The LPWAN game changer – 1 Euro per SIM card and year

1 Euro per SIM and year

The Germans are the masters of long words and long sentences with the verb at the end (frustrating simultaneous translators the world over). German datasheets are 30% longer, or in a font size so small they are hard to read.  But, Germans are capable of short stories as well. To cut a long story short, […]

Clever SW stack on LoRa modules in Lower Saxony – Germany

LoRa PCBs

The LoRaWAN software stack is based on plain Aloha. Plain Aloha is a model that describes the typical package loss due to collisions of uplink transmissions in an unsynchronised communication system. With a LoRaWAN system, the model shows 82% package loss at maximum throughput. On top of this we get additional package loss during LoRaWAN […]

Internet of Things Case Study – Smart Parking

Internet of Things Case Study – Smart Parking – “Telemoritz” in Hanover

In Patras, Greece, developers are already working on a smart city technology development using NB-IoT. But how can they avoid the need for a SIM card and its subscription? Let’s consider the technical proposition. Technical needs Smart parking sensors are sending one status update message of 10 bytes two to eight times per hour. 30 […]

NB-IoT live in major German cities

NB-IoT-module on Arduimo shield

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 […]

Low cost BLE-GPRS-GPS-gateway

Bluetooth-GPRS-GPS-gateway

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 […]

NB-IoT shield with Arduino header renamed to akorIoT

NB-IoT Shield Arduino

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 […]

NB-IoT and band 70 – What is your opinion?

Radio wave lambda

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 […]
