FOTA is a mechanism that facilitates firmware upgrades over the air, in the background, in order to push new features and configuration changes responsible for controlling the underlying hardware. The ECU, capable of FOTA updates, communicates with the FOTA gateway, which is connected to the in-vehicle network. The Firmware Over The Air system consists of three components: a FOTA server that manages vehicle software releases; a FOTA client that communicates with the backend server; and a FOTA agent that performs run-time firmware upgrades.
It’s vital to be able to update the operating systems of linked assets in order to keep them safe, introduce new features, and correct errors. The Internet of Things (IoT) has a lot of potential, but it also comes with a lot of implementation challenges, including context-aware updates, connection concerns, security risk updates, IoT deployment scale issues, and recovery from interrupted updates. Firmware upgrades have become a standard component of IoT systems so that the massive number of connected devices remain updated and safe. Faststream has provided over-the-air (OTA) software updates for automobiles, medical devices, robotics, and more.
Today, automobiles have advanced to the point where they are incredibly clever. Instead of traditional mechanical components, the software now controls the majority of the vehicles. Software is becoming increasingly common in the automobile industry and accounts for a significant amount of the bill of materials. This rise, along with excessive warranty and recall costs, indicates that FOTA is inevitable.
Through OTA services, over the air firmware updates and downloads for any of the car’s electronic control components are possible. As the number of ECUs keeps increasing in vehicles, sharing diagnostic and operational data from onboard systems may assist automotive manufacturers in improving product quality and operational efficiency, as well as providing post-sale vehicle performance and feature updates.
Wireless upgrades should be possible in modern automobiles. A connected automobile that cannot be updated remotely poses a significant cyber security risk. Automotive over-the-air updates have become the most preferred method for the distribution of everything from operating system security patches to infotainment system features and configuration changes or ECU updates.
High demands are placed on the reliability and security of the processes used for the task of updating the critical vehicle functions. Service-oriented communication in the Adaptive AUTOSAR has replaced the signal-based communication used in the Classic AUTOSAR. This system architecture has made the integration of new applications into the entire system much easier. Therefore, adaptive AUTOSAR supports differential updates, while the classic AUTOSAR requires a full update of the application software.
Our Offerings
Our Management Server Includes:
Once the development of FOTA features for connected devices is done, the software and hardware components are exposed to the following pre-production test-case scenarios:
Low risks
FOTA (Firmware Over The Air) allows IoT manufacturers and distributors to configure devices long after they have been purchased. This allows them to stay updated on upcoming technological trends and emerging industry standards. This provides a flexible way to manage the product and mitigate potential risks.
Capability to penetrate the market
Every IoT device must be designed reliably and produced affordably. However, the capabilities of FOTA allow the manufacturer to conveniently iterate. This gives the engineers an easy time updating and coordinating every device.
Promotes Evolution
FOTA provides room for growth through regular updates and upgrades in line with changing trends and customer expectations, without which any IoT technology may become obsolete. Furthermore, FOTA has the advantage of speed over other IoT products such as Low Power Wide Area Network (LPWAN) and LoRaWAN, so new upgrades and installations can be done quickly.
Cost-Effective
The manufacturer can cut down on customer service and other operating expenditures by managing FOTA remotely. Effectively, this feature provides flexibility and convenience, thus saving the hassle of traveling on-site to fix bugs and other issues. The time saved on these excursions can be put to better use on other initiatives.
