including telephone, microwave, data, vid-eo, satellite (such as OASIS), Internet, net-working, etc. This receiving technique is based on the vectorial treatment of two or more incoming signals. Soft diversity reducing the effect of multipath improves the audio quality and the effective RF coverage of the system. DMR RF Link TS B: Connection via RF-LINK on Time Slot B To connect Remote KAIROS via RF-LINK, please refer to Appendix 4.2. Standards compliant SIP allows for integration with VoIP phone systems. (6) Station ID: Uncheck for cable LAN connection. To connect Remote KAIROS via RF-LINK, please refer to Appendix 4.2. IP and narrowband RF linked professional infrastructure supporting: RTP is used for integration into IP dispatching systems.KAIROS Base Station/Repeater from Radio Activity (7) Use Secure Access Feature: Uncheck if first time use the KAIROS. KAIROS is a compact and rugged multi-protocol transceiver, based on a powerful LINUX core that allows a number of customized configurations: simple stand-alone repeater DMR TIER II and TIER III multi-site systems POCSAG and tunnel/in-building applications, thanks to the PTP1588 synchronization protocol. DMRMark, DMR Detection by Non-Homogeneous Hidden Markov Model from Methylation. KAIROS can manage two DMR timeslots, using a single antenna. KAIROS works perfectly in simulcast mode, supporting both IP and narrowband RF links among base stations. kairos, Analysis of Chronological Patterns from Archaeological Count Data. From a dispatching point, it can be configured to supply access to an external radio network. TS1 TS2 PC based radio dispatcher DMR - RF network access - Audio - Text Massages - GPS Positioning - Sel cal facilities - Comm.īy simply adding a duplexer, KAIROS can be configured as a standalone repeater. In addition to soft space diversity reception, it provides SIP/RTP-IP ports for dispatching and phone applications. 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.Ī DMR Tier 2 KAIROS based solution using Kenwood DMR hand-portable and mobile radios including the NX-5000 and NX-3000 Series equipment can be configured for both Multi-Frequency and Simulcast operation and supports multi-protocol (analogue/digital) functionality, IP-connected or conventional dispatcher and phone patching and SIP telephony.KAIROS is P.25 Phase 1 compatible is available in two versions (for horizontal/vertical mounting), and in the following frequency bands: 66-88MHz/136-174MHz/350-400MHz/400-470MHz/450-527MHz/841-961MHz.Ĭlick here to DOWNLOAD a brochure. Its LINUX core provides IP interfaces to other devices and networks and allows for a high level of customisation. The sophisticated software and hardware platform used in KAIROS makes it a powerful and robust Basestation or Repeater.

This method provides repeatability, the perfect matching of repeaters and can handle different protocols. KAIROS is an ETSI compliant multi-protocol repeater that implements all modulation/demodulation and filtering processes through algorithms in the Digital Signal Processor (DSP).
