OINT
An internetworking device that seamlessly connects wired and wireless
networks. Access points attached to a wired network, support the creation
of multiple radio cells that enable roaming throughout a facility.

TANDARD
(AES)
An encryption algorithm that implements symmetric key cryptography. AES
provides very strong encryption using a completely different ciphering
algorithm to TKIP and WEP.

UTHENTICATION
The process to verify the identity of a client requesting network access.
IEEE 802.11 specifies two forms of authentication: open system and
shared key.
B
ACKBONE
The core infrastructure of a network. The portion of the network that
transports information from one central location to another central location
where it is unloaded onto a local system.
B
EACON
A signal periodically transmitted from the access point that is used to
identify the service set, and to maintain contact with wireless clients.

Broadcast keys are sent to stations using dynamic keying. Dynamic
broadcast key rotation is often used to allow the access point to generate a
random group key and periodically update all key-management capable
wireless clients.
