Power source
▶Speed of installation
▶Flexible means of communications
▶Can span great distances
▶Provides communications across
impassable terrains
▶Requires minimum manpower and space
for equipment.
▶Integrates with wire system
MEANS OF COMMUNI CAT ION
Least secured means of
communications
Subject to noise and interference
Radio operations requires
common freq, compatible
equipment and common range
RADIO: WEAK POINTS
- is the use of field wires,
combat wires, drop wires
and telephone cables
Wires and cables
– is one of the most dependable
communication means
Wire Comm
- a group of metallic conductors, insulated
from each other and made up by pairs into one unit
with a suitable continuous covering of sheath
CABLE
: Advantages
More secure than radio.
Reduces probability of interception.
Desirable in defensive operations.
WIRES & CABLES
Concerned with communications of
information using still photographs,
graphic illustrations, sounds and
signaling.
Visual and sounds
Numerous means (flags, lights,
panels, arm and hand signals,
pyrotechnics, armbands, horns
bells, whistles, weapon fires
and sirens).
VISUAL & SOUNDS: MAIN FEATURES
Use to mark locations.
Good for passing information to
large numbers and to isolated
units, passage of lines and
linkup operations
Visual and sounds strong points
: MAIN FEATURES
Reliable
Flexible
Most secure means available
to all unit

VISUAL COMMUNI CAT ION
Group of several stations working together in the
same frequency
Radio Net
A combination of pronounceable words that
identifies the facility or station
Call Sign
Identifies the single call to any station within the
net
Individual Call Sign
Identifies two or more stations in a particular radio
net but not all stations in the net
Collective Call Sign
Identifies all radio stations operating in a
particular radio net
Net Call Sign
A method of establishing communication
whereby the station calling transmits the identity
of the station called as well as his own identity
