Definition of Mobile and Wireless
• Mobile
– The ability to be on the move.
• Wireless
– The transmission of voice or
data over radio waves

4. Mobile computing and wireless
communication just a few years ago

5. Why to choose mobile?
 Business Benefits
 Increased employee productivity
 Faster response time
 Improved competitive advantage
 Reducing costs
 End-user Benefits

6. Mobile/Wireless Application Options
 Wireless Internet (online only)
 Online access to Web content
 Typically used for consumer applications
 Limited user interface and capabilities
 Smart Client
 Allows for offline access to important data
 Works best in ‘occasionally connected’ environment
 Messaging
 Store and forward delivery of data
 Text messaging is very popular, multimedia the next thing
 Can be used on its own, or in addition to other architectures

7. Shopping in the future

8. Services on the Web
8
 Web Services provide data and services to other
applications.
 Thee applications access Web Services via standard
Web Formats (HTTP, HTML, XML, and SOAP), with
no need to know how the Web Service itself is
implemented.
 Web services provide a standard means of
interoperating between different software applications,
running on a variety of platforms and/or frameworks.

10. Web services building block
• SOAP
• WSDl
• UDDI

11. Wireless Environment
 Wireless Operators and Service Providers
 Device Manufacturers
 Hardware vendors
 Software infrastructure Providers
 Independent Software Vendors
 System Integrators

12. Variability of the mobile
environment
Mobile device capability
Mobility
Connectivity

13. M-Commerce

 Processors type and speed
 Screen
 Size and colour
 Indoor/Outdoor
 OS
 Software support
 Expansion capabilities
 Built-in functionality

17. Wireless Networks
Satellite

18. WPAN Applications
 For business applications, anytime you would
use a cradle for a network connection, a WPAN
can work
 SQL Anywhere Studio can synchronize data wireless
over WPAN networks without modifying the application!
 In some confined environments, Bluetooth can
be used as a local area network
 As cable replacement for peripherals
 Future uses include many embedded devices
such as sensors, interactive toys, smart badges,
and home automation

19. WLAN Configurations
Peer to Peer Wireless LAN

20. Wide Area Networks
 Main Characteristics:
 Long-range communication (national coverage)
 Data rates from 9.6 kbps to 2 Mbps
 WWANs were initially implemented for voice
communication, but data communication is a key
focus with the latest offerings

21. WWAN Applications
 WWANs are still primarily used for voice
communications
 Adoption of data services has been strong for
text messaging, and now, multimedia
messaging
 Consumer uses include wireless Internet
access, whereas corporate usage is often
focused on smart client synchronization and
PIM and email access
 The widespread deployment of 3G networks
has been hindered by Wi-Fi hotspots

22. Network issues
 Increased bandwidth
 Always-on capability
 Lower costs
 Enhanced services
 roaming

23. Location-based services

24. CONCLUSION
24
 So, I conclude by saying that by the usage of web
services on mobile devices any individual can
improve his performance and make efficient use
of resources .
