News from us - How do digital two-way radio communications work?

M.R.S. Communications uses two-way radio as a cornerstone of its security systems. But how does two-way radio work, and what benefits does it confer to its users? We look into how two-way radio communications operates here.

Analogue vs digital radio

“Two-way radio communication” may conjure up an image of crackly walkie-talkies, but the systems have come a long way since the analogue equipment of yesteryear. While such analogue systems were limited in many ways, current digital two-way radio is altogether more sophisticated.

At its most simple, a two-way radio system can both receive and broadcast audio, via a transceiver.

While analogue systems broadcast on specific radio frequencies, digital mobile radio (DMR) systems allow for the digitisation of audio. This effectively converts what’s being broadcast into data – zeroes and ones, if you like.

Two of the primary advantages of a digital system are clarity and range. In the case of the former, having crystal-clear audio means that messages are far less likely to be misheard, which can be critical when information needs to be acted on in a timely fashion. And increasing the range means that a larger area can be covered – so the net of communication can be cast wider.

Digital radio is more secure

But modern digital radio systems offer further benefits beyond the obvious. Crucially, these systems of communication are far more secure. One of the disadvantages of analogue radio is that all frequencies are discoverable, meaning that third parties can tune in. This is far from ideal when the information being communicated is of a sensitive nature.

Digital systems are much more difficult to compromise. Dedicated paths of communication mean that only the intended recipients will receive the information communicated, and third parties can’t unexpectedly jump in. In other words, anything communicated over the secure channel is very unlikely to fall into the wrong hands.

For additional security, data can be encrypted over digital channels. This means it can only be understood by authorised users who have a secure key, which is used to decode encrypted messages. So even if data is intercepted by potentially malicious actors, it’ll be indecipherable.

GDPR compliance

This extra level of security means that any firm or organisation using this technology can comply with General Data Protection Regulations (GDPR). These are strict regulations designed to safeguard citizens’ personal data.

By way of example, if a person’s whereabouts were broadcast over the radio channel, an interception by a third party may constitute a very serious data breach. However, if the data is completely unintelligible to the third party, then the required safeguards have been met.

How two-way radio benefits businesses

At its heart, a system of two-way radio allows users to communicate quickly and effectively with one another. Businesses and professionals who have bought into this system will be better able to cooperate in preventing crime and keeping their communities safe.

For instance, if thieves or troublemakers are operating in an area, then this can be communicated quickly to the entire network so that everyone is prepared.
