Kwangaxeshanye, abaqhubi banokulungisa ngokulula ulwakhiwo kunye noseto lweeparameter zezikhululo zesiseko ngokweemeko zokwenyani zegaraji ukuze bafumane ukugutyungelwa okungcono. Nangona kunjalo, ngenxa yeendleko eziphezulu zabaqhubi zokwakha izikhululo zesiseko, abathengi okwangoku kufuneka bathwale iindleko ezifanelekileyo zabaqhubi ukwakha izikhululo zesiseko. Iindleko zezikhululo zesiseko ezibonelelwa ngabaqhubi ziya kubiza kakhulu.
3. Isisombululo 2: Inkqubo ye-antenna esasazekileyo
Inkqubo ye-antenna esasazekileyo sisisombululo apho ii-antenna zisasazeke kuyo yonke igaraji. Ngokunciphisa umgama wokudluliselwa kwesignali kunye nokunciphisa ukuncitshiswa, inkqubo ibonelela ngokugubungela isignali ngokulinganayo ngaphakathi kwigaraji. Ukongeza, inkqubo ye-antenna esasazekileyo inokuqhagamshelwa ngaphandle komthungo kwinethiwekhi yonxibelelwano yeselula ekhoyo ukuqinisekisa ukuba abanini beemoto banokonwabela iinkonzo zonxibelelwano ezisemgangathweni ophezulu kwigaraji.
4. Isisombululo 3:Isiphindaphindi sefayibha ye-opticalinkqubo yokwandisa isignali
Kwiigaraji ezinkulu ezingaphantsi komhlaba, ungacinga ngokusebenzisaiziphindaphindi ze-fiber opticukuphucula umgangatho wesiginali. Esi sixhobo sinokuyiphucula ngempumelelo imeko-bume yonxibelelwano egaraji ngokufumana iziginali zangaphandle kunye nokuzikhulisa ngaphambi kokuba zithunyelwe ngaphakathi egaraji. Kwangaxeshanye, iziphindaphindi ze-fiber optic kulula ukuzifaka kwaye zingabizi kakhulu, nto leyo ezenza zifaneleke kubasebenzisi abanebhajethi encinci.
5. Isisombululo 4: Lungiselela imeko-bume yangaphakathi yegaraji
Ukongeza kwiindlela zobugcisa, umgangatho wesiginali ungaphuculwa ngokwenza ngcono imeko-bume yangaphakathi yegaraji. Umzekelo, ukunciphisa ukusetyenziswa kwezakhiwo zesinyithi kwigaraji, ukuhlela ngokunengqiqo iindawo zokupaka iimoto, kunye nokugcina ukujikeleza komoya kwigaraji konke oku kunokunceda ukunciphisa ukuphazamiseka kwesiginali kunye nokuphucula ukusebenza kakuhle kokusasazwa kwesiginali.
6. Isisombululo esipheleleyo: thabatha amanyathelo amaninzi ngaxeshanye
Kwizicelo ezisebenzayo, kudla ngokufuneka ukuba kusetyenziswe indibaniselwano yezisombululo ezininzi ukuphucula umgangatho wesignali ngokusekelwe kwimeko yokwenyani kunye neemfuno zegaraji.
