LoRa Mesh Radio Solutions

KANGLONG RADIO offers a field-proven LoRa Mesh communication system designed for total reliability in the most demanding environments. Our comprehensive solution integrates the D7000 Solar Repeater for permanent off-grid coverage, the D6000 Series (Fixed, Vehicle, and Portable D6000R units) for flexible network backbone, and high-power handhelds including the 8W D750 and the versatile D680, D600, and D380. Backed by years of market testing and our Quanzhou factory’s high standards, this system delivers a stable, professional-grade ad-hoc network with unmatched price-performance, ensuring your team stays connected where traditional infrastructure fails.

No Networks Required

How It Works

This is not just a walkie-talkie. It is a self-healing, highly adaptive, and deeply resilient wireless ecosystem.

• LRAN 1.0 Proprietary Protocol: Built upon the high-performance STM32F4 control platform and the SX1278 RF transceiver transceiver , devices instantly form a smart, localized Long Range Automatic Network (LRAN) within the UHF 400–510MHz band upon powering up.
• Every Node is a Repeater: Powered by advanced Ad-hoc decentralized networking , every mobile handheld, vehicle radio, and base station dynamically acts as both a transceiver and a relay.
• 30-Level Relay Jumping: Signals leap seamlessly from device to device up to 30 times, effortlessly routing voice around mountains, thick concrete structures, and severe terrain obstacles to eliminate dead zones.
• Intelligent Auto-Forwarding: The system intelligently measures signal quality using hardware-level RSSI (Received Signal Strength Indicator) and SNR (Signal-to-Noise Ratio) thresholds. If a direct signal is flawless, it refrains from repeating to optimize spectrum efficiency; the moment a signal weakens, the mesh automatically kicks in to pass the baton

Where It Shines

Where traditional telecom networks drop to zero bars, KANGLONG LoRa Mesh thrives.

• Subterranean & Industrial Hubs (Tunnels, Mining, Basements): Thick concrete walls and subterranean depths are notorious signal graveyards. The compact D380 and the high-power 8W IP68-rated D750 push deep into tunnels and underground shafts, allowing voice packets to bounce around bends and dense structures without interruption.
• Off-Grid Wilds & SAR (Emergency Firefighting, Mountain Rescue, Search Operations): When cellular networks collapse during natural disasters or vanish in dense forests, deploying the 18W D6000R portable repeater with its 10,000mAh independent battery creates an instant, secure emergency network spanning miles within seconds.
• Unattended, Remote Infrastructure (Wind Farms, Massive Agricultural Estates, Border Patrol): For permanent, completely infrastructure-free deployments, the maintenance-free D7000 solar-powered repeater uses a high-capacity 20Ah battery to run 365 days a year entirely off-grid.

The Uncompromising Benefits

Zero Subscription. Zero Fees. True Independence: Completely disconnected from cellular operators. No SIM cards, no monthly platform contracts, and zero ongoing data fees. You own 100% of your communication architecture.

• Absolute Resiliency (No Single Point of Failure): In standard radio systems, if the main repeater goes down, the team goes blind. In a KANGLONG LoRa Mesh network, if any device drops out, the remaining nodes automatically recalculate the next best path in milliseconds to keep the line alive.
• Targeted Dispatch (All, Group, or Individual Calls): Control exactly who hears what. Each of the 16 channels can be configured to broadcast to the entire network (All Call), a specific field team (Group Call), or a private 1-to-1 conversation (Individual Call)
• Instant Distress Protocols (SOS Emergency): Equipped with normal and silent SOS modes. Pressing and holding the SOS key for 3 seconds instantly triggers an automated alarm network-wide, notifying all connected units in real time.
• Pro-Grade Software Tailoring: Fully configurable via PC-based programming software (CPS). Administrators can personalize application headers , batch-export operational parameters to Excel , and calibrate channel frequencies to match highly specialized field parameters.
