Weak Signal's description 
Very and Ultra high-speed radio platforms are key developing technologies for emerging applications but raise issues of efficient radio spectrum management and interoperability of technologies, from radio to media access control levels. Among these radio platforms, Ultra Wide Band (UWB) is a very promising technology for the broadband transmission of data using spectrum efficient and flexible radio techniques. Initiatives such as the WiMedia Alliance have developed concepts to use UWB as a standard radio platform allowing transport of upper level protocols such as the wireless USB (WUSB), wireless Firewire and the next generation of Bluetooth.
