The Network Sunset of 2G and 3G: What It Means for IoT and Connectivity

Network sunset overview

Network sunset refers to the gradual phase-out of older network technologies, such as 2G and 3G, as newer, more advanced networks like 4G and 5G take over. In the context of IoT (Internet of Things), network sunset impacts connected devices that rely on older cellular networks for communication.

What network sunset means for IoT

As cellular carriers phase out older networks, businesses and IoT ecosystems must adapt to ensure continued connectivity for their devices. This shift is not just about faster speeds; it’s about unlocking new possibilities for industries relying on mobile connectivity for everything from smart cities to remote device management. Transitioning to newer technologies like 4G and 5G will not only ensure the continuity of existing services but also open the door to more advanced capabilities and greater efficiency in IoT and mobile communication.

Impact on IoT devices

Many IoT devices relying on 2G/3G will become obsolete or lose functionality once these networks are deactivated. This includes applications in sectors like agriculture, healthcare, and fleet management

Why the shift?

• Faster Speeds: 4G and 5G offer higher data transfer speeds, lower latency, and increased reliability.

• More Capacity: 4G/5G networks can handle more devices and traffic, supporting the growing IoT ecosystem.

Timing and phase out

• 2G: Being phased out globally from 2025, with some regions retiring it sooner.

• 3G: Most carriers plan to shut down 3G networks by the end of 2025.

What should businesses do?

• Upgrade IoT devices: Companies using 2G or 3G-dependent devices should migrate to 4G or 5G-compatible solutions.

• Plan for the transition: Ensure device compatibility, network readiness, and consider potential downtime for existing systems.

Key strategies for IoT success amid network sunset

As 2G and 3G networks are phased out, businesses must adapt their IoT strategies to ensure continued connectivity. Transitioning to 4G and 5G technologies, ensuring device compatibility, and leveraging multi-network support are key steps for future-proofing IoT ecosystems and maintaining seamless operations.

  1. Transition to 4G and 5G
    IoT networks are evolving to 4G and 5G technologies, offering enhanced speeds, lower latency, and increased device capacity. These next-gen networks support the growing number of connected devices and meet the needs of modern applications.

  2. Device Compatibility and Connectivity
    Solutions are being provided to ensure IoT devices are compatible with newer 4G and 5G networks. This enables a seamless migration from 2G/3G to more advanced technologies, ensuring uninterrupted service for both businesses and consumers.

  3. Future-proofing with multi-network support
    With multi-network support, businesses can future-proof their IoT ecosystems, facilitating smooth transitions between network generations. This approach keeps devices connected, even as older networks are phased out.

  4. Software and firmware updates
    Legacy devices that rely on 2G/3G networks can be updated with new firmware and software to support 4G/5G, extending their lifespan and avoiding costly replacements.

  5. Global connectivity management
    Global connectivity management solutions enable businesses to oversee and manage IoT connectivity across regions with varying sunset schedules, ensuring continued operation of IoT solutions worldwide as networks retire in different locations.

The impending network sunset of 2G and 3G networks presents a critical opportunity for businesses to transition to more advanced technologies like 4G and 5G. By upgrading IoT devices, ensuring compatibility, and adopting multi-network solutions, companies can safeguard connectivity, enhance performance, and future-proof their operations. Proper planning and timely action are key to ensuring a smooth transition, avoiding disruptions, and maintaining seamless IoT service across global markets. Embracing the shift to next-gen networks will unlock the full potential of IoT in an increasingly connected world.
