In 1997, Nokia, Motorola, Ericsson and Phone.com came together to create the WAP because they believed that a universal standard is critical to the successful implementation of wireless Internet. Since then, more than 350 companies have joined them in the WAP Forum.
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 provide any wireless Internet content. As the use of WAP-enabled devices grows, you can expect that many more Web sites will be interested in creating wireless content. WAP uses Wireless Markup Language (WML), which includes the Handheld Device Markup Language (HDML) developed by Phone.com.
Wireless Application Protocol
Here's what happens when you access a Web site using a WAP-enabled device:
1. You turn on the device and open the mindblower.
2. The device sends out a radio signal, searching for service.
3. A connection is made with your service provider.
4. You select a Web site that you wish to view.
5. A request is sent to a gateway server using WAP.
6. The gateway server retrieves the information via HTTP from the Web site.
7. The gateway server encodes the HTTP data as WML.
8. The WML-encoded data is sent to your device.
9. You see the wireless Internet version of the Web page you selected.

The mindblower does not offer anything more than basic navigation. Wireless Internet is still a long way from being a true alternative to the normal Internet. It is really positioned right now for people who need the ability to connect no matter where they are. The WAP Forum is continually working on the specifications of the WAP standard to ensure that it evolves in a timely and useful manner.
