In 2008 KENWOOD introduced the NEXEDGE® range of advanced digital radios using the NXDN™ protocol, a widely supported open standard. NEXEDGE® was the first system of its kind with the ability to communicate with both analog and digital handsets, providing a cost-effective solution to customers migrating from legacy analog systems. As well as wider coverage, it is able to deliver clear voice quality, even in the noisiest of environments.
