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 […]
NB-IoT networks worldwide In nominal data, 15 economies would have GDP above $1 trillion, 62 have above $100 billion and 177 have above $1 billion. Top five economies account for approximately 53.82 %, whereas top ten accounts for approx. 67.19 %. top 20 economies add up to over 80%. 92 smallest economies only contribute 1 […]
Deutsche Telekom AG has its NB-IoT network live in several major German cities (Berlin, Bochum, Bonn, Chemnitz, Dortmund, Duisburg, Düsseldorf, Erfurt, Essen, Gelsenkirchen, Cologne, Leipzig, Leverkusen and Mannheim. There are now no longer any obstacles to developing and using NB-IoT applications. akorIoT with NB-IoT + one of 33 STM32 Nucleo or Arduino UNO = your […]
Rank 1 to 3 I have rated by the number of LPWAN base stations. If I rate by the density of the base stations per square meter then the Netherlands is in the first place. We could also rate by the number of base stations per inhabitant. I decided to rate the base stations per […]
A dream came true. Within the last days, NB-IoT is moving in big steps. Orders for a new combined module on NB-IoT (LTE-Catt-NB1), LTE-Cat-M1, GPRS and GNSS (GPS, GLONASS) are welcome. If you miss NB-IoT or Cat-M1 for now, then just use the GPRS radio inside the module. Requests for data sheets, orders for samples […]
Last week was Meet-Up related to NB-IoT in Munich. Some Newbies were listening to NB-IoT details the first time. What they don’t know but I know – NB-IoT is already live in the region of Munich. The akorIoT community made a scan in Rosenheim close to Munich and found an NB-IoT bearer in the guarded […]
Today the bunny will jump out of the heat. Next week at the embedded world you have a chance to win a Gold, Silver, Bronze and Student kit. The Student kit has a higher value than the Bronze kit. Students are our future. All kits together have a value of mare than Euro 10000. The […]
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 […]
Many IoT / M2M Cookbook customers asked me for an evaluation kit within the last two years. I launched the first version during M2M Summit in September 2016. In February 2017 the multicellular version came true. The working name is HARduino because it has an Arduino R3 compatible UART interface. HARALD – ALD + duino […]
RF engineers already know that signal propagation characteristics vary according to frequency. In simple terms, signals carried at lower frequencies travel further. Since wavelength equals the speed of light divided by the period of the carrier signal, we can see that low frequency signals have a long wavelength. Long wavelength, low frequency radio waves are […]
