The relatively small size of the LCD on a cell phone or PDA presents another challenge. Most Web pages are designed for a resolution of 640 by 480 pixels , which is fine if you are reading on a desktop or a laptop. The page simply does not fit on a wireless device's display, which might be 150 by 150 pixels. Also, the majority of wireless devices use monochrome screens. Pages are harder to read when font and background colors become similar shades of gray.
Navigation is another issue.
You make your way through a Web page with points and clicks on a mouse, but if you are using a wireless device, you often use one hand to scroll keys. WAP takes each of these limitations into account and provides a way to work with a typical wireless device. Inc. All rights reserved.
