Helium Hotspot Performance Analysis With Hotspots Health

The idea behind the Helium project really struck me as a unique intersection of radios, decentralization, and cryptocurrency. And as The Peoples Network keeps growing I saw a need to somehow quantify how well your hotspot is doing at its current position compared to the other hotspots around you. This is because the amount of… Continue reading Helium Hotspot Performance Analysis With Hotspots Health

Radio Resilience Competition at GRCon21

As part of the GNURadio Conference 2021, the Radio Resilience Competition created a custom competition just for the conference. This is similar to the Capture the Flag (CTF) that has been a mainstay of the GRCon. The cool thing about this competition is that it was not just for bragging rites but real prizes! The… Continue reading Radio Resilience Competition at GRCon21

The Amazing NanoVNA V2

A Vector Network Analyzer (VNA) is an important test and measurement tool for RF electronics. It is capable of measuring both transmission and reflection of an electronic network. An electronic network is just a connection of electrical components, such as resistors, inductors, and capacitors, etc. This is not to be confused with an IP network… Continue reading The Amazing NanoVNA V2

Simulating Helium with HotspotRF

With any successful wireless system, you want to have some theoretical basis that your transmitted information can reach its intended receiver with enough power to be deciphered correctly. This is the basic idea behind a link budget where you compile information about your radio hardware and setup such as transmitter power, receiver sensitivity, antenna gain,… Continue reading Simulating Helium with HotspotRF

2.4GHz PCB Patch Antenna V2 Design with Matlab

I previously create a PCB patch antenna using the Matlab antenna design toolbox and had some pretty good results, but the narrow bandwidth of patch designs means that small errors in the simulation parameters cause a shift away from your desired frequency. My old post into the details of my journey of learning about patch… Continue reading 2.4GHz PCB Patch Antenna V2 Design with Matlab
