PR900 Repeater 50W digital (Digital, DMR, VHF)

Description

The Caltta PR900 50W Digital Repeater is a high-performance DMR (Digital Mobile Radio) solution designed for VHF (136–174 MHz) frequencies, delivering robust and clear communication for businesses, public safety, municipalities, and industries like rail, airports, and oil & gas. This compact repeater combines advanced digital technology, seamless analog-to-digital integration, and flexible networking capabilities to ensure reliable coverage and enhanced user experience.

Key Features

Compact and User-Friendly Design

The PR900 features a space-saving 1U design, half the height of conventional repeaters, making it ideal for installations in tight spaces like control rooms or mobile setups. Its 2.0-inch HD color screen provides intuitive navigation, allowing users to monitor status and configure settings effortlessly.

Advanced DMR Technology

Supporting DMR Tier II and analog conventional modes, the PR900 uses two-slot TDMA technology, enabling two simultaneous voice or data calls within a 12.5 kHz bandwidth. Each slot occupies 6.25 kHz, reducing transmission time by 50% and extending radio battery life by up to 40%. This doubles capacity without additional equipment, optimizing efficiency.

Seamless Analog-Digital Integration

The PR900’s smart digital-analog auto-detection ensures compatibility with legacy analog radios, protecting existing investments while facilitating a smooth transition to digital. This makes it ideal for organizations upgrading their communication systems.

Flexible Networking Options

With IP site connect as standard, the PR900 supports multi-site networking for extended coverage. Features like Enhanced Conventional System (ECS) enable dynamic channel allocation, supporting up to 8 repeaters per site and 32 sites over IP. Simulcast and active link options provide large-scale coverage with fixed frequencies, ideal for widely distributed users.

Enhanced Audio and Security

Digital voice processing minimizes environmental noise, ensuring clear calls in noisy or complex environments. The PR900 supports professional encryption algorithms, authentication, and remote stun features to secure data and ensure system reliability.

Comprehensive Functionality

Beyond basic PTT services, the PR900 supports text messaging, status updates, map-based location services, and call recording, enriching operational capabilities. It integrates with third-party dispatchers via the AIS protocol for seamless communication across sites.
