ARC1 with the latest NB-IoT and LTE-M mobile communications technology



INSTROTECH – proud representative of Keller in SA – has announced the upgraded of ARC1, the IoT communications module, to the latest transmission technology with NB-IoT (narrow band) and LTE-M. Keller was able to adapt the firmware and integrate the hardware (new transmission module) in no time at all, thanks to a modular design.


Earlier in 2019, mobile communications providers announced that the new NB-IoT and LTE-M standard would be rolled out in late 2019, and be available for energy-saving IoT devices. Based on the fourth generation of mobile communications technology (4G), this technology uses the LTE transmission technology and serves as an interesting alternative to other data transmission technology, such as LoRaWAN, for example.

NB-IoT and LTE-M features:
•    Low power consumption, (longer lasting battery)
•    Higher transmission ranges or lower penetrations through the building
•    Lower hardware costs
•    Enough data throughput for IoT applications or for sending measurement data
•    Can be used around the world with roaming and specific frequencies

The ARC1 IoT device is used everywhere where pressure is measured or water levels need to be recorded. The ongoing digitalisation of cities (digital city) and Industry 4.0 have brought about demand for IoT (Internet of Things) devices.

Thanks to the modular design of the ARC1 remote transmission unit, Keller was able to integrate this technology into the KELLER AG für Druckmesstechnik ARC1 after a short development phase.

The first series of the ARC1 devices with NB-IoT and LTE-M transmission are currently being field tested. Test devices can already be delivered to users on request.

The data sent by ARC1 can be accessed at any time, from anywhere in the world, directly in the KOLIBRI Cloud ( Contact INSTROTECH on 010 595 1831, for in latest NB-IoT and LTE-M mobile communications technology from Keller.
