Kodi Ndikutenga Nthawi Yanji?
Bandwidth imagwiritsidwa ntchito mofanana ndi kugwirizana kwagwirizanitsidwe, ngakhale mwamtheradi sali chimodzimodzi. Bandwidth ndilo maulendo osiyanasiyana omwe deta imafalitsidwa. Mfundo zomwezo zimagwiritsidwa ntchito pa kufalitsa kwa wailesi, TV ndi deta. Njira yaikulu ya bandwidth imatanthawuza kuti deta zambiri zimafalitsidwa panthawi imodzi, ndipo motero zimathamanga kwambiri. Ngakhale kuti tidzakhala tikugwiritsa ntchito mau awiriwa pano, ndithudi bandwidth sikulumikizana mwamsanga, ngakhale kuti amagwiritsidwa ntchito mofanana ndi ogwiritsa ntchito pa intaneti ambiri.
Kuyeza Bandwidth
Bandwidth imayesedwa mu Hertz (Hz), kapena MegaHertz (MHz) chifukwa Hertz amawerengedwa mwa mamilioni. MHz imodzi ndi Hz miliyoni imodzi. Kuthamanga kwagwirizanowu (kumatchedwa kuchepa kwache) kumayesedwa mu Kilobits pamphindi (kbps). Ndichiyeso chabe cha zingwe zomwe zimapititsidwa mumphindi imodzi. Ndigwiritsa ntchito kbps kapena Mbps kuti ndiloze kuwiro lakuthamanga kuchokera tsopano mpaka pano chifukwa ndicho chomwe aliyense wothandizira amalankhula ponena za liwiro limene amapereka. Mbps imodzi ndi kbps chikwi chimodzi.
Mukhoza kukhala ndi lingaliro la kugwirizana kwanu kapena koipa kwanu kugwirizana mofulumira komanso ngati kuli koyenera kwa VoIP pakuchita mayeso ogwirizana pa intaneti. Werengani zambiri pa mayesero ogwirizana apa.
Bandwidth Cost
Kwa anthu ambiri pogwiritsa ntchito intaneti ngati njira yolankhulirana, bandwidth imakhala yofunikira kwambiri, chifukwa imabwereza. Kwa kulankhulana kwa mawu, zofunikira zogwiritsira ntchito zing'onoting'ono ndizofunikira kwambiri, popeza mawu ndi mtundu wa deta yomwe ndi yosavuta kuposa yowonjezera.
Izi zikutanthauza kuti kuwonjezereka kwakukulu, kulimbitsa ubwino wa mawu omwe mungapeze. Masiku ano, kugwirizana kwa broadband ndikulankhulidwa kwachisawawa komanso kutsika mtengo ndi wotchipa.
Broadband ndi mgwirizano wopanda malire (maola 24 pa tsiku ndi zonse zomwe mukufuna kuzigwiritsa ntchito) pa liwiro kwambiri kuposa la 56 kbps.
Ambiri amapereka maulendo okwana 512 kbps lero, omwe ali okwanira kulankhulana kwa VoIP. Izi ndizochitika m'mayiko otukuka ndi m'madera. Kwa malo ena, ena ogwiritsira ntchito akadali ochepa pazowonjezera kuthamanga pamtengo wapamwamba.
Common Bandwidths
Tiyeni tiwone mawonekedwe ena a bandwidth omwe amagwiritsidwa ntchito ndi zipangizo zamakono zolankhulana ndi matekinoloje.
| Technology | Kuthamanga | Gwiritsani ntchito VoIP |
| Kusindikiza (modem) | Mpaka 56 kbps | Osati woyenera |
| ISDN | Mpaka 128 kbps | Zokwanira, chifukwa chokhazikika ndi utumiki wodzipereka |
| ADSL | Mpaka Mbps zingapo | Imodzi mwa matekinoloje abwino a WAN , koma siyikuthandiza |
| Zida zamakina (monga WiFi, WiMax, GPRS, CDMA) | Mpaka Mbps zingapo | Zipangizo zina zamakono zili zoyenera pamene zina zimachepera ndi mtunda ndi khalidwe la chizindikiro. Ndi njira zothandizira ADSL. |
| LAN (mwachitsanzo Ethernet ) | Kufikira zikwi zambiri za Mbps (Gbps) | Zabwino, koma zochepa ku waya wautali zomwe zingakhale zochepa nthawi zambiri. |
| Chingwe | 1 mpaka 6 Mbps | Kuthamanga kwakukulu koma kumachepetsa kuyenda. Ndibwino kuti musasunthe. |
Bandwidth ndi Apps
Mapulogalamu a VoIP pafoni yanu imagwiritsira ntchito chiwongolero chosiyana. Izi zimachokera ku codecs zomwe amagwiritsira ntchito kuti adziwitse deta yopatsirana ndi zina zamaganizo. Skype, mwachitsanzo, ili pakati pa mapulogalamu a VoIP omwe amagwiritsa ntchito deta kapena chiwongosoledwe pamphindi pa miniti yolankhulirana, chifukwa zimapereka mawu a HD.
Tsono, ngakhale kuti ubwino uli bwino kwambiri, mufunika kuthamanga kwambiri ndipo mumagwiritsa ntchito megabytes. Izi ndi zabwino pa WiFi, koma muyenera kukumbukira izi pogwiritsa ntchito data yanu. Werengani zambiri pa mafoni a m'manja.
