Wireless avionics intra-communications: Current trends and design issues

Wireless Connectivity in Airplanes: Challenges and the Case for UWB

“…Intra-aircraft developments are led by the wireless avionics intra-communications (WAIC) project, an initiative bringing together major aerospace companies like Airbus, Boeing, and Embraer [9]. The project wants to solve common issues associated with wireless communication between aircraft compo-nents, covering safety and general purpose applications (see examples in Table 1 and many more in the survey [8]). The dissimilar redundancy coming from the wireless deployment enhances the robustness to mechanical failure.…”

“…The use of multicarrier based technologies for implementing wireless intra-aircraft networks has also attracted significant attention (see [8] and reference therein). We argue that current energy harvesting techniques cannot power sensors based on these technologies.…”

Channel Measurement and Feasibility Test for Wireless Avionics Intra-Communications

“…Wireless technologies to enable communications outside an aircraft have been broadly investigated and developed to support various necessary functionalities such as aircraft-ground control, inter-aircraft communications, and radar. Contrary to this, applying wireless networks (e.g., intra-avionics sensor networks) inside the aircraft has been relatively less highlighted due to the concerns about wireless communication on reliability, safety, and security, compared to wired ones [2]. However, recent advances in wireless communication technologies show that mandatory operational-criteria (e.g., reliability and robustness) of the aircraft can be sufficiently satisfied through wireless networks, which results in the overall weight reduction of the aircraft (e.g., removing the wired cables) [3].…”

“…Raharya and Suryanegara investigated the compatibility of WAIC systems with radio altimeters at 4.2–4.4 GHz by simulations [6], and analyzed the modulation performance in the WAIC systems with consideration of various factors such as modulation efficiency, net average application data rate, and protocol overhead [7]. Sámano-Robles et al [2] investigated design issues in WAIC systems across several layers: from physical-layer to application layer. Park and Chang [8] proposed a mathematical framework to evaluate wireless protocol candidates in terms of the deadline missing probability and the packet loss probability.…”

HAMSTER healthy, mobility and security-based data communication architecture for unmanned systems

“…In the last few years, there has been a huge eagerness by the industry towards fly by wireless (STUDOR, 2007;GOMEZ, 2010;POOVENDRAN, 2013;SáMANO-ROBLES et al, 2016) and drive by wireless (KHAN, 2011; STÄHLE; HUANG; KNOLL, 2014). Due to that, the aerospace industry and technology providers were motivated to establish: i) a new emphasis for system engineering approaches to reduce cables and connectors, ii) provisions for modularity and accessibility in the vehicle architecture and iii) a set of technologies that support alternatives to wired connectivity.…”
