JVCKENWOOD expands its Digital Mobile Radio (DMR) offering with KENWOOD KAIROS DMR Tier 3 infrastructure. KAIROS technology enables unique and flexible system designs leveraging distributed IP-based DMR capabilities including simulcast, multicast and multisite functionality. KAIROS is the perfect platform for any DMR application

John North, JVCKENWOOD Vice-President of Enterprise Sales, says, “Our DMR solutions enhance our ability to design systems to fit the customer’s needs, spectrum resources, and capacity requirements. Simulcast and multicast trunking make KAIROS an ideal solution for utilities, education, energy and business, and industry organizations for wide-area coverage.”


IP Multicast/Simulcast and Multi-Protocol

With real time voting selection, KAIROS automatically switches between analog and digital modulation, according to the type of signal so you never miss a call. KAIROS repeaters support analog, DMR Tier 2 & Tier 3, Paging (both Analog and POCSAG), and P25 Conventional protocols.


KAIROS repeaters built with SDR technology are software upgradeable to multicast or simulcast Tier 3 multi-site capability, thus realizing a multi-site, multicarrier (simulcast or multi-frequency) system.

Resilient Design

With no central core, KAIROS systems can be designed with a 1+1 hot standby (main and stand-by) mode with backup primary functionality across a multi-site network design to provide advanced system redundancy that enhances flexibility and reliability.


Compact and lightweight, KAIROS can be powered simply by a small solar panel with low power consumption. Due to its environmental robustness, KAIROS performs flawlessly in even the harshest site conditions. 

KENWOOD KAIROS DMR Tier 2 and 3 infrastructure solutions are compatible with KENWOOD radios and dispatch consoles to keep your teams connected so you can get your job done safely and efficiently.
