LiFi Technology
Secure, Wireless Connectivity
Fairwinds is proud to offer next-generation LiFi (Light Fidelity) solutions — a transformative communication technology that uses infrared light instead of radio frequency (RF) to transmit data. Designed specifically for defense, national security, and RF-sensitive operations, our LiFi systems provide ultra-secure, high-speed wireless communication without compromising mission integrity.
What Is LiFi?
LiFi is a wireless communication technology analogous to WiFI, except LiFi replaces the disadvantages of radio frequency (RF) medium with the added benefits of a near infrared (IR) light medium. LiFi uses modulated LED light to transmit data between devices. The result: a secure, interference-free, and localized data network.
Why LiFi?
Unlike RF, LiFi is virtually undetectable
- Ideal for use in RF-sensitive or RF-denied environments (HERP/ HERF)
- Low Probability of Intercept/Low Probability of Detection (LPI/LPD)
- Exempt from spectrum coordination (no NTIA SPS or ASMO/AFSMO J/F-12) required
- Low-SWAP vice cable infrastructure
LiFi can coexist with — or replace — traditional wireless networks in tactical or strategic operations where signal control and infrastructure security are paramount.
Why Terra Ferma LiFi?
Terra Ferma LiFi systems are engineered to meet MIL SPEC standards and rigorous operational demands in defense environments.
Key capabilities include:
- ITU physical layer and MACsec architecture (NIAP Compliant)
- Terra Ferma LiFi is uniquely enterprise class
- Centrally managed via NSA compliant LiFiManager
- Scales from one to hundreds of Controller/APs
- Supports roaming anywhere in the network
- Cross-Domain ready with NSA MACsec
Use Cases
1) Strategic installation
- Enable secure communications in RF-restricted command centers, SCIFs, and hardened military installations (Example: fixed classified facilities)
2) Hotelling
- Establishing a SCIF level communications infrastructure in a temporary surrounding (an untrusted environment)
3) SCIFs*
- Ideal solution to enable wireless/tetherless connectivity in SCIFs. Eliminates need for faraday cage shielding.

4) Cybersecurity-Enhanced Networks
- Deploy LiFi as an air-gapped networking layer, invisible to conventional scanning or interception tools. LiFi is non-detectable, non-hackable, and non-jammable, unless an adversary is inside the signal footprint.
5) Expeditionary Communications
- LPI/LPD and secure wireless solution in tents and vehicles on the tactical edge
6) Space wire replacement applications
- Payload-saving cable replacement on satellites and rockets
