Quectel BG951 – NB-IoT, LTE-M, GNSS module

Quectel_BG951

Quectel BG951 – NB-IoT, LTE-M, GNSS module The Quectel BG951 is based on Altair Semiconductor. The eDRX (extended Discontinuous Reception)/PSM (Power Saving Mode) ensures low power consumption. With a super-low current consumption of approximately 1,5 uA in PSM mode, the Quectel BG951 offers a long operating life of 10 to 15 years on a single […]

The eDRX (extended Discontinuous Reception)/PSM (Power Saving Mode) ensures low power consumption. With a super-low current consumption of approximately 3 uA in PSM mode, the Quectel BG770 offers a long operating life of 10 to 15 years on […]

akorIoT SensPRO – reference design for NB-IoT and LTE-M

akorIoT-SensPRO top view

akorIoT is a portmanteau word from “akor” and “IoT“. “Akor” is the ancient Celtic word for “open”. The goal of the akorIoT SensPRO was to create an open platform similar to the idea of a Programmable Logic Controller (PLC). As with a PLC the programmability, storage of the program in memory and the execution of […]

LoRa module 2400 MHz

LoRa-2400-MHz coverage

The comparison of the range of a LoRa module with 2400 MHz, Bluetooth long range modules and LoRa 868 MHz modules shows that BLE long range is not a real long range. LoRa 2400 MHz with SF12 is not much worse than LoRa 868 MHz. LoRa 2400 MHz is not subject to any duty cycle. […]
