Cellular technologies are the backbone of innovations in automotive Internet of Things (IoT) and smart mobility, powering everything from real-time diagnostics and navigation to advanced driver assistance systems (ADAS) and emergency response systems like eCall.
In India, the connected vehicle sector is set for substantial expansion, with forecasts suggesting a market volume of USD 32.5 billion this year, fuelled by rising uptake of advanced driver-assistance systems (ADAS) and government support. This expansion, driven by the integration of 5G connectivity and artificial intelligence (AI), is enabling capabilities such as cloud connectivity, multiple displays, and on-device generative AI (genAI).
As automakers and original equipment manufacturers (OEMs) adopt these technologies to address growing consumer expectations, managing highly connected vehicles at scale becomes increasingly complex.
The future of connected vehicles
One challenge OEMs are grappling with is the matter of handling vehicle data in real time. Frequent cellular connectivity lapses, fragmented network infrastructure, and growing cybersecurity vulnerabilities all disrupt real-time communication and data exchange, which risks vehicle safety, operational efficiency, and data privacy.
Overcoming these problems hinges on engineers, OEMs, marketers, and service providers each having access to various data streams, including telematics, location information, in-vehicle diagnostics, and user preferences. However, managing these requirements within a secure, scalable backend framework presents a considerable engineering difficulty.
At the same time, Indian consumers are demanding more from their in-car digital experiences. Features like eCall – which automatically contacts emergency services after a crash – are gaining traction for their safety benefits. Drivers also expect reliable infotainment, personalised services, and seamless smartphone integration. These functions all depend on continuous, high-speed cellular connectivity. However, adhering to country-specific telecom standards and eCall regulations adds another layer of complexity. Country-specific regulations make it challenging to deploy connected car services at scale while ensuring compliance and speed to market. Safeguarding the accuracy and privacy of vehicle communications is critical to maintaining trust. Any breach or data leak could compromise both user trust and safety. These security protocols and connectivity solutions must also have the flexibility to evolve with changing mobile network standards, as cars can typically remain on the road for up to 15 years.
Secure solutions for connected cars
India’s move toward connected mobility will continue to accelerate thanks to the rollout of 5G networks and edge computing throughout the country. These technologies significantly improve bandwidth and reduce latency, enabling real-time data exchange and faster decision-making within the vehicle ecosystem. For example, low-latency communication is essential for applications such as collision avoidance and real-time traffic updates.
Cellular connectivity also powers critical vehicle functions such as secure onboarding, over-the-air (OTA) updates, remote diagnostics, and centralized management of software and firmware. These critical systems must be protected by best-in-class security protocols, making security a top priority.
Key technology enablers for secure, scalable connected cars including eSIM (embedded SIM), Remote SIM Provisioning (RSP), and the IFPP (Integrated Factory Process for Personalization), are bringing new levels of flexibility and security to the automotive landscape. eSIM technology, for example, allows secure, remote management of SIM profiles without requiring physical access to the vehicle, making it easier for OEMs to switch between network operators, respond to regulatory changes, or update connectivity features throughout the car’s lifecycle.
Remote SIM Provisioning (RSP) enables seamless activation, updating, or changing of mobile network operator profiles over the air. This reduces the need for vehicle recalls or manual intervention, significantly lowering costs and downtime for OEMs while improving responsiveness to different market requirements.
IFPP streamlines the secure personalization and provisioning of connectivity modules during manufacturing, ensuring that vehicles are born securely connected and ready for compliant OTA management from day one.
Also, as the industry moves toward V2X (Vehicle-to-Everything) connectivity, vehicles are increasingly able to communicate not only with one another but also with infrastructure such as signals, signs, and even pedestrians’ devices. V2X communication further boosts road safety through real-time exchange of traffic and hazard data, enables smoother traffic flow, and lays the foundation for future autonomous driving features.
Thanks to these interconnected technologies, automakers can deliver vehicles ready for tomorrow’s mobility while meeting today’s demands for security, agility, and user-centric services.
Thankfully, advancements can be seen through innovations in encrypted SIMs, secure provisioning protocols, and tamper-proof cellular modules to protect vehicle data and maintain user trust. These measures help block unauthorized entry to critical systems and allow automakers to adhere to India’s data protection laws. To minimize fragmentation and guarantee uniform protection throughout the ecosystem, stakeholders should promote the establishment of universal security standards and strong compliance frameworks.
This involves advocating for complete encryption and strict verification methods. Investments should also be directed towards scalable connectivity solutions that are able to manage large volumes of real-time data transfer between vehicles and infrastructure.
Nonetheless, they also present new challenges, such as vast and more complex IoT networks, secure data exchanges, and changing regulatory demands. Thankfully, these challenges are being tackled head-on through solutions such as encrypted SIMs and secure provisioning that meet compliance standards to assist OEMs in creating vehicles prepared for the future.
As connected mobility continues to advance, the questions around security, scalability, and innovation are only becoming more urgent. But truly delivering safer, more efficient, and more intelligent connected transportation will depend on infrastructure that facilitates robust security frameworks, seamlessly integrates across ecosystems, and promotes long-term scalability.
