From time to time developers ask questions about the content of the IoT M2M Cookbook. This time the question involves 5G and I explain why I’m not currently writing on this subject. Question about the IoT M2M Cookbook Hello Harald, I’d like to buy the IoT Cookbook. Are new networks like NB-IOT and LTE-CAT-M covered? […]
NB-IoT for smart bin / intellegent container
Enquiry for a smart waste container We have already developed many antennas for metal containers on GSM, UMTS, NB-IoT, LTE-M, LoRaWAN and Sigfox. For us the radio technology does not make a big difference. The akorIoT SensPRO is already a reference design for such a smart bin. Request for the smart waste bin Hi Harald, […]
Which protocol should I use for my NB-IoT / LTE-M Tracker?
Which is better: UDP, TCP, MQTT, CoaP or LWM2M? Q: Our application is an asset tracker on NB-IoT, LTE-M, GPRS and GNSS. We need to send the current position of the tracking device to a remote server after a particular interval. I am looking for the LWM2M protocol which consumes less energy & headers added […]
Simulation of NB-IoT coverage in Kirchheim
The grey map with the blue triangles shows the cellular base stations in the Kirchheim area. This map is available online from the Federal Network Agency in Germany. In Germany the locations of the cellular base stations are publicly accessible for everybody. The base stations vary in height from about 5 m up to 48 […]

Request for NB-IoT antenna design
Questions and answers about NB-IoT antennas are given below. This customer bought my IoT M2M Cookbook, built several NB-IoT PCB antennas based on the template in the book and needs some support. You can easily copy the NB-IoT / GSM antenna in the book into your own PCB design. However, as soon as the PCB […]
Request for an NB-IoT PCB antenna
Wow, 3.2 dBi gain and 79 % antenna efficiency – a mega-great antenna, or is it?
Do you use antennas in your products? Do you compare data sheets? Do you have problems comparing? Are the antennas in your device not compliant with the data sheet? Are there problems with radio certification? Then I will be glad to help you, starting with the analysis of the data sheets all the way up […]
Why to use NB-IoT instead of LoRaWAN or Sigfox?
Why now NB-IoT instead of LoRaWAN or Sigfox? There are hundreds of reasons for NB-IoT and hundreds against LoRaWAN and Sigfox. Below is a typical example. The potential customer already prefers NB-IoT and we can deliver NB-IoT with fallback to GSM. In Germany there is no Sigfox Indoor in my city. In the three neighbouring […]
