Kairos Multi-protocol Soft DSP Radio Dual-mode Digital/Analog & IP Net

KAIROS is a multi-protocol transceiver/repeater that implements all mod-demodulation and filtering processes via Software by a DSP (Digital Signal Processor), following the “soft radio” concept. Dual-mode analog and digital modulation – IP Multicast & Simulcast – Soft Diversity vectorial treatment of two or more incoming signals – RF linking in DMR and analogue modes – SIP and AMBE +2 Gateway & SIP/RTP-IP network for wide range applications & utilityes!

Radio-Activity-Kairos-rear-1

It allows to manage multiple protocols at the same time to perform, for es., a dual mode in real time, according to the incoming radio (or IP) signals. (soft & hardware platforms is based on a Linux O.S. core). KAIROS Series ETSI / FCC  / CE certified – Designed and manufactured in Italy by  Radio Activity Srl – 20128 Milano IT.

Kairos-front-rear-combi

KAIROS, thanks to the “soft radio” designin, approaches this problem, with the same techniques adopted in the most diffused digital communication systems like GSM, GPRS, WiMAX, LTE etc. – It is equipped of 2 coherent indipendent receivers that, connecting then to 2 different antennas, realizes a “soft space diversity” reciving system. – When operates in digital, KAIROS manages the 4FSK modulation, it is the standard mod for DMR & P25, and can also manage, on request, the GMSK constellation and many generic FSK standards like the POCSAG groups.

built-in_Sig&Prot

The KAIROS rtx is dual mode analog/digital with the automatic switch between the Analog / DMR services. – The old FM rtx may operate with the new digital one through the same network.
KAIROS can run a “DMR Gateway” agent to interface Analog and DMR radio systems to several external networks. – The DMR Gateway Agent traslates Voice (full duplex audio stream from/to) and Data streams. (this runs in the Kairos engine without the need of external PC) [Note] (More info: …see the official data of Radio Activity pdf)

italiano Come si potrà leggere dal link qui sotto, IW7DZR, Giacomo e IW0RED, Marco dell’Associazione CISAR stanno già provando con test applicativi apparati KAIROS UHF nel campo radioamatoriale. – In digitale il DSP incorpora e gestisce mod-demod 4FSK per modi DMR e P25 e in dual-mode anche FM analogica – Kairos supporta reti Multicast e Simulcast per realizzare reti Multisite tipo professionale. – Il software fornito gestisce anche un ricevitore in “diversity” con due antenne per il trattamento vettoriale di più segnali in ricezione. – Fa parte del gruppo test anche Artem, R3ABM,  che ha elaborato il software CronosAgent  per applicarlo sotto BM (BrandMeister) !! Attendiamo altre news.
