I have spent last months with preparing the launch of so called 5G stand-alone (SA) in my job at Ericsson together with the operator “3”, TV4 Sweden, TV2 Denmark and Sony. With two events, one in Sweden (1st June) and…
I don’t want to use any fancy materials, regular old FR-4 should work fine here. That means that the RF performance is somewhat non-ideal due to the dielectric, and some due to the quality of the weave. I have chosen…
A shallow dive into the different methods that can be used for electromagnetic (EM) simulation, with focus on RF circuit board simulation. Background RF design is a tricky beast to tame, and from my experience working with people in the…
Last time I wrote about my CNC laser, the end result was a rats nest of wires, and I’d only tested it briefly. Since then, a lot has happened in other parts of my life, and I found myself with…
I saw a video on youtube a while back, and inspiration struck: “I could make a smaller version of that!”. At the time, I was working as a radio firmware engineer on one of the largest semiconductor companies in the…
I’ve found myself many-a-times wanting a laser, especially for conducting experiments related to printing PCB’s. However, this is not a deep-dive into locally depositing copper onto a substrate from saturated copper sulfate solution using a laser, this is about building…
After reading this article you should feel that you know the very basics of radio systems. What are the main functions, components, what are the main challenges and where does it fit in the bigger Radio Access Network (RAN). RAN…
The next generation of wireless communication is about to become reality. Mobile operators are investigating new infrastructure and phone manufacturers will start to roll out 5G-ready phones already this year. This generation has been in development for many years but…
