zinthu pang'onopang'ono pa intaneti
Kuthamanga kwa intaneti kumadalira pazinthu zambiri, zomwe ndizofunikira kwambiri ndi izi: Mtundu wa nthaka Imayang'anira kuthamanga kwa intaneti komwe wogwiritsa ntchitoyo amapeza kuchokera kwa omwe amagwiritsa ntchito intaneti,
Tiyerekeze kuti mukulembetsa pa liwiro la 30 Mbps, mtundu wa mzerewo uyenera kukhala wabwino kwambiri kuti izi zitheke
Zina mwazinthu zomwe zimawongolera mtundu wa mzere:
Chiwerengero cha Signal-to-Noise SNR
Chiwerengero cha phokoso ndi phokoso ndiyofunika kuyeza ma decibel (dB) ndikufotokozera ubale womwe ulipo pakati pamlingo wamagetsi wama data womwe umadutsa pa telefoni motsutsana ndi phokoso lomwe likukhudza mzerewo. Ngakhale zingwe zangwiro zimayamwa phokoso lina.
Izi ndi zodabwitsa 'Zolembandiko kusokoneza kwamagetsi komwe kumachitika chifukwa cha:
Zingwe zina pafupi ndi foni monga zingwe zamagetsi Ndi chingwe cholumikizira chomwe chimatumiza chiwonetsero cha TV.
- otsogolera osauka.
Motors ndi magetsi osinthira pafupi ndi chingwe.
Ma towers awayilesi, omwe amatanthauza nsanja zomwe zimatumiza zikwangwani zamagetsi pama frequency radio, monga nsanja zoyankhulirana, intaneti, komanso mawayilesi.
Kutalika kwa mtengo wa decibel, kumakulirakulira mtengo wa SNR Mukakhala bwino mzere wanu, chizindikirocho chimakhala champhamvu kuposa phokoso.
- Ngati mtengo wake ndi 29 dB kapena kupitilira apo, zikutanthauza kuti phokosolo ndilofooka kwambiri ndipo izi zikuwonetsa mzere wabwino kwambiri.
- Ngati mtengo uli pakati pa 20-28 dB, izi ndi zabwino kwambiri, zikutanthauza kuti mzerewo ndi wabwino ndipo palibe zovuta zomwe zimakhudza kuthamanga.
- Ngati mtengo uli pakati pa 11-20 dB izi ndizovomerezeka.
- Ngati mtengo wake ndi wochepera 11 dB, izi ndi zoyipa ndipo pamakhala phokoso lalikulu pachizindikiro, chomwe chimakhudza kuthamanga kwa intaneti.
Mzere Attenuation
Chingwe chilichonse Padziko Lapansi chimadwala.
Ndi muyeso wofotokozera kutayika kwamphamvu yamagetsi mukamadutsa chingwe. Mtengo uwu umadalira mtunda pakati pa wosuta ndi kusinthana kwa matelefoni, komanso mtundu wa chingwe chamkuwa chomwecho. Mzere Attenuation Izi zikutanthauza kutayika kwakukulu pamphamvu ya chizindikiritso chodutsa pamzere, chomwe chimapangitsa kuti anthu azitha kugwiritsa ntchito intaneti mwachangu chifukwa chotsika kwambiri kuposa momwe amachitira ndi omwe amakupatsani mwayi wogwiritsa ntchito intaneti.
Ndipo mosemphanitsa, kuchepa kwa mtunda pakati pa inu ndi kusinthana kwamafoni, kumachepetsa mtengo wa Mzere Attenuation Izi zikutanthauza kuti mupeza intaneti mwachangu.
Ngati mtengo uli 20 dB kapena ochepera, ndizabwino kwambiri.
Ngati mtengo uli pakati pa 20-30 dB, ndizabwino kwambiri.
- Ngati mtengo uli pakati pa 30-40 dB ndizabwino kwambiri.
Ngati mtengo uli pakati pa 40-50 dB zili bwino.
Ngati mtengo uli wokulirapo kuposa 50 dB izi ndizoyipa ndipo mupeza intaneti yapakatikati komanso kuthamanga kosakwanira.
Kuthamanga kwa intaneti kumakhudzidwa mwachindunji ndi Mzere Attenuation Tsoka ilo, ngati mtunda wapakati pa inu ndi kusinthanitsa matelefoni uli patali kwambiri, palibe chomwe mungachite pothana ndi vutoli kupatula kulumikizana ndi omwe akukhala mundawo ndi kuwauza kuti mukufuna kupita kumalo osinthira mafoni apafupi.
Kodi ukadaulo wa ADSL ndi chiyani ndipo umagwira bwanji?
Pali malingaliro ena omwe mungapange kuti muwongolere chiwonetsero chazizindikiro ndi phokoso (SNR)
• Gulani rauta yabwino kwambiri Ikhoza kuthana ndi chiŵerengero cha SNR otsika.
• Gwiritsani ntchito chiboda Ubwino wabwino kusiyanitsa njira yapa telefoni kuchokera pa intaneti mu mzere wamkuwa.
Chifukwa chiyani timagwiritsa ntchito ziboda?
• Sinthani zingwe zolumikizira ndikugwiritsa ntchito zingwe zatsopano komanso zabwino kwambiri, chifukwa zingwe zosavomerezeka zimatha kusokoneza mzere.
Fotokozani momwe mungachotsere ntchito yochepetsa intaneti
Ndipo muli ndi thanzi labwino komanso chitetezo cha otsatira athu okondedwa
