, IBM and similar players.

Interesting move ABB!


M2M for the rest of us?

May 18, 2012

M2M solutions using Mobile operator’s networks are growing quite aggressively. According to Berg Insight we have some 110 Million M2M SIM cards active today. But even if this impressive growth continues we will never reach the connected society within my life time unless generic, cost efficient, easy to install and use alternatives comes to market. It is not primarily a matter of communication technology – it is a matter of connectivity together with services enablement making it cost efficient to develop applications. Such solutions will use fixed or mobile wan connections to connect to the Internet.

At May 16 I stumbled over the first potential solution to the “M2M for the rest of us” solution – Electric Imp. They just left stealth mode introducing a line of Imp cards that can be installed on any electronic device to put it online and control it. The cards connect to the Internet and a cloud based service using Wi-Fi. In their own words: “take the best implementation of hardware, firmware and cloud service, build them into a single mass-produced product, and apply them to any device in the world”. The word Imp is borrowed from Arpanet’s Interface Message Processor. Developer preview Imp cards and developer kits will be available this summer and Imp cards will retail for $25 when available in the market. Electric Imp claim they have invented a solution for configuring Imp devices for Wi-Fi networks in seconds using iOS or Android smartphones.

I find this exciting since it sounds like Electric Imp has what it takes: a generic, cost efficient, easy to install and use solution for connecting things to the Internet. As an evangelist and investor in the early Wi-Fi days I am also exited to see bets on Wi-Fi in the M2M field.

Electric Imp has a great idea, strong founders, capable investors and address a massive market opportunity. Their success will be determined by how fast they will get hardware vendors to adopt their platform and put Imp-slots in their devices.


M2M over the top, so to speak

April 24, 2012

Services like Skype and Spotify utilizing the Internet just as a connection are often referred to as over the top services or OTT. Consumers normally love them but operators typically have a more complex view of them: great since they create demand for their IP services but not that great if they replace services the operators charge for. Most M2M applications are really tiny in terms of traffic generation which explains why over 95% of the mobile ones still use 2G. For mobile operators M2M is more of a subscription business than a data business today. It is hard to estimate how M2M solutions will impact data volumes since it’s a combination of actual applications and volumes of connected devices.

I always claim that the M2M consumer market is a great place to look for innovation and interesting examples to bring to the business market. One example is what could be referred to as M2M OTT, where vendors of connectable devices use people’s ordinary mobile devices to connect to the Internet and an application in the cloud or elsewhere. This can make the device cheaper and smaller to manufacture and use. By using for example Bluetooth to connect to the phone and leverage the existing subscription and data plan. Data from the device can be made available to an application somewhere typically adding no cost to the user. And no new revenues but more traffic to the operator. There are many examples of this in the consumer market today and the personal health and fitness segment is one worth looking at. A mix of books, trends, research, services and products has created a rapidly growing movement and industry. Dr David B. Agus’ bestseller “the end of Illness” and the sleep monitor Zeo are good examples. The Zeo is a complete system taking sleep analysis out from the labs. By connecting a Zeo headband to an iPhone or Android phone via Bluetooth, the sleep data collected is made available to an app for reporting. But the sleep history data is also made available to the user’s account at mysleep.myzeo.com where analysis, backup and other services are available.

Using the mobile devices for local collection and presentation of data and access, over the top, to an application and services in the cloud is a model we can use in other situations. There are obviously downsides having to deal with Bluetooth, phones running out of power or stolen etc. But for some applications this is a great model maybe also in the business environment. There is simply not one or two models for M2M but many, and it is important to carefully look at all possible approaches available when implementing an M2M project.


