M2M (Machine-To-Machine) Communications
M2M is short for ‘Machine to Machine’ communications. It works in a similar way to mobile phone communications (Human to Human).
M2M transmits data in real-time between machines automatically, and without human intervention.
Data can be transmitted both wirelessly and by fixed wired methods.
Applications of M2M technologies include remote monitoring of water levels; smart road signs and remote machinery monitoring.
Wireless technologies are generally the preferred method of transmitting M2M data, due to the flexibility of equipment location. Wireless technologies include low powered terrestrial radio transmitters, satellites, and the mobile phone networks.
