nordin bouchtaoui at gmail.comIf you have a nanoBTS, you can install/setup and run your own network very easy. There is no E1 interface needed or a special lib or a modified kernel or something. Just install debian and other libs you can easily install it with apt, git-clone the project and connect the bts with a utp-cable and you're on the go. If I can do it, I'm sure everybody else can do it. When you get that running, than you can talk about lack of documentation, or better design or whatever. Good luck.
