WAP services
The T68i has a WAP browser,suppor ting WAP
2.0(WML1.3).WAP2.0 optimizesusageof
higher bandwidths and packet-based
connectionsof wireless networks.
Thetypical WAP client is a small, portable device
connectedto a wirelessnetwork. This includes
mobilephones, pagers, smart phones, PDAs and
other small devices. Of course, compared to
desktop andlaptop computers, these devices
are limitedby user interface, low memory and
low computing power.
The WAP browserin the T6 8iis compliant with
WAP2.0andincludesWTLSclass3aswellas
mechanisms for digital signatures. It suppo rts
WML and XHTML. The WAP browser in the T68i
is also designedto access information such as
timetables,share prices, exchange rates,
Internet banking and other interactive services.
For moredetails, see “WAP browser technical
data” on page 58.

Using WAP in the T68i

The built-inWAP browser in the T68i gives the
user portable,fast and secure access to a wide
variety of services, including personal ized
services,with new opportunities for business,
individuals and service providers:
Push services
Businessesand service providers can “push”
contentor service indicationsto 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 WAPb rowsersupports the markup
languages of WAP 2.0 – XHTML Mobile and
XHTML Basic. These two subsets of the Web
standardXHTML are supported by all major Web
browsers.An XHTML page can be viewed in
both the WAPbrowser 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 rulesand lists.
Support for cookies
This version ofWAP has support for cookies
(clientbased), an application used by Web sites
to storesite-specific information in the browser
betweenvisits to the site. Cookies give the site
owner a possibilityto see when a person has
visited their site. They also save the user from
having to enterthe same information (e.g. the
passwordor user ID) more than once. Cookies
are oftenused by e-commerce sites (shopping
carts and wish lists).
Sending bookmarks
WAP2.0 enables the sending of bookmarks via
infraredand Bluetooth wireless tech nology (in
the vBookmark format)as well as via SMS.
Provide settings
UsingSMS messages, configuration settings can
be sent over the air,OTA, so that the user does
not need to configurethe WAP accesssettings
manually.WAP settings may also be customized
by theoperator. For more information, see “WAP
Operator technicaldata” on page 59.
Adapt to phone type
The User Agent Profilefunction allows WAP
content to be automaticallyoptimized for the
T68i, ensuring the intended user experience.
Several bearertypes
The T68i accessesWAP over a standard GSM
Data connection as well as over a GPRS
connection(network-dependent services.)
Bandwidth efficiency
Unliketraditional Internet services, WAP services
are relayedto wireless devices as binary
encoded data, maximizingbandwidth efficiency.
A GPRS connectionfurther increases efficiency.
Easy create forWAP
CreatingaWAPserviceisnoharderthan
creatingan Internet/intranet service, as WML and
WMLScript arebased on well-known Internet
languagessuch as HTML and JavaScript.
Using standardtools
Service creatorscan use standard tools such as
ASP (Active Server Page) or CGI (Co mmon
Gateway Interface)to generate content
dynamically. Services can be created once and
then made accessibleon a broad range of
wirelessnetworks.
Maintaincustomer base
Existingservices can be adapted to WAP.The
necessarybinary encoding is handled by a WAP
Gateway,allowing HTML-based services to be
