Description:
The NB-IoT and eMTC (enhanced Machine Type Communication) are rising IoT communication technologies that evolved from LTE (4G), with advantages including 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. At the same time, 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.
