A scalable range radio-communication interfacing for embedded systems

This paper describes the radio-communications ldquostate-of-the-artrdquo and ldquostate-of-the-practicerdquo for interfacing nodes in an ambient intelligence network. We also discuss the role of software defined hardware for software defined radios that form the radio-communication interface for ambient intelligence networks. Nodes must be capable of communication over at least one medium from Wibree-like (Bluetooth) to broadband satellite, preferably with flexible range and bandwidth. Wireless sensor networks and wireless ad-hoc networks based on these nodes provide a well-defined architectural basis for mission-critical and security-critical solutions.
