Sample text
Windows is covered in Chapter 4. Chapter 5 focuses on using Linux. Mac OSX and the comprehensive suite of penetration testing tools available on it are covered in Chapter 6. One of the easiest ways to get Linux tools running quickly and correctly is by using a bootable CD distro such as Auditor. Chapter 7 details how to use this type of platform. Once a WarDrive has been accomplished, you need to map out your WarDrives. Chapter 8 delves into mapping options. One of the most effective ways to compromise a wireless network is by using a Man-in-the-Middle (MITM) attack; Chapter 9 tells you how to do this.
W h e n a signal is transferring between being an R F signal in space and an AC signal on the wire, the transfer is more efficient when the antenna's physical size is a multiple of or a fraction of the wavelength. This is because of resonance, meaning that if the wavelength matches the physical size of the antenna, the antenna will oscillate easier at the frequency of the signal. This makes changing the type of signal more efficient. Electrical inefficiencies in a signal transfer to or from the air can result in less usable distance (known as a range) that the antenna can reach.
They are usually used to provide specific regional coverage for broadcast areas of Wireless Internet Service Providers (WISP) or similar applications Directional Antenna Types The following photographs show a number of directional antennas, which are representative of the various directional types. 10 shows a grid type directional antenna. Mainly used in Point-To-Point communications, these antennas are used where the antennas on either end of a link are fixed on masts or towers and only communicate with each other.
