WAP SERVICES

The typical WAP client is a small, portable device which is connected to a wireless network. This includes mobile phones, pagers, smart phones, PDAs and other small devices. In these devices, you have a limited user interface, low memory and computing power compared to desktop and laptop computers.

The WAP browser in the T39 is compliant with WAP June2000 (WAP 1.2.1) includes WTLS class 3 and mechanisms for digital signatures. It is designed for WML and cannot read ordinary HTML pages, but it is suitable for interaction with customer services, e.g. ticket reservation. It is also handy when you want to access text-based information, such as timetables, share prices and exchange rates and internet banking and other interactive services.

Using WAP In The T39

The built-in WAP browser gives the user portable, fast and secure access to a wide variety of services, with the possibility of personalized services. WAP in the T39 offers new opportunities to companies and service providers:

Push service

A useful feature for companies and service providers to push contents

 

or service indications to work groups or customers. This is used for

 

notifications, mail alerts, messaging, news, stock quotes, contacts,

 

meeting requests, games etc.

Provide settings

Using SMS message, configuration settings can be sent over the air,

 

OTA, so that the user does not need to configure the WAP access set-

 

tings manually. WAP settings may also be customized by the operator.

Adapt to phone type

When creating a WAP service, you want to make sure that the user

 

experience is what you intended, regardless of client device type. The

 

function User Agent Profile is supported by the T39 to allow the con-

 

tents to be automatically optimized for the phone.

Security

Service providers can offer commercial and business critical services

 

with high security to mobile users, compliant with Wireless Transport

 

Layer Security (WTLS) class 1, 2 and 3. Digital signatures and Wire-

 

less Identification Module (WIM) are supported in the T39. The WIM

 

is used to store security related information.

Several bearer types

The T39 accesses WAP over a standard GSM Data connection as well

 

as over a GPRS connection. SMS is available as bearer type also. (Net-

 

work-dependent services.)

Bandwidth efficiency

One of the key advantages WAP has over text-based HTML pages on

 

mobile devices, is the bandwidth efficiency for communication. This is

 

due partly to the fact that the WAP application is communicated to the

 

wireless devices in the form of binary encoded data. Over a GPRS con-

 

nection, bandwidth is used even more efficiently. See “Using GPRS In

 

The T39” on page 11.
