M2M device

Definition
M2M devices (machine-to-machine devices) are devices that are

"in constant communication with each other (using wired and wireless networks) without human intervention."

Overview
"By 2020, the connected device market is expected to be dominated not by mobile phones, as it is today, but by machine to machine (M2M) devices &mdash; as many as 50 billion of them, by some estimates." A recent study claimed that M2M will generate new revenues and business models as well as enhancing the efficiency and effectiveness of current services, leading to a global business impact worth up to $4.5 trillion. "Examples of the economic impact include expected savings of $1 trillion by replacing manual meter readings with smart meters and another $1 trillion from service improvements such as providing clinical remote monitoring for patients with chronic illnesses." }}
