Frying my brain daily..

Everyday, I spend around an hour talking on the phone. And, I have been doing that for the past few years. Reason is I'm too lazy to text.

I'll place the phone next to my ear (of course la, put at your butt meh?), when I'm having my conversation via my cell. Sometimes, during my conversation, I'll feel a lil' uncomfortable and I can feel the heat at my ear. I know it has to do with the radiation from the cellphone, but I've never bothered about its effect to me. Yes, I've been hearing that talking via cellphone will cause brain tumor and etc, all sort of things. But I think it is not scientifically proven. And recently, I read an article on cellphone radiation. Guess what.. the cellphone radiation is actually useful in preventing Alzheimer's disease. Read this.



Well, till now I'm still not too sure if cellphone radiation is harmful to human. But nevertheless, I have recently made a wise decision by getting myself a pair of bluetooth headset. Its from Nokia.. who don't like Nokia stuffs! Did I mention 'wise decision'? I thought I have just said that there's no proven fact that cellphone radiation is harmful, and now what? The reason I think it's good to talk via bluetooth headset is the permitted power when it's receiving and transmitting signal to the cellphone. There are 3 classes of bluetooth, which is categorized by the maximum operating range. Class 1 refers to maximum operating range of 100m, while Class 2 and 3 refers to 10m and 1m respectively. Remember this, in order to have higher operating range, the permitted power must be higher. When the power is higher, the energy involved is also higher. OK, I don't wish to go into details... To make it simple: Class1~100mW, Class2~2.5mW, Class3~1mW. As for cellphone, the power permitted is 2W. Now you can see the difference between cellphone and bluetooth's power. To make the calculation simple, assume you talk via your cell for 1 hour (=60minutes=3600seconds). The energy involved is 2W x 3600s = 7200J. If you use bluetooth headset for your conversation, here's the calculation: Class1=360J, Class2=9J and Class3=3.6J. The differences between talking with and without bluetooth is so significant!

So, which one to choose? Luckily, there's not much choice when choosing bluetooth headset. Most of them come with Class 2 bluetooth hardware. I believe it's rare to have class1 for bluetooth headset because of its power, and by the way, why do you need such a big operation range? Your phone is not walkie talkie dude. No class3 because, you don't need it when you're so close to your phone. No point having double radiation.

My advice to all of you who can't live without cellphone, please get a bluetooth headset today. You do not want to become like this:



PS: I'm not involve in any bluetooth headset distribution business. Please do not email or message me for bluetooth headsets' prices. Thanks. :D
