Executive Summary
This technical report explores the use of LoRa radios for Special Operations Forces (SOF) in environments with degraded or denied communications, aiming to reduce detectability. Through experimentation, it assesses LoRa's low probability of detection and its potential as a secure, low-cost communication alternative for tactical units. The findings suggest LoRa radios can enhance SOF operational security and communication resilience.
Why It Matters
This document is crucial for defense analysts as it evaluates a low-cost, low-detectability communication technology (LoRa) that could significantly enhance the operational security and resilience of Special Operations Forces in contested environments against peer adversaries. It directly addresses a critical vulnerability highlighted by recent conflicts, offering a practical solution for maintaining C2 while minimizing electromagnetic signatures.
Key Takeaways
- LoRa radio technology, especially with directional antennas and terrain masking, offers a low probability of detection, making SOF teams nearly invisible to adversaries.

This research provides an initial proof of concept that LoRa radios inherently bring a low probability of detection with directionality and terrain masking and can be nearly invisible to adversaries when used appropriately.
- Effective communication in electromagnetically contested environments is critical for SOF to transmit reconnaissance and targeting reports without revealing their presence.

To ensure that U.S. SOF teams can transmit reconnaissance and targeting reports up the kill chain, they must be proficient at securely communicating without revealing their presence to adversaries who are surveilling for them with state of the art equipment.
- Adopting inexpensive, commercial off-the-shelf (COTS) solutions like LoRa radios can provide a rapid and cost-effective way for the Department of Defense to improve SOF communication capabilities and reduce risk.

The adoption of inexpensive, low-power commercial solutions like LoRa is the clearest, fastest path for the Department of Defense to ensure its special operators can operate in the adversary’s electronic fog and maintain vital command and control.
Strategic Relevance
This research directly addresses the strategic imperative for Special Operations Forces to operate effectively and covertly in contested environments, particularly against peer competitors. By validating low-probability-of-detection communication methods, it contributes to maintaining tactical advantage, enhancing force protection, and ensuring critical command and control links in scenarios where traditional military communications are vulnerable.
