WAP & WML

Notes The companies would also explore markets both in India and neighbouring countries.
WorldSpace already provides satellite radio offerings in select cities in the country.
WorldSpace India has a range of 40 radio stations across genres - from jazz to classical, and
old Hindi film music to rock.
Its Indian programming includes two Indian classical stations as well as regional stations.
Over the next two years, WorldSpace will invest about $150 million in technology
development and marketing in the Indian market, Mr Samara said.
The company has already invested around $200 million in and for the development of the
Indian market.

On its part, WML has been serving the electronic media for the last 25 years.
Over the years, it has supplied products to Doordarshan kendras and All India Radio
stations. It has also pioneered the manufacture of studio equipment and community radio
systems in the country.
According to a senior official of WML, the MoU with WorldSpace is the first of its kind in
India. It envisages the development of hybrid technology-based digital audio broadcasting
systems.
The scope of such digital audio broadcasting systems based on the coded orthogonal
frequency division multiplexing technology is huge not just in India but in developed,
mature markets, he added.

5.6 Summary

 WML is Wireless Markup Language which creates web pages for the handheld devices.
The structure, formatting, and syntax of WML are familiar with HTML and XML.

 WML is a direct descendent of Handheld Device Markup Language (HDML). WML,
however, has been optimized for the constraint wireless device. As a result, there is a
prominent difference between HTML and WML.

 WML requires a micro browser to interpret the various commands necessary to render a
document, or “deck”. These browsers are usually embedded in the mobile device.

 WML is mostly about text. Tags that would slow down the communication with handheld
devices are not a part of the WML standard. The use of tables and images is strongly
restricted. Since WML is an XML application, all tags are case sensitive, and all tags must
be properly closed.
 WAP Gateway Server performs the critical bridge functions of communicating with the
mobiles device and translating sent-received data to and from Web Servers.
 WAP Client means the end user for wireless services. The user platform includes all
necessary applications.

 WAP Gateway manages two-way communication between a mobile device and the wired
Internet. Translates Web Server output (HTTP) to wireless application protocols (WAP) to
send to mobile service and vice versa.
 Web Server means standard web server, including Web Proxy.
