Re: Electromagnetic radiation and its effect on the brain
Well , while that is true , knowing IMEI will not reveal enough data to track a cell phone , you will need another component , which is called triangulation.
Lets suppose that you have a mobile phone without GPS option , an old one , they still know where you are.
When your cell phone logs into a network , in fact one of (for ex. 3 - depending on implementation ) surrounding BTS (Base Transciever Station) , it will connect to the nearest one. BTSs are situated in a triangle , which form a cell. Now , getting reading from all 3 BTS towers will pinpoint exact (+ - 10 meters - maybe better nowadays) location of target mobile phone.
So nowadays , only way to avoid being tracked is :
- take battery out of the phone - if you have iPhone - you fail :D
- be anonymous from the beginning - buy prepaid SIM card with brand new phone
- Combination of above example and cloning of an IMEI
Each cell phone and it's SIM card has a unique number called the IMEI and IMSI respectively and so knowing it's position shouldn't be a problem, isn't it?
