WAP & WML

Notes limited to a maximum of 1400 bytes. This means that applications need to be specifically
designed to be very code efficient by using templates and variables and keeping information
on the server and using the cache on the phone. WML byte code converting (WMLC)
defines a (maybe inefficient) compression technique by string tables. With this technique
duplicate strings in the WMLC bytecode are avoided. This reduces the size of the data to
transfer to the mobile client. The WSP SDU size of 1400 bytes is a default value. An
increased size may be negotiated by a mobile client within the WSP capabilities.

Notes The WAP transport layer (WTP) is able to handle greater SDU sizes than 1400 too,
by using SAR (Segmentation and Reassembly).

10.1.2 Applications for WAP

The Wireless Application Protocol (WAP) is being used to develop enhanced forms of existing
applications and new versions of today’s applications.
The WAP will allow customers to easily reply to incoming information on the phone by allowing
new menus to access mobile services.
Early applications are modification of existing applications such as information, along with
applications such as mobile commerce, mobile banking and mobile games.

Mobile Commerce

Mobile commerce applications involve using a mobile phone to carry out financial transactions.
This usually means making a payment for goods or transferring funds electronically. Transferring
money between accounts and paying for purchases are electronic commerce applications.

There are several issues relating to the development of mobile commerce applications, such as
security, integration with the retail and banking hardware and systems, non-standardized mobile
infrastructure and competing e-commerce standards. Additionally, there is a lack of standards
relating to the mobile phone to network interface, the interfaces between host and mobile
platforms and between different mobile platforms. As such, the scalability of mobile commerce
is questionable. There are also questions about the appropriateness of using a mobile phone as
the interface to e-commerce applications. The MMI (Man Machine Interface) on mobile phones
is currently sub-optimal and difficult for mass-market users to manipulate. However, this area
of electronic commerce applications is expected to contribute to grow significantly in the future,
as mobile phone penetration delivers a critical mass of potential customers for such services.
It is expected that the mobile commerce will become just an extension of electronic commerce
on the Internet. There will not need to be any special applications developed for the mobile to
take into account screen, bandwidth and security limitations of the mobile device.

Did u know? What is Electronic Commerce?
E-commerce is a selling and transfer process requiring several institutes. It is systematic
and organized network for the exchange of goods between produces and consumers. The
Net aims to establish the interconnections between producers and consumers directly and
in this, the Internet embraces all those related activities which are indispensable for
maintaining a continuous, free and uninterrupted distribution and transfer of goods. The
Website or portals may be categorized into commercial and noncommercial.
