LR2021-based EW-resilient communication modules

RX, TX and custom relay boards built around our proprietary LR2021-based communication technology.


We are not building another ecosystem. We focus on one critical component: an EW-resilient communication module that UAV and UGV manufacturers can integrate into their existing platforms.

Extended RF operating range

Enables wider RF bandwidth options for improved communication resilience.

Improved receiver sensitivity

Supports more reliable communication over longer distances and under degraded RF conditions.

Packet recovery and error correction

Improves recovery from interference, RF noise and disrupted packets.

Optimized FHSS

Optimized frequency-hopping behavior for improved synchronization-channel resilience.

Anti-desynchronization

Improvements designed to reduce communication failures caused by interference.

Anti-unbinding

Improved link robustness under contested electromagnetic conditions.

Competitive advantage

Built for contested electromagnetic environments

DroneLab combines modern RF hardware and proprietary firmware to provide a more resilient communication link while remaining easy to integrate into existing UAV platforms.

FEATURE
DRONELAB
STANDARD FPV SYSTEMS
EW resilience
Designed for operation in contested electromagnetic environments. Field validation in EW conditions in progress.
Performance depends heavily on RF configuration, operator experience and platform implementation. New pilots lose 75% of drones to EW.
Setup complexity
Simplified setup with firmware-based configuration and automatic binding.
Manual TX/RX configuration is often required.
Training requirement
Designed to minimize setup and configuration requirements.
Higher dependence on operator knowledge and RF configuration skills.
Integration
Drop-in integration designed for existing UAV platforms.
Integration requirements depend on the manufacturer and communication ecosystem.
RF platform
Semtech LR2021-based communication platform.
Typically based on previous-generation RF solutions.
Anti-interference features
Optimized FHSS, packet recovery, error correction, improved synchronization and link robustness.
Capabilities depend on the specific communication system and implementation.
Pricing
RX modules from €40
TX modules from €100
Varies by manufacturer and configuration.
Field experience

Developed with operational feedback

Our communication modules are being developed in collaboration with UAV operators and engineers, tested in the field, and deployed across numerous UAV platforms. This experience directly influenced the new LR2021-based modules.
