Identify a Wireless Network
Depending on the size and components of a wireless network, there are many ways
to identify a wireless network:
●
The Network Name or Service Set Identifier (SSID):
Identifies a wireless
network. All wireless devices on the network must use the same SSID.
●
Extended Service Set Identifier (ESSID):
A special case of SSID used to
identify a wireless network that includes access points.
●
Independent Basic Service Set Identifier (IBSSID):
A special case of
SSID used to identify a network of wireless computers configured to
communicate directly with one another without using an access point.
●
Basic Service Set Identifier (BSSID):
A unique identifier for each wireless
device. The BSSID is the Ethernet MAC address of the device.
●
Broadcast SSID:
An access point can respond to computers sending probe
packets with the broadcast SSID. If this feature is enabled on the access
point, any wireless user can associate with the access point by using a blank
(null) SSID.
●
Basic Service Set (BSS):
Consists of two or more wireless nodes, or
stations, which have recognized each other and have established
communications.
●
Independent Basic Service Set (IBSS):
A mode of operation in an 802.11
system that allows direct communication between 802.11 devices without the
need to set up a communication session with an access point.
Select a Wireless Network Mode
Wireless networks can operate with or without access points, depending on the
number of users in the network. Infrastructure mode uses access points to allow
wireless computers to send and receive information. Wireless computers transmit to
the access point, the access point receives the information and rebroadcasts it to
other computers. The access point can also connect to a wired network or to the
Internet. Multiple access points can work together to provide coverage over a wide
area.
Device-to-Device mode, also called ad hoc mode, works without access points and
allows wireless computers to send information directly to other wireless computers.
You can use Device-to-Device mode to network computers in a home or small office
or to set up a temporary wireless network for a meeting.
