T68i
White Paper, April 2002

WAP services
The T68i has a WAP browser, supporting WAP
2.0(WML1.3).WAP2.0 optimizesusageof
higher bandwidths and packet-based
connections of wireless networks.
The typical WAP client is a small, portable device
connected to a wireless network. This includes
mobile phones, pagers, smart phones, PDAs and
other small devices. Of course, compared to
desktop and laptop computers, these devices
are limited by user interface, low memory and
low computing power.
The WAP browser in the T68i is compliant with
WAP2.0andincludesWTLSclass3aswellas
mechanisms for digital signatures. It supports
WML and XHTML. The WAP browser in the T68i
is also designed to access information such as
timetables, share prices, exchange rates,
Internet banking and other interactive services.
For more details, see “WAP browser technical
data” on page 58.
Using WAP in the T68i
The built-in WAP browser in the T68i gives the
user portable, fast and secure access to a wide
variety of services, including personalized
services, with new opportunities for business,
individuals and service providers:
Push services
Businesses and service providers can “push”
content or service indications to work groups
and/or customers. Examples of pushed content
would be mail alerts, messaging, news, stock
quotes, contacts, meeting requests, etc.
Support of XHTML
The WAP browser supports the markup
languages of WAP 2.0 – XHTML Mobile and
XHTML Basic. These two subsets of the Web
standard XHTML are supported by all major Web
browsers. An XHTML page can be viewed in
both the WAP browser and in any standard Web
browser. All of the basic XHTML features are
supported, including text, images, links,
checkboxes, radio buttons, text areas, headings,
horizontal rules and lists.
Support for cookies
This version of WAP has support for cookies
(client based), an application used by Web 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).
Sending bookmarks
WAP 2.0 enables the sending of bookmarks via
infrared and Bluetooth wireless technology (in
the vBookmark format) 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
manually. WAP settings may also be customized
by the operator. For more information, see “WAP
Operator technical data” on page 59.
Adapt to phone type
The User Agent Profile function allows WAP
content to be automatically optimized for the
T68i, ensuring the intended user experience.
Several bearer types
The T68i accesses WAP over a standard GSM
Data connection as well as over a GPRS
connection (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
CreatingaWAPserviceisnoharderthan
creating an Internet/intranet service, as WML and
WMLScript 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
Gateway 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
necessary binary encoding is handled by a WAP
Gateway, allowing HTML-based services to be
