Wireless Internet

Probably the most important factor in the birth of wireless Internet has been the proliferation of digital cell phones in the last few years. The expanding network of digital cellular phones and personal communication services (PCS) has created a solid foundation for wireless Internet services. It is estimated that there are more than 50 million Web-enabled cell phones in use.

Making a Web site accessible through a wireless device is quite a challenge. So far, only a small portion of the more than a billion Web sites provides any wireless Internet content. As the use of Wireless Application Protocol (WAP)-enabled devices grows, it is expected that many more Web sites will be interested in creating wireless content.

Most cell phones and Web-enabled Personal Digital Assistant (PDAs) have data transfer rates of 14.4 Kbps or less. Compare this to a typical 56 Kbps modem, a cable modem or a DSL connection. Most Web pages today are full of graphics that would take an unbearably long time to download at 14.4 Kbps. Wireless Internet content is typically text-based in order to solve this problem.
