Izikhulisi zesiginali yeselulangokwazo azinawo umonakalo othe ngqo. Zizixhobo ze-elektroniki ezenzelwe ukuphucula iimpawu zeselula, ezihlala ziquka i-antenna yangaphandle, i-amplifier, kunye ne-antenna yangaphakathi eqhagamshelwe ngeentambo. Injongo yezi zixhobo kukubamba iimpawu ezibuthathaka kunye nokuzikhulisa ukuze zibonelele ngomgangatho ongcono wonxibelelwano lweselula kunye nokugubungela iimpawu.
Nangona kunjalo, kukho amanqaku aliqela ekufuneka uwaqwalasele xa usebenzisa ii-amplifier zesignali zeselula:
Ukusemthethweni: Xa usebenzisaisandisi-lizwi seselula, kufuneka uqinisekise ukuba kusemthethweni kwaye kuyahambelana nemigaqo yasekuhlaleni. Iindawo ezithile zinokuba nemiqathango okanye izithintelo ekusebenziseni ii-amplifier kwiibhendi ezithile zefrikhwensi, njengoko zinokuphazamisana nokusebenza okuqhelekileyo kwezinye izixhobo ezingenazingcingo okanye izikhululo zesiseko.
Ukufakelwa nokusetyenziswa okungafanelekanga: Ukufakelwa okungafanelekanga okanye ukusetyenziswa okungafanelekanga kwe-amplifier yesignali kunokukhokelela ekuphazamisekeni nakwimiba. Umzekelo, ukuba ubude bentambo phakathi kwee-antenna zangaphakathi nezangaphandle bude kakhulu okanye ukuba intambo ayilunganga, inokubangela ukulahleka kwesignali okanye iingxaki zempendulo.
Imitha ye-electromagnetic:Izikhulisi zesiginali yeselulazifuna umbane, oko kuthetha ukuba zivelisa inqanaba elithile lemitha ye-electromagnetic. Nangona kunjalo, xa kuthelekiswa neefowuni eziphathwayo okanye ezinye izixhobo zonxibelelwano ezingenazingcingo, inqanaba lemitha ye-amplifiers lihlala liphantsi kuba zihlala zenzelwe ukusetyenziswa ngaphakathi endaweni yokuba zisondelelene nomzimba womntu. Nangona kunjalo, ukuba unomdla kwimitha ye-electromagnetic okanye uneengxaki zempilo, ungathatha amanyathelo afanelekileyo okuthabatha amanyathelo afanelekileyo njengokuhlala kude ne-amplifier okanye ukhethe izixhobo ezinemitha ye-electromagnetic ephantsi.
Ukuphazamiseka kwesignali: Ngelixa injongoizikhulisi zesignali yeselulakukubonelela ngemiqondiso eqinileyo, ukufakelwa okanye ukusetyenziswa okungafanelekanga kunokungenisa ukuphazamiseka kwesignali. Umzekelo, ukuba i-amplifier ibamba kwaye ikhulisa iimpawu eziphazamisayo ezivela kwizixhobo ezikufutshane, oko kunokubangela ukwehla komgangatho wonxibelelwano okanye ukuphazamiseka.
Ngamafutshane, ii-amplifier zesignali zeselula ezifunyenwe ngokusemthethweni nezifakwe ngokufanelekileyo ngokubanzi azinawo umonakalo othe ngqo. Nangona kunjalo, kubalulekile ukuthobela imithetho yendawo, ukulandela iingcebiso kunye nezikhokelo zomenzi, kunye nokuqinisekisa ukufakwa nokusetyenziswa okufanelekileyo. Ukuba unemibuzo okanye iingxaki, kungcono ukubonisana neengcali okanye amagunya afanelekileyo ukuze ufumane iingcebiso kunye nesikhokelo esichanekileyo.
