Overview
Theory Of Operation
An LINKNET FM MODULE is a radio repeater that simultaneously receives and
transmits a single narrow band radio channel on exactly the same frequency.
The LINKNET FM MODULE accomplishes its repeater function without store and
forward circuitry, or expensive conventional simulcasting techniques. The fact that
the same frequency is retransmitted by an LINKNET FM MODULE means that
additional frequency allocations are not required in situations where an existing radio
coverage pattern needs to be extended. The most common LINKNET FM MODULE
applications are the extension of above ground signals into buildings, tunnels,
vehicles or the extension of radio coverage patterns into outdoor shaded areas such
as deep valleys.
From an applications standpoint, an LINKNET FM MODULE is very similar to a
regular two-way radio repeater. LINKNET FM MODULES can be combined using
regular two-way radio multicoupling or duplexing equipment and have input and
output signal characteristics to those of regular transmitters and receivers. The one
special consideration in LINKNET FM MODULE systems is that of input to output
antenna isolation. This must be carefully engineered for each installation.
LINKNET FM MODULES are designed for indoor use only and are intended for
mounting in a standard EIA 19 inch rack. The Modular design of LINKNET FM
MODULE circuitry allows for easy servicing, stocking of spares, adaptability and
upgrade ability.
