Kugwirizanitsa Chingwe Kungagwiritse Ntchito Pulogalamu Yanu Pang'ono Pake Kulimbana Kwake
Chida cha 802.11n cha Wi-Fi chimagwirizanitsa mpaka 300 Mbps yavotere (zongopeka) bandwidth pansi pazifukwa zabwino. Tsoka ilo, chiyankhulo cha 802.11n nthawi zina chimagwira ntchito mofulumira kwambiri monga 150 Mbps ndi pansipa.
Kuti mutumikire 802.11n kuti muthamangitse paulendo wake wapamwamba, maulendo opanda mauthenga opanda mauthenga opanda waya ndi othandizira makanema ayenera kugwirizanitsidwa ndi kuthamanga mu zomwe zimatchedwa channel bonding mode.
802.11n ndi Channel Bonding
Mu 802.11n, kugwirizanitsa kumagwiritsa ntchito njira ziwiri zoyandikana ndi Wi-Fi panthawi imodzimodziyo kupititsa chiwongolero cha makina opanda waya poyerekeza ndi 802.11b / g. Mtengo wa 802.11n umatanthawuza 300 Mbps chiwerengero cha bandwidth chikupezeka pogwiritsira ntchito kanjira. Popanda izo, pafupifupi 50 peresenti ya bandwidth iyi imatayika (makamaka pang'ono chifukwa cha zokhudzana ndi malamulo a pamwamba), ndipo pazochitikazi, zipangizo 802.11n zidzanena kuti zogwirizana ndi 130-150 Mbps ziwerengedwe.
Kulumikizana kwachitukuko kumawonjezera chiopsezo cha kusokoneza ma intaneti omwe ali pafupi ndi Wi-Fi chifukwa cha kuchuluka kwa magetsi ndi mphamvu zomwe zimadya.
Kukhazikitsa Bonding Channel 802.11n
Zolemba 802.11n kawirikawiri sizikuthandizani kugwirizanitsa makina mwachindunji koma mmalo mwake, muthamangire njira yachikhalidwe yokha yosungira kuti pangakhale chiopsezo chotsika. Onse ogula ndi opanda waya A N makasitomala ayenera kukonzekera kuti ayendetse mu njira yogwirizanitsa pamodzi kuti akwaniritse ntchito iliyonse yopindula.
Mayendedwe opangidwira kanjira ogwirizana amasiyana malinga ndi mankhwala. Pulogalamuyi nthawi zina imatanthawuza njira imodzi yokhayo yomwe imachitika 20 MHz (20 MHz kukhala width ya Wi-Fi channel) komanso njira yogwirizana monga 40 MHz ntchito.
Zolephera za 802.11n Channel Bonding
Zida 802.11n zimatha kulephera kugwira ntchito pamtunda (300 Mbps) pazifukwa izi:
- Zida 802.11n sizikhoza kuthandizira kulumikizana. Mwachitsanzo, mawonekedwe opanda waya awa ndi boma lolamulidwa m'mayiko ena ngati UK
- Ngati makina 802.11n akuphatikiza makasitomala 802.11b / g, makina onse ogwira ntchito angasokonezedwe, malingana ndi mphamvu za router. Chifukwa makasitomala 802.11b / g sagwirizana ndi makanema, izi ziyenera kukhazikitsidwa bwino ndi mawonekedwe osakanikirana a Wireless N router kuti achepetse zotsatira za ntchito.
- Kusakanikirana kwa magetsi ena 802.11n pafupi kumatha kuteteza mawotchi opanda waya N kupititsa chingwe chogwirizana. Ndipotu, ma routers ena opanda waya akubwerera kumalo osakanikirana amodzi pamene akuwona kusokoneza kwapakati pazitsulo
- Ngakhale kugwirizana kumatha kuthamanga pa 300 Mbps, sizikutanthauza kuti zipangizo zingathe kukopera ndi kukweza deta mofulumira. Chifukwa chimodzi chachikulu cha izi ndi chakuti kusindikiza kwa ISP sikulola kuti msinkhu wapamwamba (monga ngati mukulipirira 100 Mbps)
Monga momwe zimakhalira ndi mawebusaiti ena, mapulogalamu omwe akuyenda pa intaneti 802.11n nthawi zambiri amatha kuona zochepa zenizeni kusiyana ndi zomwe zimawerengedwa kuti zimagwiritsidwa ntchito ndi malo ogwirizana. Ma 300 Mbps adawerengera 802.11n kugwirizanitsa kawirikawiri kumabweretsa 200 Mbps kapena zosachepera zosinthidwa.
Single Band vs. Dual Band 802.11n
Mitundu ina yopanda foni ya Wireless N (yotchedwa N600) imalengeza thandizo la 600 Mbps mofulumira. Mawotchiwa sapereka 600 Mbps ya bandwidth pa mgwirizano umodzi koma m'malo mwake 300 Mbps njira yolumikiza pa 2.4 GHz ndi 5 GHz magulu ma frequency.
