KENWOOD KAIROS Multi-Protocol Repeater

KAIROS is an ETSI compliant multi-protocol repeater that implements all modulation/demodulation and filtering processes through algorithms in the Digital Signal Processor (DSP).

This method provides repeatability, the perfect matching of repeaters and can handle different protocols. The Kairos repeater offers true multi-protocol flexibility as the addition of a new protocol or standard can be achieved with a software upgrade.The sophisticated software and hardware platform used in KAIROS makes it a powerful and robust Base station or Repeater. Its LINUX core provides IP interfaces to other devices and networks and allows for a high level of customisation.

KAIROS is designed for infrastructure applications, especially where radio frequency pollution is an issue and offers excellent coverage and clear communications with rejection of adjacent channel interference.

kairos-key-features-1

Multi-protocol

It performs the automatic switching between analog and digital modulation, according to the type of incoming signal.

IP multisite multicast and simulcast

It integrates all the necessary algorithms (such as, IP interfaces, voting system, automatic equalization, protocol coherence, synchronization recovery, network managing, etc.) to realize professional multisite networks.

UHF linking

It provides RF interconnections among sites where the IP backbone is not available, carrying analog and digital signals. It is a mixed linking network (IP+UHF).

System redundancy

It can be assembled as 1+1 (Main + Stand-by) and it can support the backup Master functionality (a Slave station that automatically replaces the failed main Master, restoring all network functions). Its LINUX platform allows a distributed elaboration in the system, thus increasing its flexibility and reliability.

Soft diversity reception

It is a receiving technique based on the vectorial treatment of two or more incoming signals. It strongly enhances the covering range and the clearness of a digital mobile communication system, removing fading holes.

SIP/RTP-IP ports

This direct connection with the radio network offers a wide range of benefits to Control Rooms, such as SIP/RTP-IP dispatching systems; automatic roaming between different networks and/or repeaters (mobility); automatic phone/radio bridging, etc.

Powerful remote control

Thanks to its remote detailed monitoring and configuration tool, setup and network maintenance operations are simplified and sped up. The remote control tool also ensures secure software upgrades, IP backbone diagnosis and a continuous assessment of the entire radio system. KAIROS also supports the SNMP protocol for direct reporting to a generic surveillance system.

Light and ruggedized

It sports a very compact size and weight. Thanks to its environmental robustness, KAIROS can perform in uncomfortable sites, and thanks to its low power consumption, it is considered a “green” solution, as it can be powered simply by a small solar panel.

Reliable

The power supply input is protected from short circuit, under/over/inversion voltage and transient. Its RF power devices are protected from reverse power, over temperature and over current, allowing a 100% duty cycle.

KENWOOD KAIROS: Key applications

kairos-multi-site-simulcast-multi-frequency

Multisite Simulcast or Multi-frequency DMR TIER III Trunking System

The TIER III Controller can manage a group of IP-linked networks, thus realizing a multisite, multicarrier (simulcast or multi-frequency) system.

kairos-simulcast-or-multi-frequency-ip-link

Analog and DMR Tier II Simulcast or Multi-frequency IP-linked Base Station

KAIROS supports IP connections among base stations to achieve multisite hierarchical systems. The role of a device can be set as Master, Secondary Master, Slave or Backup Master. A Master manages up to 32 Slaves/Secondary Masters, allowing unlimited expansion of a radio network.

kairos-rf-linked-base-station

Analog and DMR Tier II Simulcast or Multi-frequency RF-linked Base Station

KAIROS can be configured as a “LAN extender” supporting the RF narrowband connection among different sites. It is the perfect solution when the connecting distance is very large, or when the radio link path is not in line of sight.

kairos-dmr-single-site-tier-iii

Single site DMR TIER III Trunking System

With a built-in SW Agent Tier III Controller, channels can be efficiently shared among all users, according to the ETSI standard Tier III Trunking protocol. No additional HW is needed for small and medium size systems. An external TSC needs to be added only to large and complex networks.

kairos-dual-timeslots-fixed-station-repeater

Dual Timeslots Fixed Station/Repeater

KAIROS can manage two DMR timeslots, using a single antenna. From a dispatching point, it can be configured to supply access to an external radio network. By simply adding a duplexer, KAIROS can be configured as a standalone repeater.
