Interference of fibre optic signals with mobile phones' microwaves?

Click For Summary

Discussion Overview

The discussion revolves around the claim that the inability to make a phone call in certain environments, such as trial rooms or bathrooms, indicates the presence of a hidden camera due to interference from fiber optic signals. Participants explore the logic behind this claim and share personal experiences related to mobile phone signal disruptions.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants express skepticism about the logic of the SMS claim, labeling it as "stupid" or "BS."
  • One participant notes that mobile phones can experience signal disturbances when near other electronic devices, suggesting a possible engineering explanation.
  • A personal experience is shared where a phone call was disconnected quickly in a crowded elevator, raising questions about environmental factors affecting signal strength.
  • Another participant mentions that being in a metal box, like an elevator, can lead to immediate signal loss due to the shielding effect of the metal.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the SMS claim, with multiple competing views on the causes of mobile phone signal disruptions. The discussion remains unresolved regarding the relationship between fiber optics and mobile phone interference.

Contextual Notes

Participants acknowledge personal experiences and observations but do not provide a unified explanation for the phenomena discussed. There are references to specific conditions under which signal loss occurs, but these are not fully explored or agreed upon.

I got an SMS educating people how to find out the presence of a hidden cam in a trial room of a textile showroom or bathroom. It goes like this :- "If you can't make a call in the room,the there is a hidden cam. This is due to the interference of the fibre optic with the signal transfer." Strangely enough, this is a popular SMS . But I can't quite find a logic in this and the whole thing seems stupid to me. Anyone care to contribute their thoughts on this?

As it stands, the message does,indeed, seem stupid.
 
I can't be sure enough to counter comment on this subject as it is not a subject of my concern (fibre optics) but i knw one thing that mobile phones do get disturbed due to a closely located electronic device capable of transmitting signals! say for example, when your phone is kept near to your pc or a lapy, you get disturbances, there might be an exact reason behind this in our engineering terms, but I would like to share one more thing, that to my surprise, before posting this, I have personaly experienced this problem while in a Mall when I was in D lift, well equipped with a close circuit camera! that might be due to the congested environment of the lift as well but, the point is, a phone requires atleast 10 sec to loose network, but it happened within 2-3 seconds that my call was automatically disconnected, so its worth trying dude!

Using "u" instead of "you", etc. I will fix up your post. Please avoid cell phone txt message abbreviations here on the PF. They are against the rules (please see the Rules link at the top of the page).

If you step into a metal box (like an elevator), you can lose your signal immediately because of the shielding effect of the metal box.
