The Gemini protocol replaces the ad-heavy, JavaScript-driven web with a minimal, privacy-focused alternative built around static content and mandatory TLS. Learn Gemini’s architecture and deploy a Gemini server on Ubuntu with AWS, GMID, TLS, and systemd.
Transform Radio Reference CSV frequency data into a format compatible with the Uniden Bearcat BC125AT scanner. Explore schema mapping, analog filtering, CTCSS/DCS conversion, frequency normalization, and importing channels into Bearcat programming files.
This month's blog post continues to discuss the evolution from hierarchical to Flat Internet Ptotocol (IP) Architectures for mobile networks. Be sure to read Part One if you have not already. This post briefly discusses the components of mobile...
I wrote this white paper a while back. This paper discusses the evolution from hierarchical to Flat IP Architectures for mobile networks. This information may be of interest to mobile network architects, especially in light of the emergence of...
Over the air communications, such as text messages, satellite radio, walkie talkies and WiFi need to deal with the unpredictable effects of noise in the channel. Coding theory attempts to make noisy channels more reliable by bringing the noise...
Engineers face the reality of imperfect and noisy channels when designing digital communication systems (DCS). The engineers must account for signal degradation to ensure that a receiver receives the message that the transmitter intended....
Satellite system engineers consider the narrow beams (which lend themselves to frequency reuse) and high data rates of Ka band channels attractive for communication systems [Khan 2]. As a result, the satellite community witnessed a great increase...
This blog post summarizes the first three chapters of Bernard Sklar's Digital Communication - Fundamentals and Applications textbook. Signals A Digital Communication System (DCS) transmitter (XMT) sends a waveform selected from a finite set of...
Freshlex LLC (should) architect the reliable multicast infrastructure for the putative John Carmack biopic, which will hit the Internet in December of 2018. The first blog post discusses two of the enabling technologies, FCAST and ALC. The second...

Reliable multicast?!? How on earth can you guarantee transport using a unidirectional, asynchronous delivery method? Could you scale your solution to support ten million downstream users, each with a different capacity, varying from dial up to...
