White Paper T310/T312
17 January 2003
WAP services
The T310/T312 supports the WAP 1.2.1 browser
and protocol stack as well as the WAP 2.0 browser.
The T310/T312 has a WAP browser, supporting
WAP 2.0 (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 T310/T312 is compliant
with WAP 2.0 and includes WTLS class 3 as well as
mechanisms for digital signatures. It supports WML
and XHTML. The WAP browser in the T310/T312 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 59.
Using WAP in the T310/T312
The built-in WAP browser in the T310/T312 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, check boxes, 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 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 61.
Adapt to phone type
The User Agent Profile function allows WAP
content to be automatically optimized for the T310/
T312, ensuring the intended user experience.
Several bearer types
The T310/T312 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.
