Java virtual machine
Software, created for specific hardware platforms (microprocessors), that
interprets compiled Java code (bytecode) using the microprocessors set of
instructions. Java virtual machines enable any Java application (bytecode) to
run on any platform without requiring the programmer to rewrite or recompile
the application for each platform.
L
LAN
Local Area Network. Integrated data communication network (linking
computers and peripheral devices) designed to provide services to a closed
user community. See also MAN and WAN.
line-of-sight
Straight line of space between a transmitter and receiver. The space between a
transmitter and receiver must be clear of obstructions because the
transmission media (such as microwave, infrared, and laser) travel in a
perfectly straight line.
link angles
GPS coordinates of the angle for an IFU linked pair.
link budget
The sum of transmission losses between transmitter and receiver. The total
should be equal to or less than the system gain. The link budget is configured
using the transmitted signal power and signal-to-noise ratio (SNR), the
antenna gains, implementation degradation, and the noise figure of the
receiver.
link manager
See IFU Link Manager.
LMDS
See Local Multipoint Distribution System (LMDS).
Local Area Network (LAN)
See LAN.
Local Multipoint Distribution System (LMDS)
Broadband wireless spectrum over which telephony and data services are
delivered.
loop back
Directing signals back toward the transmitting device at some point along the
communications path. Used as a method for troubleshooting.
