HiPath Wireless Controller, Access Points and Convergence Software V4.0, C10/C100/C1000 User Guide
Explanation
A thin AP architecture uses two components: an access point that is
essentially a stripped-down radio and a centralized management
controller that handles the other WLAN system functions. Wired
network switches are also required.
A fit AP, a variation of the thin AP, handles the RF and encryption, while
the central management controller, aware of the wireless users'
identities and locations, handles secure roaming, quality of service,
and user authentication. The central management controller also
handles AP configuration and management.
A fat (or thick) AP architecture concentrates all the WLAN intelligence
in the access point. The AP handles the radio frequency (RF)
communication, as well as authenticating users, encrypting
communications, secure roaming, WLAN management, and in some
cases, network routing.
Fully Qualified Domain Name. A "friendly" designation of a computer,
of the general form computer.[subnetwork.].organization.domain. The
FQDN names must be translated into an IP address in order for the
resource to be found on a network, usually performed by a Domain
Name Server.

File Transfer Protocol
In the wireless world, an access point with additional software
capabilities such as providing NAT and DHCP. Gateways may also
provide VPN support, roaming, firewalls, various levels of security, etc.
The high data rate of the Ethernet standard, supporting data rates of
1 gigabit (1,000 megabits) per second.
Graphical User Interface
A heartbeat message is a UDP data packet used to monitor a data
connection, polling to see if the connection is still alive.
In general terms, a heartbeat is a signal emitted at regular intervals by
software to demonstrate that it is still alive. In networking, a heartbeat
is the signal emitted by a Level 2 Ethernet transceiver at the end of
every packet to show that the collision-detection circuit is still
connected.
