Internet of Things offer a bright but challenging future. At face value, Internet of Things (IoT) communications are simply devices sharing data in a wired or wireless network. For over 20 years they have been mainly one-to-one connections, recording events at remote locations such as changes in stock levels or temperature. That was then, this is now.Today, many communications service providers (CSPs) are excited by the possibilities of huge growth in traffic serving every business and social sector, from telematics that monitor vehicle performance and update in-car software, to smart meters advising providers of the utilities consumed, to controlling secure site access, to healthcare providers checking remote devices such as dialysis machines or even pacemakers.Iot networks already support a wide range of applications (47.7 million wireless connections worldwide in 2008, according to Berg Insight, and expected to reach 187 million by 2014). These applications are growing to include: critical health provision, transaction reporting (car parks, train tickets, toll roads, vending machines), and low value, low frequency service updates (such as industrial monitoring). IoT can present widely differing challenges in business models, technologies, implementation and support.In the first global magazine of its kind, IoT Now explores the evolving opportunities and challenges facing CSPs, and we pass on some lessons learned from those who have taken the first steps in next gen IoT services.
