Guys, this ain't an upgrade nor a hack issue. It is more important than all that. It is about health and how health friendly those devices are :!:
I have been hearing lots of issues about the radiation generated by either the GSM, BT or WiFi signals!
Is it true that it is not wise to carry the PPC next to the heart in the pocket or on the side pocket? Has there ever been an official report or research done on this and found it is not too friendly :?:
I know that this forum has got people from all over the globe. Therefore some of those countries might have researched and would have announced it, but mind you.. "Official Announcement
Please advise since it is a worry I've got :roll:
i've read more cases where study said that it was no problem that the other way around same thing with utms (3g)
but even if it were a problem that your hart would never be the troublesome place
your head and your testicles would be that place where it could cause issues
high watt transmision cause inc in celluar activities your hart is just a pump and need high volts expousre to react to anything like that
your brain are a pile of fat tissue where the neural transmitors and cemestry cause thinging and emotions celluar changing can be an issue there
and your semen aswell semen are preduced as a copy of the earlier produced so celluar changes which are high enough to mutate could be a problem
but cellphones are nowhere near as troublesome as highvolt lines and the wifi networks
only place you can 100% safe in in a big lead safe
Rudegar do you mean that GSM is more harmless than wifi? As far as I know the transmition power of GSM can go up as much as 2Watts in areas with low signal while wifi is only miliwatts!
wifi is always gsm is only when you make a call
i speak of wifi where you dont just use wifi at places where there are hotspots but you having a wifi network maybe some transcievers to str up the signal and such
and i also do believe that wifi is stronger then bluetooth which is just a few miliwatt dident check it though
Hello,
I'm no doctor but what I can tell you based on wireless emmissions is that if you use a bluetooth headset, and keep the device as far away from you as possible. The emmissions are reduced considerably.
A bluetooth headset has a range of 5 meters, whereas Wi-Fi or Cell Transmission are a hundred times that. Which makes me think that having a bluetooth headset near your ear, is a hundred times less strong than having a mobile phone, this gives me a peace of mind.
What is to keep in mind is that, especially during conversation. Not to leave the device inside your pocket plugged within your belt. This causes more problems as the testicles are more prone to damage than the brain is. Thus even when using the bluetooth headset. In effect its better to keep the device at a distance from your body.
Also note that using a mobile phone inside a car (especially new ones), is dangerous... Why? Because the car's shield acts as a mirror to the radio-waves. It reflects 10 to 20 times within the car, thus the radiation within the car is reflected and causing higher radiation within.. Solution? External antenna, I don`t have one, but when I use the mobile, I put it far away on the dashboard, close to the window to reflect the least radiation possible within the car. Please note that all PDA2Ks and PocketPC phones have a builtin slot to connect external antenna!
Well in fact you're right about the Lead Box.. But really, I believe that when I'm going to the beach, under the sun. Im not only getting a high dose of ultraviolet rays. Lieing down, my body is probably able to receive a 1200 channels from astra (some encrypted) and another 400 from Hotbird. Its also constantly receiving the Date and Time from GPS Satellites to calculate the location. On the other side when standing up, I'm probably getting 40 Terrestrial Channels and another 100 FM Channels. Apart from the Wi-Fi stations AND Cellular Antennas nearby.
the world is becoming clattered in radio communications. Its a must of our everyday life, the trick is to be aware of it and where possible to reduce it.
Small note about signal strenght :
The mobile's radio transmitting voltage is set according to the signal strenght.
In areas with low signal strenght, the voltage is incresed, thus increasing the radiation.

