A flexible software platform for connected vehicle applications

Accelerate and simplify your application development

All Rolling Wireless Network Access Devices (NADs) are delivered with an ultra-flexible NAD Software Platform (NSP), running on the NAD application processor. The NSP is designed to optimize the connected vehicle application development process, and allows you to speed up development while reducing development costs.

The platform offers a robust foundation for telematics and connected vehicle applications and services, supporting rapid development on a continuously updated operating system. It includes connectivity plus all the other components needed to build safe, reliable, and scalable automotive telematics applications.

Rolling Wireless provides end-to-end support to enable fast and simple development of your applications on the NAD. 

Tailored to your needs

Customizable Linux distribution

Optimize the Linux kernel and manage your features

The Rolling Wireless NAD Software Platform is based on a custom open-source Linux distribution, designed to provide up-to-date security and optimum performance throughout its lifecycle.

The custom configuration allows us to control the maintenance of the distribution and proactively update key software components. Our streamlined system maintenance strategy ensures an always up-to-date system, with planned upgrades of kernel and Yocto versions.

Highly customizable, the Linux distribution also allows you to further modify the kernel and easily add or remove features to meet your specific needs. For example, you can integrate external components to extend features, or to optimize system performance for improved bootup time or memory utilization.

Secure multi-application management

Select, enable and embed the services your application development project requires

The Rolling Wireless NAD software platform enables multi-application management in a safe and secure environment. It also provides access to multiple services and functions through C/C++ APIs, facilitating the development of automotive applications such as 

  • eCall 
  • Positioning 
  • Connectivity management 
  • Software updates 
  • Network monitoring 
  • and many more

Its rich set of core services includes:

  • Hypervisor integration and VM lifecycle management
  • Secure, advanced and highly flexible InterProcess Communication (IPC)/Remote Procedure Call (RPC) 
  • Trusted Execution Environment (hardware) integrated OpenSSL 
  • Configuration persistence framework
  • Clock management & time housekeeping
  • Integrate ALSA library for easier audio/voice projects enabling e.g. PulseAudio etc.

Advanced security features

Ensure compliance with advanced security features

The Rolling Wireless NAD software platform offers a secure environment with a fully secure boot sequence including signature checks, anti-fallback mechanisms and authentication checks (DM-Verity) at each level of the boot if required.

The platform provides security solutions for many possible threats and vulnerabilities of the system, including those defined by the UNECE WP.29 regulatory forum, by enabling secure components for access control (SELinux) and system monitoring and checking (IMA). It also offers security and crypto services like secure storage, OpenSSL engine, and others.

Rolling Wireless adheres to a strict vulnerability management process (tracking, reporting, analysing). We also continuously monitor and update key Linux security components.

Embedded software:

  • Secure Boot with signed images
  • Dual System with recovery mechanism
  • System security & integrity: SELinux, DM-Verity, IMA
  • Security/crypto services: Secure storage, Key storage, eFuses, OpenSSL engine (based on TZ/QSEE)
  • Hardware IP Acceleration (IPA) for firewall, filtering, routing, …

Security management processes:

  • Vulnerability Management System: Tracking/reporting of vulnerabilities (CVE, bulletins, RW inspections, …)
  • Continuous monitoring and update of key security Linux components (OpenSSL, iptables, …)

Reliability features and safe boot

The Rolling Wireless software platform includes a Dual System for backups and software updates, which ensures a reliable and safe boot every time. Its reliability features enable thermal management, power failures monitoring to prevent Flash memory corruption and memory management (e.g., fail-safe filesystems, wear-levelling/memory scrub, backup/restore …).


  • To ensure optimum reliability, Dual System is an important component of the NAD architecture
    • The Dual System uses two separate partition sets. The two sets have identical content during normal operation, but different content during software updates
    • The images that are loaded from one partition set and executed in the RAM are called the active system
    • The other set is referred to as a backup system (at run time) or update system (at software update time)
  • Rolling Wireless NADs support secure APIs (such as SWAP and SYNC) to allow necessary system level controls via customer applications

Over-the-air update

The platform comes with a pre-integrated market reference SOTA/FOTA solution. It also has all the necessary interfaces and utilities for integrating a custom SOTA/FOTA solution, including managing the dual system during OTA updates.

Software development and maintenance services

All Rolling Wireless software releases are thoroughly tested in a standard environment and configuration.

To ensure a high level of reliability for customer applications, Rolling Wireless offers a wide range of professional software development and maintenance services:

  • Support for development and configuration of the Rolling Wireless software solution within the customer application environment
  • Issue analysis and fixes for open-source Linux components in the customer application environment
  • Development of any custom features, functions and APIs required
  • Customer-specific maintenance during the entire project lifecycle
