The Cell Phone Thread

[Riverwind (imported)]

I am with you on this one, I have a camera a real nice one it takes pictures, I have a phone I talk on it, it has other things that it does but I am not interested, I don't answer messages for two reasons, I don't know how to get them nor do I care.

My phone is just that, its mine, not some other telemarketer who thinks the best time to call is when I am having dinner. He does not pay for my phone, I pay for it, who does he thing he is disturbing me during dinner? Friends are different, friends can call at any time, but if you don't know me, there is a reason and I don't wish for you to make your acquaintance with me on my phone.

The worst of all are robo calls, this is a computer that is calling to tell you some important message that you don't want to hear, could care less about other then it disturbed you. Last week the local school sent them out for an open house, I got three of them.

I have seriously thought about doing like a friend of mine did, NO phone, you want me, come visit. Its inconvenient for everybody wanting to get a hold of the guy but he leads a nice quite life, no TV either.

Damn, well I guess I will keep the phone, but just remember if I give you my number your special.

Lot's of cell phones have "white list mode", where you can specify - accept only calls from the list. At least older Ericssons and SonyEricssons did.

As for the camera in phone - it can be a good thing, when it is the only thing you have on hand, but you just can't make decent photos, with plastic small lens. No matter how many megapixels you have . And small phone camera sensors are extremely "noisy".

Now for Moi621:

There are few kinds of magnetic/electric (they are dual after all) fields - high frequency fields: they work as a kind of microwave oven - heating tissues mostly. Don't look into the waveguide with the remaining eye .

Lower frequency - the power lines and so on - it is either mostly electric field, almost no magnetic field - like from power lines (google the image of luminescent lamps lighting up under high power transmission lines, and you will understand what happens under them, and why it is not good for you), or mostly magnetic field with low electric field - strong magnets, electric engines, power transformers and similar things.

Both can be dangerous, but, IMO, the strong magnetic fields are relatively safe (just don't carry your floppies, hard disks and credit cards through them). Ok, really strong magnetic fields, if they are localised, can disrupt your brain signalling temporarily. But for that to happen, you need really strong transients in the magnetic field.

Ok, see here//www.youtube.com/watch?v=HUW7dQ92yDU http://www.youtube.com/watch?v=B_olmdAQx5s

The first one is theory, the second one is the practical attempt to do it.

Also - magnetic field is fairly localised. Do not sleep on power transformer, not matter how warm it is, and it will be safe.

Oh, and if you feel bad near power supplies, it can be ultrasound, not the magnetic fields. I can hear some of the power supplies, especially if it is without load. The cheaper, chineese kind can have really strong level of that noise.

It is a sore spot for me, cause on previous job, I complained about the noise from the new UPS. Got "you are hallucinating" response. After that I brought an spectrum analyser app on smartphone and showed that there really was noise, in 13kHz range, and worst of all - periodic, so that you could not "tune it out".

Thank you very much.

So if it isn't a microwave oven, it is lower frequency.

I thought cell phones were microwave realm.

Please continue as inspiration takes you.

Especially the effects on biology of these lower frequency transmissions.

There goes Moi's market for aluminum foil hats. Switch to stainless steel embedded fabric and get rich.

Cell Phones are in microwave realm.

They start from 450MHz for CDMA and go up to 850/900/1800/1900 MHz for GSM (if I remember correctly).

Then there is WiFi, that strangely coincides with the frequency, that microwave ovens use at 2.4GHz and newer devices also use 5GHz, cause 2.4GHz is getting pretty overcrowded.

The power ranges start with 0.1W for Wi-Fi (or even lower) and up to 0.5W-1W for cell phones.

Okay, what is low frequency, what is high frequency and how does it effect Moi? Please.

Later we can discuss power, like a fusion reactor would be needed.

Cell phones are carcinogenic beyond baking your brain.

Thanks again

What happened to my Swiss Army Cell Phone with a tooth pick, not a blue tooth.

And a cork screw too.

BTW what did you think of those EMF shielding garments linked above?

Maybe you road to wealth? Especially the way Russians love conspiracies.

Moi,

To stop E-M radiation, AND magnetic fields copper works better than aluminum. Of course, you MUST wear a wire GROUNDING your hat to the ground or all that you may do is resonate...



Moi,

No offense intended, but you should REALLY leave science to the REAL scientists... you are continuing to belittle your intellectual self with all of the PSEUDO-science. It does NOT become an intellect of YOUR stature...

THE ELECTROMAGNETIC SPECTRUM... (http://praxis.pha.jhu.edu/pictures/emspec.gif)

Generally, all E-M radiation travels at the velocity of light, a known UNIVERSAL constant. For ANY E-M radiation, you can multiply the frequency by the wavelength and you will get the speed of light for an answer.

You can multiply the frequency by Planck's constant and get the energy of the wave OR you can divide Planck's constant by the wavelength and get the energy of the wave.

Remember, E-M radiation is ALSO conceived as a particle called a PHOTON. A photon is MASSLESS and is considered a "BUNDLE OF WAVES".

That, my friends is a concept called DUALITY... it is TOTALLY Einstein...

Remember, though. Cell phones are DIGITIZED and they SHARE the SAME DIGITAL FREQUENCY... in many cases and they DO NOT operate in real time. They operate by digital sampling. This means that they ARE to an extend encrypted. They also PING the cell phone tower(s) several times a minute. This means that EACH and EVERY cell phone can become a digital positioning device IF need be.

You can even download an app that will let you use it for digital positioning OR as a pedometer or even speedometer for your car. Sort of the ultimate electronic utensil in man's useful collection of gadgets.

Moi, go get the nexus 5. It's the hip thing to do. Tinfoil hats are not cool.

I drools over that phone.

NB: I agree with A1, phones are like modern swiss army pocket knives.

They share the same frequency (to an extent, there is a set of digital channels, each cell tower uses it's own subset from there), then, the frequency is divided by time multiplexing between the phones. That is for GSM, for CDMA it is a bit more complicated with more maths and using specific codes. Same goes for 3G).

As for encryption - yes, GSM phones are commonly encrypted (there are 3 settings there - no encryption, and two strengths of A5 encryption). Unfortunately, the encryption is not strong enough, and can be relatively easily broken.

The location functionality (without GPS) is rather crude. I have seen it at work and it can locate you up to base station. In a city, when you are located in the reception zone of few base stations, it gives you position with accuracy of few hundreds of meters. But move out of the city, and accuracy drops to the point of being useless. So what that someone knows that I am located somewhere in the circle with 10-15km radius?

I'd also add, that both SIM card and a phone have unique identifier. So, if you want to get a phone number totally unrelated to you - you need to get a new SIM, not in your name, new phone with new IMEI (or some phone with dark past ), and do not turn it on near your usual locations .
