4.1.1
Suppress SSID broadcast – closed network
Every wireless LAN compliant with IEEE 802.11 has its own network name
(SSID). This network name facilitates the identification and servicing of wire-
less LANs.
A wireless LAN can be set up so that any user has access. These networks are
known as open networks. An open network is accessible to users even if they
do not know the network name. Access is possible simply by entering the net-
work name 'ANY'.
A closed network denies access to clients trying to access 'ANY' The user must
enter the correct network name for this to work. Hidden networks remain invi-
sible.
