Can smart phones be shielded from mobile phones?

2018-07-05 15:40:08

Answer: there is no way. Cell phone is not shielded from mobile phone and intelligence is not related.

GSM mobile phone frequency is 900MHz/1800MHz, CDMA is 800MHz, PHS is 1900MHz, cell phone signal shield is usually the frequency of these four frequency interference shielding, if you have a way to make the cell phone not in this frequency within the circle can not love the interference, so there is no way, because if the cell phone is not in This frequency is not mobile phone (including PHS).
