Every computer and telecom vendor offers a partial product line that supports select wireless networks and application types. As Internet developers try to serve the totality of wired and wireless devices, they need a model for all wireless devices that unifies them from a programmer's point of view.

To reign in the madness of the confusing landscape of wireless devices, it's helpful to look at six major wireless Internet device classes: web phones, handhelds, pagers, voice portals, communicating appliances, and the web PC. This article takes a close-up look at these devices and discusses what to expect from them and the emerging wireless devices.
