SSID
Each
ESS
has a Service Set Identifier (
SSID
) used to identify the
Radio
that belong to the
ESS
.
Radios
can be configured with the
SSID
of the
ESS
to which they should associate. By default, radios broadcast
their
SSID
to advertise their presence.
VLAN
A
VLAN
is a switched network that is logically rather than physically segmented.
VLAN
s enable
workstations and other devices to have a virtual association - independent of geographic location or
physical attachment to the network. These groupings can be based upon organizational unit, application,
