    NB-IoT is a new wireless technology in LPWAN (Low Power Wide Area Network). Different from LoRa or Sigfox, NB-IoT comes from Telco instrastructures, in Malaysia, it must be coming from Maxis, Celcom, Digi, TM, etc.

    This is NB-IoT HAT for Raspberry Pi, comes with SIM7000E module that mainly applicable in Europe, Africa, Australia, Southeast Asia that support Band 3, 8, 20 and 28.

    Note: This HAT can only be used with NB-IoT SIM card, and only support B3, B8, B20 and B28, and of course coverange will depends on respective Telco NB-IoT network. Cytron is not responsible for SIM card, wrong network band and network coverange.

    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.