Eman

An issue not much spoken of around PDA enthusiasts is health.
after Menneisyys's most wonderful guide on how to switch between networks I would like to develop his idea in another direction which regards to your brain staying cool.
btw, here's a reference to Menneisyys's guide.
http://forum.xda-developers.com/showthread.php?t=345524
As cellular generations evolved we got the gift of fast transfer rates.
This of course, doesn't come for free, and the higher the transfer rate, the more our brain boils.. whether we're connected to the internet or not.
This is not ALWAYS true, but let's assume that the 1 in 30 cases state is negligible.
In most cases, when you're connected to the 2G network, your device will consume less battery power than when it's connected to the 3G network.
We can refer to 2G,2.5G,2.75G,3G,3.5G.. and so forth. the main issue is not the EXACT difference between these network types but how much does each of them effect your brain.
Our devices' batteries consume power. they also radiate Electromagnetic waves which, if were visible, would create a most complex web, preventing us from doing anything since we would not be able to see.
that wasn't true in the past. the amount of energy radiated was much much much lower.
When you're connected to the 2G network, for instance, your phone tries to retain a fluent connection between its receiver and the (usually) closest relay point. this requires power. this power is also reflected into your brain.. and while a small % of it is dissipated into the air, a lot of it creates unnatural (we'll leave it at that) heat in your brain. it's something like the heat emitted from laptops (which you should also keep a good distance from.. using coolers and stuff.. or you'll get all kinds of pains.. like i have right now typing this on my laptop).
Every provider plants relay points in different places.
though it's a common belief that those relays are not healthy for you and you'd want them as far away as possible.. i'd say you don't.
it's true that having a relay 15-25m away from your window isn't exactly a vladnik carnival but there's a certain distance from the relay in which your phone wouldn't work too hard to retain a signal, and the relay (edit: not the actual relay but the effects caused by having a close relay) won't keep your neurons busy until they burst. It is obviously impossible to individually control the distance.
As 2G and 3G have different requirements, they also have different power consumption. It doesn't require much more than common logic to understand that since 3G needs to transfer more data during a short period of time, it would use more resources than 2G, which needs less during the same period.
As an introduction to the concept of "power" i'll begin by saying that 2G requires something about 3-5 times less the power to keep a live connection than 3G does. as it's not completely true, it wouldn't be wrong to say that 3G creates about 3-5 times the heat than 2G does. a fireball to your brain.
Rough numbers are averaging from 0.043mW/kb in 2G to 0.23mW/kb in 3G.. while using EDGE for instance... is much closer to 2G than to 3G.
Power dissipates by 1/r^2, r being the distance, so i'd say it's certainly fitting to use a headset rather than talking straight to your device.
of course, the best thing to do is to use your speaker.
1. You will be wise using 2G only for phone calls and use your speaker as much as you can to keep yourself away from long lasting brain damage.
2. You will be wise to use NOT MORE than the EXACT data connection you need for your applications. (i.e. if EDGE is fast enough for you, DON'T use 3G)
3. Actually, you will be wise NEVER to use 3G... but that's a bit hard for people who download porn on their devices and want 1.8-14.2MBPS
4. Cancer isn't a joke. BELIEVE me..
5. Cancer isn't a joke.
I'll finish by helping you understand how bad the whole issue is.

