I can carry my light antenna radiation pattern test system by car, train or aeroplane. The test reports have the same accuracy like with an electronic chamber. The main difference is price and size. The mobile antenna radiation pattern system is much smaller and cost Euro 14,000 only. To install a chamber will charge much […]
“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. […]
Last week was Meet-Up related to NB-IoT in Munich. Some Newbies were listening to NB-IoT details the first time. What they don’t know but I know – NB-IoT is already live in the region of Munich. The akorIoT community made a scan in Rosenheim close to Munich and found an NB-IoT bearer in the guarded […]
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 […]
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 the key difference between the LPWAN technologies? Just watch the 25 minutes video to learn your lesson. If you are interested in your own Weightless P BTS and some Weightless P modules then do not hesitate to drop an email to harald.naumann (at) gsm-modem.de . I will take care that you get your […]
At the end of this week Germany, like a lot of other places in the western world, will slow down. It is Christmas time and we start to celebrate on the 24th of December. Before I start to enjoy this time with family and friends I would like to say thank you for all the […]
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 […]
