Ibhodi ye-eriyali yesignali yefowuni yeselula umqondiso wesizathu esinamandla

Isandisi-lizwi seselfowuniUmqondiso we-eriyali yebhodi isizathu esomeleleyo: Ngokubhekiselele kuphawu, i-eriyali yepleyiti enkulu “yinkosi” njengobukho!Nokuba kukwiitonela, kwiintlango, okanye ezintabeni nakwezinye iindawo ezibonisa ukuhanjiswa kwemiqondiso kumgama omde, unokuyibona rhoqo.Kutheni i-eriyali yepleyiti enkulu yomelele kangaka?Zeziphi iimeko ezinokusetyenziswa kuzo?Masijonge ngezantsi.

I-Antenna ye-Omnidirectional VS i-Antenna ye-Directional

I-antenna yepleyiti enkulu eneneni yi-eriyali ye-antenna ephezulu kakhulu yokuzuza umkhombandlela:

I-eriyali inemitha eyohlukeneyo okanye izakhono zokufumana iindlela ezahlukeneyo esithubeni, okukuko ngqo kwe-eriyali.Ngokwendlela eyahluka-hlukeneyo, i-eriyali ineendidi ezimbini ze-omnidirectional kunye ne-directional.

I-eriyali ye-Omnidirectional:

I-eriyali ye-Omnidirectional, oko kukuthi, kwipateni ethe tye njenge-360 ° imitha yemitha efanayo, oko kukuthi, i-eriyali eqhelekileyo, kwipatheni ethe nkqo njengobubanzi obuthile bomqadi, ngokubanzi, okukhona kuncinci ububanzi belobe, kokukhona kusiba nkulu inzuzo.

I-eriyali yomkhomba-ndlela:

I-eriyali yomkhomba-ndlela, kwipateni ethe tye yoluhlu oluthile lwemitha ye-angular, oko kukuthi, ulwalathiso oluqhelekileyo, kwipatheni ethe nkqo yobubanzi obuthile bomqadi, ngokufanayoi-eriyali ye-omnidirectional, incinci ububanzi belobe, inkulu inzuzo.I-eriyali eyalathayo isetyenziswa ngokubanzi kwinkqubo yonxibelelwano kumgama omde wonxibelelwano, indawo encinci yokugubungela, ingxinano enkulu ekujoliswe kuyo kunye nokusetyenziswa kwamaza amaninzi.

Umgaqo wokusebenza

I-antenna ye-Omnidirectional iya kuthumela imiqondiso kuwo onke amacala, omabini angaphambili nangasemva angafumana umqondiso, i-antenna eyalathayo ifana nesitya sokubonisa umphezulu emva kwemaski ye-antenna, umqondiso unokudluliselwa kuphela ngaphambili, umqondiso udutyulwe ngasemva. ivalwe sisibonisi kwaye ibonakaliswe ngaphambili, iqinisa amandla omqondiso ngaphambili.

Khetha ngokwendawo

Ukukhetha i-eriyali, ukuba izikhululo ezininzi zifuna ukwaneliseka kwaye ezi zikhululo zisasazwe kwiindlela ezahlukeneyo ze-AP,ii-eriyali ze-omnidirectionalkufuneka isetyenziswe.Njenge: izindlu, iivenkile, iindawo zokupaka.

Ukuba igxininiswe kwicala elinye, kuyacetyiswa ukuba usebenzise i-antenna eqondisayo;Njenge: itonela, iintlango, iindawo zemigodi, iipaseji.

UFakelo lokuQaphela

Umphambili we-eriyali yepleyiti enkulu ijonge kwicala lendawo ekude kwaye ifakwe phezulu kangangoko, kwaye umgama wokubonwa phakathi kwe-eriyali kunye nesiza ulungile kangangoko (ubonakala kwiliso lenyama, ukuphepha imiqobo embindini. ).

I-Lintratek ibonelela "isisombululo esisodwa sokugubungela umqondiso wefowuni yeselula" inkonzo, kubandakanywa ukuhambelana kwemveliso, ukuyila umgca, ukufakwa kunye nokugunyaziswa, kunye nenkonzo ekhethekileyo emva kokuthengisa, ukwenzela ukuba abathengi bakhululeke ngakumbi.
