NarrowBand-Internet of Things (NB-IoT) is a cellular wireless technology, which is based on standards with low power consumption (LPWA). It was developed to be used in a wide range of new IoT devices and services.

NB-IoT significantly improves the power consumption of user devices, increases the network capacity and spectrum efficiency, especially in deep coverage. Battery life can, in the individual cases, exceed more than 10 years when using the NB IoT technology.


The Quectel BC660K-GL is a high-performance LTE Cat NB2 module which supports multiple frequency bands of B1-B5/B8/B12-B14/B17-B20/B25/B28/B66/B70/B85 with extremely low power consumption. Thanks to its ultra-compact profile it is a perfect choice for size-sensitive applications. 

Regarding the shape and size, it is compatible with Quectel's GSM/GPRS M66 and NB-IoT BC66 module. It provides a flexible and scalable platform for migrating from GSM/GPRS to NB-IoT networks.

This multi-band module is designed for mounting using the surface-mount technology, which makes it an ideal solution for applications requiring durable and rugged designs. The module’s small LCC package allows it to be easily embedded into space-constrained applications. This type of package also suits large-scale manufacturing, as it can be fitted using automated systems.

Thanks to its ultra-compact profile, super-low power consumption and extended temperature range, the BC660K-GL is an excellent choice for a variety of IoT applications, such as smart metering, bike sharing, smart parking, smart city, security and asset tracking, home appliances, agricultural and environmental monitoring. It can also provide services for SMS and data transmission to meet various user demands.
