IEEE 802.11

 Standard 

The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a 
standard for the industry.   
 

Access Point 

An internetworking device that seamlessly connects wired and wireless networks 
together. 
 

Ad Hoc   

An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter, 
connected as an independent wireless LAN. Ad Hoc wireless LAN is applicable at a 
departmental scale for a branch or SOHO operation. 
 

BSSID 

A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS 
must be configured with the same BSSID. 
 

DHCP 

Dynamic Host Configuration Protocol - a method in which IP addresses are assigned 
by server dynamically to clients on the network. DHCP is used for Dynamic IP 
Addressing and requires a dedicated DHCP server on the network. 
 

Direct Sequence Spread Spectrum 

This is the method the wireless cards use to transmit data over the frequency 
spectrum. The other method is frequency hopping. Direct sequence spreads the data 
over one frequency range (channel) while frequency hopping jumps from one narrow 
frequency band to another many times per second. 
 

ESSID 

An Infrastructure configuration could also support roaming capability for mobile 
workers. More than one BSS can be configured as an Extended Service Set (ESS). 
Users within an ESS could roam freely between BSSs while served as a continuous 
connection to the network wireless stations and Access Points within an ESS must 
be configured with the same ESSID and the same radio channel. 
 

Ethernet 

Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users 
must be wired to the network at all times to gain access.
