Radio Communication (2 weeks) Short Course at Botswana Wildlife Training Institute (BWTI)
What is Radio Communication?
Radio is the technology of signaling and communicating using radio waves.[1][2][3] Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications.

Radio is a type of wireless communication that uses electromagnetic waves in the radio frequency range to transmit information from one place to another.
Frequently Asked Questions
What do you mean by radio communication?
The term “radio communication” or “communication by radio” means the transmission by radio of writing, signs, signals, pictures, and sounds of all kinds, including all instrumentalities, facilities, apparatus, and services (among other things, the receipt, forwarding, and delivery of communications) incidental to such ..
What is an example of radio communication?
In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information ..
What is the importance of radio communication system?
In fact, unlike cellular devices, two-way radios send and receive messages with any action from the intended recipient, and are not dependent on phone lines or cell towers. Additionally, they are cost-effective, without monthly maintenance fees, without overage fees, and without recurring expenses.
What are the three types of radio?
Types of Radios
- AM Radio. AM radio stands for amplitude modulation, and it’s one of the oldest types of wireless broadcasting.
- FM Radio. Many people who listen to the radio in their car listen to FM radio.
- Shortwave Radio.
- Satellite Radio.
- Ham Radio.
- Walkie-Talkie.
What is the difference between line communication and radio communication?
Types of Communication Systems
Line communication systems: Uses the existing infrastructure of power lines to transfer data from one point to another point. Radio Communication systems: uses the infrastructure of radio waves to transfer the information from one point to another point.
What are the three elements of radio communication?
This system consists three basic components: transmitter, channel, and receiver.
What are two-way radio communication examples?
Termed ‘two-way’ because of its ability to both send and receive signals, these types of radios are designed for person-to-person, bidirectional voice communications. Often constructed in a stationary or mobile base, the most well-known example of a two-way radio is the walkie-talkie.
What is the benefits of radio communication channels?
Radio has the ability to raise awareness and stimulate social change amongst the target audience.
How does radio work?
Radio works by transmitting and receiving electromagnetic waves. The radio signal is an electronic current moving back and forth very quickly. A transmitter radiates this field outward via an antenna; a receiver then picks up the field and translates it to the sounds heard through the radio.
What was the first name of radio?
In 1895, a young Italian named Gugliemo Marconi invented what he called “the wireless telegraph” while experimenting in his parents’ attic. He used radio waves to transmit Morse code and the instrument he used became known as the radio.
