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 […]

What is NB-IoT? Lesson 1

History of name for LTE-Cat-NB1 and LTE-Cat-M1

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 a part of the 3GPP Release 13 fixed in […]
