izici ze-intanethi ezihamba kancane

Ijubane le-Intanethi lincike ezintweni eziningi, ezibaluleke kakhulu kuzo yilezi: Ikhwalithi yomugqa womhlaba Ilawula isivinini se-Intanethi umsebenzisi asithola kumhlinzeki wesevisi ye-Intanethi,

Ake sithi ubhalisela isivinini sama-Mbps angama-30, ikhwalithi yomugqa kufanele ibe mihle kakhulu ukuze uthole leli jubane ngokugcwele

Phakathi kwezinto ezilawula ikhwalithi yomugqa:

Isiginali-to-Noise ratio SNR

Isilinganiso sesiginali-to-noise yinani elilinganiswe ngama-decibel (dB) futhi uchaze ubudlelwane obuphakathi kwezinga lamandla esiginali wedatha edlula kulayini wocingo uma kuqhathaniswa nomsindo othinta umugqa. Ngisho nezintambo ezifanele zithatha umsindo othile.

Lokhu kuyamangaza 'umsindo'ukuphazanyiswa kwamandla kagesi okubangelwa:

Ezinye izintambo eziseduze nolayini wocingo njenge izintambo ezinamandla amakhulu Nentambo ye-coaxial edlulisa isignali ye-TV.
- abaqhubi abampofu.
Ama-motor nama-transformer kagesi eduze kwekhebula.
Imibhoshongo yomsakazo, okusho leyo mibhoshongo edlulisa amasiginali kagesi ebangeni lemvamisa yomsakazo, njengemibhoshongo yezokuxhumana, i-Intanethi, kanye nokusakazwa komsindo.

Ukuphakama kwenani le-decibel, kukhula inani le-. I-SNR Uma ulayini wakho ungcono, isignali inamandla ngaphezu komsindo.
- Uma inani lingu-29 dB noma ngaphezulu, kusho ukuthi umsindo ubuthakathaka kakhulu futhi lokhu kukhombisa ikhwalithi ephezulu yomugqa.
- Uma inani liphakathi kuka-20-28 dB, lokhu kuhle kakhulu, kusho ukuthi ulayini muhle futhi azikho izinkinga ezithinta ijubane.
- Uma inani liphakathi kuka-11-20 dB lokhu kuyamukeleka.
- Uma inani lingaphansi kuka-11 dB, lokhu kubi futhi kunomsindo omkhulu kusiginali, othinta isivinini se-Intanethi.

 Ukuncishiswa komugqa

Yonke ikhebuli esemhlabeni ihlushwa ukuncipha.

Kuyindlela echaza ukulahleka kwamandla esignali lapho kudlula ikhebula. Leli nani lincike ebangeni eliphakathi komsebenzisi nokushintshaniswa kwefoni, kanye nekhwalithi yolayini wethusi uqobo. Ukuncishiswa komugqa Lokhu kusho ukulahleka okukhulu ngamandla esignali edlula kulayini, okwenza ukuthi ukungena okungaxhunyiwe ku-inthanethi kube kubi futhi ngaleyo ndlela kube yisivinini esiphansi kunesivumelwano nomhlinzeki wesevisi ye-Intanethi.
Futhi okuphambene nalokho, uma libanga lincane phakathi kwakho nokushintshana ngocingo, kwehla inani le- Ukuncishiswa komugqa Lokhu kusho ukuthi uzothola ukuxhumeka kwe-inthanethi okusheshayo.

Uma inani lingu-20 dB noma ngaphansi, lokho kupholile kakhulu.
Uma inani liphakathi kuka-20-30 dB, lokho kuhle kakhulu.
- Uma inani liphakathi kuka-30-40 dB lokho kuhle kakhulu.
Uma inani liphakathi kuka-40-50 dB lokho kulungile.
Uma inani likhulu kuno-50 dB lokhu kubi futhi uzothola ukufinyelela kwe-inthanethi okungena ngezikhathi ezithile nesivinini esibi.

Ijubane le-Intanethi lithinteka ngqo yi Ukuncishiswa komugqa Ngeshwa, uma ngabe ibanga phakathi kwakho nokushintshisana ngocingo likude kakhulu, akukho lutho ongalwenza ngale nkinga ehamba kancane ngaphandle kokuxhumana nabasebenza ocingweni lwasendlini ubatshele ukuthi ufuna ukuya enhlanganweni yezingcingo eseduzane nawe.

Buyini ubuchwepheshe be-ADSL futhi busebenza kanjani?

Kunezincomo ezithile ongazenza ukuthuthukisa isilinganiso se-signal-to-noise (SNR)

• Thenga umzila omuhle kakhulu Ingaphatha isilinganiso se- I-SNR phansi.
• Sebenzisa I-Splitter Ikhwalithi enhle yokuhlukanisa ishaneli yocingo nesiteshi se-Intanethi kulayini wethusi.

Kungani sisebenzisa idabula?
• Shintsha izintambo zokuxhuma bese usebenzisa izintambo ezintsha zekhwalithi ezisezingeni eliphakeme, njengoba izintambo zekhwalithi ephansi zingaphazamisa ulayini.

Chaza ukuthi ungayisusa kanjani insizakalo ye-intanethi yasekhaya ehamba kancane

Incazelo yokumisa Windows 10 buyekeza futhi uxazulule inkinga yesevisi ye-Intanethi ehamba kancane
