There are antenna's which can be used to block the signal from cellular phone companies.
I think they send bogus information over the GSM bands (900MHz, 1800MHz, 1900MHz) which causes your mobile not to find the signal of your phone company.
This is banned in a lot of countries, because not only you will block phonecalls, SMS and 3G, you will also block emergency lines (911 in USA, 112 in Europe).

it truly is an EMI / EMC question. ideal separation and protective of the channel tunnel is a could, as consistent with international Certification standards. There could be NO cellular sign interior the channel tunnel. provider carriers are meant to ensure.
