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 […]
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 […]
The physics in US is the same than in Europe. The energy consumption of a radio transmitter is computed by multiplying the power output with time. LPWAN in the unlicend band in the US has not to follow a duty cycle but a maximum time of 400 ms per data package plus frequency happing. The […]
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 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, […]
The LPWAN world is about to be turned upside down, and this is your chance to be part of it. SIM cards for 1 Euro 10 Euro, running time 10 years, 500 MB => 50 MB per year, 1 Euro per year, about 8 cents a month! Additional data volume bookings possible 500 MB upload […]
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, […]
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. […]
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 […]
Please note that I will add further modules later and that, on request, different parameters can be used in the calculation. The data in the graphic is real and was generated for a report published by a German university for a large metering customer. The report was presented during an NB-IoT seminar September 2017 with […]
