Two way radio systems

What is a two-way radio system?

A two-way radio is a technology that allows people to communicate with one another using radio waves. Each user is provided a radio device that is capable of transmitting (voice transmission) and receiving audio and data through radio waves.

A two-way radio might be as basic as two radios directly connected to each other or as complicated as an encrypted network covering a whole nation.

Two-way radio systems typically utilize a single radio channel and operate in half-duplex mode, which means that only one user on the channel at a time may transmit, hence users in a user group must take turns speaking to each other.

Normally, the radio is in receive mode, allowing the user to hear all other communications on the channel. When the user wants to communicate, they press a “push-to-talk” button, which shuts off the receiver and activates the transmitter; when the button is released, the receiver is enabled again.

Multiple channels are given so that different user groups can interact without interfering with one another in the same region, such as radios with multiple channels, they operate on one channel at a time.

Two-way radios may operate on a wide range of frequencies, which are designated differently in different nations.

Typically, channelized operations are used, so that operators do not need to tune equipment to a specific frequency but may instead use one or more pre-selected frequencies that can be quickly chosen using a dial, a pushbutton, or other means.

Other two-way radio systems work in full-duplex mode, which allows both sides to speak at the same time.

This necessitates the use of two independent radio channels or channel sharing mechanisms such as time-division duplex (TDD) to carry the two directions of the communication concurrently on a single radio frequency.

How does a two-way radio system work?

Two-way radio works by transforming sounds into radio waves, which are then transmitted over the air. These radio waves are picked up by other radios, which transform them back into audio.

The converted radio waves can be broadcasted as either an analog or digital signal, with digital transmission being the more current technique.

Other sorts of data, such as text messages and status updates, can be transmitted through radio waves using digital radio. It is also feasible to encrypt data while utilizing digital radio to prevent unauthorized users from accessing your network.

Can two-way radios be hacked?

Yes, many two-way radio users talk to each other about business until they hear a stranger voice speaking to them, saying malicious things, and threatening them. For example, many police officers have heard someone else speaking on their walkie-talkies while on duty.

So how can you prevent two-way radio hacking?


The use of a trunked radio system increases security. Request that to your two–way radio service provider to benefit from the greatest security measures for secure talks.


Look for systems that comply with the Advanced Encryption Standard (AES). These systems are becoming more widespread in police and fire departments that require secure conversations in which only authorized staff can participate.


Choose a two-way radio supplier with demonstrated competence in this field when seeking for a solution to handle or prevent two–way radio hacking.

They should give a list of references who have directly assisted with this issue. These sources help demonstrate the advantages of upgrading from a traditional system to a more secure system, as for example Starcom 21.
