2G, 3G, 4G Sunsets

Navigate the Transition: Strategic Planning for Network Evolution

As the transportation and automotive industry strides towards an increasingly connected future, the underlying mobile network infrastructure that powers vehicle connectivity is also evolving. The global rollout of 5G and the anticipated introduction of 6G are set to redefine what is possible in automotive technology.


However, this progress comes with its own set of challenges, particularly as mobile network operators (MNOs) begin the process of sunsetting and shutting down legacy 2G, 3G, and even 4G networks to re-farm spectrum assets for newer technologies. For transportations and automotive OEMs, this transition underscores the critical need for proactive planning and management to ensure uninterrupted service and maintain customer satisfaction.

The Challenge of Network Sunsets

The discontinuation of 2G and 3G networks, and eventually 4G networks, presents a significant challenge for automotive OEMs worldwide. Vehicles that rely on these networks for telematics, emergency services, and other connectivity features may find themselves unable to communicate, leading to a loss of services, functionality and a diminished user experience.


This is not just a hypothetical risk but a reality as MNOs accelerate their timeline for network shutdowns to capitalize on the efficiency and capacity benefits of 5G and beyond.

The Imperative for Proactive Network Transition Strategies

  • Conduct Comprehensive Impact Assessments

    Understand the specific dependencies your vehicles have on 2G, 3G, and 4G networks, including TCU device hardware and software support, and market variations in network sunset timelines. This will help in prioritizing updates and customer communications.

  • Develop Transition Roadmaps

    Create detailed plans for the transition of services from legacy networks to more advanced technologies. This includes hardware updates, software patches, and potential retrofitting strategies for existing vehicles on the road.

  • Foster Strong Partnerships with MNOs

    Collaborate closely with mobile network operators to gain insights into their network evolution plans. This partnership can help in negotiating extended support for legacy networks and ensuring a smooth transition to newer technologies.

  • Innovate with Future-Proof Solutions

    Invest in technology that is adaptable to future network changes. This includes hardware that supports software updates and modular designs that can accommodate new communication modules without significant reengineering.

Seize the Innovation Opportunity


While the shutdown of legacy networks poses challenges, it also offers a unique opportunity for automotive OEMs to innovate and enhance the connectivity features of their vehicles. The transition to 5G and beyond opens new avenues for services such as enhanced vehicle-to-everything (cV2X) communication, real-time data analytics, and advanced autonomous driving capabilities.
