Machine-to-machine (M2M) communications

  • Unlike person-to-person (P2P) communication, M2M technologies involve communication between two devices.
  • The technology is basis for automated information exchange between machines.
  • It enables wired and wireless devices to talk to each other using sensors.
  • It is also a key component of the emerging Internet of Things (IoT) revolution.
  • TRAI acknowledged its potential in National Telecom Policy 2012.
  • Applications of self-communicating machines using M2M communications can be deployed in new-age infrastructure projects and various industry verticals such as smart cities, smart grids, smart homes, smart transportation and smart heath sectors.
  • Why on news? TRAI has recommended delicensing of chunk of spectrum in few bands to facilitate smooth roll-out of machine-to-machine (M2M) communications.
