Infrastructure

The SDB680 DMR base station delivers 6.25 kHz equivalent digital communications at 50 Watt transmit power with 100% transmit duty cycle. Exploiting Simoco’s experience in radio infrastructure, SDB680 can be interconnected over an IP backhaul to form wide area radio systems without any additional or centralised switching components.

Benefits

• Full standards compliance ensures terminal supplier choice and avoids proprietary lock-in
• 50 Watt Transmit Power mitigates combiner losses and provides a like-for-like replacement when migrating to digital
• Continuous Duty cycle at full power for Tier III trunked radio systems and high availability Tier II radio networks
• Automatic analogue/DMR Tier II switching for seamless digital migration

The SB2025NT-T/N Simulcast Base Station offers market leading P25 performance in a robust, reliable yet compact 2U form factor. Designed and built to exceed industry standards, the SB2025NT-T/N is a spectrum efficient solution, perfectly suited to wide areas of coverage.

Building on the plug and play principles of analogue Dalman simulcast systems, SB2025NT-T/N integrated simulcast and voting controller offers enhanced resilience and full remote management of base station networks, while interfacing in a cost effective, compact component based P25 system.

SB2025NT Overview

• Simulcast technology synchronises duplicated channels in a wide area network to avoid interference between adjacent radio sites.
• Digital VoIP signals are better defined and more consistent than their analogue counterparts, enabling the synchronisation task to be ‘processor controlled’.
• SB2025NT-T/N incorporates an RSSI voter which can operate in talk through mode with simulcast transmit.
• Easy to deploy base station, with intuitive set up and simple remote management.

Solar 2 builds on the success of the Solar-Sync principles of a straight-forward plug & play Digital IP Simulcast and Voting solution, extending this capability to enable compact integration of Traffic Manager, Voter and Network Modules in a single 1U chassis together with full remote management and Traffic Manager resilience.

The system consists of Network Interface and Traffic Manager Modules, which can be selectively deployed in the 1U Chassis to achieve the desired network solution. The compact form factor and modular architecture means Solar 2 can be more effectively deployed in a small system desktop and larger network solution environments, where rack space is at a premium. Traffic Manager, at the heart of the system, provides voice routing, redundancy options and supervision, whilst fully duplex Network Interfaces provide connectivity of remote stations and dispatch consoles to the IP infrastructure.

Simoco Solar 25 is the latest ‘Dalman Inside’ simulcast product to be developed by our specialist simulcast engineers at Dalman Labs. Leveraging over 25 years of dedicated simulcast engineering, research and development, Solar 25 now extends the benefits of Dalman’s revolutionary simulcast over IP to the P25 environment.

Solar 25 Economics

Simulcast technology synchronises duplicated channels in a wide area network to avoid interference between adjacent radio sites. Solar 25 Digital VoIP signals are better defined and more consistent than their analogue counterparts, enabling the synchronisation task to be ‘processor controlled’.

This advantage revolutionises the economics of simulcast deployment and support; enabling automatic set up and remote management to replace specialist knowledge, costly test equipment and reduced on-site maintenance. Simoco Solar technologies extend the benefits of simulcast by removing traditional barriers of cost and technology complexity for customers.
