Telecom, explained by the people wiring it up.
Long reads for engineers who want to understand mobile networks properly: how the radio side works, how a 5G system is tested, and what we learn integrating open RAN and core stacks. Written to be read start to finish, with interactive figures where a picture teaches faster than a paragraph.

What it takes to build a 5G network
A plain-language explainer of how private and public 5G networks are built: cells, MIMO, handover, and how many radios, basebands and cores a network needs.

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 DU and CU, 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.

Testing a 5G network, end to end
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.

From 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.
