This project examined the use of sensors with embedded or augmented RF capability, and the mechanism of integrating these sensors within other components and subsystems.
Researchers conducted investigations concentrating on the needs of the aerospace community with particular attention to data integrity and latency. The investigation considered major obstacles of deploying wireless sensors on aircraft to support level E,D,C,B and A system certification needs.
To accumulate data on channel characterization on potential wireless sensor link paths and assess feasibility of this technology, researchers
- Evaluated the current aircraft RF certification process.
- Evaluated the RTCA SC 202 working group and draft D0-294 T-PEDS status as extensible to wireless sensors.
- Evaluated European work in this area.
- Evaluated suitability of the ISM bands with respect to compatibility with networks and coexistence.
- Evaluated possible alternatives to the ISM bands for improved performance.
- Determined the need for encryption. (FIPS/AES/other)
- Coordinated with the FAA to define next steps and or work needed to fill holes/gaps.
- Collected and evaluated existing Channel Modeling work (NASA, Boeing, AVSI, others) to determine whether further channel characterization data should be collected and shared
