m-Commerce describes the phenomenon of using wireless mobile devices such as

digital phones and PDAs to search the Internet, access data and information, and
conduct purchasing or business transactions. m-Commerce is fueled by the extreme
popularity of mobile devices such as laptop computers, cellular phones, PDAs
(personal digital assistants), and palm pilots.

Voice commerce (v-commerce) is gaining importance to support users who want to

use telephones and other voice-driven devices for conducting ecommerce.

Positional commerce (p-commerce) is becoming popular to provide support to

customers based on their geographic position

7. What are the services provided by mobile computing platforms?

Local platform services :that support the applications on the individual mobile
devices. These services consist of operating systems (e.g., Symbian OS) needed to
run the mobile devices,

ƒ Network transport services :that are responsible for shuffling the messages over,
in this case, wireless networks. These services, mostly handled by the Internet
technologies (TCP/IP, in particular)

ƒ Middleware services that interconnect mobile users, databases and applications

with each other.
8. Draw the Conceptual view of wireless web.

9.What are the functions of wireless-middle ware?

 Establishes connections between mobile clients and servers over wireless

networks and delivers messages over the connection.
 ƒ Transforms data from one format to another (e.g., one type of markup to
another).
 ƒ Detects the mobile device characteristics and optimizes the wireless data
output according to device attributes.
 ƒ Compresses data to minimize the amount of data being sent over a slow
cellular wireless link.
 ƒ Encrypts/decrypts data for security.
 ƒ Allows monitoring and troubleshooting of wireless devices and networks.

10. What are the main element of WAE?

The main elements of WAE are:

 ƒ A markup language called Wireless Markup Language (WML) that is

similar to XML but that has been optimized for wireless links and devices. A
scripting language (WMLScript) is also provided.
 ƒ Specification of a microbrowser in the wireless terminal. This is
analogous to the standard Web browser – it interprets WML and WMLScript
in the handset and controls presentation to the user.
 ƒ A framework, the Wireless Telephony Applications (WTA) specification,
to allow access to telephony services such as call control, messaging, etc.
from within the WMLScript applets.

12. what are the components of satellite systems.

 ƒ Transponder – electronics in the satellite that convert/amplify uplink
signals to downlink signals. There are typically 16 to 20 transponders per
satellite, each with 36-50 MHz BW (bandwidth).
