Wireless Application Environment

The main idea behind the wireless application environment (WAE) is to
create a general-purpose application environment based mainly on existing

technologies and philosophies of the world wide web. This environment should
allow service providers, software manufacturers, or hardware vendors to integrate
their applications so they can reach a wide variety of different wireless platforms
in an efficient way. However, WAE does not dictate or assume any specific man-
machine-interface model, but allows for a variety of devices, each with its own
capabilities and probably vendor-specific extras (i.e., each vendor can have its
own look and feel). WAE has already integrated the following technologies and
adapted them for use in a wireless environment with low power handheld devices.

HTML, JavaScript, and the handheld device markup language HDML
form the basis of the wireless markup language (WML) and the scripting
language WML script. The exchange formats for business cards and phone books
vCard and for calendars calendar have been included. URLs from the web can be
used. A wide range of mobile telecommunication technologies have been adopted
and integrated into the wireless telephony application (WTA).

Besides relying on mature and established technology, WAE focuses on devices
with very limited capabilities, narrow-band environments, and special security
and access control features. The first phase of the WAE specification developed
a whole application suite, especially for wireless clients as presented in the
following sections. Future developments for the WAE will include extensions for
more content formats, integration of further existing or emerging technologies,
more server-side aspects, and the integration of intelligent telephone networks.
