Nb-Iot/Emtc/Edge/GPRS/Gnss Hat for Raspberry Pi

Applicable Region

Overview

This Raspberry Pi HAT features multi communication functionalities: NB-IoT, eMTC, EDGE, GPRS, and GNSS.

The NB-IoT (NarrowBand-Internet of Things) and eMTC (enhanced Machine Type Communication) are rising IoT communication technologies evolved from LTE (4G), with advantages include low power, low cost, wide coverage, etc. They are suited for applications such as intelligent instruments, remote controlling, asset tracking, remote monitoring, E-health, mobile POS terminals, sharing bikes, and so on. While the GSM/GPRS, and EDGE are traditional 2G/2.5G technologies capable of sending SMS or making other wireless communications.

Therefore, the SIM7000C NB-IoT HAT would be an ideal choice for either evaluating new rising technologies, or simply communicating/positioning via multiple ways.

Features