the power formula is P=I*V
in the 2G case, P=0.091*3.9=0.355W
in the 3G case, P=0.239*3.9=0.93W
the relative power is 0.93/0.355 = 2.62
this means that at my house, where there is almost maximum signal strength, 3G requires about 2.6 times the power 2G requires.
these are really rough numbers as the current also contains other factors... but you can see the general ratio.
now when the signal is low, 3G requires like 3-4 times more than required when there's a strong signal.. but 2G only requires like twice.. maybe less.. since it has a much lower transfer rate.
it is true that this is the power used and not the radiated power.. and it's true that there's distance between the battery and your brain.. but roughly..
3G is HORRIBLE. don't kill yourselves. use your phones. wisely.
- never use more than 2G unless required. 2G supplies EVERYTHING you need but video calls and internet services at the same quality.
- never use more than EDGE unless required. EDGE supplies about 300kbps which is good for surfing..
- never use 3G unless you really need a very fast connection.
you are invited to use the below tools to check how your phone acts.
Hope this helps you realize what's good for you.
EDIT: now just to clarify this issue so that i don't get clobbered, i am NOT refering to electromagnetic waves THEMSELVES (thus canceling the effect of distant electromagnetic radiation emitting devices). all i am refering to is the heat generated by your device. electromagnetic waves have yet to be proven harmful since their frequencies are too high to harm us(that's the current assumption). the heat generated by those waves tho, is known to "fry". that is, and as i mentioned before, like the heat generated from your laptop which causes inflammations.. and .. other things.
There IS a link between the electromagnetic radiation to the heat generated in our body as the higher the frequency, the higher the particle velocity, causing higher friction which causes heat. this effect is negligible when discussing distant electronic devices, since, as i said ealier, power dissipates by 1/r^2.
what i'm trying to say is, that whether it is proven you can be harmed from electromagnetic radiation and heat or not, we should just be cautious. just in case..
Well.... first of all I do not agree on all your points or think everything you say is as serious a factor as you describe it to be. However, I'll not 'bicker and argue' on these points, less radiation is always better, after all.
In fact, you just gave me an idea for an awesome new app, I may or may not write soon
The whole reason for my reply however is this simply tip that will make a lot of difference for a fair number of people, I'll bet:
Do NOT place the phone next to your head next to your bed when you go to sleep!
This was actually in the news here either past week or the week before that. Seeing as you'd be in that position for like 8 hours, you can see how it can make a difference
You are correct. this isn't as bad as i made it sound. but making something sound worse than it is always makes people take it more seriously.
I would say that the problem isn't really in the short run.
In the long run, it can be devastating.
and you're right. it's a good tip to not leave the phone close to your head while sleeping.
this actually creates unwanted brain activity. again, in the short run.. it doesn't really matter.. but having more current going thru your brain EVERY night.. will damage it.
and by all means.. argue. this is a forum after all
Surely it's your gonads that are in more peril from 3G as I don't surf/videocall with the phone against my head?
I guess yeah your gonads may be in trouble
Personally I don't even have phones in the same room as where I sleep, and whenever I'm not walking somewhere they aren't on me either. In the car they're either on the passengers seat or in the glove-box, and at home or work they are in their desktop cradles
Dont carry them on you unless you have to.
Interesting read...nir36!
One thing is for sure, numbers don't lie. As you know, my thread question whether 3G is worth it on a battery front, but more importantly on a health front.
It would be great to get an APP to allow Communication Manager to speak to the different Networks (2G, 2.75/Edge, 3G, 3.5G, etc.) in order to give back power to the people...instead of power going to their heads!
Yes, I know people use the internet away from their heads but most use the 3G network for phone calls. I don't......switch to Edge immediately.
As mention previously, it would be great to have a "Network Switcher" allowing users to make wise choices.
I leave my data connection running downloading stuff a lot of times when I am at work. I have found I can amp the juice down a LOT by turning on my speakers and listening to the crazy noise then moving the phone to a spot where the noise goes away or gets very quiet. For instance. On my desk they go crazy. If I put the phone on the window they go silent very where as moving it in the other direction the same distance does nothing. My conclusion? my head and the speakers which are only about 2 feet away from my head are getting much less radiation. Can do the same thing with my headset for a more accurate placement BUT for some reason it barely picks up the signal to begin with. Not to mention the cold metal window sill cools the phone! bit torrent gets the lil bugger warm.
hey and what if i disable GSM module for night? i use my pda also as alarm clock so is it also so dangerous when it is disabled but still near my head when i am sleeping?

