Access Point
An Access Point is a wireless hub that provides wireless workstations
access to wired Ethernet LANs. It also contains the wireless relaying
functions that enable workstations equipped with a wireless adapter to
communicate with one another.
Ad-Hoc
A group of 2 or more wireless workstations that communicate directly
with one another without the need for a central AP (peer-to-peer).
Authentication
Type
• Open System: A null authentication algorithm (no
encryption).
• Shared Key: Requires workstations to have a secret
key installed for authentication.
NOTE: Open System authentication is the default
authentication algorithm in BreezeNET products.
BSS
Basic Service Set. An Access Point and all wireless workstations.
Several BSSs form an ESS (Extended Service Set).
DSSS
Direct sequence spread spectrum.
ESS
Extended Service Set. More than one BSS can be configured to
become an Extended Service Set. LAN mobile users can roam
between different BSSs in an ESS.
ESSID
In Infrastructure mode – all associated workstations and APs must
have the same ESSID.
Fragmentation
Threshold
Fragmentation Threshold determines the largest possible data packet
transmitted. Transfer reliability can be increased by cutting a MAC
Service Data Unit (MSDU) into several smaller MAC Protocol Data
Units (MPDU).
