Request for NB-IoT antenna design

From www.gsm-modem.de 20 hours ago in Blogs

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...

Request for an NB-IoT PCB antenna

From www.gsm-modem.de 2 days ago in Blogs

Another request for a custom PCB antenna for NB-IoT. Since we invested in NB-IoT early on, we can bring in a lot of experience. Simply taking over a layout of an antenna for an unlicensed band like LoRaWAN (868 /...

Wow, 3.2 dBi gain and 79 % antenna efficiency – a mega great antenna

From www.gsm-modem.de 7 days ago in Blogs

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...

Why to use NB-IoT instead of LoRaWAN or Sigfox?

From www.gsm-modem.de 1 week ago in Blogs

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...
