E
The WiMAX standard that provides mobile broadband wireless access using
Scalable Orthogonal Frequency Division Multiple Access (SOFDMA).
IEEE 802.1X
Port Authentication controls access to the switch ports by requiring users to
first enter a user ID and password for authentication.
IP A
DDRESS
The Internet Protocol (IP) address is a numerical identification assigned to
a device that communicates in a network using the Internet Protocol.
ISP

connects customers to the Internet.
LED
Light emitting diode. Used for indicating a device or network condition.
LAN
Local Area Network. A group of interconnected computer and support
devices.

The physical layer address used to uniquely identify network nodes.
MS-CHAPV2
Microsoft’s version 2 of the Challenge-Handshake Authentication Protocol.
Introduced by Microsoft with Windows 2000, MS-CHAPV2 (defined in RFC
2759) provides mutual authentication between peers using user names
and passwords.
ODFM
Orthogonal Frequency Division Multiplexing. The air interface defined for
IEEE 802.11g Wi-Fi. OFDM allows multiple users to transmit in an allocated
band by dividing the bandwidth into many narrow bandwidth carriers.
RADIUS
Remote Authentication Dial-in User Service. A logon authentication
protocol that uses software running on a central server to control access to
a network.
RJ-45 C
ONNECTOR
A connector for twisted-pair wiring.
RSSI
Receive Signal Strength Indicator. A measurement of the strength of a
received wireless signal. The higher the RSSI value, the stronger the
received signal from the antenna.
R
OAMING
The process where a WiMAX subscriber can move onto another operator’s
network while maintaining a continuous connection.
