M2M is the abbreviation for machine-to-machine, or technology that supports wired or wireless communication between machines. M2M is used in telemetry, data collection, remote control, robotics, remote monitoring, status tracking, road traffic control, offsite diagnostics and maintenance, security systems, logistic services, fleet management, and telemedicine.
The expansion of 2G/3G wireless networks across the world has made it far easier for M2M communication to take place and has lessened the amount of power and time necessary for information to be communicated between machines. These networks also allow an array of new business opportunities and connections between consumers and producers in terms of the products being sold.
Normally any communicating M2M device starts with a modem/ module from manufacturers like Cinterion, Sierra Wireless, Teli. These modems have all been type approved according to tests specified by 2G (GSM) or 3G (UMTS) standards, just like any mobile phone in the market.
