Amakholi asetshenziselwa ukukhulumisana kwamaselula ayebikezelwa ukuhamba ngokushesha ekungabikho khona, kanye nokubikezela ukulahlekelwa umsakazo nokufika kwethelevishini. Kodwa amafoni asekhaya awazange anyathele noma kuphi, aguqule kancane kancane. Ifoni evamile yafakwa esikhundleni se-radiotelephone.
Ungakhetha kanjani i-radiotelephone efanele?
Ukuzikhethela i-radiotelephone kuncike ekutheni izici zayo zobuchwepheshe, kodwa futhi endaweni okuzofakwa kuzo, ihhovisi noma ikhaya elithengiwe. Yikuphi ifoni okufanele uyikhethe endlini, uhlobo luni lwehhovisi?
Amafoni ehhovisi akufanele nje abe yinto ehlelekile, umsebenzi wabo oyinhloko kufanele ukhululeke.
Ukutholwa kwe-tube
Umsebenzi weHhovisi udinga ukukhishwa kwamanye amacala ngesikhathi esisodwa, ngakho izingxoxo efonini zivame ukuhlanganiswa nokufuna amaphepha adingekayo, ukudweba umbiko, njll. Ngakho-ke, ihendisethi ye-handset kumele ibe yinto elula, ekhululekile ngendlela efanele ukuze ikwazi ukugcinwa kalula eduze nendlebe ngehlombe.
Uhlu lokuxhumana
Enye ipharamitha ebalulekile ye-radiotelephone yehhovisi yilona uhla lokuxhumana. Uma inkampani inehhovisi elilodwa, kuyoba yi-40 MHz ngokwanele. Le mvamisa izohlinzeka ngokuxhumana kumgama wamamitha angu-300-400 ukusuka kwesisekelo. Uma inkampani itholakala emahhovisi amaningana, noma, ikakhulukazi, amahhovisi asemaphethelweni ahlukene emgodini, kungcono ukuthenga i-radiotelephone ngezinga eliphakeme lemvamisa. Kulezo zinkampani lapho abasebenzi kufanele bahambe khona nge-tube yocingo esebenzayo noma baphume ngaphandle kwehhovisi ku-garaji, ukhetho olungcono luzoba yi-900 MHz. I-radiotelephone enjalo isebenza kude kufikela ku-1.5 km ukusuka kwesisekelo.
Inombolo yamatayipi
Kunamamodeli angase asekele umsebenzi weyodwa, kodwa amashubhu amaningana. Ehhovisi, imodeli enjalo ye-radiotelephone ingaba lula kakhulu.
Ibhetri
Amandla ayo ancike esikhathini lapho amashubhu angenza ngaphandle kokuvuselela. Ehhovisi, ukugcina ibhethri akulungile.
Ungakhetha kanjani ifoni yasekhaya?
Ukukhethwa kwefoni yocingo yisici esinqumayo ukuhamba kwezokuxhumana. Uma ifoni ikhethiwe efulethini elincane, imvamisa ingama-40 MHz. Indlu enkulu yezwe elingaphansi phansi imvamisa kufanele ibe ngaphezulu. Ukusebenza okuphezulu kwe-900 MHz yendlu kanye nefulethi kuyoba okungenasisekelo.
Ama-mistress amaningi asetshenziselwa ukukhuluma efonini ngaphandle kokuphazamisa inqubo yokulungiselela isidlo sakusihlwa. Ngakho-ke i-radiotrub kumele ibe lula futhi ikhululekile.
