LoneWhisper®

The world’s most efficient satellite connectivity for IoT

LoneWhisper® is Lacuna’s proprietary satellite technology, designed to deliver small data messages from the world’s hardest-to-reach places — with ultra-low power consumption and long-term reliability. It allows sensor nodes to operate for years on a single battery, without need for mobile coverage or mains power.

Designed for the edge of the grid

Unlike traditional satellite systems, LoneWhisper® is purpose-built for:

  • Battery-powered devices
  • Small, infrequent messages (e.g. 30 bytes daily)
  • Remote and rural deployments
  • Low-cost scalability

At the heart of the system is a global relay network:

Ground nodes send data to satellites in low Earth orbit, which route it back to your dashboard from anywhere on the planet.

Smart Behind the Scenes

What makes LoneWhisper® truly special goes far beyond what you see.

Satellite forecast system
Our satellites actively broadcast pass timings to ground devices so they can wake only when needed.

LWiN® software
Each node runs our LoneWhisper® Intelligent Node (LWiN®) software automatically, which manages:

  • Sleep/wake cycles
  • Data buffering
  • Uplink timing
  • Frequency adaptation

Built on open standards

No need to be a LoRa® expert — LWiN® takes care of everything.

SEAMLESS INTEGRATION WITH LoRaWAN®

LoneWhisper® uses LR-FHSS, a low-power satellite adaptation of the widely used LoRa® protocol. It’s compatible with LoRaWAN sensors and designed to extend the reach of terrestrial LoRa networks — making integration simple for IoT developers.

Fifth-Generation Gateways

We’re now flying our fifth generation of satellite payloads —delivering the highest capacity LoRa-based gateway in orbit for Direct-to-Satellite IoT, which means:

  • More messages
  • More devices
  • Better resilience as the market grows

Smart Frequency Management

Lacuna has spectrum scanners on each of our satellites and these are used to map radio frequency usage and noise-levels around the world, since 2020. We use this valuable dataset to:

  • Dynamically adjust transmission channels
  • Avoid interference
  • Ensure future-proof spectrum operation

This background intelligence ensures LoneWhisper® continues to perform as the global demand for wireless communication grows.

A Decade in the Making

LoneWhisper® is the result of nearly ten years of R&D and over €20 million of investment, co-funded by the UK and European Space Agencies and private investors.

It’s not just technology: it’s trust, experience, and proven performance in orbit.

FAQs

What is LoneWhisper® and how does it work?

LoneWhisper® is Lacuna’s proprietary satellite network for IoT connectivity. It uses low-Earth orbit satellites to deliver small, low-power data messages from remote sensors — without needing mobile coverage or local infrastructure.

How is LoneWhisper® different from traditional satellite communication systems?

Unlike traditional satellite systems, LoneWhisper® is optimised for ultra-low-power devices and small, infrequent messages — making it ideal for battery-operated IoT sensors in remote or off-grid environments.

Can LoneWhisper® be used with LoRaWAN devices?

Yes. LoneWhisper® is built on open standards like LR-FHSS and is fully compatible with LoRaWAN sensors, allowing developers to extend the range of terrestrial LoRa networks with seamless satellite integration.

What types of IoT applications is LoneWhisper® best suited for?

LoneWhisper® is ideal for use cases like smart agriculture, utility metering, environmental monitoring, and asset tracking — where small data packets, long battery life, and global coverage are essential.

Is LoneWhisper® ready for large-scale commercial deployments?

Yes. With fifth-generation satellite payloads, smart frequency management, and over a decade of R&D, LoneWhisper® is a scalable, proven solution — already supporting thousands of connected devices worldwide.
