Foreword

It was with great pleasure that I accepted the invitation to write the foreword for this first of two books on M2M and Internet of Things, M2M Communications: A Systems Approach.

Although the market for Machine to Machine (M2M) devices and applications is still developing, we can already foresee that this technology will have a profound impact on our lives, as new application fields are explored. Numerous projections have been made for the growth of M2M: for example estimates include an increase from the current 6 billion cellular devices to eventually over 50 billion cellular-connected machines. Other estimates indicate the total market volume from M2M and Internet of Things reaching $11.5bn by 2012. Indeed the M2M market can already be segmented in numerous ways: distinguishing between hardware devices and software, between connection technologies, or according to specific industrial application segment.

Why are M2M markets taking off now, since many of the technologies used have existed for a number of years? A key factor in the growth of M2M today is the widespread availability of ubiquitous, low-cost connectivity. We have become used to cheap, high-speed home and business internet access. Now in many regions 3G and future LTE mobile networks offer similar access speeds at highly competitive prices. Suddenly a host of applications we have dreamt about and which require internet connectivity have become economically viable.

The large-scale deployment of IP-connected sensors, monitors and actuators, in the home and in industry, enables the development of new interconnected, interoperable services which hold the potential to transform our daily lives. M2M technologies offer a vision of mash-up applications founded in reality, utilising multiple new sources of information, in contrast to the virtual world of mash-up web services. This vision is sometimes referred to as The Internet of Things, but it's not the connected things which are important. Instead, what is important is the information which they provide us, and how we combine and present and use this information, and how we make decisions based upon it. The Internet of Things offers a technical viewpoint. We must look beyond that to see the societal impact, to understand how we will make use of this technology to change our lives for the better.

A key feature of this vision of the future is the variety and range of technologies, functionalities and requirements which we need to take into account. How can we develop a flexible architecture into which we can place today's and tomorrow's technologies? How can we enable interoperability? How can we preserve confidentiality and privacy of information while not restricting potentially beneficial new applications? How can we ensure the reliability of these systems we will build, as we grow increasingly dependent on them? The solutions to these challenges lie not with any one organization or individual. This requires cross-industry thinking, it requires collaboration between the different actors concerned and it requires co-ordination at an international level. Consensus-based international standards are essential to ensure the development of M2M technologies and markets, providing solutions to many of these challenges. ETSI's M2M Technical Committee is currently playing a leading role in driving international standards work in this domain.

Beyond the wider societal challenges, we also face many detailed technical issues. A rapid deployment and adoption of M2M technology will result in new demands being placed on our networks. M2M services often require high efficiency, low overhead, low power consumption and greater flexibility in networks. These requirements will compete with the demand for high speed, low latency and large capacity, which our networks are currently equipped to handle. We may need to re-think how we design and how we manage our networks, if M2M services become as widespread as forecast. We will need to consider new access technologies in order to enable new applications which are not well served by the current radio technologies on the market.

The growth of M2M applications will have a profound impact on the standards which define our telecoms and data networks. ETSI has many years of work ahead of it to develop the specifications and standards which will be needed. I am certain that this book and its accompanying volume will provide us with useful guidance in this task, helping us to better understand the issues we need to tackle in order to create an M2M-enabled world.
