NB-IoT - eMTC - EDGE - GPRS - GNSS HAT for Raspberry Pi

The NB-IoT - eMTC - EDGE - GPRS - GNSS HAT for Raspberry Pi has 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.

Description

The NB-IoT - eMTC - EDGE - GPRS - GNSS HAT for Raspberry Pi has 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.

Guter 2/3/4G HAT mit leichten Designschwächen
4 from 5

In Kombination mit einem Raspberry Pi Zero W und einer Micro Sim funktioniert dieser HAT ausgezeichnet im österreichischen Mobilfunknetz. Dank einer eigenen USB Buchse können Testkommandos und Firmwareupdates auch über den PC gesendet werden. Der Transceiver Hersteller SIMCom stellt umfangreiche Dokumentation und Tools zu Verfügung.

Die unterstützten LTE Bänder sind in Europa gerade noch ausreichend. Leider werden Band 1 und 7 nicht unterstützt was in Zukunft in Städten vielleicht Probleme mit sich bringt.

Zwei Punkte sind mir aufgefallen:
- Für ein erfolgreiches Firmwareupdate über die USB Buchse mußte ich den HAT vom Raspberry Pi Zero abziehen
- Die Klapphalterung für die SIM Karte ist mittig unter dem Modul angebracht und nur erreichbar wenn der Raspberry Pi Zero abgezogen wird.

Die Plazierung des SIM Karten Halterung ist meiner Meinung nach ein Designfehler da die Karte im eingebauten Zustand nicht getauscht werden kann. Dafür habe ich bei der Bewertung einen Punkt abgezogen.
