Term Stands For.... Meaning
LCP Link Control Protocol Basis of the Point-to-Point Protocol (PPP) scheme for negotiating
and establishing connections.
LDF see p.45
LED Light-emitting Diode An electronic device that lights up when electricity passes
through it. Often used to indicate equipment or system state.
LLC Logical Link Controller A protocol that governs the transition of frames between data
stations regardless of how the medium is shared. It’s the upper
sub-layer that further defines the Media Access Control (MAC)
protocol. It provides the basis for an unacknowledged
connectionless service on a LAN - i.e., error correction,
multiplexing, broadcasting.
LMR see p.45
LOS Line-of-sight Describes laser, microwave, RF, and infrared transmission
systems that require no obstruction in a direct path between the
transmitter and the receiver.
MAC Media Access Control Protocol that governs access to a network in order to transmit
data between nodes. In a wireless LAN, the MAC is the radio
controller protocol (L2).
Mb Megabit One million (1,000,000) bits.
MB Megabyte One million bytes. Literally - 1,048,576 bytes.
Mbps Megabits Per Second Transmission speed at rate of one million bytes per second.
MCBS Multi-Carrier Beam Forming
Synchronized
Multiple Access technology used by Navini Ripwave systems
MDM Modem Card A card in the Navini BTS that converts digital signals into analog
so the signals can be transmitted over telephone lines, and vice-
versa. Modem stands for modulator/demodulator.
MHz Megahertz One million (1,000,000) hertz - cycles per second. Normally used
to refer to how fast a microprocessor can execute instructions.
MIB Management Information Base A collection of managed objects used in SNMP-based networks.
MIBs carry information in a standard format so external tools can
analyze network management and performance.
MMDS Multipoint Multi-channel
Distribution Service
Fixed wireless, high-speed local service that operates at 2.1 - 2.7
GHz. Speed 10 Mbps. Originally conceived for cable TV service.
MME see p.92
NE
1
Near-end or
2
Network Element
1
The transmitting end, versus the receiving end, of a signal
transmission.
2
A router, switch, or hub in an ISDN network.
NEC
National Electrical Code
Official rules and regulations that apply to the installation of
electrical equipment in the U.S.
NF
Noise Floor
NIC
Network Interface Card
A computer circuit board or card that is installed in a computer
so that it can be connected to a network. Network interface cards
provide a dedicated, full-time connection to a network.
NLOS
Non Line
-of-site Describes laser, microwave, RF, and infrared transmission
systems that can penetrate obstructions in the path between the
transmitter and the receiver.
NMS
Network Management System
A product that helps manage a network generally hosted on a
well
-
equipped computer such as an engineering workstation. The
system tracks network statistics and resources.
NOC
Network Operations Center
A centralized point, much like a traffic control tower, where
technicians or engineers can monitor network activity, alarms,
and statistics, as well as make network configuration and other
changes dynamically. For Internet, the NOC is often a hub for
ISP services.
