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.
