Funso: Kodi 802.11 ndi chiyani? Ndondomeko iti yopanda waya iyenera kugwiritsa ntchito zipangizo zanga?
Yankho:
802.11 ndiyeso la miyambo yamakono yopangira mafano osakanikirana. Malamulo amenewa amatsimikiziridwa ndi IEEE (Institute of Electrical and Electronic Engineers), ndipo amawongolera momwe zipangizo zopanda waya zingapangidwire komanso momwe amalankhulirana.
Mudzawona 802.11 atatchulidwa pamene mukuyang'ana kugula chipangizo chopanda waya kapena chidutswa cha zipangizo zopanda waya. Mwachitsanzo, mukafufuza zomwe bukhuli likugula, mungawone kuti ena amalengeza ngati akulankhulana mosasunthika pa 802.11 n (kasi, Apple imagwiritsa ntchito zipangizo zamakono 802.11n pamakompyuta komanso zipangizo zamakono). Mzere wa 802.11 umatchulidwanso muzinena za mawonekedwe opanda waya; Mwachitsanzo, ngati mukufuna kulumikizana ndi malo opanda pakompyuta, mukhoza kuuzidwa kuti ndi intaneti 802.11 g .
Kodi makalata amatanthauzanji?
Kalata yotsatira "802.11" ikuwonetseratu kusinthika kwa muyezo woyambirira 802.11. Maluso opanda utsi kwa ogula / anthu onse apita patsogolo kuyambira 802.11a mpaka 802.11b mpaka 802.11g , posachedwapa, 802.11n . (Inde, malembo ena, "c" ndi "m," mwachitsanzo, amakhalanso ndi ma 802.11, koma ndi ofunika kwambiri kwa akatswiri a IT kapena magulu ena apadera a anthu.)
Popanda kufotokoza momveka bwino pakati pa 802.11a, b, g, ndi ma Intaneti, tikhoza kuwonetsa kuti 802.11 yatsopano imagwira ntchito yopanga mafayili, poyerekeza ndi kumasulira kwake,
- Dera la deta : kuthamanga kwapadera kwa deta (mwachitsanzo, momwe mwatsatanetsatane mauthenga angayende pa intaneti opanda waya)
- Mtunda : Mtunda wazitsulo zopanda zingwe zikhoza kufika kapena malo omwe mazenera opanda chivundi akuphimba (mwachitsanzo, kutalika kwake komwe mungakhale kuchokera kwa chitsimikizo chopanda waya ndikukhalabe ndi chingwe chodalirika)
802.11n (yomwe imatchedwanso "Wireless-N"), pokhala pulogalamu yatsopano yopanda waya, imapereka chiwerengero chapamwamba kwambiri cha deta lero ndi mabwalo abwino a zisudzo kuposa zamakono apamwamba. Ndipotu, maulendo 802.11n apita mofulumira mofulumira kuposa 802.11g; pa 300 kapena kuposa Mbps (megabits pamphindi) muzogwiritsiridwa ntchito kwenikweni, 802.11n ndi protocol yoyamba yopanda waya yopitilira movutitsa wired 100 Mbps Ethernet setups.
Zida zopanda zingwe zimapangidwanso kuti ziziyenda bwino kwambiri, kuti laputopu ikhale mamita 300 kutalika kwa chizindikiro chopanda mawonekedwe opanda waya ndikupitirizabe kuthamanga kwambiri. Mosiyana, ndi machitidwe akale, kuthamanga kwanu kwa deta ndi kugwirizana kumakhala kofooka pamene muli kutali ndi malo opanda malo opanda pakompyuta.
Ndiye bwanji osagwiritsira ntchito mankhwala opanda Wireless?
Zinatenga zaka zisanu ndi ziwiri kufikira pulojekiti ya 802.11n yomwe inatsimikiziridwa / yovomerezedwa ndi IEEE mu September wa 2009. Pa zaka zisanu ndi ziŵirizo pamene ntchitoyi ikugwiritsidwanso ntchito, zinthu zambiri zisanayambe "pre-n" ndi "draft" zotengera zitsulo zinayambitsidwa , koma nthawi zambiri sankagwira ntchito bwino ndi ma protocol ena opanda waya kapena zinthu zina zomwe zisanayambe 802.11n.
Kodi ndiyenera kugula makanema opanda makina / makina othandizira / kompyuta yamakono, ndi zina zotero?
Tsopano 802.11n wasindikizidwa - ndipo chifukwa magulu opanda mafakitale monga Wi-Fi Alliance akhala akukakamiza kugwirizana pakati pa 802.11n ndi 802.11 mankhwala - chiopsezo chogula zipangizo zomwe sitingathe kuyankhulana kapena ndi achikulire hardware yachepetsedwa kwambiri.
Kuwonjezeka kwa ntchito za 802.11n kumakhala koyenera kuyang'ana, koma kumbukirani zotsatila zotsatirazi posankha ngati zigwiritsenso ntchito 802.11g protocol kapena ndalama mu 802.11n tsopano :
- Ntchito yamagetsi idzakhala yaikulu pamene zipangizo zonse pamakina opanda waya akugwiritsa ntchito teknoloji ya 802.11n. Pa mbali ya flip, ngati chipangizo chakale chogwiritsira ntchito 802.11g kapena 802.11b chikugwirizana ndi router yanu 802.11n, kuthamanga kwa deta ndi deta ya zipangizo zonse pa intaneti kudzachepa. Njira imodzi yobweretsera nkhaniyi ndi intaneti yanu yopanda ulusi ndikupeza zomwe zimatchedwa awiri-band router kapena malo otha kupeza. Izi zidzalola zipangizo zakale kuti ziziyendetsa pafupipafupi (2.4 GHz) ndi zipangizo zatsopano 802.11n kuti zigwiritse ntchito maulendo ena (5 GHz).
- Fufuzani zipangizo zamakono zatsopano zogwiritsidwa ntchito, zomwe zingakhale ndi mwayi waukulu wotsatizana ndi zovomerezeka za 802.11n. Mosakayikira pewani "zisanayambe" kapena "zolemba".
- Onaninso zinthu zomwe zimatsimikiziridwa ndi Wi-Fi Alliance (iwo adzakhala ndi mawonekedwe a Wi-Fi CERTIFIED pamapangidwe awo), pamene izi zimayesedwa kuti zigwirizane ndi kusagwirizana.
- Pomalizira pake, kumbukirani kuti ambiri malo opanda pulogalamu zamtunduwu opanda magetsi ndi mawotchi opanda waya ambiri amakhala othamanga 802.11g kapena b. Ngakhale kuti chipangizo chanu cha 802.11n chatsopano chimagwirizanitsa ndi (mwachitsanzo, chikhoza kugwira ntchito) ma intaneti, idzachita pang'onopang'ono g kapena b speed.
