Benchmarking clarifies the future of internet of things.

Author:Harrop, Peter

IDTechEx has released a newly researched report, "Internet of Things 2017-2027", Benchmarking what went before, it finds that the most prolific electronic device is the anti-theft tag known as electronic article surveillance (EAS). This is because it is disposable and big retailers and libraries in some countries feel that it deters thieves. Over ten billion are produced yearly, mostly sold at around one cent with 0.5 cent ones available. There are three standards impeding sales because tags have to be replaced and often produce is defaced in that process when goods are rerouted to a different retailer.

Next comes disposable RFID tags which help stock control at around eight cents apiece. There is one standard portfolio for the highest volume applications. Both EAS and highest volume RFID took at least 20 years to get there.

Then comes mobile phones which are not disposable but they are mostly replaced within two years. RFID and mobile phones sell in billions yearly. EAS, RFID and mobile phones are not hard wired so there are no delays and costs from that but they all need infrastructure, in the case of mobile phones, widely deployed infrastructure. The EAS and RFID systems are usually operationally closed systems--only one service provider accesses them so their security is not a serious issue even though RFID often has internet backhaul. The phones are on more open systems and they are largely insecure but that has not impeded sales because the consumer benefits are so compelling.

Internet of Things nodes constitute IP addressed things that collaborate with things using the internet. The nodes that are operationally suitable for widespread deployment are tens of dollars each though they can be one or two dollars if improved and sold in very high volume.

If they are to be sold in tens of billions yearly they need to be ultra-low power and disposable, fit-and-forget. Indeed they will probably be self-fit as with dropping them from a helicopter onto forests for forest fire monitoring, snow for avalanche monitoring or tracking oil slicks at sea. One standard with interoperability please. Self-organising, self-healing wireless sensor networks (WSN) have not proved to be sufficiently scalable due...
