Uma indlu yethu ingenayo isignali yomakhalekhukhwini, kufanele siyixazulule kanjani?
Okokuqala, ake sibhekeukukhishwa kwesignaliezindaweni zokuhlala. Ngenxa yokukhosela kwezakhiwo kanye nokuphazamiseka kwamagagasi kagesi, isignali yocingo lweselula izoba buthakathaka noma ingakwazi ukumbozwa. Kubahlali abahlala e-Tower block, le nkinga igqame kakhulu, ngoba i-Tower block ivinjwa kalula yizakhiwo ezizungezile, izihlahla nezinye izinto. Ngakho-ke, ukudluliswa kwezimpawu ngaphakathi kwezakhamuzi kuye kwaba nzima kakhulu.
Ukuxazulula le nkinga, abantu abaningi bakhetha ukwenza kanjalofaka izikhulisamsindo zesignali yeselula. Lolu wucingo oluklanyelwe ukuthuthukisa isignali yeselula. Inganikeza ukumbozwa kwamasignali okunamandla, iqinisekise ukuthi singasebenzisa amafoni ethu ngokuzinza ngaphakathi naseduze kwamakhaya ethu.
Kunezinzuzo eziningi zokufaka isikhulisi sesignali yeselula. Okokuqala, ingathuthukisa ikhwalithi yamakholi. Ama-amplifiers esignali angaqeda ukuncishiswa kwesignali nokuphazamiseka, enze izingcingo zicace futhi zizinze. Lokhu kubaluleke kakhulu ekuxhumaneni kwebhizinisi, izingcingo zomndeni nabangane, kanye nezimo eziphuthumayo.
Okwesibili, isikhulisi sesiginali yeselula singathuthukisa isivinini sokudluliswa kwedatha. Sivamise ukusebenzisa omakhalekhukhwini ukuze sihlole i-inthanethi, njengokuphequlula amakhasi ewebhu, ukubuka amavidiyo, nokulanda amafayela. Nokho, uma isignali ingeyinhle, isivinini senethiwekhi singahamba kancane noma singazinzi. Ukufaka isikhulisi sesignali kungaxazulula le nkinga ngempumelelo, kusheshise isivinini sokudluliswa kwedatha, futhi kuthuthukise ulwazi lomsebenzisi.
Ngaphezu kwalokho, i-isandisi sesignaliinganweba futhi iukusabalala kwesignaliububanzi. Ezinye izindawo zokuhlala zitholakala ezindaweni eziyinkimbinkimbi, njengezindawo zezintaba, kude namadolobha, noma izakhiwo eziphakeme. Kulezi zindawo, isignali yeselula ivamise ukuvinjwa, okuholela esignali ebuthaka noma ukungabikho nhlobo uxhumano. Ukufaka isikhulisi sesignali kungaxazulula le nkinga, kuvumela isignali ukuthi ivale wonke amagumbi endlu, kuqinisekiswe ukuthi singasebenzisa amafoni ethu ngokukhululekile noma yikuphi.
Ukufingqa, ukufaka ama-amplifiers amasignali eselula kuyindlela ephumelelayo nevamile yokuxazulula inkinga yokungatholakali kwesignali okwanele ezakhiweni zokuhlala. Ayikwazi ukunikeza amasignali azinzile futhi anamandla kuphela, ithuthukise ikhwalithi yekholi kanye nesivinini sokudlulisa idatha, kodwa futhi yandise impilo yebhethri yamaselula futhi yehlise imisebe. Ngakho-ke, uma uhlangabezana nenkinga yokungabiki kahle kwesignali endlini, ungase ucabange ukufaka i-aIsikhulisi sesignali yeselulaukuyixazulula. Lokhu kuzokulethela impilo elula kakhudlwana kanye nolwazi olumnandi lomakhalekhukhwini.
