Basically you are in a large metal cage, screened on all sides by metal sheeting through which the tiny receiver / transmitter in your phone can't penetrate = No signal.

it goes like this, the signal received by our mobile phones are electromagnetic in nature . these waves CAN PENETRATE through any DIELECTRICmedium easily , there is no loss of the signal in the case of dielectric medium . if the medium is a combination of both dielectric and a conducting medium,there occurs some LOSS of signal,such a medium is called a LOSSY MEDIUM.and if the medium is a conducting medium then these signals CANNOT PASS through such medium. in the case of an elevator it is a total conducting medium , thus u donot receive any signal in u'r phone....... i hope this helps u............

An elevator is a grounded metal box, technical name "Faraday Cage". A Faraday Cage will attenuate/annihilate any radio signals trying to enter or leave it. Hence your phone doesn't work because it's a radio too.

because the signal is mainly line of sight
meaning if the mobile phones
antenna is not in sight of the mast's
signal,then it will not recieve anything,basically!

I'd love to think it was specially designed that way so you couldn't annoy the hell out of other people by using it in such a small confined space, but I think the posters above may be correct...

basically you are surrounded by metal, and then also surrounded by reinforced concrete, plus there are all those metal cables interferring, same thing can occur in cellars etc.
