My name is Mychaela Falconia, I am a Goddess priestess with a strong interest in retro cellular technologies (I strongly disagree with and disapprove of the direction in which the mainstream telecom industry chose to evolve in later technology generations), and I use Themyscira Wireless brand (or ThemWi for short) for all of my work with GSM cellular technology, also known as 2G.
My main work these days is building a new GSM/2G network in a few small select locations in USA, specifically those rural and remote locations with available spectrum vacancies in either PCS1900 or GSM850 band. This work is being done through American 2G Cooperative — see www.usa2g.org.
The new network of A2GC is being built with Osmocom Cellular Network Infrastructure software suite driving legacy BTS hardware from Nokia and Ericsson. (The BTS is legacy hw, then Osmocom stack is used from the BSC up.)
To make this approach work, we need to make a lot of improvements and extensions to this FOSS GSM network software. Much of this work takes the form of patches to Osmocom CNI components themselves, most of which have already been accepted and merged into Osmocom mainline. However, some extended functions are implemented in the form of entirely new add-on software components that work together with standard Osmocom CNI; these add-on components are maintained in ThemWi area of Osmocom Gitea. Finally, speech codec libraries and related experiments are maintained in our own Mercurial repositories.
Prior to taking on the network side of GSM, my personal goal was to design and build my own GSM phone handset, for highly personal reasons which can never be justified to anyone other than me. This project is named FreeCalypso and has its own website. (FreeCalypso project dates back to 2013 and is thus an older brand of mine than Themyscira Wireless.)
GSM has the network side, which we handle with Osmocom CNI software stack and solidly built macrocell BTS hardware from the olden days, and it has the mobile side, where we have our own FreeCalypso GSM MS. And then there is the third realm: SIM cards. They are supposed to be issued by network operators, but physically exist on the mobile side. This page describes our programmable SIM card model and the tools we developed for it.
If you would like to converse with me (Mother Mychaela) regarding any of my GSM work, please feel free to email me. Please also see this page regarding our mailing list revival plans.
