As Freddie Mercury sang: “The show must go on”. After our Successful NB-IoT Roadshow with stops between Berline and Vienna in 2017, we return to Berlin on June 28th. “Berlin ist eine Reise wert” (“Berlin is well worth a visit”). June 28th is a Thursday. so anyone who will can take Friday as a day […]
akorIoT Nano with Arduino Nano / STM32 Nucleo 32 and NB-IoT, GSM and GNSS module
NB-IoT reference design in credit card size including PCB track antenna The wireless IoT market is crying for small mobile devices transmitting for years from tiny batteries. With akorIoT Nano we developed the next open design. “akor” is the Proto-Celtic word for “open”. With placing the order for akorIoT Nano you get the schematic diagrams, […]
Comparison of TX energy consumption across LPWAN in EU 12 bytes on NB-IoT, LoRaWAN, SIGFOX and GSM/SMS)
After comparing NB-IoT, LoRaWAN and SIGFOX’s energy consumptions during transmission in the USA and Europe, here is another direct comparison with GSM and SMS. SIGFOX and LoRaWAN repeatedly call out their low energy consumption when compared to SMS with wake-up and registration on the GSM network. Their commentary is that the two unlicensed LPWAN technologies […]
Comparison of TX energy consumption across LPWAN in US (12 bytes on NB-IoT, LoRaWAN, SIGFOX))
Comparison of TX energy consumption across LPWAN in EU (12 bytes on SIGFOX, LoRaWAN, NB-IoT)
The energy consumption of a radio transmitter is computed by multiplying the power output with time. The graph clearly shows the envelope of various LPWA transmitters in Europe over time. In Europe SIGFOX and LoRaWAN are limited to 14 dBm TX power. SIGFOX and NB-IoT are along the right scale of time axis. However, in […]
The LPWAN game changer – 1 Euro per SIM card 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, […]

How to achiev a redesign from unlicensed LPWAN to NB-IoT and back? – A basic idea
How do you achieve a redesign from BLE/WiFi to unlicensed LPWAN or NB-IoT? What are the pitfalls you might encounter during the redesign? Why can you not use any old antenna to do the job? What you have to know to pass radio certification in different regions? The unlicensed SubGHz bands in Europe, US, Australia, […]
Thrilling public US LPWAN Champion Hurdle – 2018-02-11
T-Mobile on NB-IoT was the winner in a thrilling public US LPWAN Champion Hurdle. T-Mobile entered the NB-IoT horse trained by parent company, Deutsche Telekom in Germany. The surprise second place was taken by Verizon, also ridden on an NB-IoT horse. The runners up in the first LPWAN race of 2018 were the unlicensed riders. […]
Superficial knowledge in NB-IoT
Unfortunately, it is a regular occurrence that people in marketing departments without technical expertise constantly recycle the same rumours and “news” about NB-IoT. Most of these “professionals” have never been inside a technical university and probably did not pass a basic course in physics at elementary school. These same people probably did not choose the […]
