Driven by the demand for "green" technology and better use of power, a new generation of extreme low power wireless networks is being developed for use in machine to machine networks, for industrial and control applications, as well as for health, security and other purposes. With this in mind, a new approach towards truly wireless networks is needed - one without any network cables or power lines.
It is possible to develop these types of wireless systems by utilizing designs that require very little power. These wireless networks can last longer than their batteries and can require little to no maintenance over the lifespan of the device. If the device does not require any batteries at all, a solution can be fashioned using energy harvesting to provide the power required.
