(there are real numbers out there, but one has to do field strength to power conversion and that assumes an antenna of some sort...) and assuming same materials would work about the same at 900 MHz, it seems like the attenuation may be in the range of 30 to 50 db. => SO if one lives near a Cell tower, it may work fine, if one is 10 or more miles away, perhaps not. the dynamic range on tower to cellphone is about 120 dB, (gets complicated, 30 watts out into 120 degree antenna, pathloss, sensitivity floor of cellphone, and then the reverse path, as cellphone has perhaps 5W out) (subtract 40 db of the chamber from the 120db working range of cellpone/tower)
