What is SSID?
Service Set Identifier - effectively the name of the network, to
distinguish
it from other networks that might be within network range of a PC
that wants
to connect to the network.
By not broadcasting the SSID, any PC that wants to connect to a
network must
be configured with the network's SSID - and if it can't supply that
SSID, it
doesn't connect.
The SSID is a name which is used in software to help users decide which
network to connect to. If you set your laptop up to always connect to
'myCompany' then it will connect to any channel with an access point
called 'myCompany'.
That is the only use of the SSID, simply hiding it doesn't do much
because a client could still try to connect to 'channel 5' and doesn't
need to know the SSID in order to do this.
