There are many ways to keep in touch, especially now that various devices and networks are available. Certain industries, however, continue to rely on time-tested methods. Radio is still one of the most reliable means of facilitating group communication.
VertexStandard.com/ap says that 2 way portable radios are still used by countless organisations worldwide for their daily communication needs, even with the proliferation of mobile phones. These devices transmit and receive radio signals. The more popular names for two-way radios are handie-talkies or walkie-talkies.
Pocket-sized and easy to operate
The communication range for two-way radios is within 150MHz to 900MHz. Line of sight governs radio waves, which means that the waves cannot travel beyond the horizon. Once they pass the horizon, the waves just proceed straight into space. In fact, radio waves are present throughout the universe.
Radio waves at these frequencies travel in a straight line, but they are strong enough to penetrate walls and non-metallic objects in their path. Certain surfaces also reflect and bounce off radio waves.
When you operate a walkie-talkie and want to send word out, all you need to do is press a button, which then activates the transmitter function of the device. Once you have completed your message, you have to let go of the button and wait for the response.
Effectively addresses communication needs
Many different industries depend on radio technology. Examples of which are medical and emergency response and disaster recovery groups. Firefighters and the police also make use of walkie-talkies in their daily operations.
Utility companies, transport systems, construction workers and manufacturing groups all use portable radio communication. Employees in these sectors can send out messages directly, without relying on third-party communication companies, such as mobile phone operators.
Even with everyone having access to mobile phones, radio will continue to serve its purpose. It is a useful means of communication, especially in locations where mobile phone coverage is poor.