if Phone, Wifi, and Bluetooth are off in the wireless menu I cant see of any reason it would emit any radiation. Unless someone else knows something I don't.
Putting it in "flight mode" would indeed kill 99% of all radiation.
as Chainfire said.. it would kill about 99% of the radiation.. or even more.
radiation levels are caused mostly by the fact that you have an antenna fixed in your device which emits EM waves heretically while the phone is on. when the Bluetooth, Wireless and Phone are off... the device only runs on a few mA... while in sleep mode... so the heat levels are dissipated at about 0.05 (or so) cm from the battery. even if you put your phone right next to your ear while all comm services are off.. there's almost 0 chance that something would happen.
to answer your question... a pda in flight mode acting as an alarm clock can be placed next to you. still, just in case.. keep it 20cm from your head.
Wouldn't it be great if a manufactuer built a phone with a small parabolic reflector behind the antenna that very quickly rotated based on the direction of the tower. Increased battery life. Increased signal. Decreased radiation through your head. Sounds difficult at first but when you think about it, it would be pretty easy and cheap.

I did spend some time on cooking something up that will reduce power usage for GSM-based devices when you're not 'manually' using the data connection. Not nearly done yet, but I have to be off for the weekend so it'll be a bit longer too.
When it's done it will result in your brain (and gonads!) being cooked less, as well as longer battery life. So longer life for both you and your battery - you may place your bets on what it will be called now!
I think it will be called, "Chainfire's Gonad Savior"

lol. good idea. if only we had x-ray vision
Given that the OP here mentions cancer and 'brain boiling' and all sorts of other horrific stuff but doesn't appear to have any real science backing these claims up, isn't this thread just rampant scare-mongering?
Its highly overstated to make a point. This just proves you didn't get that point
Besides, how radiation works and what it can do is widely known. If you have to provide scientific proof of every widely known thing whenver you talk about it ...
Here's a puzzler.
I recently started using my automotive GPS again (Garmin Nuvi 1450; same as the 1490) but I've noticed it's acting haywire whenever my Inspire is even close to it. For example, the accuracy becomes off by miles and it thinks the elevation is roughly 3000 feet when the elevation of the area I live is 150 feet above sea level.
Suspecting something, I powered off my Inspire and the Garmin immediately went back to being dead accurate so it has to be something with the Inspire.
I run my phone with WiFi and GPS disabled, I live in a HSUPA enabled area and my phone is set to use all available bands; it's generally in HSUPA mode. The rom I'm using is based off the Cyanogen nightlies, LorDmod kernel, 12.54.60.25U_26.09.04.11_M2 radio.
If anyone's experienced something similar or has any potential fixes that would be great. Putting my phone on airplane mode every time I get in my car isn't a very viable solution.

Have you tried Garmin Customer Support? It sounds like the problem is possibly with the Garmin, and not the Inspire. A stand alone GPS unit should be able to withstand interference form a cell phone, IMO...

It doesn't happen when my brother's Thunderbolt or my old iPhone 4 is around it so I'm kind of confused. I haven't called up Garmin yet, just noticed it going haywire today, but I'll give that a shot.

Yeah weird problem if only confined to the Inspire device. I have noticed for YEARS on AT&T with multiple handsets (including the iPhone) that something with the native signal interferes with the landline phones and some computers with stand alone speakers in the form of static and beeps that make it sound like I am trying to contact the Mother Ship...only at my employers cubes though...

GPS frequencies are at approximately 1227 and 1575 MHz. The Inspire cell phone radio transmits in the 850, 900, 1800 or 1900 MHz bands depending on whether it's using EDGE, 3G, etc. So in theory it shouldn't interfere, unless some weird harmonic frequency situation is going on. You didn't say if you're using bluetooth, but these frequencies are in the 2400+ range (close to the WiFi range), so once again there should be no interference. It may be worth turning it off just to see (if you haven't tried this already).
Since the other 2 phones you mentioned don't cause the same problem, this does potentially point to your Inspire as the source. Maybe for some unknown reason your Inspire is poorly shielded (possibly due to some sort of defect during assembly) and is therefore spitting out more interference than it should. Or your radio is not running within spec due to some sort of hardware or software issue, and is spitting out spurious interference.
Personally I would try flashing the stock radio version 26.06.06.30. This is the stock radio that is FCC approved to run on the Inspire, and therefore has passed the FCC testing and certification for spurious signals, interference, etc. Get the version that comes with the RCData file, in the radio thread in the dev section.
One more thing to check: make sure the cell antenna (built into the inside cover of the SIM/SD cover at the bottom of the phone) is making good contact with the phone when the cover is on the phone. Look for the little gold contacts, and make sure they are clean and sticking up slightly with a "springy" tension to them, so as to make good contact. The reason I say to check this, is because if your antenna isn't connected 100% properly, the cell radio may increase its transmission power to compensate, which might also increase the interference it creates. This is pure conjecture.
What about Bluetooth?
Took too long. Just listen to Henry. He's a friggin genius. I think. He always seem to help me.

