7. The Attributes of M-computing and M-commerce
 Mobility implies portability: user can carry a
mobile device with them
 Broad reach: people can be reached at any
time.
These two characteristics create five value-added
attributes that break the barriers of
geography and time, ubiquity, convenience,
instant connectivity, personalization , and
localization of products and services.

8. The Attributes of M-computing cont…
 Ubiquity: fill the need for real- time information and
communication , independent of the user’s location.
 Convenience and instant connectivity: easy and
fast access the web, intranets, and other mobile
devices without booting up a PC or placing a call via
a modem.
 Customization: Information can be customized and
sent to individual consumers as an SMS.
 Localization: knowing where a user is physically at
any particular moment is key to offering relevant
products and services.

15. 6.6 Mobile Intrabusiness Applications
 Support of mobile workers with wearable
devices such as: Screen, Camera, Touch-panel
display, Keyboard, and Speech
Translator
 Job Dispatch
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 6 15

16. Intrabusiness Workflow Application
Before Wireless With Wireless
Work orders are manually assigned by
multiple supervisors and dispatchers
Work orders are automatically assigned and
routed within minutes for maximum efficiency..
Field service technician commute to
dispatch center to pick up paper work
orders
Home-based filed services technicians receive
first work order via mobile terminal and proceed
directly to first assignment.
Manual record keeping of time, work
completed, and billing information.
Automated productivity tracking, record keeping
and building updates
Field service technicians call for new
assignments and often wait because of
radio traffic or unavailable dispatcher.
Electronic transmittal of additional work orders
with no waiting time
Completed work orders are dropped off at
the dispatch center at the end of the day
for manual entry into the billing tracking
system. Uncompleted orders are manually
distributed to available technicians.
Overtime changes often result.
Technicians close completed work orders from the
mobile terminals as they are completed . At the
end of shift. The technicians sign off and go
home.

17. 6.7 Mobile Enterprise and
Supply Chain Applications
 Support of customers and business partners
 Supply chain applications
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 6 17

18. 6.8 Location-Based Commerce
 Location based commerce (l. commerce):M-commerce
transactions targeted to
individuals in specific locations, at specific
times.
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 6 18

19. L-commerce Technologies
Providing location- based services requires the following
technologies.
Position- determining equipment (PDE): This equipment
identifies the location of the mobile device.
Mobile positioning center (MPC): The MPC is a server that
manages the location information sent from the PDE
Location-based technology: The technology consist of groups
of servers that combine the position information with
geographic- and location- specific content to provide an l-commerce
service
Geographic content: Geographic content consists of streets,
road map, addresses, routes, landmarks, land usage , Zip
codes and the like.
Location-specific content: Location-specific content is used in
conjunction with the geographic content to provide he
location of particular services.

System that integrate GSP data onto
digitized map displays.
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 6 20

21. Telemetry Applications
 Telemetry is the science that measures
physical remoteness by means of wireless

27. Technical and other limitations of
mobile computing
Limitation Description
Insufficient bandwidth Sufficient bandwidth is necessary for widespread use and it must be inexpensive. It will take a
few years until 3G is in many places .Wi-FI solves some of the problem.
Security standards Universal standards were not available in 2003 . It may take 3 or more years to have them .
Power consumption Batteries with long life are needed for mobile computing . Color screens and Wi-FI consume
more electricity , but new chips are solving some of the power-consumption problems.
Transmission interferences Weather and terrain problems as well as distance-limited connection exist with some
technologies . Reception in tunnel and some building is poor
GPS accuracy GSP may be accurate in a city with tall buildings
WAP limitations According to mofileinfo.com, in 2002 there were only about 50,000 WAP sites (compared to
millions of Web sites) . WAP still is a cumbersome process to work with.
Potential health hazards
Potential health damage from cellular radio frequency emission is not known yet . However,
more car accidents are related to drivers who were talking (some places bar the use of cell
phones while you drive ) also, cell phones may interfere with sensitive medical devices.
Legal issues Potential legal issues against manufactures of cell phones and against service provides exist,
due to the potential health problems
Human interface with device Screen and keyboards are too small and uncomfortable and tedious for many people to use
Complexity Too many optional add-ons are available (e.g., battery chargers, external keyboards,
headset, microphone, cradles) . Storing and using the optional add-ons can be a problem
