Mobile computing

Mobile computing is computing using a device that can communicate through a wireless channel. The field of mobile computing is as broad as traditional computing. Consumers expect the same convenience and computing power in the mobile device as in the computer which sits on the desk. Furthermore, mobility opens up new venues for interesting and unique products and services. Freedom from geographic constraints can allow a more effective, convenient, and timely use of computing and communication. As people tend to think and work in places other than at their office desks, mobile computing lets the computer be used as a tool where it is needed, not where it is tied by a wire. Examples include the executive working on a laptop while traveling and the field engineer having remote electronic access to technical documentation and diagnostics, as well as emerging applications such as automated inventory or baggage checking with RFID (Radio Frequency Identification Devices), and location-dependent services such as local maps or weather reports.
