WAP services
The T226 supports WAP 1.2.1 browser and protocol
stack, as well as WAP 2.0 browser (WML 1.3). WAP
2.0 optimizes usage of 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 T226 is compliant with WAP
2.0 and WAP 1.2.1. It includes WTLS class 3 as well
as mechanisms for digital signatures. The T226
supports WML, XHTML, and iHTML. The WAP
browser in the T226 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 47.
Using WAP in the T226
The built-in WAP browser in the T226 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 Profile 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 SMS.
Cascading Style Sheets (CSS)
WAP 2.0 enables CSS. CSS allows developers to
specify the style of WAP page content such as font,
spacing, etc. The T226 supports CSS, and with its
color display, user presentation is further enhanced.
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 48.
Adapt to phone type
The User Agent Profile function allows WAP content
to be automatically optimized for the T226
capabilities, ensuring the intended user experience.
Several bearer types
The T226 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 to create WAP pages
Creating a WAP service is no harder than creating an
Internet/intranet service, since the markup languages
(WML, WMLScript, XHTML Mobile Profile, and
XHTML Basic) are based on well-known Internet
languages such as HTML, XHTML, 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
