Specifications

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 R520 is compliant with WAP June2000 (WAP 1.2.1) and 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 reser-

vation. 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.

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 R520 offers new opportuni-

ties 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

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

meeting requests, games etc.

Provide settings Using SMS message, conÞguration settings can be sent over the air,

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

tings manually.

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 ProÞle is supported by the R520 to allow the con-

tents to be automatically optimized for the phone.

Security They 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 Wireless

IdentiÞcation Module (WIM) are supported in the R520. The WIM is

used to store security related information.

Synchronize remotely The R520 can update the calendar and phone book with a remote cal-

endar on the Internet, over WAP. In this way, users can keep their cal-

endars up to date with corporate meeting planning wherever they are.

Several bearer types The R520 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.)

Options button During WAP browsing, the options button on the R520 gives the user

immediate access to a dynamic option menu when using WAP ser-

vices, similar to a mouse right-click in PC programs.

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

mobile devices, is the bandwidth efÞciency 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 efÞciently. See ÒUsing GPRS in

R520Ó on page 24.
