Dell Inc. has refreshed its XPS laptop PC line and the Inspiron 1525 notebook, which now optionally have a built-in Wireless USB module. For an additional $150, customers can purchase the XPS M1330, M1530, M1730 and Inspiron 1525 notebooks with the new capability that enables computer peripherals and electronics devices - such as printers, external hard drives, mice, keyboards, digital cameras, and MP3 players - to connect to a system without a USB cable. Along with a built-in Wireless USB module, purchasers who select the new option will also get Belkin's 4-port WUSB hub. Wireless USB technology is based on the Ultra-WideBand (UWB) radio platform, which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters.