Local M2M Gateways

April 12, 2012
The mighty mobile industry is a major force behind M2M today. They have what it takes to connect things, they need to find growth beyond the six billion active SIM cards today and they are promoting the concept of M2M aggressively. But at the same time it is quite obvious that a lot of things will be connected without SIM card. We already have a lot of connected devices in the PSTN network, many electricity meters are connected using PLC or other wireless network technologies than the mobile networks and wireless technologies like W-Fi, Bluetooth, ZigBee and RFID are already used in many applications. Different technologies have their strengths and weaknesses, new ones are coming to market while old ones are fading away. But the concepts of wide area and local area networks remain. Generally speaking it takes technologies optimized for LAN or WAN to build cost and capacity efficient networks. Sometimes even a shorter range network structure is needed like a Personal Area Network.I believe the mobile networks will be used for some connected devices, especially moving things or if one want to avoid dealing with Firewalls. But more so as the preferred WAN solution for things connected to a local area network solution. I have come across estimates that one out of ten connected devices will have a SIM card and I think that could be a reasonable estimate. If Ericsson’s “50 Billion connected devices by 2020” would be reality, 5 Billion of them would have a SIM card. That is a lot more SIM cards than the 108 Million mobile M2M SIM cards that Berg Insight estimate are active today world-wide. But what about the other 45 Billion connected devices? How will they be connected and managed and how will relevant data generated by these devices become easily available for application developers and integrators?

The most immediate challenge for the M2M industry is to establish a rich assortment of M2M services enablers in order to make development and maintenance of M2M application more resource and time efficient. M2M Service Enablers will have different features and specialities and they can be deployed in three different ways: on top of operator connectivity services, as in-house solutions or in independent service providers.

But another very interesting area to be addressed is how to connect devices in a local infrastructure in order to enable resource efficient development, maintenance and monitoring as well as a structured way to deal with relevant data. I use to refer to “Local M2M Gateways” and I have started to look for clever ideas and solutions in the market. I am convinced there is room for a whole range of different products optimized for different situations, still providing a quite standardized interface to M2M Services Enablers. In some cases we need to connect locally using only one technology and in other situations we need to support a mix of several technologies. Connecting sensors or things with sophisticated embedded systems put different requirements on the Local M2M Gateways. The choice of WAN-connection, with or without backup, is yet another area where we will need different solutions. And whichever solution we end up using, it has to be cost efficient, easy to deploy and maintain and robust. These will be important tools when helping organizations to design relevant M2M solutions to meet their challenges and opportunities.


Services Enablers key to successful M2M deployments

March 23, 2012

A key challenge for the M2M industry right now is to enable time and resource efficient development of specific M2M applications to industries or even companies. As soon as the interesting devices are connected in a proper way, data needs to be collected, organized and combined with other relevant data in order to provide useful information to new or existing applications. Devices need to be monitored, alarms have to be taken care of and maybe even transfer of money needs to be handled. This is what is done in M2M Services Enablement systems – the key to successful M2M deployments.

The Services Enablement systems can be deployed in three different ways: as extensions to operator connectivity offerings, as independent services from a third-party or as an in-house service to support M2M initiatives. It seems obvious that devices in many cases will be connected using a mix of technologies which further complicates this issue. It is my experience that we always end up in different communication technologies for wide area networks, local area networks and personal area networks/short-range communications. And even though wireless most often is preferred when feasible, also fixed networks will be used onwards. Needless to say, it is challenging to build a Services Enabler solution and to choose which solution to use in a specific situation.

We need to make it easier for potential customers to understand and decide which type of solution to use in order to accelerate deployments of real M2M solutions. Six Swedish companies just joined forces under the name of “Swedish M2M Service Enablers” in an ambition to start work together on educating the market on the importance of Services Enablement solutions and to try establish some common language and even APIs. The collaboration is also an attempt to market the companies to customers and partners abroad.

M2M and SIM cards

February 8, 2012

With the GSM mobile phones came the SIM-card (Subscriber Identity Module) 1991 turning a subscription into a tangible thing that could be removed, put into another phone and stolen. Users could bring their GSM identity to another phone without involving the operator which is very convenient. By removing the payment relationship from the subscription and adding possibilities for pre-payment a brand new and very popular type of mobile service was invented. Adding some memory available for the user made it possible to bring data, typically phone numbers, along with the SIM card to another phone.

