The document discusses radio frequency (RF) spectrum and different RF sub-bands. It defines RF as the range between 3 kHz and 300 GHz responsible for digital wireless communication. It then describes some common uses of RF including aircraft navigation, satellite systems, and mobile networks. Several RF sub-bands are outlined like Very Low Frequency and Medium Frequency, and their typical uses and characteristics. The document emphasizes that an RF spectrum analyzer is needed to determine the working and problems in different RF bands critical to modern communication systems.

1. Have A Look At
Different Bands of RF
Sub-bands

2. RF spectrum analyzer is one of
the major equipment that
many internet connection
providers need to add. The
reason is that they are used to
track the problems arising in
RF spectrum. By using this
analyzer, one can determine
the source and exact
frequency of the interference.

3. What is
Radio
Frequency?
Radio frequency is the
smallest part of the EM
(electromagnetic) wave
spectrum and is
responsible for digital
wireless communication
system. The range of RF
lies between 3 KHz and
300 GHz.

4. Where
can RF be
used?
It is used almost in every industry
including-
Aircraft navigation
Satellite systems
Marine radio
TV broadcasting
Amateur radio and
Mobile networks

5. Different RF Sub-bands
Extremely Low Frequency
(ELF)- Under this band, the
frequency starts in the em
spectrum, i.e. 3Hz to 3 KHz.
Frequency under this band can
easily be distorted by
atmospheric or environmental
changes.

6. Different RF Sub-bands
Very Low Frequency (VLF)-
VLF has a frequency span from
3 KHz to 30 KHz. The design
and installation of the antenna
system are quite complex due
to the wavelength. It is used in
submarines, radio station
which synchronizes clock
signals between two remote
locations.

7. Different RF Sub-bands
Low frequency (LF)- This has a
range from 30 KHz to 300 KHz. LF
is easily reflected by the
ionosphere present above the
earth. This can be easily used for
long distances communication
purposes. It gets less attenuated
from the large and harsh terrains
such as mountains. It is also
known as ground waves.

8. Different RF Sub-bands
Medium Frequency (MF)- It is the
most popular frequency band
since the starting of wireless radio
transmission that is- the early 19th
century. Today, they are used for
less complex design and working.
MF has been used in AM radio
transmission, navigation systems
for ships and aircraft, emergency
distress signals, cost guards and
other experimental applications.

9. To determine the working of these bands you
need RF spectrum analyzer. Because our
communication system will depend totally on
high-frequency bands of RF spectrum since it
can support higher bandwidth.
