Hytera is a pioneering organisation for DMR technology and digital migration. Whilst we understand that in certain circumstances Analogue is still a useful communication technology, Digital communications are no doubt a leap forward due to a variety of reasons.
Analogue signals are typically less tolerant to external noise interference and that means lots of unwanted background squeal, hiss and audio distractions that can get in the way of crisp and clear communications.
Oder anders gesagt: Durch Rauschen werden zusätzliche Informationen in analoge Signale eingefügt. Und mit jeder Verstärkung des Signals wird auch das Rauschen verstärkt.
The science bit
The science of noise is a fascinating topic in itself. We could discuss the many factors that affect audio quality, but instead let’s focus on why digital communications are clearer than analogue, especially in noisy conditions.
The audio processing in the radio focuses on speech and reduces any background noise. This means that the received audio quality is enhanced when compared to an analogue radio system. Digital technology also allows the receiving radios to auto-correct any errors in the received signal to maintain audio quality at the extremes of the radio coverage.
Our unique patented technology
As you’d expect, we’ve taken the basic properties offered by digital signals and built upon them with our research and development specialists. Our systems and transmission circuits are designed to minimise the impact of random interference. It all comes down to the unique way in which we package the transmission at one end – and unpack it at the other.
All our digital radios contain cutting-edge vocoder technology that filters communication channels, fills in microscopic gaps and breaks in transmission, and minimises error rates. That means that users always get to hear crystal clear messages from colleagues, with minimal interference or gaps.
Digital radio can make your communications clearer by reducing unwanted background audio and focusing on the wanted speech. Increased audio quality in poor coverage areas reduces the need to repeat information and improves efficiency.