In the early days of mobile M2M operators sent single SIM cards in envelopes which added an administrative issue to the already complicated task of deploying M2M solutions. Today we have a range of solutions to deal with SIM cards for M2M deployments. Making SIMs smaller is important in the handset market and in some specific cases we can leverage this development also in the M2M market, but most often the size doesn’t matter. With iPhone4 came the micro-SIM and next in line is nano-SIM measuring approximately 12 by 9 millimeters, 30% smaller than the micro-SIM. The thickness of the nano-SIM is reduced about 15%. The standardization of the nano-SIM is expected to be implemented through ETSI by the end of the year and the first nano-SIM phones will probably hit the market 2013. This will help phone vendors create thinner devices and free up room for additional memory and larger batteries but unless we are dealing with really small devices, this will probably not be important for the M2M market.

A much more interesting development for the M2M market is the over-the-air (OTA) SIM update, accepted by GSMA earlier this year. This will enable device manufacturers to sell devices with SIM cards included from factory and provision the subscription afterwards in a secure fashion. Apple, Google and others have been pushing in this direction for obvious reasons but some mobile operators were quite negative to the idea. Now it seems like the M2M players are making this happen first. Industry expert Northstream predicted that the SIM cards will disappear in the cloud maybe already this year. In the M2M market this would make life much easier for vendors of things with embedded M2M connectivity. The M2M connectivity could be built in at manufacturing, associated with a specific operator at the local resellers and expensive field maintenance could be avoided as well. The OTA SIM will bring a lot of transparency to the mobile industry removing practical and financial barriers thus making life easier for everyone involved.


The 2G/3G dilemma – Comments by Martin Svensson, Tele2

January 31, 2012

“I would say that 2G is not going away anytime soon, but if you are concidering new M2M installations today I would definetly recommend going with 3G compatible devices and to use 2G/3G compatible SIM cards. There is no guarantee of a maintained functionality in 2G networks looking ten years down the road (a normal life span for many M2M installations), and 2G CAPEX and OPEX will decline with all operators. Even if you take a slightly higher investment initially using a 3G device you will avoid the risk of having to exchange both SIM card and modem during the life span of your installation. Besides, prices on 3G modules are dropping and are rapidly approaching similar price levels as 2G units. This is of course dependent on the life span of you M2M installation and the amount of data you need to transfer. From an operator point of view, I am curious of which industry will first make use of 4G networks and M2M to rapidly transfer streaming video for specific surveillance tasks or other data intensive applications.”

Martin Svensson, M2M Product Manager, Tele2

The 2G/3G dilemma

January 29, 2012

Today some 95% of the mobile M2M connections are 2G. It is absolutely natural since the functionality and capacity needed for most of today’s applications is fulfilled in 2G and the modules are substantially cheaper. An off the shelf 2G SIM card would cost around $3-4 per month plus $0,5-2/MB data transmitted (in Sweden) and CSD, GPRS and SMS is enough for most M2M applications today. But there are dark clouds in the horizon! We don’t know how far away or how fast they come forward, but they are definitely there. Let’s try look at what these clouds contain.

A typical M2M deployment would count on terminals to be in service more than five years, often 10 or even 15 years. That’s long time! It is about 20 years since the GSM services came to market, and betting on the same networks to still be there with great coverage and good service might be something to consider carefully. A customer service person at my previous mobile operator in Stockholm told me: “sorry but we don’t invest in the 2G network anymore”. One of my companies, Possio, help mobile operators to move analog devices from the fixed network, PSTN, to mobile networks using primarily circuit switched connections in 2G (CSD). They experience operators, one by one, deciding not to introduce any new CSD based services in their network. They keep the existing ones, but obviously not for ever. I believe CSD will not disappear over night but this is worth looking into when making the bets

The connect part of M2M is the least interesting and rewarding. It is the compute part that makes the difference. IP is today, by all means, the dominating communication platform across all industries. The IP development environment is solid and rich, application support endless and skill is really everywhere, from developers to support people. An M2M bet today should in most cases be built on IP and one should really try understand if performance in 2G GPRS/EDGE will be enough for making all wanted computing during the life cycle. It is easy to foul yourself when it comes to performance and capacity. My first business trip with IBM went to Copenhagen 1983 where serious old men unanimously stated that with this capacity nothing is stopping us any longer. This was an ISDN conference.

