CONFIDENTIAL & PROPRIETARY

Java™ Runtime Environment

See JRE.

JRE

Java™ Runtime Environment. Software platform that enables Java

applications to execute. The IFU Link Manager software requires JRE.

Java™ virtual machine

Software, created for specific hardware platforms (microprocessors), that

interprets compiled Java code (bytecode) using the microprocessor’s 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.

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 (Global Positioning System) coordinates of the angle for an IFU linked

pair.

link budget

The sum of transmission gains and 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, receiver sensitivity, and

antenna gains.

link manager

See IFU Link Manager.

LMDS

See Local Multipoint Distribution Service (LMDS).

Local Area Network (LAN)

See LAN.
