GLOSSARY
10BASE-T IEEE 802.3-2005 specification for 10 Mbps Ethernet over two pairs of
Category 3 or better UTP cable.
100BASE-TX IEEE 802.3-2005 specification for 100 Mbps Fast Ethernet over two pairs of
Category 5 or better UTP cable.
1000BASE-T IEEE 802.3ab specification for 1000 Mbps Gigabit Ethernet over four pairs
of Category 5 or better UTP cable.
ACCESS POINT 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.
ADVANCED ENCRYPTION
STANDARD (AES)
An encryption algorithm that implements symmetric key cryptography. AES
provides very strong encryption using a completely different ciphering
algorithm to TKIP and WEP.
AUTHENTICATION 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.
BACKBONE 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.
BEACON A signal periodically transmitted from the access point that is used to
identify the service set, and to maintain contact with wireless clients.
BROADCAST KEY 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.
