I-eriyali yangaphandle 470-510MHz i-eriyali yesabhokhwe eguquguqukayo
Intshayelelo yeMveliso
I-eriyali ye-470-510MHz bhetyebhetye yi-eriyali yonxibelelwano engenazingcingo esebenza kakuhle.Isebenzisa isidibanisi sendoda ye-SMA ukuququzelela uqhagamshelo ngezixhobo ezahlukeneyo kwaye ifanelekile ukusetyenziswa kwiindawo ezingaphandle.Ukuphumelela kwemitha ye-eriyali kufikelela kuma-53%, okuthetha ukuba inokuguqula ngokufanelekileyo amandla ombane abe ngumbane osasazwayo kwaye inike ukuhanjiswa komqondiso okuzinzileyo.Ngexesha elifanayo, inzuzo yayo ephezulu idlula i-1 dBi kwaye inamandla okuphucula umqondiso, onokukwandisa uluhlu lonxibelelwano.
Le eriyali isetyenziswa ngokubanzi kwiimeko ezahlukeneyo, kubandakanya ukulinganisa ngemitha ngobuchule, isango, ukujongwa ngaphandle kwamacingo kunye nothungelwano lwemesh.Kwinkalo yokulinganisa i-smart metering, ingasetyenziselwa ukunxibelelana neemitha zombane ezikrelekrele, iimitha zamanzi kunye nezinye izixhobo ukufezekisa ukuqokelelwa kwedatha ekrelekrele kunye nokubeka iliso kude.Ngokubhekiselele kumasango, inokudibanisa kunye nezixhobo ezahlukeneyo zesango ukubonelela ngenkxaso yonxibelelwano olungenacingo oluzinzileyo.Kwizicelo zokucupha ezingenazingcingo, zingasetyenziselwa ukuhanjiswa komqondiso weekhamera zokucupha ividiyo kunye nezinye izixhobo zokuqinisekisa umgangatho wevidiyo kunye nokuzinza.Kwinethiwekhi ye-mesh, inokusetyenziswa njengendlela yokunxibelelana phakathi kwezixhobo ze-node ukuqonda utshintshiselwano lwedatha kunye nomsebenzi wokubambisana phakathi kwezixhobo.
I-eriyali inepateni egqwesileyo yothumelo lwe-omnidirectional, okuthetha ukuba isasaza imiqondiso ngokulinganayo kuwo onke amacala, ibonelela ngokhuseleko olubanzi.Oku kuyenza ibe yinto efanelekileyo kwizicelo ezifuna ukhuseleko kwiindawo ezinkulu, ezifana nezakhiwo ezinkulu, imimandla yasezidolophini, njl njl. Nokuba ingaphakathi okanye ngaphandle, le eriyali inokubonelela ngenkxaso yonxibelelwano olungenacingo oluzinzileyo nolusebenzayo.
