Adding wireless comm capability to embedded systems

What is an embedded system?
An embedded system refers to any electronic system that uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. Embedded systems generally use microprocessors, or sometimes custom-designed chips or both. It is used in various applications such as vehicles, machine tools and consumer electronics.

What is wireless communication?
Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires." The distances involved may be short (a few metres as in television remote control using infrared light) or long (thousands or millions of kilometres for radio communications).
