Getting familiar with wireless technologies

Feeling pressure to put data into the palms of your remote workers? Fear not, according to an Infoworld Test Center Analysis of the iSeries' potential as a wireless server. It fits well in the world of wireless communication.

Your wireless network will most likely depend on the Wireless Application Protocol (WAP), a successor to HDML. WAP's encoding language, Wireless Markup Language (WML), adapts XML to the small displays on handheld devices. Orubeondo and Fielden recommend AS/400 programmers learn "WML, scripting and the WTA (Wireless Telephony Application) framework" unless they want to hire an ASP to do the work for them.

Start your research with Joanie Wexler's newsletter, Wireless in the Enterprise. Wexler and WAP Forum CEO Scott Goldman discuss the new protocol in a two-part Q&A session. In Part 1, Goldman offers a glimpse at WAP products in development. And in Part 2, he defends the specification against its critics. You can also download a June 2000 white paper about WAP from the WAP Forum.

Once you've got your bearings around WAP, you can get further into WML at the Wireless Developer Network. The site's WML tutorial walks readers through a sample document and demonstrates events and navigation, and data retrieval from server CGI scripts. The network also presents a less detailed look at WMLScript, a variant of JavaScript that provides client-side procedural logic for WML applications.
