Ukuqonda imigaqo esisiseko yeziseko zonxibelelwano ezingenazingcingo kubalulekile kwiingcali zoshishino. Inqaku lobuchwephesha lakutshanje libonelela ngohlalutyo olubalulekileyo lokugubungela isignali yesitishi esisezantsi kunye nemigangatho yokhuseleko engqongqo elawula ukuvezwa koluntu, izihloko eziphambili ekusetyenzisweni kwenethiwekhi kunye nokuthenjwa koluntu.
Eli nqaku licacisa ingongoma eqhelekileyo exhalabisa uluntu: uhlobo lokukhutshwa kwegesi kwizikhululo ezisisiseko. Liyahlula ezi signali zerediyo (RF), ezingayiyo i-ionizing, kwiintlobo zemitha enamandla ngakumbi. Ingcaciso yobuchwephesha ephambili igxile kuukuncitshiswa kwesignali—ukwehla ngokukhawuleza kwamandla esignali ngomgama. Nangona i-transmitter yesikhululo sesiseko kunye ne-antenna zinokudibana ukuze kufumaneke amandla asebenzayo akhutshwayo kuluhlu lwe-56-60 dBm, la mandla ayaphela kakhulu njengoko ehamba esibhakabhakeni kwaye edibana nemiqobo yokusingqongileyo. Njengoko kukhankanyiwe, kumgama weemitha ezili-100, uxinano lwamandla luhlala luhla luye kwi-minuscule -40 ukuya kwi-50 dBm, lunciphe ngakumbi luye kwi--80 dBm kwi-1,000 yeemitha.
Into ebalulekileyo ekuthethwa ngayo kweli nqaku kukuba imithetho yokhuseleko lwesizwe ingqongqo kakhulu. Iphawula ukuba iTshayinaUmgangatho we-GB 8702-2014imisela umda wokuvezwa esidlangalaleni kuluhlu lweefrikhwensi zonxibelelwano kwi40 µW/cm². Ngokwemeko, lo mda ugqanyiswa njengongqongqo ngokuphindwe kalishumi elinesihlanu kunomgangatho ofanayo wase-US. Ngaphezu koko, eli shishini lidla ngokusebenzisa enye into yokhuseleko, apho abaqhubi benethiwekhi badla ngokuyila iisayithi zokusebenza ngesinye kwisihlanu somda wesizwe osele ugcinwe, ukuqinisekisa umda omkhulu wokhuseleko lokuvezwa koluntu ixesha elide.
Amaqhawe Angadunyiswanga Okusebenza Kwenethiwekhi Nokuthobela Imithetho
Ngaphaya kwe-antenna, ukusebenza okuthembekileyo, okusebenzayo, nokuvumelanayo kwesikhululo ngasinye sesiseko kuxhomekeke kwisuti yokuchanekaizinto zeRF ezingasebenziyoEzi zixhobo, ezingadingi mandla angaphandle ngokwazo, zibalulekile ekulawuleni ukuthembeka kwesignali kwinkqubo.izihluzizibalulekile ekuhlukaniseni iibhendi ezithile zefrikhwensi kunye nokunciphisa ukuphazamiseka, ngelixaii-duplexersvumela ukuhanjiswa kunye nokwamkelwa ngaxeshanye kwi-antenna enye. Izinto ezifanaizahluli zamandla,ii-couplerskunyeizihlukanisilawula ngokuchanekileyo, uhambise, kwaye ukhusele iisekethe ezibuthathaka ngaphakathi kwekhonkco lothumelo.
Kukuyilwa nokuveliswa kwezi zinto zibalulekileyo aphoI-Chengdu Concept Microwave Technology Co., Ltd. isebenzisa ubuchule bayo. Njengomboneleli okhethekileyo we-microwave engasebenziyoizinto ezisetyenziswayo, Ipotifoliyo yemveliso yeConcept Microwave ixhasa iziseko eziqinileyo ezifunwa ziinethiwekhi zanamhlanje ze-3G, 4G, kunye ne-5G. Ngokubonelela ngezinto ezisemgangathweni ophezulu nezithembekileyo ezenzelwe uzinzo kwiimeko ezimandundu zokusingqongileyo kunye nobushushu, inkampani inegalelo ekwakheni iinethiwekhi ezingenazingcingo ezizinzileyo, ezisebenzayo, nezihambelana ngokupheleleyo nezakha umqolo wonxibelelwano lwehlabathi.
