What are the best specifications and determinants used in reducing electromagnetic pollution emitted from mobile phones and towers?
Dear Hayder,
A good Rf planning could help to arrange the towers in a proper way, employing towers on high attitude with a nice titling. at home it is better to reduce the wireless transmitter as possible especially at night for family mental and health safety.
To have best specifications you should check out the ITU propagation letters, because the specifications are deferent from system to system and from generation to other generation of mobile communications. HAPS Technology could effectively reduce the harmful signals especially those coming from side and back loops of antenna, if a system of towers replaced by HAPS.

As it is well known that the users of Mobile phones use their phones in touch with ears (This means that the mobile phones are in touch with brain during every call and thus the electromagnetic radiation will have a great influence on the brain). The traditional antenna that is usually used for mobile was a simple wire antenna (or dipole) which receives or transmitters radiations to all direction equally (of course including the head side). Thus, with this traditional type of antenna there exist a risk on the brain. To reduce such risks, the current technologies for mobile phones include designing an antenna with receiving or transmitting radiation patterns that are relatively far away from brain side to keep as much as possible the brain far from radiation pattern of the mobile antenna.
For tower sides, they usually try to use minimum radiated power especially on the region that is very near or around the tower position.
Optimizing radiated power is a bit more complicated than increasing towers altitude and tilt angle because the far is the tower the higher will be the power that a single phone has to radiate to stay in contact with the net.
Towers are designed to use minimum radiated power not (or at least not mainly) for safety reason but to save energy and reduce interference.
Near to the tower, the field on the ground is normally low due to the radiation pattern designed to cover a wide area
Hello,
I agree with the aforemementioned and I should add that taking advantage of free space path loss then someone should hold his mobile phone at least 5 cm far from their ear on the condition that the interlocutor is heard in that distance and no indiscreet people are nearby. In this way even the unwanted low radiation lobes would not contribute to a high radiation towards brain.
Best regards
