Emhlabeni wezokuxhumana, izakhiwo eziphakeme ezibonisa indawo zingaphezu nje kwengxenye yendawo. Le mibhoshongo yezokuxhumana, ikakhulukazi imibhoshongo ye-monopole, idlala indima ebalulekile ekuqinisekiseni ukuthi amanethiwekhi ethu okuxhumana asebenza ngaphandle komthungo.
Okokuqala, ake siqonde ukuthi uyini umbhoshongo we-monopole. Umbhoshongo we-monopole, owaziwa nangokuthi i-telecom monopole, uwumbhoshongo owodwa, oqondile ovame ukusetshenziselwa ukusekela izimpondo zokuxhumana ngocingo. Ngokungafani nemibhoshongo ye-lattice yendabuko, ama-monopoles alula futhi azacile, okuwenza abe yinketho ethandwayo ezindaweni zasemadolobheni nasezindaweni ezingaphansi kwedolobha lapho isikhala silinganiselwe. Idizayini yabo ivumela ukufakwa kwezimpondo eziningi ezindaweni eziphakeme ezihlukahlukene, okubenza baguquguquke futhi basebenze kahle ekudluliseni nasekutholeni amasignali.
Enye yezingxenye ezibalulekile ezifakwe emibhoshongweni ye-monopole i-antenna yokuxhumana ngocingo. Lawa ma-antenna afika ngezinhlobo ezahlukahlukene, futhi enye yezinhlobo ezivame ukusetshenziswa ngemibhoshongo ye-monopole i-monopole antenna. I-monopole antenna, njengoba negama liphakamisa, iklanyelwe ukusebenza ngokubambisana nemibhoshongo ye-monopole. Iwuthi olume mpo olusetshenziswa kabanzi ukusakaza kanye nezinjongo zokuxhumana. Ubulula nokusebenza kwayo kuyenza ikhetheke kakhulu ezinhlelweni zokuxhumana ngocingo.
Idizayini ye-antenna ye-monopole ivumela imisebe ye-omnidirectional, okusho ukuthi ingadlulisela futhi yamukele amasignali kuzo zonke izinhlangothi, iyenze ifanelekele ukukhonza indawo ebanzi. Lokhu kuyenza ibe inketho ekahle yokuxhumana namaselula, ukusakaza, nezinye izinhlelo zokusebenza ezingenantambo. Ukwengeza, usayizi ohlangene we-antenna ye-monopole kanye nokufaka kalula kwayo kuyenza ibe yisixazululo esisebenzayo sokugxumeka emibhoshongweni ye-monopole, ikakhulukazi ezindaweni lapho isikhala siphezulu kakhulu.
Uma kukhulunywa ngengqalasizinda yezokuxhumana, indima yemibhoshongo ye-monopole nama-antenna angeke yeqiswe. Lezi zakhiwo zakha umgogodla wamanethiwekhi ethu okuxhumana, okusenza sikwazi ukuhlala sixhumekile emhlabeni wethu owandayo wedijithali. Kungakhathaliseki ukuthi kuqondisa izingcingo zamaselula, uxhumano lwe-inthanethi, noma ukusakaza ulwazi olubalulekile, imibhoshongo ye-monopole nezimpondo zibalulekile ekusigcineni sixhumekile.
Sengiphetha, imibhoshongo ye-monopole nama-antenna ayizingxenye ezibalulekile zamanethiwekhi ezokuxhumana. Idizayini yabo ephumelelayo, ukuguquguquka, kanye nekhono lokusekela izinhlobo ezahlukene zezimpondo, okuhlanganisa i-monopole antenna, kubenza babaluleke kakhulu emhlabeni wezokuxhumana. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, indima yemibhoshongo ye-monopole kanye nezimpondo zizoba bucayi kakhulu ekuhlangabezaneni nezidingo ezikhulayo zokuxhumana okungenamthungo nokuthembekile.
Ezweni elihlala livela lezokuxhumana, imibhoshongo ye-monopole kanye nezimpondo zimi zinde, ngokwezwi nezwi, njengezinsika zokuxhuma, eziqinisekisa ukuthi sihlala sixhumekile.
