Because a picture is worth a thousand words, as promised here is the NB-IoT throughput table in a graph. At a 144 dB link budget, we will reach 21 kbps. If the link budget is even higher, the transmission power will be reduced. The 3 coloured curves show the 3 operating modes of NB-IoT. The […]
NB-IoT has a very high throughput at the top end. At the lower end it is faster than other LPWA techniques. For LoRaWAN, Weightless and NB-IoT the distance and the data throughput also regulate the speed. In this lecture we will only consider NB-IoT due to the limited talk time. At first glance, the table […]
In 60 minutes, we’ll explain antenna design basics. Questions during the presentation are welcome as well as at the end of the presentation when I have allowed time for questions and answers.
As many people have asked for a video stream of my presentation, I am now publishing the presentation with text. This will take a while to complete, but I have made a start with slides 7 to 9 published in my blog. Self Made Embedded Antenna Designs versus Chip Antenna My name is Harald Naumann […]
Slide 7, 8 and 9 from our lecture “Self Made Embedded Antenna Design versus Chip Antenna” The following applications are representative of those adopted by many of our satisfied customers. We are not yet authorized to show some of them, but we will reveal more details in due course, and many applications will become public […]
On Dec. 12, the world’s first NB-IoT Christmas party with integrated NB-IoT seminar will take place in Tilburg in the Netherlands. Agenda (PDF): IoT2Learn-agenda-hotel-arrival IoT2Learn at a glance NB-IoT SIM cards to test for the guests on the day before the seminar www.iot2learn.com Surveying of your antennas free of charge after arrangement on return loss […]
In the last quarter of this year, there will be a few more highlights. Electronica Electronica will be in Munich from November 13 to 16. Take a look at Tekmodul at booth C3.148. Once again, there will be a fireworks spectacle of radio news. I have the first German long-term tracker akorIoT SensPRO with multiband […]
There is no reference for antennas on extremely small boards in small packages. Cellular chip antennas of different manufacturers all have a reference ground plane of approx. 45 mm +/- 10 mm x 100 mm +/- 20 mm. Nobody can cheat the physics. The length of the PCB influences the return loss. This is documented […]
The oldest delivery service is certainly Santa Claus. He has been delivering punctually to children for generations. Santa Claus lives in his factory at the North Pole. Santa’s helpers are the gnomes. They make gifts for the children. At Christmas Santa Claus packs all the presents on his sled. As we now, reindeers pull the […]
The clear winners at Wireless IoT in the WAN area are the 3GPP technologies. With NB-IoT, LTE-M and the well-established cellular techniques, 3GPP covers most applications. On top of that, cellular operators have the better and denser network. There are 76000 cellular base stations in Germany. They are opposed by 0 LoRaWAN and 2500 announced […]
