3. Auto makers started installing wireless links in the mid-1990s, using
proprietary methods until the Wi-Fi international wireless LAN standard
appeared in 2001.
Wireless LANs as a mission critical infrastructure for its manufacturing
operations.
They initially use the massive in-plant wireless LAN infrastructure to
track materials and replenish parts at stations on its assembly lines.
They support wide range of application, which include access to
computer-aided design drawings and plant configuration information.
SUMMARY

4. It provides you with agility and flexibility that did not exist before.
GM has already equipped 75 to 100 forklift trucks with wireless
terminals in each plant.
When workers need to replenish parts for their station, they press a
button using the wireless.
They are also concerned with the network security.
Their biggest strategic weapon may be its involvement with standards
bodies and vendors to see that standardized security methods are
quickly incorporated into wireless gear.

5. 1) What is the business value of wireless
LANs to GM ?
There are several advantages to GM by adopting the
wireless LANs. It helps GM in reducing costs and also
helps to recoup its investment quickly .
Some of the advantages of wireless LANs to GM :
 Wireless LANs helps in tracking materials replenish
parts at stations on its assembly line.
QUESTIONS & ANSWERS

6.  It can also support wide range of other applications,
which includes access to computer-aided design
drawings and plant configuration information, which
can also be called “virtual factory” database.
 It also bring change in ability to send and receive
information to and from workers and system in
manufacturing .
 GM faced real problem with locating parts, but with
wireless LAN facility the parts can be located easily
with wireless LAN based material management system
which helps in reducing manufacturing costs.

7.  Wireless LAN helps GM workers who are in need to
replenish parts, can press a button on wireless
pendent at their workstation, the request is displayed
on a screen in forklift, showing location of worker and
materials required. This helps in minimizing the time
and manufacturing work can be done efficiently.

8. 2) What is the security vulnerabilities of
wireless LANs? Is GM taking
appropriate security measures? why
or why not?
The security vulnerabilities of wireless LANs is
hackers. GM is concerned about hackers, who can
hack systems through wireless transmission.
GM has adopted some approaches to overcome this
problem. GM segments its network with firewalls
and virtual private networks and they do detailed
site survey that look at all radio interference
sources. It also relies on good security software.

9. 3) What are some other possible business
applications of wireless LANs?
Evaluate the benefits and challenges
of one of them to a large or small
business.
some other possible business applications of
wireless LANs are :
 Wireless LANs can also be used in corporate offices
and business firms.
 Automatic request of materials.
 Some companies are launching wireless LANs
accessible mobile phones and other hand held devices
like PDAs etc..
 Scalability.

10. Benefits
1. It is faster and less expensive than other common
wire based LAN technologies.
2. The Wi-Fi or LANs enable laptop or PCs can connect
easily to internet and other networks.
3. It helps to minimize the wiring cost in office which
is very difficult and costly task.
4. It helps in eliminating the mistakes and damages of
repairing wires.

11. Challenges :
The main challenges of wireless LANs is from hackers.
They can hack into systems through wireless
transmission.
But this problem can be solved through security systems,
by relaying on good security software.
The installation charges of wireless LANs is costly and it
is
difficult to implement and maintain the same.

12. The use of wireless LANs is growing rapidly as
new high speed technologies are implemented,
which is used in increasing number of
business, public and home environment.