Yar, that's the GSM signal interfering with electronics (usually cheap speakers) that aren't properly magnetically shielded against the GSM frequencies AT&T uses.
EDIT:
@biglittlegato - Good question, I always leave bluetooth disabled as well; I never use it. So much so I forgot this phone supported it. Heh.
@henrybravo - Cheers. I'll reflash back to 26.06.06.30 with the RID and see what happens.
EDIT2:
Also fired off an email to Garmin as well. Their response time window is 3 days so we'll see what they say as well.
The odd thing is that it was working fine when I drove to work this morning. Maybe it has something to do with the network load. Bleh, I'm just throwing stuff out there at this point.

That all makes sense . Rather annoying when on the land line phone with someone at work though, or worse, we have an overhead paging system, and the beeps and static kick in when I'm on the overhead...just blame my employer's choice of inexpensive hardware and not fault my phones or cell service though .

Sent from my Inspire 4G™ using XDA Premium App
Cheers for your guys' help in this matter. There were a few updates for the nuvi that Garmin sent me and I flashed the 26.06.06.30 radio and the issue seems to have dissipated. Still not sure what exactly fixed it or if it was just a GPS reading fluke but all is well now.
I was thinking about this for android since it's an open system but it probably applies to any phone once you XDA guys get them.
The idea is that since there is a Cell Phone radio in the phone, and there is a possibility to gain access to that radio is it possible to create a DOS attack in an area using just a normal cellphone? Imagine having an app to effectively block communications for what would probably be a very small area to keep it going long enough.
Does phone hardware even have the capabilities to do this?
Hypothetically, it should be possible, though I'm unsure of the level of access to the radios themselves in any phones...If you can get the radio to output noise on all frequencies constantly, with enough output, you should be able to jam a small area. However, the biggest issue (after gaining access to the radio chipset at the lowest level) would be pumping out enough power across the different channels to degrade others' reception.
You could probably get away with pumping out noise in intervals (extending battery life from your handset) and still degrade a signal enough to disrupt communications.
However, encrypted signals may be able to overcome brute-force jamming to a certain extent...I'm not sure if cellphones use spread-spectrum or frequency hopping, but if they do, there's another issue to overcome.
Keep in mind, if anyone clues in to the jamming, law enforcement radio direction-finding equipment will pinpoint the jamming headset pretty quickly, since you need to output a more powerful signal for your jamming to be effective.
cell phone jammers are also highly illegal.
It was a thought that came to my mind and I understand they're very illegal but I was wondering. Mostly for the capabilities of our phones, mostly the android ones.
I think it's a pretty interesting topic. Not sure I've ever heard anyone think of this one before on the forums (I don't post a lot but I read a lot)
only government officials can use cell jammers in case of bomb threats and stuff like that
You can buy jammers online if you know where to look for peanuts. Outside the USA some places have been using them as casually as in theaters. I also heard similar reports in hopitals but that surely has to be rumour mill since the whole point of no phones there is to reduce electromagetic interference messing with equipment like in planes so why would you spam with even more? (I think jammers DDOS the airwaves rather than anything much intelligent?).
The modem section of android has AFAIK always been closed source. This put a spanner in the works for things like the Replicant project which was trying to build a truely transparent phone open source so that you always know what is going on and have some privacy. The furthest they got was pretty much everything apart from the modem open source and that modem was able to spy on everything else.
Basically the network owners want a tight rein on what's connecting to their networks and the spectrum licensees want control of the spectrum. This is something both have at the moment legally...
but what with software defined radio like GNU Radio is pretty impossible to enforce and the only thing delaying this change is the economics of software defined radio and it's size. I expect this will change over time and that could be another very disruptive and interesting technology. As such I expect it'll try to be repressed making the problem worse.
That said, there are plenty of modems now for Arduino like projects and I'd expect just one of these to be open source?
Hope this helps clear it up for you

