Many types of encryption use 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.

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.

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 Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired 
network but cannot communicate with each other.