The end-of-life problem is always something to take into account. Module manufacturers normally bring to market new pin compatible modules for their most popular models. But one day they will issue an end-of-life notice and then it is last order date and finally the spot market to rely on before it is over. In other words, when a market decrease it’s a chicken race between the module vendors. They not only want to understand how fast the market disappears (remember they have good numbers to watch) but they also want to ensure the best moment to bring their customers forward on a new platform and not lose them to a competitor.

The cost of modules for 2G or 3G differs a lot. As of today a 3G module would be roughly double the price of a 2G module and the difference could be $25-30. That is a lot especially if you need many. But it is important to look at the entire cost envelope, both capex and opex, over time. The cost of the actual deployment is normally high since it takes human beings to prepare the installation, to ensure other people involved are available, to get and verify permission for entrance and finally to go on site. Each installation is obviously different depending on industry, security levels, distances, type of application, etc but it can easily take a couple of hours per terminal which would translate into hundreds of dollars. One of my companies is active in retail environments where they often experience a lot of problems especially with access permission and coordination with other people needed (electricians, operator staff, alarm staff, etc). This is why we need to get it right first time – we can’t afford to go back – and why the installations will have to be operational for many years. When planning an M2M solution this might well be the most important aspect of the business case and the biggest risk for failure.

I believe this question – should I stay or should I go – is very important for all of us in the M2M business. There are no generic answers to the question about going 2G or 3G but it seems inevitable that sooner or later 3G will be the primary network why focus and investments thus quality and coverage in 2G networks will erode. How fast this happens is of course also depending on geography. In order to put more light on this important question I will ask a couple of knowledgeable individuals from within the industry about their views and post them here.


Networks for M2M today

December 14, 2011

What networks are used for M2M applications today? We know a lot of applications use the fixed network (PSTN) but I lack data on that. I visited a friend with a quite small but modern grocery store the other day and beyond the main connection provided by headquarters for cash registers, computer systems, telephony etc, he has three separate PSTN lines to his shop: one for a video surveillance system, one for recycling machines and one for an alarm. When talking to a friend at a fixed line operator recently he mentioned that they have energy companies with water power plants with thousands of PSTN subscriptions for level gauges.

The 2G networks are by all means the most utilized mobile networks for M2M today. Beecham Research claims over 95% of M2M applications use 2G today. Good coverage, reasonable prices, limited capacity required, affordable modules and history explains this situation. And despite push for 3G from vendors and operators, not a lot is happening except for some specific applications. Vendors obviously want to sell new products and some operators want to re-use 2G spectrum or move users for other reasons. For people developing or operating an M2M solution a key question must be to understand when the time is right to change from 2G to 3G (if ever) and how to implement the change. A clear detailed roadmap could be a competitive edge for an operator. Interestingly enough some, primarily vendors and operators, already claim 4G is the way to go for M2M.

Most of Ericsson’s modules business ended up in ST-Ericsson some years ago and they re-entered in 2007 to provide cost effective broadband modules to be built into PCs. Quite silently they announced the end of their broadband modules business in December 1, 2011. The reason provided for the exit was: “our position on the market does not provide the scale we need to achieve the desired profitability”. I believe the actual size of the market for 3G modules also is part of the explanation. ABI claimed last summer: “USB configurations are outselling embedded modems by a ratio of more than three to one” and expected USB configurations to stay bigger until at least 2017.

3G has been around for some ten years now and in dense populated areas it is heavily utilized and 4G is starting to be deployed. But in rural areas most people relay on 2G (some even don’t have 2G) and in some developing countries they haven’t even started to deploy 3G yet. In the end of the day it is market requirements that decide when and to what extent networks will be built, upgraded and utilized, not operator or vendor desire. Still today most M2M applications don’t need much more than decent connectivity (I don’t include Pads, tablets and Smartphones in M2M), and for these to go 3G we need competitive coverage, prices and module prices compared to 2G.
