Department of BCA

2. HOW TO DEFINE???
 Mobile computing is a generic term describing one's
ability to use technology while moving, as opposed to
portable computers, which are only practical for use
while deployed in a stationary configuration.
 Many types of mobile computers have been introduced
since the 1990s, including the:
 Wearable computer
 Personal digital assistant /Enterprise digital assistant
 Smart phone
 Carputer
 UMPC
 Pocket PC

3. Why Mobile Computing ?
 People are mobile
 Devices are mobile

4. DIFFERNENT COMPUTING
DEVICES

5. Mobile Computing Devices

6. What is Mobility?
 A person who moves
• Between different geographical locations
• Between different networks
• Between different communication devices
• Between different applications
 A device that moves
• Between different geographical locations
• Between different networks

7. Wireless Networks

8. Mobile Applications
 Vehicles
• transmission of news, road condition etc
• ad-hoc network with near vehicles to prevent
accidents
 Emergencies
• early transmission of patient data to hospital
• ad-hoc network in case of earthquakes
• military

9. Mobile Applications
 Traveling salesmen
• direct access to central customer files
• consistent databases for all agents
• mobile office
 Web access
• outdoor Internet access
• intelligent travel guide with up-to-date
location dependent information

10. Mobile Applications
 Location aware services
• find services in the local environment, e.g. printer
 Information services
• push: e.g., stock quotes
• pull: e.g., nearest cash ATM
 Disconnected operations
• mobile agents, e.g., shopping
 Entertainment

11. Mobile applications in the
Industry
 Wireless access: (phone.com) openwave
 Alerting services: myalert.com
 Location services: (airflash) webraska.com
 Intranet applications: (imedeon)
viryanet.com
 Banking services: macalla.com
 Mobile agents: tryllian.com

12. Limitations of mobile computing
 Insufficient bandwidth
 Security standards
 Power consumption
 Transmission Interferences
 Potential Health Hazards
 Human Interface with devices

13. QUALITY OF DATA
 Mobile computing enables immediate
validation of the data
 It reduces the transcription error for
survey like applications
 Using networking, information can be
made available in near real-time
 Very fast turn around time from data
collection to analysis and reporting. This
can translate into significant cost saving.
