Radiokupol

The Radiocupol+ consists of two parts – digital and analogue

shema

The digital part consists of three different kinds of DR-25 repeaters supporting either APCO 25 Phase I Conventional, dPMR Layer 2 or DMR Tier 2 digital standards. Changing from one standard to another can be done remotely by entering a special code. Different standards interconnect is done using a special IP-device called DVC-xxx where xxx stands for corresponding standard. Changing DVC standard can be done as well – special engineering qualification of local distributor is necessary. DVC also provides full compatibility with analogue part of the system.

The analogue part of the system makes use of RoIP gateways, application-oriented software developed by our company and two modifications of IP-consoles, specially designed after our vast experience with installation in small Russian police dispatch centers.
The development is based on a 20-year experience in solving specific radio communication tasks, as well as on the investigation into the world experience and equipment including that in the laboratory.

RoIP (Radio-over-IP) gateways connect to practically any radio, digitizes all the audio signals received from the radio (two throughput COM-ports are available as well) and sends the received packets to an IP-network. The application-oriented software, depending on the purpose, processes these packets at the output, and using the same base stations (repeaters) and dispatcher software (as well as KD-0x IP-consoles) including those operating on RoIP (Radio-over-IP) protocol, integrates users into a single communication network.

The entire software is based on Java which makes the hardware and system configuration flexible.
