The Extended Service Set ID (ESSID) is the name of the network you want to access. It 

is used to identify different wireless networks.

  

 

 

Factors of interference: 

  Obstacles: walls, ceilings, furniture… etc. 

  Building Materials: metal door, aluminum studs. 

  Electrical devices: microwaves, monitors and electrical motors. 

 

Solutions to overcome the interferences 

 

  Minimizing the number of walls and ceilings that wireless signal has to go 

through 

  Position the WLAN antenna for best reception. 

  Keep WLAN devices away from other electrical devices, eg: microwaves, 

monitors, electric motors … etc. 

  Add additional WLAN Access Points if necessary. 

 

 

IEEE 802.11 supports two subtypes of network authentication services: open system and 

shared key. Under open system authentication, any wireless station can request 

authentication. The station that needs to authenticate with another wireless station sends 

an authentication management frame that contains the identity of the sending station. The 

receiving station then returns a frame that indicates whether it recognizes the sending 

station. Under shared key authentication, each wireless station is assumed to have 

received a secret shared key over a secure channel that is independent from the 802.11 

wireless network communications channel.  

 

 

 

 

WEP is an optional IEEE 802.11 function that offers frame transmission privacy similar 

to a wired network. The Wired Equivalent Privacy (WEP) generates secret shared
