Quectel BG770 – NB-IoT, LTE-M, GNSS module

Quectel BG770

Quectel BG770 – NB-IoT, LTE-M, GNSS module The Quectel BG770 is based on the Altair Semiconductor ALT1250. 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 […]

NB-IoT / LTEM /  LoRaWAN design question – CoAP, MQTT, MQTT-SN?


I get questions about LPWAN designs each week. The question below I will answer online, because it is a generic question. NB-IoT / LTEM /  LoRaWAN design question: Hi Harald, We’ve been in contact a few times a few years ago now (!), discussing low power wireless and RF topics. Great to see how much […]

NB-IoT for smart bin / intellegent container

akorIoT SensPRO - NB-IoT , LTE-M, GPRS reference design

Enquiry for a smart waste container We have already developed many antennas for metal containers on GSM, UMTS, NB-IoT, LTE-M, LoRaWAN and Sigfox. For us the radio technology does not make a big difference. The akorIoT SensPRO is already a reference design for such a smart bin. Request for the smart waste bin Hi Harald, […]

IoT M2M Cookbook – The outlook for embedded antenna design

GSM PCB antenna simulation

The IoT M2M Cookbook contains a simulation of a dual F antenna for cellular. This antenna has been customized several times by customers, or by us on behalf of customers. The Gillette order button using this base design and described in the book supports NB-IoT, LTE-M and GSM from about 750 MHz with 960 MHz […]

From concept to your wireless IoT button

The akorIoT Group has a development team with many years of experience in wireless data transmission which today is termed “Wireless IoT”.  The integration of antennas into enclosures is another area of expertise for the akorIoT Group; in addition to standard antennas such as solderable chip antennas or flex PCB antennas, customer-specific antennas are often […]

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 […]
