Chapter 2
Wireless Data Transmission
Lecture Notes
Overview
Chapter 2 explains various wireless data transmission techniques. Students will learn
how network data is represented using binary notation. Chapter 2 also lists and explains
the two types of wireless transmission. Finally, students will study the basic concepts
and techniques through which data can be transmitted by radio waves.
Objectives
•
Explain how network data is represented using binary notation
•
List and explain the two types of wireless transmission
•
Illustrate the basic concepts and techniques through which data can be transmitted by
radio waves

Additional Projects
1.
Write a method to convert a number in Base 10 to its representation in Base 2. Then,
write a method to convert a number in Base 2 to its representation in Base 10. Finally,
test your methods and convert the number 1024 in Base 10 to Base 2 and the number
1001111001 in Base 2 to Base 10. What are the results?
