Actually too broad covers it quite well and clearly. Therefore I can't tell whether your problem is not understanding what "too broad" means, or not understanding why the question was too broad.
"Too broad" means that too much information or background material would have to be given to answer the question. This is a poor match for our Q+A format, so we don't allow it. Since it comes up often enough, we even have a specific canned close reason for it. That way the people voting to close don't have to write the same explanation each time. They just click "too broad" and move on to more useful things on this site.
Your question makes a great poster case for "too broad". It's basically asking us to compare and contrast all the wireless communication technologies. Really!? First there are so many of them, then there are so many parameters that could be relevant to picking one in any particular case. The answer would need a book or several books.
If you didn't mean to ask the question such that the answer is a book, then you have to go back and ask specific things about specific aspects of specific wireless technologies. However, you didn't, so the question is clearly way too broad, and was correctly closed as such.
