Internet 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 with new opportunities for business, individuals, and service
providers.
Using the Internet with J200
Push service
A useful feature for companies and service provid-
ers is to push content or service indications to work
groups or customers. This is used for notifications,
mail alerts, messaging, news, stock quotes, con-
tacts, meeting requests, games and the like.
Provide settings
Using text 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 can 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 intend,
regardless of client device type. The function User
Agent Profile is supported by the J200 to allow the
contents to be automatically optimized for the
phone.
Several bearer types
The J200 accesses WAP over a standard GSM
Data connection as well as over a GPRS connec-
tion (network-dependent services.)
Option key while browsing
During browsing, a press on the option key gives
the user immediate access to an option menu while
using WAP services, similar to right-clicking the
mouse in PC programs.
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.
Easy create for WAP
Creating a WAP service is no harder than creating
an intranet/Internet service today since WML and
WMLScript are based on well-known Internet tech-
nology. New market segments can be addressed
by launching innovative mobile Value Added Serv-
ices.
Using standard tools
It is possible for the service creator to use standard
tools like ASP or CGI to generate content dynami-
cally. You can utilize existing investments in data-
bases that are the basis of existing Internet
services. Create a service once and make it acces-
sible on a broad range of wireless networks.
Maintain customer base
You can adapt existing Internet services to WAP.
The actual binary encoding can be handled by the
WAP Gateway which makes it possible to create
WAP applications using the text-based language
WML and other tools. In fact, existing HTML-based
applications on the Internet can be viewed in the
WAP browser, if an automatic conversion is per-
formed in the WAP Gateway.
