Our writing lives with the brands that do the work.
From our content engine
echogeco writes the engineering courses.
System design, data structures and algorithms, and object-oriented programming, built from files and meant to be worked through in order. These cards open the course on echogeco's own site.

echogeco writes and publishes on its own site. Today that is three engineering courses, built from files and meant to be worked through in order. Every card below opens the complete course on echogeco.com.
Courses
System design interview preparation
Foundations, core building blocks and the distributed-systems concepts behind them, worked from first principles with the numbers that justify each decision.
Data structures and algorithms, by pattern
Fourteen patterns that between them solve most interview problems. Every problem is written from scratch, and every solution ran against its tests before it reached the page.
Object-oriented programming, by principle
What object orientation is for, which is managing change, taught one principle at a time in Python and Java side by side, with C++ brought in wherever the language changes the answer.
Engineering write-ups and the build-in-public story publish on echogeco.com as they ship. Nothing is listed here until it is real.
From our telecom division
telecogeco keeps its own whitepapers and long reads.
Open-source RAN, 5G core and spectrum engineering, written for engineers. These cards open the complete piece on telecogeco's own site.

telecogeco writes and publishes on its own site: whitepapers on the proofs of concept it has shipped, and long-form articles for engineers learning RAN and core. Every card below opens the complete piece on telecogeco.com.
Whitepapers
The Autonomous AI-RU
An open closed loop from a Non-RT RIC energy-saving rApp, over O1 and the WG4 M-Plane, to a ruApp that decides inside the radio. The demo, the physics twin, the rApp training and the ruApp, animated.

How a TR 38.901 propagation model becomes a service that predicts coverage across a cluster of cells, calibrates to measurement data, and tells you what changes when you tilt an antenna or put a cell to sleep.

Spectrum control, hop by hop
How a CBRS grant is issued by a SAS, carried by a Domain Proxy, turned into carrier configuration in the CU/DU, and written into an O-RAN radio over M-Plane. A runnable lifecycle lab: register, get granted, get authorized, and watch what an incumbent detection or a grant termination actually does to the radio.

A working course for engineers who test RAN and core. Levels, types, techniques and tools, all mapped onto one system: a UE talking through an O-RU, O-DU and O-CU into a 5G core.
Read on telecogecoFrom the core to the antenna: a radio-side primer
You know AMF, SMF and UPF. This walks the other way, from a phone's first transmission through the radio unit and the gNB, and explains split 7.2 versus split 8, the four fronthaul planes, and what a radio driver actually does.
