KA-160/450/500
DMR Tier 2 & Tier 3
KAIROS DMR Tier 2 & Tier 3 simulcast repeaters are the perfect platform for any DMR application, from simple standalone sites to large nationwide systems. Ideal for utilities, energy, education and manufacturing organizations, KAIROS Conventional/Trunked simulcast is a great fit for organizations that require wide area communications with limited frequencies.
Multi-protocol
- KAIROS repeater supports Analog, DMR Tier 2 & Tier 3, Paging (both Analog and POCSAG), and P25 Conventional protocols. Automatically switches between analog and digital modulation, according to the type of incoming signal.
IP Multisite Multicast & Simulcast
- Fully IP-based distributed network architecture supporting multi site, multi protocol network solutions in multicast or simulcast mode of operation.
- Provides RF backhaul among sites where the IP backbone is not available, carrying analog and digital signals. IP, UHF, and VHF links can be mixed in a single network.
RF Linking
- Supports flexible redundancy design as either 1+1 (Main + Standby) or with backup Primary functionality (a Secondary station that automatically replaces the failed main Primary, restoring all network functions).
System Redundancy
Soft Diversity Reception
- KAIROS soft diversity receiver technology allows for enhanced coverage and improved signal reception in RF fading conditions.
Powerful Remote Control
- The remote control tool also ensures secure software upgrades, diagnoses IP backbone issues, and continuously assesses the health of the entire radio system. KAIROS also integrates directly with 3rd party network management systems using the standard SNMP protocol.
Light and Ruggedized
- Compact and lightweight. Thanks to its environmental robustness, KAIROS can perform in harsh site conditions.
- KAIROS repeaters come standard with various reliability schemes including automatic protection schemes such as power range control, reverse polarity protection, peak and transient handling, soft start, current limiting and RF power limiting capabilities.
