4. Initial difficulties put the brakes on development!

While healthcare is a critical area for data communication and sharing, constraints linked to the protection of privacy and personal security explain why the development of large-scale networks is today essentially limited to logistics on the one hand, and wellbeing and activity data on the other, and why even fewer single-function networks are controlled by a healthcare establishment or group.

In other sectors, the miniaturization of sensors is enabling the development of sometimes vital applications – such as those that have begun to equip trains and automobiles, enabling the prediction of incidents on different parts. The local network that sends information to a central on-board system, and from there to an external system, is itself an instance of the IoT. A human being equipped with sensors and internal communicating devices and linked to information on the...
