Kedu ihe bụ ule SAR?

SAR, nke a makwaara dị ka Specific Absorption Rate, na-ezo aka na ebili mmiri electromagnetic etinyere ma ọ bụ rie n'otu akụkụ anụ ahụ mmadụ. Nkeji a bụ W/Kg ma ọ bụ mw/g. Ọ na-ezo aka n'ọnụ ọgụgụ nnabata ike a tụrụ atụ nke ahụ mmadụ mgbe ekpughere ya na oghere electromagnetic ugboro redio.
Nnwale SAR bụ nke kachasị maka ngwaahịa ikuku nwere antenna n'etiti 20cm site na ahụ mmadụ. A na-eji ya echebe anyị na ngwaọrụ ikuku gafere uru nnyefe RF. Ọ bụghị eriri mgbasa ozi ikuku niile dị n'ebe dị anya 20cm site na ahụ mmadụ chọrọ nnwale SAR. Obodo ọ bụla nwere usoro nnwale ọzọ a na-akpọ nyocha MPE, dabere na ngwaahịa na-emezu ọnọdụ ndị dị n'elu mana nwere ike dị ala.

Mmemme ule SAR na oge ndu:
Nnwale SAR nwere akụkụ atọ: nkwado nhazi, nkwado sistemu na nnwale DUT. N'ikwu okwu n'ozuzu, ndị na-ere ahịa ga-enyocha oge nlele ule dabere na nkọwa ngwaahịa. Na ugboro ole. Tụkwasị na nke a, ọ dị mkpa ịtụle oge ụzọ maka akụkọ nyocha na asambodo. Ka a na-achọkarị nnwale ugboro ugboro, ka a ga-achọ ogologo oge nnwale ahụ.
Nchọpụta Xinheng nwere akụrụngwa nnwale SAR nke nwere ike gboo mkpa nnwale nke ndị ahịa, gụnyere mkpa nnwale ọrụ ngwa ngwa. Na mgbakwunye, ugboro ule na-ekpuchi 30MHz-6GHz, ọ fọrọ nke nta ka ọ kpuchie ma nwee ike ịnwale ngwaahịa niile dị na ahịa. Karịsịa maka mgbasa ozi ngwa ngwa nke 5G maka ngwaahịa Wi-Fi yana ngwaahịa 136-174MHz dị ala n'ahịa, Nnwale Xinheng nwere ike inyere ndị ahịa aka idozi nsogbu nnwale na asambodo nke ọma, na-enyere ngwaahịa aka ịbanye n'ahịa mba ụwa nke ọma.
