Wireless Communications Paper Wireless communication involves the transmission of data from one point to another without the need to run cabling in-between. Although it seems relatively new to the end user today, it has surprisingly been around for longer than you may think dating back to the late 1800’s. The first wireless technology discovered was the Radio Frequency (RF signal). Thomas Edison and Nikola Tesla were two inventors that played a huge role in developing the RF technology we still

Wireless networks are vulnerable to the following specific security attacks: Attack Description Rogue access point A rogue access point is any unauthorized access point added to a network. Examples include: • An attacker or an employee with access to the wired network installs a wireless access point on a free port. The access port then provides a method for remotely accessing the network. • An attacker near a valid wireless access point installs an access point with the same (or similar) SSID

Introduction This lab will introduce you to wireless spectrum analysis and supports this week’s TCO. TCO 7: Given a situation requiring a wireless network solution, propose an appropriate design for a wireless network using radio frequency based methods. Background Wireless signals are invisible to the human eye. To see these signals, a tool such as a spectrum analyzer is required. In this lab, you will learn how to use a common spectrum analyzer, as you would in your career, to locate
