WEP is an encryption scheme, based on the RC4 cipher, that is available on all 802.11a, b and g wireless products. WEP uses a set of bits called a key to scramble information in the data frames as it leaves the access point or client adapter and the scrambled message is then decrypted by the receiver. Both sides must have the same WEP key, which is usually a total of 64 or 128 bits long. A semirandom 24 bit number called an Initialization Vector (IV), is part of the key, so a 64 bit WEP key actually contains only 40 bits of strongencryption while a 128 bit key has 104. The IV is placed in encrypted frames header, and is transmitted in plain text.

Ubuntu based Live Cd For Wireless Hacking. This version updated and provides a graphical interface. There is a script to be installed on the PC hard drive or a virtual machine (VirtualPC is not supported). Wireless Hacking LiveCD 2010 integrates over 50 tools to work with the network scanners, sniffers, password crackers, and so on. Works almost with all systems.

A Complete Roadmap to Wireless Mesh Network Design Principles and Practices Using WiFi, WiMAX, and ZigBEE! Wireless Mesh Networking provides everything needed to create in-demand wireless mesh networks that provide wireless broadband access over wide areas. This resource presents a complete roadmap to the design and operation of wireless mesh networks, covering basic principles, key standards, and all aspects of network operation-from antenna technologies to software to energy management.

Data and models for better systems designAtmospheric gases, building materials, the weather … The propagation of wireless communications signals depends upon a whole range of factors, any or all of which can have a significant impact on the quality of a signal. Data generated by careful measurement of signals propagating under various environmental conditions are therefore fundamental to designing and building efficient, robust, and economical communication systems. This handbook presents models that describe that data and make predictions for conditions that will affect operational systems. The author-chair of the science panel for the ACTS propagation experiment-focuses on EM waves of 0.3 to 300 GHz propagating through the lower atmosphere.

The first of a two-volume set, this leading-edge book takes a practical approach to RF circuit design, offering a complete understanding of the fundamental concepts you need to know and use for your work in this industry. The book lays the ground work for efficient RF circuit design in a step-by-step approach, by defining important principles and parameters and progressively introducing critical analytical tools. It helps you distinguish between RF and low frequency circuits, and offers a detailed look at a typical RF system

A complete, practical guide to wireless network technologies and RF propagation methods, giving the engineer the knowledge and skills to implement high performance wireless networks.
