Linux Powers First Handheld Software Radio

An anonymous reader writes "According to this article at LinuxDevices.com, Vanu Technology is demonstrating what it claims represents the world's first handheld 'software radio' using an iPAQ PDA running Linux at a conference in Washington DC today. Vanu apparently has implemented the signal processing functions on the iPAQ's XScale processor, and their software uses POSIX APIs to make it platform independent. Software radios implement multiple radio standards and frequency bands in software, rather than hardware. A standard iPAQ expansion pack houses the radio transceiver."
