Motorola MOTOTRBO SLR 5500 VHF Repeater the Next-Generation Connectivity

Motorola MOTOTRBO SLR 5500 Repeater is a next-generation communication device designed to provide high-performance, high-reliability two-way radio service, serving as the cornerstone of a professional MOTOTRBO digital radio system. It is engineered for both the simplicity of a single-site conventional system and the powerful capabilities of advanced trunking architectures.

SLR 5500 Flawless VHF Coverage, Engineered for All-Day Operation.

Models like the DR3000 set the foundation; as a result, the SLR 5500 represents a significant leap forward in succeeding repeater technology.

Saving valuable physical space, the Slim and Compact Form Factor features a space-efficient 1U height (1.75 inches / 44mm) perfect for rack or wall-mounted installation.

High Power Efficiency: Utilizing the latest RF technology, the repeater has a very low thermal footprint and reduced power consumption, which is up to 40% less in standby mode than previous models.

Continuous Operation: The unit is designed for round-the-clock reliability with a 100% duty cycle at its full transmit power of 50W.

Ease of Service: The modular architecture includes Field-Replaceable Units (FRUs) for the Power Amplifier, Power Supply, and Modem modules, which simplifies maintenance and reduces downtime.

Performance and System Capabilities

• Frequency and Power:

  • It supports VHF (136–174 MHz) frequency bands.

  • It offers a flexible and powerful RF Output Power of 1–50 W.

• Dual-Mode Capability: It can operate in Analog Conventional, MOTOTRBO Digital (DMR Tier II), or Mixed Mode, facilitating a smooth transition from legacy analog systems to a digital platform.

• System Compatibility: It is compatible with the full suite of MOTOTRBO system architectures, allowing for flexible network scalability and coverage extension:

  • Digital Conventional

  • IP Site Connect (Multi-site coverage extension)

  • Capacity Plus (Single-site dynamic trunking)

  • Linked Capacity Plus (Multi-site dynamic trunking)

  • Capacity Max (Flagship DMR Tier III solution for large, scalable systems)

  • Connect Plus (Wide-area trunking)

  • It also supports the MPT 1327 analog trunking protocol.

• Digital Advantages: When operating in digital mode, it delivers two simultaneous voice paths in a single 12.5 kHz channel using Time-Division Multiple-Access (TDMA), effectively doubling channel capacity. It also provides clear voice quality due to next-generation receiver design and digital error correction.

Applications

The SLR 5500 is ideal for any organization requiring expanded and reliable two-way radio coverage, including:

• Manufacturing and Industrial Sites

• Hospitals and Healthcare Facilities

• Energy and Utility Operations

• Government and Public Safety

• Transportation and Logistics

The Motorola SLR 5500 Repeater is an essential component for extending the range and boosting the capacity of your MOTOTRBO radio system.
