HI At least the last time I dug into it … the project is about 2% hardware and 98% software. Most of a Grandmaster is the same hardware that a slave uses.
Getting timing from various cell systems has been tried both commercially and experimentally. The issue is that you are at the mercy of the cell system operator. He may / may not care about timing. He may switch timing sources at random. The net result is a very poor source of time sync. It also results in a lot of stuff showing up surplus so it’s not all bad ….
