NB-IoT Module
TPB41 - NB-IoT Module/Multi Band
TPB41 is a Narrow Band Internet of Things (NB-IoT) universal wireless communication module. The TPB41 is based on 3GPP release 13 protocol, is compatible with Release 14, and supports multiple bands. It is widely applied to smart city, smart transportation, wearables, and environmental monitoring. 
This module is compatible with traditional GSM/GPRS modules based on design and makes it easy for customers to upgrade their technology. It is compliant with CCSA standard 16x18mm size and pin definition, making it more competitive in size. 
Sercomm also provides an NB-IoT EVK board, which is easy for customers to develop and debug.
