Faster than Bluetooth or Wi-Fi, Ultra-Wideband technology can send data wirelessly over a distance of about 30 feet—perfect for streaming video or connecting to printers. The first product to use it is Belkin’s USB hub, which transmits several short pulses over a wide spectrum of radio waves to beam up to 480 megabits per second. Stick a receiver in your computer, and you can wirelessly zap info to MP3 players, scanners or any other USB device attached to the hub.
