Chapter 7 Wireless Encryption uses a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every device in the wireless network must have the same key. 7.8.4 Signal Problems Because wireless networks are radio networks, their signals are subject to limitations of distance, interference and absorption. Problems with distance occur when the two radios are too far apart. Problems with interference occur when other radio waves interrupt the data signal. Interference may come from other radio transmissions, such as military or air traffic control communications, or from machines that are coincidental emitters such as electric motors or microwaves. Problems with absorption occur when physical objects (such as thick walls) are between the two radios, muffling the signal. 7.8.5 BSS A Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS traffic blocking is disabled, wireless station A and B can access the wired network and communicate with each other. When IntraBSS traffic blocking is enabled, wireless station A and B can still access the wired network but cannot communicate with each other.
