Ezindaweni ezivalekile njengemihubhe nezindawo ezingaphansi komhlaba, izimpawu ezingenantambo zivame ukuvinjelwa kakhulu, okuholela ekutheni amadivayisi okuxhumana afana namafoni eselula namadivayisi enethiwekhi engenantambo angasebenzi kahle. Ukuze kuxazululwe le nkinga, onjiniyela bathuthukise amadivayisi ahlukahlukene okukhulisa izimpawu. Lawa madivayisi angathola izimpawu ezingenantambo ezibuthakathaka futhi azikhulise, okwenza amadivayisi angenantambo asebenze ngokujwayelekile endaweni evalekile. Ngezansi, sizokwethula amanye amadivayisi avamile okukhulisa izimpawu asetshenziswa emihubheni nasezindlini ezingaphansi komhlaba.
1. Uhlelo lwe-Antenna Olusatshalaliswe (i-DAS)
Uhlelo lwe-antenna olusakazwayo luwuhlelo lokukhulisa isignali olusetshenziswa kakhulu, olwethula izignali zangaphandle ezingenantambo endaweni yangaphakathi ngokufaka izi-antenna eziningi ngaphakathi kwemigudu kanye nezindawo ezingaphansi komhlaba, bese lukhulisa futhi lusakaze izignali ezingenantambo ngama-antenna asatshalaliswe. Uhlelo lwe-DAS lungasekela opharetha abaningi kanye nama-frequency band amaningi, futhi lufanelekela izinhlelo ezahlukene zokuxhumana ezingenantambo, okuhlanganisa i-2G, 3G, 4G, kanye ne-5G.
2. Isikhulisi sesiginali sohlobo lwe-Gain
I-amplifier yesignali yohlobo lwe-gain ifinyelela ukumbozwa kwesignali ngokwamukela nokukhulisa amasignali angenantambo abuthakathaka, bese iwathumela futhi. Lolu hlobo lwedivayisi luvame ukuba ne-antenna yangaphandle (amasignali okwamukela), i-amplifier yesignali, kanye ne-antenna yangaphakathi (amasignali okudlulisa). I-amplifier yesignali yohlobo lwe-gain ifanelekela amakamelo amancane angaphansi komhlaba kanye nemigudu.
3. Uhlelo lokuphindaphinda lwe-fiber optic
Uhlelo lokuvuselelwa kwe-fibre optic luyisisombululo sokukhulisa isignali esisezingeni eliphezulu esiguqula amasignali angenantambo abe amasignali optical, abese edluliselwa ngaphansi komhlaba noma ngaphakathi kwemigudu ngokusebenzisa ama-fiber optical, bese eguqulwa abe amasignali angenantambo ngokusebenzisa ama-fiber optic receiver. Inzuzo yalolu hlelo ukuthi lunokulahlekelwa okuncane kokudluliselwa kwesignali futhi lungafinyelela ukudluliselwa kanye nokumbozwa kwesignali ebanga elide.
4. Iseli Elincane
Isiteshi esincane sesisekelo uhlobo olusha lwedivayisi yokukhulisa isignali enekhono layo lokuxhumana okungenantambo futhi engakwazi ukuxhumana ngqo namafoni aphathwayo kanye namanye amadivayisi angenantambo. Iziteshi ezincane zesisekelo zivame ukufakwa ophahleni lwemihubhe kanye nezindawo ezingaphansi komhlaba, okuhlinzeka ngokumbozwa kwesignali okungenantambo okuzinzile.
Lokhu okungenhla kungenye yamadivayisi avamile okukhulisa isignali asetshenziswa emihubheni nasezindlini ezingaphansi komhlaba. Lapho ukhetha idivayisi, kubalulekile ukucabangela izici ezifana nezidingo zangempela zokumbozwa, isabelomali, kanye nokuhambisana kwedivayisi ukuze ukhethe idivayisi efaneleka kakhulu kuwe.
