Wow, 3.2 dBi  gain and 79 % antenna efficiency – a mega-great antenna, or is it?

Wifi BLE Bluetooth PCB antenna with cable

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 NB-IoT instead or LoRaWAN and 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 […]

IoT M2M Cookbook – The outlook for embedded antenna design

GSM PCB antenna simulation

The IoT M2M Cookbook contains a simulation of a dual F antenna for cellular. This antenna has been customized several times by customers, or by us on behalf of customers. The Gillette order button using this base design and described in the book supports NB-IoT, LTE-M and GSM from about 750 MHz with 960 MHz […]