I have noticed this for nearly every device I have owned. The laptop will always seem to catch a better signal than the phone, even though they are both in the same position, same network, etc.
Is there anything I can do to boost the signal range of my phone?
(no I'm not sticking an antenna on it)
Interesting - I notice the complete reverse. My doubleshot has stronger signal to my wifi router and for a longer distance (of about 5 feet in my driveway) then my laptop.

Out of all the different phones I have owned, NONE have been able to catch wifi signals as good as my laptop
As I speak right now, I am connected to the same network with both devices. Laptop shows a good signal, while the phone is showing a poor signal, and even disconnects at times.
Interesting. I guess logic might wanna tell me that a laptop would have a larger/more powerful radio chip, or whatever it is that receives the signal... and that has basically been my experience, my laptop can stray further away from the router. But perhaps it depends on your hardware?

Yes this has been the case from my G1 all the way til the DS.

I have to think the same. That has been my thinking since I started brainstorming ideas about this. It would be interesting to see a answer with facts tho. :thumbup:

Well, my laptop is about 2 years old and beat up, compiling kernels is killing it.
I wouldn't be surprised if the wifi chip suffered some damage from how many times its overheat and shut off.

I have this same problem, out of all my devices my Doubleshot is the worst at picking up a wifi signal. This includes two other low end Android phones, the Droid Eris, and the Huawei Ascend. On my Ascend I can pick up my neighbors wifi almost anywhere in my apartment, even better than my laptop, but on the Doubleshot I can not pick up the signal at all unless I am outside right next to my neighbors house. I wish there was a fix for this issue. Even at school where the wifi is very strong, I can only pick up a weak signal that disconnects from time to time on my Doubleshot, but my Ascend never had that problem, it always received the signal strong and clear.

My laptop is nearly 4 years old. Runs a Centrino chipset. Maybe that explains the better signal it catches. Either way, I've never seen a phone outperform a laptop in signal strength

lol - you should come by my house. Sometimes (I posted it in a thread a few months ago around here somewhere) I use the doubleshot as a wifi bridge to my router to make up for the inadequacies of my laptop wifi abilities, or for my desktop that has no other means of internet connectivity.
It seems I represent a minority (of one!) in this... i dunno. I've been excited about how well it works out, and am quite surprised (astonished even!) to find everyone else singing a different tune.

Yea, seems like you're the only one. By the way, if your laptop is overheating from compiling, you're doing something wrong. No laptop should overheat, even under full load, unless you have blocked vents, or you're overclocked.
Lol, unless it's choked with dust, has no compound between the processor and heatsink, the fan doesn't work and it relies on an external cooling pad for all of it's cooling air circulation.
Half the usb ports are burnt out and no longer function and the speakers stopped working a year ago. Since the audio out jack has stopped functioning.
I'm pretty impressed with the fact that it even still turns on, let alone being able to actually do anything with it, but, I'm hoping to get a full blown linux install on the doubleshot and thereby circumvent ever having to purchase a real computer again.
I'd grab another laptop, but, i'd rather invest my limited tech funds into android hardware and write off real computers entirely, and given the capabilities of the doubleshot and future android devices on out this is no pipe dream - the only thing between me and realizing that goal is the knowledge to make it happen, a gap that shrinks daily.
