White Paper Z600
26 September 2003
Push services
Businesses and service providers can “push” con-
tent or service indications to work groups and/or
customers. Examples of pushed content would be
mail alerts, messaging, news, stock quotes, con-
tacts, meeting requests, etc.
Support of XHTML
The WAP browser supports the markup languages
of WAP 2.0. It supports WAP 1.2.1 + XHTML
Mobile Profile 1.0 + WCSS (XHTML-MP), XHTML
Basic, a subset of XHTML-MP, IHTML, WAP Cas-
cading Style Sheets (WCSS), WML version 1.3 and
WMLScript. The subsets of the WAP standard
XHTML are supported by all major WAP browsers.
WAP pages authored in XHTML and WCSS can be
displayed in standard PC browsers such as IE and
Netscape. WAP pages authored in WML can be
displayed in WAP browsers only. It is preferable,
therefore, that developers use XHTML and CSS to
develop content as these are pure WAP standards.
WML and WMLScript are for backwards compati-
bility.
All of the basic XHTML and IHTML features are
supported, including text, images, links, check-
boxes, radio buttons, text areas, headings, hori-
zontal rules and lists. For IHTML also blink and
marquee, but not tables.
Support for cookies
Z600 has support for cookies (client based), an
application used by WAP sites to store site-specific
information in the browser between visits to the
site. Cookies give the site owner a possibility to see
when a person has visited their site. They also save
the user from having to enter the same information
(e.g. the password or user ID) more than once.
Cookies are often used by e-commerce sites
(shopping carts and wish lists).
Style sheets
Z600 supports style sheets offering content devel-
opers more control over the way their WAP pages
are displayed.
Sending bookmarks
WAP 2.0 enables the sending of bookmarks via
infrared as well as via SMS.
Provide settings
Using SMS messages, configuration settings can
be sent over the air, OTA, so that the user does not
need to configure the WAP access settings manu-
ally. WAP settings may also be customized by the
operator.
Adapt to phone type
The User Agent Profile function allows WAP con-
tent to be automatically optimized for the Z600,
ensuring the intended user experience.
Several bearer types
The Z600 accesses the WAP over a standard GSM
Data connection as well as over a GPRS connec-
tion (network-dependent services.)
Bandwidth efficiency
Unlike traditional Internet services, WAP services
are relayed to wireless devices as binary encoded
data, maximizing bandwidth efficiency. A GPRS
connection further increases efficiency.
Easy create for WAP
Creating a WAP service is no harder than creating
an Internet/intranet service, as WML and WMLS-
cript are based on well-known Internet languages
such as HTML and JavaScript.
Using standard tools
Service creators can use standard tools such as
ASP (Active Server Page) or CGI (Common Gate-
way Interface) to generate content dynamically.
Services can be created once and then made
accessible on a broad range of wireless networks.
Maintain customer base
Existing services can be adapted to WAP. The nec-
essary binary encoding is handled by a WAP Gate-
way, allowing HTML-based services to be viewed
on the WAP browser of the Z600. An XHTML page
can be viewed in both the WAP browser and in any
standard Web (HTML) browser.
