SIM7000E NB-IOT HAT
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 SIM7000E NB-IoT HAT would be an ideal choice for either evaluating new rising
technologies, or simply communicating/positioning via multiple ways.
