A handsomely written article on real-world use of a Handspring Visor with the Xircom Wi-Fi card: the author, a college campus network administrator, roams about with his small-format device, keeping order through a stylus and foldable keyboard. It's a nice account of the technical possibilities and limitation in current generation equipment. Next generation interfaces and cards should radically improve the experience, which is already not so bad.
Network World dissects the 5 GHz standards problem: Europe's regulations for use of 5 GHz, which favor the HiperLAN2 specifications, spawned 802.11h. 802.11h adds to 802.11a the necessary power limitations and frequency monitoring for devices to conform to regulations. Ultimately, these are improvements over a (and b and g), so should lead to 802.11h as the dominant mode of 5 GHz short-range networking. The HiperLAN2 advocates continue to express their confidence in their spec, but with this regulation friendly 802 variant, it seems highly unlikely.
