Hardware

All cellular M2M applications involve powering and interfacing to a modem. Cellular modems are available with a variety of interfaces, and form factors. For many applications, a surface mount module with a serial interface to a microcontroller is the most cost effective solution. In other applications, perhaps where the application includes an operating system, or is being upgraded from a wired connection to wireless a separate modem with a USB or Ethernet interface is more efficient.
