Access Point
A wireless LAN adapter, which connects to a wired LAN network (acting as a bridge) and serves as the base for a
wireless LAN network, directing communication between clients. An access point is only used in Infrastructure
mode. Access Points in a business environment are typically connected to the wired LAN network. In the home,
an Access Point would be connected to a broadband Internet device such as a Cable or ADSL modem.
Ad-Hoc
This is a wireless LAN network comprised solely of clients (no access points), which can communicate with each
other only when they are in range of each other’s Signal and configured to the same channel and SSID.
BSS – Basic Service Set
This denotes the availability of access points and clients, all in communication with each other. An Ad-Hoc LAN
(clients only) may also have a BSS ID; all machines must use the same BSS ID.
Client
A PC, peripheral or other electronics with a connection to the network, with the sole purpose of using the
network for data access and transfer. For example, a notebook PC with the Wireless LAN Card is considered a
client.
ESS – Extended Service Set
The availability of access points and clients (BSS) and connections to wired networks, as well as the ability for a
client to roam. ESS is available in Infrastructure mode, and all components must have the same ESS ID. Clients
within an ESS may roam freely through many BSSs, if they are within range of the wireless LAN networks.
Infrastructure
As opposed to Ad-Hoc, this network mode allows connection to access points and to wired LAN networks or
Internet access device such as a cable or ADSL modem.
