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 […]
Date: Starts June 23 2017 at 8.00am / Ends June 24 2017 at 4.30pm Venue: @ hub:raum Winterfeldtstraße 21 10781 Berlin There will be an NB-IoT Hackathon in Berlin, Germany. Developers and start-ups are being called to disrupt today’s IoT landscape by creating services & solutions based on the NB-IoT technology. NB-IoT stands out due […]
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 […]
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 […]
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 […]
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 […]
Fundamentally, there really is no such thing as “NB-IoT”. The correct term is “LTE Cat NB1”. This technology is sometimes confused with Cat-M, which is another misnomer. The correct name for “Cat M” is LTE Cat M1. Both these technologies, LTE Cat NB1 and LTE Cat M1 are just subsets of “classic LTE” and are […]
Embedded LPWAN & NB-IoT antenna consideration On first quick look the choosing of the right integrated antenna for LPWAN & NB-IoT looks easy. In comparison to the large number of LTE bands the selection is simple because LPWAN (e.g. LoRaWAN, Sigfox, Weightless N) and NB-IoT (EC-GSM and NB-IoT) are on 900 MHz. There is no […]
