Mobile computing faces issues such as insufficient bandwidth, security concerns, power consumption, transmission interference, and potential health hazards. Solutions include compression to reduce data transmission size, caching frequently accessed data, switching between cellular and satellite modes depending on location, and battery/chip redesigns to improve power efficiency. Researchers also recommend limiting phone use and choosing lower radiation cell phones to reduce potential health risks.

4. Introduction
The name MOBILE is derived from
M the need for mobility
O the need to improve operations
B the need to break business barriers
I the need to improve information quality
L the need to decrease transaction lag
E the need to improve efficiency

5. DEFINITION
Mobile computing is the discipline for creating an
information management platform, which is free from
spatial and temporal constraints.

6. Insufficient Bandwidth:
a) Mobile Internet access is generally slower than direct
cable connections, using technologies such as GPRS
and EDGE, and more recently 3G networks.
b) Higher speed wireless LANs are inexpensive but have
very limited range.

7. Security Standards:
a) Security is a major concern while concerning the mobile
computing standards on the fleet.
b) One can easily attack the VPN (Virtual Private Network)
through a huge number of networks interconnected
through the line.

8. Power consumption:
a)When a power outlet or portable generator is not
available, mobile computers must rely entirely on battery
power.
b)Mobile computing should also look into Greener IT in
such a way that it saves the power or increases the battery
life.

9. Transmission interferences:
a)Weather, terrain, and the range from the nearest signal point
can all interfere with signal reception.
b)Reception in tunnels, some buildings, and rural areas is often
poor.

10. Potential health hazards:
a)People who use mobile devices while driving are often
distracted from driving are thus assumed more likely to be
involved in traffic accidents.

11. Potential health hazards: (Cont.)
b)There are allegations that cell phone signals may cause
health problems.

12. Human interface with device:
Screens and keyboards tend to be small, which may make them
hard to use.

13. Security Issues:
Confidentiality:
Preventing unauthorized users from gaining access to critical
information of any particular user.

14. Security Issues:
Integrity:
Ensures unauthorized modification, destruction or creation of
information cannot take place.

15. Security Issues:
Availability:
Ensuring authorized users getting the access they require.

16. Security Issues:
Legitimate:
Ensuring that only authorized users have access to services.

17. Security Issues:
Accountability:
Ensuring that the users are held responsible for their security
related activities by arranging the user and his/her activities are
linked if and when necessary

19. Bandwidth:
Logging - bulk operations against short requests.
Compression – for data before transmission.
Lazy write back and file pre-fetching - data to be
written may undergo further modifications.
Caching - data can help improve query response time.

20. Location Intelligence:
Switching from infrared mode to radio mode as it
moves from indoors to outdoors.
Switching from cellular mode of operation to
satellite mode as the computer moves from urban and
rural areas.
Service connections must be dynamically transferred
to the nearest server.

21. Power Consumption:
Batteries should be ideally as light as possible also
capable of longer operation times.
Chips can be redesigned to operate at lower voltages.

22. Potential health hazards
Research and buy the cell phones with lowest radiation
levels.
Limit your phone calls.
Avoid placing cell phone on ear while call is connecting.
Use the chord phone or landline phone.
Turn your phone off at night.
