White Paper T290i/T290c

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 pos- sibility 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-com- merce 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 T290i/T290c supports CSS, and with its colour display, user presentation is further enhanced.

Easy to create WAP pages

Creating a WAP service is no harder than creating an Internet/intranet service, since the markup lan- guages (WML, WMLScript, XHTML Mobile Profile, and XHTML Basic) are based on well-known Inter- net languages such as HTML, XHTML, and JavaS- cript.

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.

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 T290i/T290c. An XHTML page can be viewed in both the WAP browser and in any standard Web browser.

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. For more information, see “WAP operator technical data” on page 55.

Adapt to phone type

The User Agent Profile function allows WAP con- tent to be automatically optimized for the T290i/ T290c capabilities, ensuring the intended user experience.

Several bearer types

The T290i/T290c accesses WAP over a standard GSM Data connection as well as over a GPRS con- nection (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.

Improve productivity

A business can use a WAP gateway to provide a secure connection to its corporate network, improving internal communication flow by making information available to mobile as well as office users.

The WAP profiles

A WAP profile holds network settings and user identification, allowing the user to switch easily between corporate services and WAP services on the Internet, simply by switching WAP profile.

The T290i/T290c has dynamic WAP profile han- dling, which means that the user can add, edit and delete WAP profiles. The T290i/T290c has a maxi- mum of 5 WAP profiles.

During WAP browsing, the options button on the T290i/T290c gives the user immediate access to a dynamic option menu for WAP services, similar to a right mouse click in PC programs.
