The document discusses how to set up a WiFi network for mobile devices in an office. Some key points include: 1. A WiFi network allows employees to easily share internet access and files from any device without wires. 2. Setting up the network requires installing a wireless router and ensuring all devices have a wireless adapter. Access points should be placed strategically to provide full coverage. 3. Network security is important, so the router should use a strong encryption standard like WEP or VPN to authenticate devices and protect data on the network.

3. Networking is an essential productivity tool for today's
mobile workforce. With wireless networking, employees
can stay connected with their company's information
resources virtually anytime, anywhere.

4. The concept of using mobile devices at work is gaining
popularity among businesses in today’s work environment.
Therefore, the popularity of wireless LANs is a testament
primarily to their convenience, cost efficiency, and ease of
integration with other networks and network components
(“Wireless Networking,” 2011).

5. What is WiFi?
WiFi is an abbriviation for
Wireless Fidelity
WiFi allows users to access high speed
internet and network connections without
the use of wires and cables. Furthermore,
a wireless network can sometimes be
cheaper and easier to setup than a wired
network.

802.11
Is the common
wireless network
standard for PC
network standards
based on the
Institute of Electrical
and Electronics
Engineers (IEEE) .

Wireless
networks use radio
waves to transmit
signals. They
transmit at
frequencies of 2.4
GHz or 5 GHz.
Radio
The signal
Signals are
transmitted through a
computer’s wireless
adapter.
Is received by a
wireless router which
then decodes it.

8. Requirements for setting up a wireless network:
A router is used for a wireless local area network (WLAN) to connect
computers to a shared internet connection.
A wireless adapter is a piece of hardware that comes previously
installed in most computers today. It can also be installed in devices
that will be using the wireless network.
A wireless switch is used to connect multiple computers for
communication on a wireless LAN. It is used to connect a wireless network
of three or more computers or wireless electronics (“What equipment is”,
2012).
A repeater is a wireless signal amplifier that extends the distance of a
wireless LAN. This makes it much easier to expand a network for a larger area
later on.

9. Access Point Distance
Access Points
• First it needs to be determined how
many users there will be on average. This
will determine how many access points
there need to be.
02/28/14
• Then it will need to be decided where in
the office most employees will use the
network wirelessly. This will determine
where the access points will be put.

10. Network Capacity - My Office
Employees
Devices
Office Space
10 people
Up to 40
2,000 sq ft
There are 10 employees
that work in my office.
However, this fluctuates
because everyone is not
always there at the same
time. Also, more people
can be in the office when
they are in training.
If everyone in the office
had a laptop and mobile
phone, and every
employee was in the office
at the same time with 10
trainees, there would be 40
devices on the network
simultaneously.
There are approximately
2000 square feet of office
space in the office. This
affects where the access
points will go.
I work for the Brotherhood of Locomotive Engineers and Trainmen (BLET) as an
employee trainer. Our office location is small and I can see how having a mobile network
would greatly benefit different aspects of our jobs in many ways.

12. Network Security
Security
Security is an important issue
when setting up a wireless
network. In short, it keeps you
safe no matter where you go.
Thus, there are two main types
of wireless security, encryption
and authentication standards.

13. Network Security
WEP
VPN
Wired Equivalency Policy (WEP) is the
standard encryption for 802.11 WLANs.
Virtual Private Networks are also
considered strong authentication and
encryption mechanisms between the
access points and the WLAN.

14. Network Security
Every network needs a policy for
usage and security, and WLANs
are no different. While policies will
vary based on individual security
and management requirements of
each WLAN, a thorough policy and enforcement of the policy can protect an network from
unnecessary security breaches
and performance degradation
(“The Mobility and”, 2004).
A policy can state that stations
connect at higher speeds to
ensure that intruders nearby
cannot connect at speeds of
5.5Mbit/sec. and 11Mbit/sec or
only become available during
certain hours.
Security policies are useless without enforcement.
Security mangers employ intrusion-detection systems (IDS) and protection to ensure that
all components of WLANs are secure and protected from wireless threats and attacks.
