With over 25 years of experience, OST is a trusted partner in managing complex RF environments through end-to-end solutions from interference mitigation, frequency coordination, and advanced modeling to supporting mission-critical communications for federal agencies, defense, aviation, and public safety organizations.
Our engineers and analysts design solutions that enable real-time spectrum monitoring, predictive modeling, and cybersecure decision-making—ensuring mission success across today’s most congested and contested electromagnetic environments through AI-driven automation and IT modernization solutions that ensure optimal use of radio frequencies, interference-free communications, and seamless policy compliance.
The Need for Smarter Spectrum Engineering
- Growing demand from 5G, Unmanned Aircraft Systems (UAS), and defense creates spectrum congestion
- Legacy spectrum tools delay assignments and limit coordination
- Electromagnetic Interference (EMI) & Security Risks disrupt aviation, defense, and emergency response communications
- Manual workflows hinder compliance with NTIA, DoD, and FCC agency mandates
- Agencies lack simulation tools for next-gen spectrum planning (AI, IoT, autonomous systems)
A Powerful Combination
OST’s RF Spectrum Engineering solutions combine intelligent automation, predictive analytics, and real-time decision support to help federal and state agencies plan, protect, and modernize their use of the electromagnetic spectrum to secure mission success today and into the future. With over 25 years of mission-proven federal experience across national security, aviation safety, defense operations, emergency response, and modern telecommunications, OST is the go-to partner for RF Spectrum Engineering solutions.
CASE STUDY:
Securing the Skies: Advanced RF Spectrum Engineering for FAA Safety and National Security
Challenge
The FAA faced the complex challenge of protecting its interference-free radio frequencies, an increasingly vital resource amidst rapidly increasing demand for wireless technologies and the ever-present threat of interference to the National Airspace System (NAS).
The core challenge is maintaining clear and reliable radio frequencies for all civil aviation systems while the proliferation of wireless applications intensifies the complexity of managing spectrum use, requiring robust protection against interference and unauthorized broadcasts to safeguard NAS operations.
Solution
OST supported the FAA to secure, manage, and protect aviation spectrum through advanced RF Spectrum Engineering and dedicated defensive spectrum operations by employing sophisticated automation systems and tools for frequency assignment, analysis, and interference mitigation.
A critical aspect of our solution involved close coordination and data exchange with other government agencies, leveraging tools like Spectrum XXI Online and advanced engineering modeling for various aviation systems, including RFI mitigation engineering in multiband frequency domains.
Outcome
OST defined the business process for spectrum coordination with FAA for all the IRAC agencies and rolled out Web Frequency-Coordination Request IT system that reduced the coordination time by 50%, allowing FAA and agencies to have clear and transparent communications and updates about the coordination requests. Support for information systems security and continuity of operations further enhances the resilience and security of spectrum-related services.
Through advanced RF Spectrum Engineering and proactive defensive spectrum operations, we helped the FAA successfully ensure the integrity, availability, and reliability of the radio frequency spectrum critical for air transportation safety and national security.
