TABLE OF CONTENTS This chapter focuses on how to perform a wireless test against a client, and examines some of the vulnerabilities related to wireless video. It also explores the different tools that can be used to perform these tests, and the type of information these tools provide.
When wireless technology was first released, it took the networking world by storm. Companies loved the freedom and power they had in their hands. However, this same technology was also being used in cordless phones, computer peripherals, handheld devices, home monitoring equipment, wireless video, and amateur television broadcasts.
Wireless video immediately became an application standard. It was inexpensive, didn t require running huge lengths of cable through a building, and easy to install; these facets also made it affordable to the mass market.
In this chapter, we examine primarily those systems that operate in the open 2.4 Gigahertz (GHz) frequency band. There are dozens, if not hundreds, of video solutions that work in this frequency range; however, some also work in other frequency ranges (e.g., 1.2 GHz and 900 MHz (discussed briefly). Some of the tools discussed in this chapter are also applicable to different frequencies. All of the video systems that we will look at operate on specific channels within the 2.4 GHz range.
The transmission format of video signals in the U.S. is different from the transmission format of video signals elsewhere in the world. The two most widely used formats are the National...
