Dear Osmocom community,
I'd like to share this with you, as I believe not many have read the book "GSM and UMTS; The Creation of Global Mobile Communications" by Friedhelm Hillebrand (who by the way just received the Order of Merit of the Federal Republic of Germany for his substantial contributions to mobile communications).
The document (and some others on the included CD-ROM that comes with the book) reminds me to the much more widely known "Aprils Fool RFCs" within the IETF. It's a pity that ETSI - unlike IETF - didn't go through with it and hence those documents were never officially published, so that today only some fax scans seem to exist.
Enjoy!
