ACS 130 Report post Posted February 20, 2010 Use Blue tooth Headphone from Jabra and keep the Phone at least 3 to 5 meter distance. In fact Blue tooth uses far less radiation compared to Actual Handset Im also sick of 4-5 hrs of talks whole day n my age old LG 2030 / Nokia 2112 & 3125 Reliance phones.. Heats up real bad.. looking to finally shift to a Blackberry for mail & bluetooth option.. So is Jabra the best in terms of Radiation reduction OR is nokia also fine ? Jabra seems expensive..

vvinayakpai 26 Report post Posted February 21, 2010 (edited) Don't any of the lesser brand Chinese handsets come with SAR ratings? How do i find if a particular phone'a SAR rating? I am actually interested in buying that newly launch Huawei C3500. Not too aware about SAR ratings though Edited February 21, 2010 by vvinayakpai Share this post Link to post Share on other sites
ipkonfig 10 Report post Posted February 21, 2010 Interesting thread. But Nokia 1203 has a SAR rating of 1.07W/Kg, while an expensive N79 has a SAR value of 1.4W/Kg. Technically, the OP must not face any prominent problems while using the phone. If the problem persists, I would recommend seeing a doctor. Share this post Link to post Share on other sites
kshah 452 Report post Posted February 21, 2010 what ever you do, you cannot avoid radiations ! even you are not using cell phone, some one near you must be using it !, also even in air their are so many signals are active, no one can avoid them. so better try to reduce it ! Effect of radiation chages with distance. So handset closer to ears has maximum effect on user brain than passive person close by. By your logic, its true that there is so much radiation noise and polution around but distances from radiation source do matter. Wired hands-free is said to not help in preventing radiation, so beware! it helps reducing it ! Nopes. Its not that simple. The wire ends up acting like an antenna... they say it may not make a significant difference if you use it either way. Is it?? This is some thing new to me and really interesting to know. Can you please elaborate? As Hetal mentioned, I too believe that BT headsets are best to minimize radiation. I have not seen any SAR related information about BT headsets.

As Hetal mentioned, I too believe that BT headsets are best to minimize radiation. I have not seen any SAR related information about BT headsets. There are various classes of BT headsets. Class 1, 2 and 3. Class 1 BT headsets produce radiation comparable to a conventional mobile phone. You are on the safer side, if you are using a Class 2 or 3 product. 1 Share this post Link to post Share on other sites
ACS 130 Report post Posted February 21, 2010 Thanks for that info, never heard of Class 1,2,3 in BT headsets.. +1 for that surprise.. Share this post Link to post Share on other sites

Can you please elaborate? As Hetal mentioned, I too believe that BT headsets are best to minimize radiation. I have not seen any SAR related information about BT headsets. Right, I guess the inverse square law will apply. So distance is the critical parameter. People staying near a BTS would be at max. risk, I'd say. Did some searching after you asked, and found this - Studies and tests of many of the hands-free kits by scientists and consumer groups in Europe found that the earpieces themselves serve as antennae that direct more electromagnetic radiation into the ears. Phone models may differ in the degree to which their internal wires conduct electricity. But these studies find that the kits intensify radiation exposure to the ear canal, and may actually raise the amount of radiation being directed into the head by more than three hundred percent! If even the SAR ratings are not mentioned, then what is the basis of saying BT headsets radiate less? Edited February 21, 2010 by raccoon Share this post Link to post Share on other sites
kshah 452 Report post Posted February 22, 2010 Because BT emission is good for 3 meters its safe to assume that it radiate less. I don't know. if it will be more potent as its 2.2 ghz against 800 mHz of rim or 1.8 ghz in gsm new players. Gsm 3g would be 2.1 ghz Share this post Link to post Share on other sites
Sadikk 301 Report post Posted February 22, 2010 CDMA is best suitable technology for telecoms... though i dont use GSM much.. but sometimes i take calls on GSM zayed number.. and i feel how boring is to talk on GSM.. i dont know if u all will understand.. but there's something missing while talking on GSM.. like feel... dont know.. not sure..

::Hitesh:: 1,763 Report post Posted February 24, 2010 (edited) Thanks for that info, never heard of Class 1,2,3 in BT headsets.. +1 for that surprise.. when ever you buy any laser base device or BT device, check the caution on it. it is always written on back of package, Class-1/2/3 etc... also for quick reference, check your PC CD-rom or DVD-rom/Writer!!! @sadik i feel same !, after using cdma for more than 4 years (still using it), if i have to talk on gsm phone... i feel like .. it is still same when i left it!!

YOu are right sadik It is correct. I am using RCDMA for nearly 7 years and used different handsets.I even spoke for 3-5hrs continuesly but never faced headache or pain in ear. Recently started using Tatadocomo, Idea,Aircel, Uninor with nokia phone.If i speak for 10 minutes or more my ear starts paining.If i use other ear same problem after 10-15minutes. Actually i wanted to shift to GSM for better handsets.Now i am having second thought wether to shift or continue in CDMA. I have noticed that talking for long duration is convinient only on CDMA. On GSM it is very difficult to talk for more than 30 minutes. Share this post Link to post Share on other sites
ipkonfig 10 Report post Posted February 25, 2010 Ironically, two years back, when I took my first RCDMA connection I faced frequent headaches. I had taken the UL770 plan and hence my usage was heavy. Until then I had used only GSM handsets and did not face any headaches. Today I use both GSM and CDMA for extended durations. I am not facing any problems (fortunately) Share this post Link to post Share on other sites
ramtech 47 Report post Posted February 26, 2010 Wired hands-free is said to not help in preventing radiation, so beware! it helps reducing it ! Nopes. Its not that simple. The wire ends up acting like an antenna... they say it may not make a significant difference if you use it either way. I found the difference with head sets In my home RCDMA signals are weak. When I talk on LG 6600 there will be breaks in the voice. But when i use wired handsfree there is improvement in the voice clarity , there is no breakage in the voice.This is with RCDMA and LG 6600 with original headsets.I noticed this every time i use headset. Did any one else notice this.So I think headset should be working like external antenna. otheres check this and confirm. didnot check with GSM , need to buy headsets and check.

pasumark 51 Report post Posted February 26, 2010 I feel the basic problem is due to the handset and not the technology. I am using both GSM(Airtel-Nokia E51) and RCDMA( HTC Hero). I don't find problem in any of these 2 technologies. If anyone has problem, I suggest them to change the handset and try. Share this post Link to post Share on other sites
