Products Description：

NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage. Battery life of more than 10 years can be supported for a wide range of use cases.

New physical layer signals and channels are designed to meet the demanding requirement of extended coverage – rural and deep indoors – and ultra-low device complexity. Initial cost of the NB-IoT modules is expected to be comparable to GSM/GPRS. The underlying technology is however much simpler than today’s GSM/GPRS and its cost is expected to decrease rapidly as demand increases.

NB-IoT Shield is an expansion board for Arduino to add NB-IoT technology. With NB-IoT Shield and Arduino, user can study/evaluate and do POC for NB-IoT solution rapidly.

The NB-IoT Shield is loaded with offshore NB-IoT module. include:
Nb-IoT Bee 95G, it uses Quectel BC95-G module. This module is a global regions module can work on different operators.
Nb-IoT Bee QG96, it uses Quectel BG96 module. This module supports mutli-bands. Except NB-IoT, It also support LTE Cat M1 & EGPRS.
