Ukuqonda izimiso eziyisisekelo zengqalasizinda yokuxhumana engenantambo kubalulekile kochwepheshe bemboni. Isihloko samuva nje sobuchwepheshe sinikeza incazelo ebalulekile yokumbozwa kwesignali yesiteshi esiyisisekelo kanye nezindinganiso zokuphepha eziqinile ezilawula ukuchayeka emphakathini, izihloko ezibalulekile ekusetshenzisweni kwenethiwekhi kanye nokwethenjwa komphakathi.
Lesi sihloko sicacisa iphuzu elivamile lokukhathazeka komphakathi: uhlobo lokukhishwa kwegesi esiteshini esiyisisekelo. Sihlukanisa lezi zimpawu ze-radiofrequency (RF), ezingakhiqizi i-ionizing, ezinhlotsheni zemisebe enamandla kakhulu. Incazelo yobuchwepheshe eyinhloko igxile kuukuncishiswa kwesignali—ukwehla okusheshayo kwamandla esignali ngebanga. Ngenkathi i-transmitter yesiteshi esiyisisekelo kanye ne-antenna kungahlangana ukuze kutholakale amandla akhishwa kahle asezingeni eliphakathi kuka-56-60 dBm, la mandla ayanyamalala kakhulu njengoba ehamba esikhaleni futhi exhumana nezithiyo zemvelo. Njengoba kukhonjisiwe, ebangeni elingamamitha ayi-100, ubukhulu bamandla buvame ukwehla bube yi-minuscule -40 kuya ku-50 dBm, bunciphe kakhulu bube yi--80 dBm kumamitha ayi-1,000.
Into ebalulekile oyifunda kulesi sihloko ukuthi imithetho yokuphepha kazwelonke iqine kakhulu. Iphawula ukuthi iShayinaIzinga elijwayelekile le-GB 8702-2014ibeka umkhawulo wokuchayeka emphakathini webanga lemvamisa yokuxhumana ku-40 µW/cm². Ngomongo, lo mkhawulo uqokonyiswa njengoqinile ngokuphindwe ka-15 kunendinganiso yase-US efanayo. Ngaphezu kwalokho, imboni ivame ukusebenzisa isici esengeziwe sokuphepha, lapho opharetha benethiwekhi bevame ukuklama amasayithi okusebenza ngengxenye eyodwa kwezinhlanu zomkhawulo kazwelonke osuvele ukhona, okuqinisekisa ukuthi kunesilinganiso esikhulu sokuphepha ukuze umphakathi ubonakale isikhathi eside.
Amaqhawe Angadumile Okusebenza Kwenethiwekhi Nokuthobela Imithetho
Ngale kwe-antenna, ukusebenza okuthembekile, okusebenzayo, nokuhambisanayo kwesiteshi ngasinye sesisekelo kuncike ekuqondeni okunembileizingxenye ze-RF ezingasebenziLawa madivayisi, angadingi amandla angaphandle ngokwawo, ayisisekelo sokuphatha ubuqotho besignali ngaphakathi kohlelo.izihlungizibalulekile ekuhlukaniseni amabhendi athile emvamisa nokunciphisa ukuphazamiseka, kuyilaphoama-duplexervumela ukudluliselwa kanye nokwamukelwa ngasikhathi sinye ku-antenna eyodwa. Izingxenye ezifana ne-antennaabahlukanisi bamandla,ama-couplers, futhiizihlukanisilawula ngokunembile, uqondise, futhi uvikele izifunda ezibucayi ngaphakathi kweketanga lokudlulisa.
Kusekuklanyweni nasekukhiqizweni kwalezi zingxenye ezibalulekile laphoI-Chengdu Concept Microwave Technology Co., Ltd. isebenzisa ubuchwepheshe bayo. Njengomhlinzeki okhethekile we-microwave engasebenziizingxenye, Iphothifoliyo yomkhiqizo we-Concept Microwave isekela ingqalasizinda eqinile edingwa amanethiwekhi esimanje e-3G, 4G, kanye ne-5G. Ngokuhlinzeka ngezingxenye ezisezingeni eliphezulu nezithembekile ezenzelwe ukuzinza kuzo zonke izimo zemvelo kanye nokushisa, inkampani inegalelo ekwakheni amanethiwekhi angenantambo azinzile, asebenzayo, futhi ahambisana ngokugcwele akha umgogodla wokuxhumana komhlaba wonke.
