COVID-19 IMPACT

Data Bus Market Had a Negative Effect Due to Supply Chain Disruption During COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The COVID-19 pandemic adversely affected the data bus market share, mainly because of the manufacturing disruptions, supply chain restrictions, and delays in project execution in the main markets of data bus including aerospace, defense, and automotive. The slowdown of air traffic around the world caused aircraft production to decrease and installation of new avionics systems to be postponed which had a direct impact on the demand of data bus systems such as ARINC and MIL-STD-1553. On the same note, cancellation of vehicle production as well as reduced consumer demand of automobiles undermined installation of CAN bus systems. Delays in the procurement and testing of bus hardware components, including connectors, cables, and network interfaces were also due to lockdowns and shortages in workforce. There was a sluggish approval of funding to the defense programs and delayed modernization programs, further reducing the growth in the market. There were also supply chain limitations by logistical difficulties and higher costs of electronic components. The recovery in the market was experienced as restrictions were softened, but the immediate effect pointed at the weakness in the production and focused on the necessity to be more digital and employ diversified sourcing strategies.

LATEST TRENDS

Adoption of Ethernet-Based and High-Speed Data Bus Architectures Drives Market Growth

One of the biggest trends in the data bus market is the increased adoption of Ethernet based and high-speed bus architectures in aerospace, automotive and defense industry. Time-tested data bus specifications like ARINC 429 and MIL-STD-1553 are limited in their bandwidth by current applications that require high data rates. With the development of the systems that may combine enhanced sensors, real-time analytics, and autonomous functionality, the necessity of augmented data transfer and scalable connectivity is growing. Standards like ARINC 664 (AFDX) are based on Ethernet, and are full-duplex, deterministic with support for multiple nodes, which is why they are best suited to next generation aircraft and cars. Ethernet buses are substituting traditional CAN systems in the automotive industry to enable the functionality of ADAS, infotainment, and autonomous driving. On the same note, military and ship systems are moving towards switched network architecture to achieve high-speed, highly-secure communication. This move to Ethernet-based systems is part of a wider transformation to standardized high-performance data communications networks with the capability of supporting the increasing complexity of interconnected and intelligent systems.
