Tower Power density is power per unit area. ICNIRP guidelines set density limits for occupational exposure and the public. For the public using GSM mobiles the limit has been kept at 4.5 W/sq m for 900 MHz and 9 W/sq m for 1,800 MHz. For CDMA phones it is 4W/sq m. Occupational exposure limits are five times the public limits. Mobiles Strength of the mobile signal determines the

Mobile phones, like radios, rely on radio frequencies to communicate. They operate at 800, 900 and 1,800 MHz, which are also referred to as microwaves. In the electromagnetic spectrum they fall between radiowaves and infrared rays. Mobile phones
