Retevis Warehouse Radio Solutions

This professional warehouse radio system is engineered for facilities over 100,000 sq.ft. The complete kit includes a robust repeater, antennas, and all necessary accessories for immediate deployment. It eliminates communication dead zones, ensuring reliable, crystal-clear coverage throughout your entire operation to maximize efficiency and safety.

Warehouse Communication Challenges in Large Facilities

Modern warehouses are built with steel racks, reinforced concrete walls, and multi-level layouts. While these structures maximize storage density, they severely block and absorb radio signals.

Common communication issues include:

• Weak signals between aisles and high racks
• Dead zones near loading docks and corners
• Unreliable communication between indoor and outdoor areas

Traditional walkie-talkies alone cannot overcome these physical limitations.

Eliminate Dead Zones with a Repeater-Based Radio System

Retevis warehouse radio solutions are designed around a central repeater architecture, not point-to-point communication.

By deploying a high-power repeater and a distributed antenna system:

• Weak handheld signals are captured, amplified, and rebroadcast
• Coverage is evenly distributed across the entire warehouse
• Communication remains stable even in high-rack and metal-dense areas

This ensures every worker stays connected — from the loading dock to the farthest aisle.

Actual Working Principle of the Warehouse Radio Communication System:  

This system is designed to overcome signal loss caused by metal shelving and long distances by using a centralized repeater and distributed antennas. The communication process between A in the loading/unloading area and B in the high-rack warehouse.

① A transmits: A presses the PTT button on the walkie-talkie. Her signal weakens after passing through the metal shelving, but is received by the nearest ceiling antenna.

② Signal Transmission: The signal travels along the coaxial cable and eventually reaches the repeater.

③ Repeater Amplification: The signal enters the repeater (RT97P), which receives it, amplifies it significantly, and prepares it for retransmission.

④ Signal Redistribution: The strong new signal is retransmitted through the cable.

⑤ B Receives the Call: The signal is emitted from an antenna near B's location. His walkie-talkie receives a clear and strong call, as if A were standing right next to him. 

Clear Communication in Noisy, Fast-Paced Environments

Warehouses are loud. Forklifts, conveyors, and packing equipment make voice communication challenging.

Our system ensures:

• Strong signal strength at every working position
• Reduced voice dropouts and distortion
• Reliable communication without repeated calls

With consistent signal coverage, workers can communicate clearly without stopping their tasks or moving to “find signal”.

Seamless Coordination Across Loading, Storage, and Dispatch Areas

In daily operations, warehouse efficiency depends on fast coordination between:

• Loading/unloading teams
• High-rack storage staff
• Supervisors and dispatch

The repeater-based system allows:

• Instant group communication across zones
• Real-time task confirmation
• Faster response to operational changes

No switching networks. No delays. Just press-to-talk and respond.

Improved Safety and Emergency Response

Reliable communication is critical for warehouse safety.

With full-site radio coverage:

• Workers can call for help instantly from any location
• Supervisors receive emergency calls without delay
• Outdoor yards and indoor zones stay connected during incidents

Unlike Wi-Fi or cellular-based systems, the radio repeater system continues working independently of public networks.

Core of the Warehouse Radio System: Key Components

1. System Core: Repeater

Model: Retevis RT97L (Analog) / RT97P (Digital)

Function Introduction: The central hub and power source of the entire network.

Role: The repeater can be considered the control room of the system. It performs a key function called "full-duplex" communication:

It receives weak single-frequency signals from walkie-talkies.

It can instantly amplify the signal and retransmit it at higher power on different frequencies.

Key Features: High output power (25W), high gain, and support for multiple frequency bands make it ideal as the core of large-scale coverage.

2. System Components: Antenna Distribution System

This network is responsible for transmitting the strong signal from the repeaters throughout the facility.

① Coaxial Cable: Signal Transmission Conduit

What it is: A dedicated “cable” used to transmit RF signals.

Its Importance: Not all cables are created equal. High-quality, low-loss cables (such as 1/2-inch or 7/8-inch coaxial cables) are crucial to prevent excessive signal attenuation over long distances before reaching the antennas.

② Power Dividers and Couplers: Signal Directors

Models: Power Dividers, Couplers
Function: These passive components efficiently distribute and route signals.

Power Dividers: Distribute signals evenly across two, three, or four channels. Ideal for powering multiple antennas in areas with similar coverage.

③ Coupler:

A small, specific signal is diverted from the main line to feed branch lines (e.g., a single antenna in a corridor), while allowing most of the power to continue along the main line. 

3. Key System Components: Antennas

Model:Ceiling-Mounted Omnidirectional Antenna, Outdoor Omnidirectional Antenna

Function: Antennas are the final connection point of the system. They broadcast system signals into the air and receive signals from nearby walkie-talkies.

Choosing the Appropriate Antenna Type:
Omnidirectional Antenna: Radiates signals in all directions like a sphere. Ideal for open areas, low-ceilinged warehouses, and general wide-area coverage.

Directional Antenna: Focuses the signal into a specific beam like a flashlight. Essential for narrow spaces (e.g., conveyor belt tunnels, between high racks) or connecting different buildings.
