Snowden isn't explaining anything here, he's just posting a link on Twitter. HN guidelines ask you to "please submit the original source".

The original source is:

Dirtbox - Devices on Planes Used by Government to Target Cellphones (2014)

The article is definitely more detailed. But, I didn't see that picture in the article, and found the illustration quite expressive.

It's OK to add the additional link as a comment after you post the article.
