What is NB-IoT?

NB-IoT, or Narrowband Internet of Things, is a rising technology in the IoT space. Built on licensed cellular networks, NB-IoT offers low power consumption, strong penetration, and wide coverage. It can be deployed directly over GSM, UMTS, or LTE networks to reduce costs and ensure seamless upgrades. It supports three deployment modes—in-band, guard band, and standalone carrier—allowing it to coexist with existing networks.

Why Choose NB-IoT + 2G?

With the rapid growth of LPWA (Low Power Wide Area) networks, the NB-IoT 2G dual-mode tracker stands out as a next-generation solution for massive IoT connections. JimiIoT’s new tracker leverages the advantages of both NB-IoT and 2G to provide reliable connectivity in urban and remote areas.

1. Seamless Connectivity, Enhanced User Experience

Conventional IoT networks struggle to cover areas like underground garages or tunnels. NB-IoT alone is not yet fully deployed in all regions. To address this, JimiIoT adopts a dual-mode approach (NB-IoT + 2G). This ensures uninterrupted service and a smooth user experience even in poor signal environments, enabling fast deployment and operation across regions with varying infrastructure.

2. Massive Connection Support

A single NB-IoT channel (200kHz) can support up to 100,000 simultaneous connections per sector. With an estimated 5 million base station sites globally, and assuming three sectors per site, the technology can potentially accommodate up to 450 billion IoT terminals. This makes it ideal for national-scale or enterprise-wide deployments.

3. Low Power, Long Standby, and Cost-Effective

The NB-IoT + 2G terminal module designed by JimiIoT offers ultra-low power consumption. With optimized efficiency, it achieves up to 10 years of standby time. The low-cost module is suitable for large-scale deployment without compromising performance or reliability.

JimiIoT’s Industry-Leading Innovation

JimiIoT has consistently pushed boundaries in IoT technology. At MWC 2015, NB-IoT application demos such as smart metering began showcasing the power of this emerging tech. Fast-forward to MWCS 2018, JimiIoT presented the ET25N tracker in partnership with China Mobile. This anti-theft terminal for electric vehicles supported both NB-IoT and GPRS and was designed to eliminate signal blind spots.

Through the mobile app, vehicle owners could:

• View real-time location
• Receive instant alerts for anomalies
• Remotely disable the vehicle to prevent theft

MWC 2019: A Dual-Mode Leap Forward

At MWC 2019, JimiIoT partnered with MTK to launch the first NB-IoT + 2G dual-mode tracker, optimized for electric motorcycles and EV fleets. This compact device is:

• Small and easy to install
• Built on NB-IoT for deep coverage (garages, basements, etc.)
• Backed by 2G for fallback communication
• Designed to deliver stable performance in any environment

Applications and Future Outlook

NB-IoT is expanding rapidly across various industries:

• Internet of Vehicles (IoV)
• Smart healthcare systems
• Smart home and appliances

The complexity of IoT environments demands technology that balances coverage, stability, and cost. While 2G is still widespread, NB-IoT is becoming the future standard. The dual-mode strategy ensures a reliable transition.

JimiIoT’s launch of the first NB-IoT + 2G dual-mode positioning terminal in China paves the way for smarter, more connected solutions that meet the evolving needs of global users.

Final Thoughts

With this advancement, JimiIoT is not just meeting today’s connectivity challenges—but also shaping the future of IoT. Whether it’s for fleet tracking, electric vehicle anti-theft, or asset management, the NB-IoT 2G dual-mode tracker offers flexibility, coverage, and performance.

As JimiIoT continues to drive innovation, customers worldwide can expect smarter, more efficient, and future-proof IoT tracking solutions.
