BreezeMAX Wi² and BreezeACCESS Wi² System Manual 259
MAC Media Access Control: The lower of the two sub-layers of the
data link layer defined by the IEEE. The MAC sub-layer
handles access to shared media, such as whether token
passing or contention will be used.
MAC Address
Standardized data link layer address that is required for every
port or device that connects to a LAN. Other devices in the
network use these addresses to locate specific ports in the
network and to create and update routing tables and data
structures. MAC addresses are 6bytes long and are controlled
by the IEEE.
NTP Network Time Protocol: NTP provides the mechanisms to
synchronize time across the network. The time servers operate
in a hierarchical-master-slave configuration in order to
synchronize local clocks within the subnet and to national time
standards via wire or radio.
ODFM Orthogonal Frequency Division Multiplexing: OFDM/ allows
multiple users to transmit in an allocated band by dividing the
bandwidth into many narrow bandwidth carriers.
Open System A security option for the AP which broadcasts a beacon signal
including the configured SSID. Wireless clients can read the
SSID from the beacon, and automatically reset their SSID to
allow immediate connection to the nearest AP.
PoE Power over Ethernet: A specification for providing both power
and data to low-power network devices using a single Category
5 Ethernet cable. PoE provides greater flexibility in the locating
of Wi²s and network devices, and significantly decreased
installation costs.
PSK WPA Pre-shared Key: PSK can be used for small office
networks that may not have the resources to configure and
maintain a RADIUS server, WPA provides a simple operating
mode that uses just a pre-shared password for network access.
RADIUS Remote Authentication Dial-In User Service: A logon
authentication protocol that uses software running on a
central server to control access to the network.
Session Key Session keys are unique to each client, and are used to
authenticate a client connection, and correlate traffic passing
between a specific client and the Wi².
