INTEROPERABILITY




The ability of systems, units, or forces
to provide services to and accept services
from other systems, units or forces and to
use the services so exchanged to enable
them to operate effectively together.
The condition achieved among systems or
items of communications-electronics
equipment when information or services
can be exchanged directly and the
satisfactorily between them and/or their
users. The degree of interoperability
should be defined when referring to
specific cases.

Source: Department of Defense Dictionary
of Military and Associated Terms in
support of MIL-STD-188. With respect to
software, the term interoperability is
also used to describe the capability of
different programs to read and write the
same file formats and utilise the same
title protocols. Interoperability can
have important economic consequences,
such as network externalities.

If competitors' products are not
interoperable (due to causes such as
patents, trade secrets or coordination
failures), the result may well be

monopoly or market failure. For this
reason, it may be prudent for the
governments to take steps to encouage
interoperability in various situations.

AMATEUR
RADIO
HAM RADIO




Amateur radio, often called ham radio,
is a hobby enjoyed by about 3 million

people throughout the world.
An amateur radio operator, also know
as a ham or radio amateur, uses two-way
radio equipment to communicate with other
radio amateurs for public service, for
recreation and self-training.

Amateur radio operators enjoy personal
two-way communications with friends,
family members, and complete strangers,
all of whom must also be licensed.
They support the larger public community
with emergency and disaster communications.
Increasing a person's knowledge of electronics
and radio theory as well as radio contesting
are also popular aspects of amateur radio.


AMATEUR RADIO LICENSING:

In most countries, amateur radio operators are
required to pass an exam displaying knowledge
and understanding of key concepts.
This practice is in contrast to other personal
radio services such as CB radio, Multi-Use Radio
Service, or Family Radio Service / PMR446 that
are unlicensed and more heavily restricted.

In return, hams are granted operating privileges
in larger segments of the radio frequency spectrum
using a wide variety of communication techniques
that would otherwise be unavailable to them.

Hams are also allowed to use equipment that they
have either built themselves or modified from
existing commercial or amateur gear.

This privilege is unavailable in
virtually any other radio service.

CITIZENS
BAND RADIO




Citizens' Band radio (CB) is, in the
United States, a system of short
distance radio communication between
individuals on a selection of 40
channels within the single 27 MHz
(11 meter) band.
The CB radio service should not be
confused with FRS, GMRS or amateur
radio. CB does not (in most countries)
require a license and unlike amateur
radio, CB may be used for commercial
communication. Similar personal radio
services exist in other countries, with
varying requirements for licencing and
differing technical standards.

To simplify selection of an operating
frequency, the Citizens' Band radio
spectrum is divided into 40 numbered
radio frequency channels from 26.965
to 27.405 MHz, with channels generally
spaced 10 kHz apart.
Channel numbers are not strictly
sequential with frequency;
there are gaps for frequencies used by
radio-controlled devices.

In the United States Citizens' Band (CB)
radio service is intended to be a private
two-way voice communication service for
use in personal and business activities
of the general public.
Its communications range is from one to
five miles. The Citizens' Band radio
services are described in part 95 of the
Federal Communications Commission's (FCC)
and is defined as a personal radio service.

EMERGENCY
COMMUNICATIONS




In times of crisis and natural disasters,
ham radio is often used as a means of
emergency communication when wireline and
other conventional means of communications
fail.

where amateur radio was used to coordinate
disaster relief activities when other systems
failed. Amateur radio operators who are
involved in emergency communications often
belong to a national or local emergency club.

SHORTWAVE
RADIOS




A shortwave radio gets stations from
places far away from where you live
and are "hidden" in between the
standard AM and FM band on the
frequencies from about 3 Mhz to
30 Mhz.

These stations broadcast to foreign
countries, in the language of the
people in the foreign countries.

Shortwave radio operates between the
frequencies of 2,310 kHz and 30.000 MHz
(30,000 kHz),the wavelengths associated
with this frequency range were shorter
than those commonly in use at that time.

An alternate name is HF or high frequency
radio. Short wavelengths are associated
with high frequencies because there is an
inverse relationship between frequency and
wavelength.
