Cytta Air integrates advanced communications technologies, including Wi-VHFi™ (marketed as Wi-Far™), whitespace spectrum architecture, a patented compact antenna system (U.S. Patent No. 8,823,599), and a Local Terrestrial Positioning Network (LTPN) to deliver a next-generation connectivity and positioning layer for autonomous systems, defense operations, and critical infrastructure.

Wi-Far provides a long-range, non-line-of-sight wireless infrastructure that enables secure, real-time communication and coordination across complex and degraded environments.

It is a resilient, adaptive communications backbone designed to operate in GPS-denied, GPS-degraded, and infrastructure-limited environments.
why now?

The rapid growth of autonomous systems, drones, robotics, AI-driven operations, and connected infrastructure is creating unprecedented demand for resilient communications and positioning technologies capable of operating beyond the limitations of traditional networks. Defense agencies, public safety organizations, industrial operators, utilities, transportation networks, and critical infrastructure providers increasingly require systems that can maintain reliable connectivity, coordination, and operational awareness across large geographic areas, remote locations, dense urban environments, and operationally challenging conditions. As connected systems become more autonomous and data driven, resilient communications infrastructure has become one of the most important strategic layers within modern operational ecosystems.

Wi-VHFi™ was developed to help address these evolving connectivity challenges through a long-range, non-line-of-sight communications architecture designed for both defense and civilian applications. By combining whitespace spectrum technologies, proprietary antenna systems, and Local Terrestrial Positioning Network (LTPN) capabilities, Wi-VHFi™ is designed to support resilient connectivity, positioning, and real-time operational coordination across autonomous systems, industrial operations, emergency response networks, smart infrastructure, transportation systems, and mission-critical environments where traditional communications infrastructure may be limited, congested, unreliable, or disrupted.

Features

Built for both defense and civilian applications, the platform combines:

– Advanced RF and whitespace spectrum utilization

– Patented compact antenna technology enabling extended range and deep signal penetration

– Mesh-enabled network architecture

– Autonomous system interoperability

– Local terrestrial positioning (LTPN) for GPS-independent operation

Cytta Air delivers:

– A resilient communications and positioning layer

– A dual-use infrastructure platform

– A spectrum control advantage

– A cost-disruptive alternative to legacy systems

The result is a scalable, infrastructure-light network capable of supporting mission-critical operations globally.
Core Capabilities
Non-Line-of-Sight Connectivity

Operates through buildings, terrain, forests, and dense urban environments.

Maintains reliable connectivity and operational coordination in environments where traditional line-of-sight communication systems are obstructed, unreliable, or unable to maintain stable performance.

Resilient Operational Performance

Designed for degraded, congested, contested, and challenging environments.

Helps maintain communications, coordination, and operational continuity during network disruptions, interference, electronic warfare conditions, or infrastructure outages.

Extended Range Coverage

Designed to operate beyond traditional Wi-Fi and wireless network limitations.

Supports wide-area operations, distributed autonomous systems, and long-range connectivity across large geographic regions without requiring dense infrastructure deployment.

Dynamic Spectrum Adaptation

Supports real-time spectrum allocation and intelligent network optimization.

Improves network efficiency, adaptability, and reliability by dynamically responding to changing environmental conditions and spectrum availability.

Infrastructure-Light Deployment

Reduces dependency on towers, fiber networks, or satellite infrastructure.

Enables faster deployment, lower infrastructure requirements, and greater operational flexibility across remote, temporary, mobile, or underserved environments.

Local Terrestrial Positioning Network

LTPN-enables positioning and coordination where GPS may be limited or unavailable.

Provides a resilient positioning and coordination layer for autonomous systems, connected operations, and mission-critical environments where GPS signals may be degraded or disrupted.
