Lesson Plan
Course Title: Business Information Management I
Session Title: Wireless Networks
Performance Objective:
After completing this lesson, students will understand how wireless networks are set up and the
standards that are following in the wireless technology.
Specific Objectives:
 Identify three major types of network cabling and of wireless network technologies.

Decide what kinds of cabling and connections are appropriate for particular network
environments.
Terms:
 Local Area Network – a wireless LAN is simply a network linking two or more computers
without wires (cables).
 Mobile Computing – is the use of portable computing devices (such as laptop and handheld
computers) in conjunction with mobile communications technologies to enable users to
access the Internet and data on their home or work computers from anywhere in the world.
 Line-of-sight Networks – transmits only if the transmitter and receiver have a clear line of
sight between them.
 Broadband Optical Telepoint Network – is capable of handling high quality multimedia
requirements that can match those provided by a cabled network.
 Narrow-band Radio – the nominal 3- kHz bandwidth allocated for single channel radio that
provides a transmission path for analog and quasi-analog signals.
 Single-frequency Radio – Any change in the frequency of a radio transmitter or oscillator
 Federal Communications Commission (FCC) – regulates interstate and international
communications by radio, television, wire, satellite and cable in all 50 states, the District of
Columbia and U.S. territories.

 130.114 (c) (5) (B&D – improve touch-system skills using the keyboard and keypad to input
data and demonstrate writing techniques generating ideas and gathering information relevant
to the topic and purpose, maintaining accurate records of outside sources
English:
 110.31.b.15.B – write procedural or work-related documents (e.g., instructions, e-mails,
correspondence, memos, project plans)
 110.31.b.19 – students are expected to spell correctly, including using various resources to
determine and check correct spellings.
 110.31.b.22.B&C – evaluate the relevance of information to the topic and determine the

reliability, validity, and accuracy of sources and implement changes as the need occurs and
is identified
Teacher Preparation:
 Teacher will review the terms in the outline, power point and handouts to become familiar
with lesson.
 Teacher should locate and evaluate various resources and websites before the lesson.
 Teacher will have assignments and website information ready to distribute to students.

Introduction
Introduction (LSI Quadrant I):
Have students break up into groups. Assign each group to research the four wireless LAN
Technologies.

can be linked by the
same method as your
cordless telephone
operates in your home by transmitting the
signal through air. In
many offices today,
computers
communicate with each
other and with printers
and other devices by
sending information
along wires.
When describing an
extended wireless
network, the best way
to connect with
students is compare to
wireless cell phones
and the ability to travel
and the use of several
towers. Also, you may
want to mention
dropped calls when an
extended network is not
available.
Mobile Computing, also
know as Wireless
networking, is the use
of portable computing
devices (such as laptop
and handheld
computers) in
conjunction with mobile
communications
technologies to enable
users to access the
Internet and data on
their home or work
computers from
anywhere in the world.

Guided Practice (LSI Quadrant III):
Have students break up into groups. Ask students to discuss why wireless networks are
becoming more popular, particularly in old buildings and educational institutions? After the
discussion ask student to justify their responses in writing.
Independent Practice (LSI Quadrant III):
Give students a network design scenario including number of workstations, servers and printers.
Provide a diagram of a local community building with approximate locations of the network
devices. Have the students spec out materials needed for the physical layer design, such as,
cabling and connectors. They should include cost of materials in their final design plan, which will
require other software applications such as Microsoft Word and Excel. (Encourage the use of
templates).
Summary
Review (LSI Quadrants I):
1. Name the four wireless LAN technologies used for transmitting and receiving data.
Answer: infrared, laser, narrow-band, spread-spectrum radio
2. Which wireless standard has become the most prevalent and has been in use the longest?
Answer: 802.11b
Evaluation
Formal Assessment (LSI Quadrant III, IV):
Give students a network design scenario including number of workstations, servers and printers.
Provide a diagram of a building with approximate locations of the network devices. Have the
students specify materials needed for the physical layer design, such as, cabling and connectors.
They should include cost of materials in their final design plan.
Extension
Enrichment/Extension:
Invite the network administrator from a local company that uses wireless technologies. Ask them
to explain the type of LAN technology implemented at their company.
