1) How can I Reduce the mobile radiation without affecting the effective mobile communication ? .
2)How can I Reduce the specific absorption rate (SAR) of bio-tissue of electromagnetic radiation found in cellular communication ?

Dear Omniea,
welcome,
May be the major effort must be directed to reduce the radio frequency dose incident on the body of a human. This can be accomplished by reducing the power of the source of such radiation. This a matter of the communication system design issues. I do not know whether you are a communication engineer of which is your specialization. There are some methods to reduce the radiated power from the base stations while keeping the achieved data rate constant. The most effective method is using MIMO systems.
The other solution may be to decrease the area covered by every base sations. this will reduce much the power radiated since the distance is proportional to square root of the power.
May be one of the most serious sources are the mobile terminals themselves as most of them are handheld. especially when one makes a talk.
There are some precautions that one uses to reduce his subjection to the rf radiation as to communicate hand free through blue tooth devices.
The other issue is the biological effects of such radiation on human tissues. There are many studies on such biological effects of the rf radiation on the human body.
Best wishes
Dear Omniea Othman el Hoseny ,
An indirect initiative will be the concept of small cells with millimeter wave communication in next generation wireless communication, they need to use small power levels for small cell radius (coverage ares). The effective radiation level will be then reduced.

Dear Omniea,
One of the best solution is the concept of small cells and distributed base station architecture in the next generation, this architecture tends to use low-power nodes small cell to cover small areas. This is also efficient with millimeter wave communication. The exposure to network radiation will be significantly reduced compared with large scale antennas.
I refer you to my paper:
Reducing the Exposure to Millimetre Wave Radiation Using Distributed Base Stations in C-RAN Architecture:
https://www.researchgate.net/publication/328368576_Reducing_the_Exposure_to_Millimetre_Wave_Radiation_Using_Distributed_Base_Stations_in_C-RAN_Architecture
If you'd like, I can share the paper privately.
Best Regards,
Naser
I think it depends on the location of the base station and its height as the beam forming techniques will play important role also
I major way is to ensure the receiver pick his or her calls before placing the phone close to your ear for conversation.
