What you will learn
- PCB, ground-plane, and clearance guidelines that ensure consistent efficiency across NB-IoT low/high bands and GNSS L1
- How to route the RF paths and implement the matching networks used in three validated band-group solutions for USA, global, and EMEA deployments
- Real-world efficiency and OTA (TRP/TIS) performance results demonstrating ~20 dBm radiated power and robust GNSS sensitivity in a compact reference design
This guide is for
RF engineers, hardware designers, and product teams building NB-IoT or NB-IoT + GNSS.
If you’re dealing with challenges such as limited PCB space, poor low-band efficiency, NB-IoT/GNSS coupling, or unpredictable matching behavior, this guide is for you.
