DFRobot's Description of the SIM7000E Arduino NB-IoT/LTE/GPRS/GPS Expansion Shield
NB-IoT (Narrow Band-Internet of Things) technology is a new IoT technical branch and supports cellular data network connection of low power consumption device in WAN (Wide Area Network), which also called as LPWAN. NB-IoT operates in authorized frequency spectrum. It can be directly deployed to GSM, UMTS, LTE without any interference of current networks, while the bandwidth consumption is just about 180KHz.
This SIM7000E Arduino NB-IoT/LTE/GPRS expansion shield is a wireless communication module produced by DFRobot and the design is based on SIMCom SIM7000E. This wireless communication module is designed for Arduino controllers, supporting multi-frequency LTE-FDD communication, dual-frequency GPRS/EDGE communication, NB-IoT communication. No matter prototype developments or small-batch productions, SIM7000C Arduino NB-IoT/LTE/GPRS expansion shield is the best solution to applications of low power consumption, low latency and meddle-throughput. Besides onboard GNSS (Global Navigation Satellite System), SIM7000E supports American GPS, Russian GLONASS, European Galileo, Japanese QZSS and Chinese BeiDou Navigation Satellite System. It can be widely applied to IoT applications such as long-distance control, moving tracking, long distance data uploading and shared bikes.
This SIM7000E been certified for use on the Telstra Mobile Network since 2015. The devices has been certified to Telstra’s guidelines and mandatory criteria. These guidelines ensure that RCM and ACMA regulatory requirements are met and devices are successfully tested through the Telstra M2M Device Certification Program. Telstra intends that its 3G service will remain until at least 2020. Full or partial geographic closure may occur any time after 2020, but would be unlikely before 2022. Full closure is most certainly expected well before 2030. So somewhere between 2020 and 2030 the 3G service will be shut down but precisely when has not yet been decided. This is why we have stopped selling the sim800 and sim900 modules. And recommend only using the sim7000e as a replacement
SIM7000 Arduino NB-IoT/LTE/GPRS/GPS Expansion Shield
The SIM7000E Arduino NB-IoT/LTE/GPRS expansion shield supports both SIM card and NB-IoT card synchronously. You can plug in a common SIM card to achieve traditional GSM applications, such as make a phone call and send message. You can also plug in a NB-IoT card to realize NB-IoT data transmission. Besides, this expansion shield provides a BME280 environmental sensor. So it could be a prototype to develop NB-IoT projects, monitoring temperature, humidity and pressure.
On May 9, SIMCom’s SIM7000E successfully passed the IMDA certification. It is the world’s first certified multi-mode module/Qualcomm platform module. On May 28, SIM7000E was certified by Telstra.
SIM7000E, the multi-mode module targeting Europe, Africa, Australia, Southeast Asia and other regions.. It supports LTE-FDD B3/B8/B20/B28 and GPRS/EDGE 900/1800MHz frequency bands. The LTE CAT-M1(eMTC) uplink and downlink transmission rates are 375kbps and 300kbps respectively, while NB-IoT’s uplink and downlink transmission rates are 66kbps and 34kbps respectively.
