Web server
The Web server stores the applications written in WML. Alternatively, existing HTML
applications can be used.
HTML filter
Any applications written in HTML will have to be converted to WML before they are
sent to the mobile terminal. This HTML filter may form part of the Web server or the
WAP proxy.
WAP proxy
The WAP proxy acts as the gateway between the cellular network and the Internet
or Intranet. It encodes the information which is to be sent to the mobile terminal in
binary format and decodes information sent from the mobile terminal.
WTA server
The WTA server handles network-specific applications. These applications are not
discussed in this document.
