Meridian (Extensible EDA) is a full-featured smartphone intended for enterprise applications, i.e. for any organization’s specified use. Possible applications include news reporting, warehouse management, courier tracking and technician assistance. The Meridian is small enough to be considered as a mobile phone, yet it boasts many properties of larger handheld devices, to satisfy a variety of business application requirements.

The Meridian now has a 2D Barcode Scanner which can be attached to the unit.

The Meridian provides flexibility and features not available in regular smartphones:

  • Internal expansion slot enabling the addition of application-specific hardware, such as a barcode or RFID readers, radio modems, varied measurement instruments, etc.
  • A choice of operating systems: Windows Mobile, Windows CE, Linux or Google’s Android
  • Customizable technical spec and form factor
  • Shock-resistant protection
  • Guarantee of long-term availability (5 years)

The Meridian’s functional content is identical to that of the latest generation of smartphones, including the wireless, satellite and cellular connectivity found in today’s devices. On the other hand, since it is designed to serve custom implementations, the Meridian offers the level of flexibility expected in the industrial (rather than the consumer) market.
