Superficial knowledge in NB-IoT

NB-IoT knowledge

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 […]

NB-IoT versus SIGFOX, LoRaWAN, and Weightless – power / energy the inconvenient truth

NB-IoT power consumption

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 […]

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 […]

LPWAN coverage range on radio propagation – NB-IoT, Weightless, LoRaWAN & SIGFOX

If you are planning to deploy your own LPWA network then you’ll need to understand a few things about RF signal propagation, run a few models and then conduct a few tests in the real world. In this article, we are going to explore what is involved so fasten your seat belts and let’s go… […]

NB-IoT Hackathon – 23th of June – Berlin, Germany

UDP/Ip on NB-IoT send by akorIoT radio adapter

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 […]

akorIoT – world´s first Arduino shield with support of LTE Cat-M1 & LTE-Cat-NB1 (NB-IoT) & EGPRS

Radio adapter with Arduino header and support of NB-IoT, LTE-CAT-M1, EGPRS and GNSS

“akor” is the Proto-Celtic word for “open”. The akorIoT radio adapter with its Arduino R3 header has an open HW and SW concept and supports the multi-mode cellular module B96 as well. Based on that it is the world’s first Arduino shield with the support of both new cellular LPWAN technologies LTE-Cat-NB1 (NB-IoT) and LTE-Cat-M1. […]

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 […]

400 students have already enrolled at the IoT-University

Direction in LPWAN

The IoT-University was launched just one month ago. In just four weeks there are more than 400 students on the course. Students want to learn and to educate them we need more mentors who love to share; we have space for eight more to join us. If you have something to share, join us. Become […]
