What is Radio Frequency
It is a frequency or band of frequencies in the range 10 to 10 or 10 Hz, suitable
for use in telecommunications.
Historical Background Of Radio Frequency
The early history of radio is the history of technology that produces and uses radio instruments that
use radio waves. Within the timeline of radio, many people contributed theory and inventions in what
became radio. Radio development began as "wireless telegraphy". Later radio history increasingly
involves matters of broadcasting.
How Does it Work
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage
or of a magnetic, electric or electromagnetic field or mechanical system in the
frequency range from around 20 kHz to around 300 GHz. This is roughly between the
upper limit of audio frequencies and the lower limit of infrared.
companies who are producing Radio frequency
● Vizinex RFID
● Omni-ID
● IMPINJ
● Avery Dennison Corporation
● Atlas RFID Solutions
These companies provide radio frequency identification solutions to businesses and
governments1. They are involved in the radio frequency identification market 2.
ADVANTAGE AND DISADVANTAGE
Advantages of radio frequency (RF): It is
used in radar for object detection. It is used
for satellite communication. It is used for
radio and television transmission and for
cellular mobile phone service. It is used in
the microwave line of the sight
communication system.
disadvantage: Uncontrolled radiation of RF affects
pre-adolescent children, pregnant women, elderly
humans, patients with pacemakers, small birds,
flora and fauna, small insects etc.
