Theory Of Operation
A LINKNET CDMA PCS MODULE is a banded repeater amplifier. The most
common LINKNET CDMA PCS 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 CDMA PCS MODULE is very similar
to a regular two-way radio repeater. On Frequency Radio Repeaters 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 CDMA PCS MODULE
systems is that of input to output antenna isolation. This must be carefully
engineered for each installation.
The Modules are designed for indoor use only and are intended for mounting in a
standard EIA 19 inch rack. Modular design of LINKNET CDMA PCS MODULE
circuitry allows for easy servicing, stocking of spares, adaptability and upgrade
ability.
