Wireless Sensing - the Road to Future Digital Avionics

A look at the comparative performance of wired and wireless sensors, type of wireless sensors & interfaces, frequency performance, protocols, network topologies, and qualification standards.

The performance of avionics systems is dictated by the timely availability and usage of critical health parameters. Various sensors acquire and communicate the desired parameters. In current scenarios, sensors are hardwired and the number of sensors are growing due to automation, which increases the accuracy of intended aircraft functions.

Sensors are distributed all over the aircraft and they are connected through wired networks for signal processing and communication. Line-replaceable units (LRUs) that integrate various sensors also use a wired approach for communication.
