Xircom announces availability of Springboard module for Visor with WiFi: this is a huge step forward, enabling 802.11b on a handheld. Most handhelds are currently limited by a serial port connector, or, at best, a low-speed wireless add-on. Being able to use a Visor at megabits per second will rapidly transform their utility from an organizer into a window on larger data structures and applications.
Mobilian announces a system that can decipher Bluetooth and WiFi in the same space: nice idea. It doesn't solve interference, it just more intelligently separates out signals and routes them to the appropriate devices. This is the cornerstone of offering combination Bluetooth/WiFi cards and access points.
