Covert Communications

• Reduces geolocation exposure by increasing uncertainty in network-based device location estimates
• Supports commercial 4G/5G connectivity without requiring a trusted or purpose-built network
• Enables data exchange while helping protect user position in contested or sensitive areas
• Degrades triangulation accuracy from network-side localization methods
• Supports tactical mobility across untrusted wireless environments
• Designed for future integration into tactical devices, deployable communications kits, and mission-specific wireless systems

• Special operations and forward-deployed teams
• Covert and clandestine communications
• Untrusted or compromised cellular environments
• Tactical messaging, telemetry, and coordination
• Border, infrastructure, and remote-area operations
• Missions where connectivity is required but location exposure creates operational risk

Tiami’s current LPG solution is an obfuscating retransmission device designed for 4G/5G cellular networks, including terrestrial cellular and nonterrestrial cellular environments. It manipulates device transmit beams and RF parameters to reduce the accuracy of network-side geolocation.

The approach is designed to preserve connectivity while increasing uncertainty around the user’s true location. Rather than promising invisibility or attempting to remove the device from the network, LPG makes accurate localization more difficult for network-side methods that rely on device signal characteristics and triangulation.

The capability can be extended to Wi-Fi networks relatively quickly. It is not currently designed for proprietary SATCOM waveforms, and older 2G/3G waveforms are not a current test focus due to phaseout in the United States.

In Tiami testing, standard network-side device localization produced an estimated location region of approximately 1,200 square meters. When the device utilized Tiami’s LPG countermeasure, the estimated location region increased to approximately 20,000 square meters.

This increase in localization uncertainty demonstrates the core objective of LPG: preserve communications while reducing confidence in the user’s true position.
