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
