VHF Radio Communication Hydro-Electric Power Plant: Xe-Pian Xe-Namnoy

This document provides an overview of radio communication modes used at KOWEPO-LAO International Company's hydroelectric power plants. It discusses simplex mode for point-to-point communication over limited distances. Repeater mode uses a repeater to transmit signals over a wider area with more power. Trunking mode shares a pool of frequencies among many users via a central controller. The document demonstrates these modes with examples of radio equipment used at different locations within their power system.

Simplex Mode of Radio Communication


Internal Training Program

Repeater
Radio transmits to a “repeater” that re-transmits the
signal (Repeats) to a wider area, generally with a more
powerful signal
Ties up a pair of frequencies – the input to, and the
output from the repeater
Can have a large area of coverage
Used in Power House and Power Intake

Repeater Mode of Radio Communication


Internal Training Program

Trunking
A generic term used to describe the sharing of a limited number of repeater
frequencies (or trunks) among Many Users
Uses a group of similar radio frequencies to create a “pool” for radio system
users to access.
A Channel (on your radio) is now a computer-generated code …and is now
referred to as a “Talk Group”
The entire system is managed by a “Central Controller”
All radios in the system also are computer-controlled, and communicate to
the central controller via one frequency known as the “Control Channel”
