Telecom Operators and who supplies their network - Under Construction

I am constructing a database (for my work, as well as for my own use) a list of operators and which vendors supply to which part of their network. This is essentially a repository (a hard disk) for me. They are all public domain knowledge, but it is hard to get all of them in one place.

If you know some information, please give me your feedback via comments, I will update this article.
