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 personal 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). Personal 
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. 
Gateway 
A gateway is a hardware and software device that connects two dissimilar
