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 […]
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 […]
Field test: tracking indoor and outdoor In order to demonstrate the tracking of goods and assets across borders, a field test was executed over several days in different countries using different methods of transport. In addition to delivery vehicles and cars, trams and walking were also used. The car was parked in an underground car […]
Everybody talks about protecting the environment and recycling. The nail antenna from the land of poets and thinkers (Germany) follows this trend. We’ve hit the nail on the head with this design. We don’t need a new nail – no we use old, superfluous, rusty nails and recycle them into valuable, perfect GNSS antennas. This […]
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, […]
How your wireless IoT idea can become a real product The Timeline: May 2018: Inquiry Tracker with harald.naumann (at) lte-modem.com February 2019: Order for development with akorIoT Group August 2019: Pre-series/ field test order with akorIoT Group Basis = akorIoT SensPRO http://www.gsm-modem.de/M2M/m2m-componets/akoriot-senspro-reference-design-nbiot-ltem/ Radio modules = Quectel BG96 Multimode NB-IoT, LTEM, GSM GNSS Module= Quectel L76L, […]
Last week I got a request to support a small GPS tracker. The request is not new to me. It reaches me in several times per year. However, it makes no sense to reinvent the wheel again and again. To minimise the effort for your GPS tracking project on NB-IoT, LoRaWAN, SIGFOX or Weightless P […]
Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway? If yes then it makes sense to follow a train of thoughts listed in my IoT M2M Cookbook. Everybody can make such a gateway real for less than USD 15. In my IoT M2M Cookbook – excerpt here: http://www.gsm-modem.de/M2M/m2m_iot_cookbook I explained […]
The idea for the NB-IoT shield with Arduino header was conceived in summer 2016. We then produced the first version of the NB-IoT shield at the M2M Summit in September 2016. The second generation was shown to readers of my IoT/M2M Cookbook in our end of the year mailing and it has proved extremely popular; we […]
We have extensively tested the HARduino board over the past few days. We have been testing the GSM version due to the lack of NB-IoT coverage in the region of our office in the North of Germany but both NB-IoT and GSM exhibit the same characteristics in the tests we carried out. The AT command set […]
