With the arrival of Codan's second generation of Digital Voice technology and advanced signal processing, poor voice quality is becoming a thing of the past.
Both public safety and tactical organisations require long-range communications in remote locations. Communications between unit and headquarters is vital in order to track operations and report on progress; thus demanding the voice clarity to ensure operators are heard loud and clear.
Current VHF and UHF tactical communications solutions are often out of range and lose coverage in black spots, while satellite solutions do not guarantee coverage and come with a high recurring cost. In the past, organisations have been hesitant to adopt HF technology, because analogue HF radio transmissions lacked voice clarity, suffering from “hisses and crackles”, which meant that the operator needed to “listen hard” which was often impractical in noisy and stressful operations.
Your Codan Solution
Recent developments in software-defined radio (SDR) and HF optimised digital voice have eliminated the inherent clarity issues with analogue HF.
Digital voice technology overcomes the frequent poor voice quality that comes as a result of atmospheric effects and man made interference from other equipment and transmissions. Clear and intelligible HF communications is not only desirable, but can be vital when it comes to extremely critical situations. Codan Second Generation Digital voice TWELP vocoders bring a clarity that results in better communications and virtually eliminates the need for repeat calls, thereby increasing the efficiency and responsiveness.
- HF optimised digital voice eliminates inherent clarity and usage problems with analogue HF.
- Codan’s Second Generation TWELP Digital Voice provides a voice quality experience that is similar to cellular phones.
- Increased operating range and reliability, with reduced requirement to repeat messages.
- Reduced background noise and increase in the quality of speech reproduction.
Codan's digital voice technology sets new standards in HF voice communications with a significant upgrade from analogue, with improve voice intelligibility and reduced background noise.
Advances in digital voice technology, specifically Codan’s TWELP second-generation digital voice, provide an improved voice quality using the same bandwidth, giving an experience that is similar to cellular phones. This technology helps to reduce background noise and increase in the quality of speech reproduction, therefore increasing operating range and reliability, with reduced requirement to repeat messages.
