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.
