Communication radios are devices that use electromagnetic waves to transmit messages from one end to the other. These can be useful for situations where mobile phones cannot be used to communicate. Some examples of such situations can be hiking, military usage, etc.

This article will go through all such communication radio devices and wireless PA systems.

What Are Wireless PA Systems?

A wireless PA system is a system that can be used in offices, warehouses, schools, and other buildings where a large number of people need to hear a message.

These systems are essential for safety reasons as well as other reasons. These can also act as alarm bells, which can ring at specified times. These can be used to let people know about a meeting or break or to evacuate the crowd in case of an emergency like a fire hazard.

Types Of Communication Radios

There are several types of different communication radios. Let us go through them one by one.

Ham radio

These radios are used by hobbyists and amateurs. These megaphones are available as walkie-talkies and can be carried freely without connecting them with any cords or antennae.
To use these, you need to have a legal license. There are three levels to acquiring this license.

Airband radio

These radios are used in the aviation industry to transmit messages from air to ground or ground to air. Because of this, the range of these radios is very good.

CB Radio

This type of radio is known as citizen band radio and is normally available to the general public. These are shortwave radios with a low range of reach.

Survival radio

These kinds of radios are present in aircraft and ships. These are essential to prevent any mishaps in case of an emergency. These transmit signals to international frequencies, which means even a very weak frequency will be detected when transmitted from these radios.

Police radios

These radios are primarily used for communication by police officers and in police stations. As these radios are encrypted, they cannot be used by anyone other than police officers.

Satellite radio

These radios are among the newer technologies used in broadcasting. These are different from other radios in that they use a special receiver to receive the transmitted message. These are based on a special code, and you need to have a paid subscription to be able to use them.

Two way radio

These radios are specially used to communicate simultaneously as they can transmit and receive signals in the form of audio simultaneously. These can be used to transmit in the form of voice and receive in the form of voice.

Some Protocols You Should Follow While Using Communication Radios

You should always let the other person finish their sentence before you go on to start your own. This will prevent any misunderstandings or miscommunication.

Always be aware that the channels you use to communicate over the radio are open and can be scanned or checked by others. So, you should always make sure you are not giving out any of your confidential information, as it can be used against you if leaked.

Always ensure that your radio devices are charged and have enough battery to get you through the day without dying. This factor is very important as not having the power to communicate can even create a life-threatening situation for a person.

Bottom line

Whether you are buying Public address systems or communication radios, make sure to account for the crowd strength to address and the core purpose of the gadget. Evaluating certain aspects help you lay hands on the best device.
