SLR5500 Repeater 50W digital (DMR, VHF)

The Motorola SLR5500 50W Digital Repeater is a cutting-edge DMR (Digital Mobile Radio) solution optimized for VHF (136–174 MHz) frequencies, delivering reliable, high-quality voice and data communication for industries such as public safety, transportation, agriculture, and utilities. Part of Motorola’s MOTOTRBO portfolio, this repeater combines sleek design, robust performance, and advanced networking capabilities to provide expansive coverage and exceptional audio clarity.

Key Features

Compact and Energy-Efficient Design

The SLR5500 features a slim 1U, 19-inch rack-mount form factor (44 x 483 x 370 mm), perfect for space-constrained environments like control rooms or mobile setups. Its low thermal footprint and 40% reduced power consumption on standby lower operational costs. An integrated 3A battery charger and backup interface ensure continuous operation during power outages.

Superior DMR Performance

Supporting DMR Tier II and Tier III, the SLR5500 provides two simultaneous voice or data paths in digital TDMA mode, doubling capacity within a 12.5 kHz bandwidth. With adjustable RF output power (1–50W) and high receiver sensitivity, it ensures clear audio and extended coverage, even in rural or challenging environments. Digital error correction enhances voice reliability.

Seamless Analog-Digital Integration

The SLR5500 supports both analog (conventional or MPT 1327) and digital modes, with mixed-mode operation for compatibility with legacy analog radios. This enables a smooth transition to digital, protecting existing investments while leveraging the benefits of DMR, such as improved audio quality and data capabilities.

Scalable Networking Solutions

The SLR5500 supports multiple MOTOTRBO system configurations, including single-site conventional, IP Site Connect, Capacity Plus, Linked Capacity Plus, and Connect Plus, enabling flexible multi-site connectivity. Its IP interface facilitates integration with third-party applications and dispatch consoles, enhancing operational efficiency.

Unmatched Reliability and Security

Engineered for a 100% continuous duty cycle at 50W, the SLR5500 is validated through Motorola’s Accelerated Life Testing (ALT) for exceptional durability. It features AMBE+2™ vocoder for superior audio and supports advanced encryption for secure communications. Remote Diagnostics and Control (RDAC) enable real-time monitoring and management.

Future-Ready Technology

With 10x more processing power, 15x more memory, and 125x more data storage than first-generation repeaters, the SLR5500 is designed for future scalability. Its modular architecture, with field-replaceable power amplifier, power supply, and modem modules, simplifies maintenance and upgrades.
