Kuita Nzwisiso YeMimwe Mitemo ye WiFi Protocol
WiFi ndiyo inyanzvi isina uteresi nehupamhizha hwematare emunharaunda. Zvakaoma kufungidzira smartphone yako, tablet PC, router, repeater kana chero imwe foni yesimbi kana kakombiyuta yedhidhiyo pasina WiFi inobvumira. Tiri kutaurirana zvishoma nezvishoma tambo dzeEthernet.
Chimwe chezvinhu zvekutanga zvatinovimbisa mumatauriro asati atenga foni yeserosheni ndechokuti inotsigira WiFi nokuti inozarura musuo wezvivako, tweaks, zvinyorwa, nekukurukurirana, zvinhu zvisingashandisirwi. Asi zvakakwana here kutarisa WiFi? Kuti uwane zvakawanda maererano neWiFi zvakakosha, zvisingakwanisi, uye zvinobatsira, verenga tsanangudzo iyi .
Muzviitiko zvizhinji, hongu, asi kana zvasvika kune hardware chaiyo sevanodzokorora uye routers, zvakanaka kuti uone maWiFi versions.
Kubatirana pakati peFiFi Standards
Nzvimbo yekuwana iyo inogadzira hotspot yeFiFi , yakadai se router, uye chikwata chinobatanidza, inoda kuva nemashanduri akafanana ekubatanidza uye kutamisa kubudirira. Inobudirira munharaunda yese mamiriro ezvinhu nokuti kune kudzokera kunoenderana, asi dambudziko riri mumiganhu. Semuenzaniso, kana iwe une Samsung Galaxy yakapfuura inotsigira shanduro yemazuva eWiFi, yakagadzirira kugadzirisa kufamba kwegigabits kwechipiri, asi iri kuisungirira kune inetaneti ine nzvimbo yekuwana iyo inotsigira yekare uye inononoka yeWiFi, yako inopenya smartphone haizovi nani kupfuura chero imwe foni maererano nehutano hwekufambisa.
WiFi inoshanda mune zvakasiyana zvakasiyana-siyana zvinoratidzika - 2.4 GHz uye 5 GHz. Izvozvo zvinopa ruzivo rwakakura uye haruna rutivi rwakaremara, nokudaro nekukurumidza kushamwaridzana, asi harisi kutendeseka kudarika kare. Kana chigadzirwa chinoshanda pakutanga chokutanga chinotanga kushamwaridzana kune chinoshanda pachikamu chechipiri chete, kubatana hakuzobudiriri. Nenzira yakanaka, zvigadzirwa zvakawanda zvemazuva ano zvinoshanda pamwe chete nemitambo yese.
Izvozvi, saka, zvinoita kuti iwe unogona kuva hardware yakanaka uye software yekukurumidza kushamwaridzana, asi iyo inononoka uye yakaderera hutsika chete nekuda kwekusawirirana kumwe pane imwe nzvimbo, pane izvo zvingave iwe unoda kuchinja zvimwe zvirongwa, kana kungoshandura imwe adapta kana chigadzirwa.
IWiFi Standards uye Zvavanotaura
WiFi inyanzvi inonzi inonzi 802.11 protocol . Maitiro akasiyana akaramba achiuya mumakore ese aya anomiririrwa nechezasi mabhuku sechinhu chakakwana. Heano mamwe acho:
802.11 - Shanduro yekutanga yakatanga muna 1977. Ikozvino haisisiri kushandiswa. Inoshanda pa 2.4 GHz.
802.11a - Inoshanda pa5GHz. Speed 54 Mbps. Une dambudziko rekupfuura nepakati pezvipingamupinyi, saka rinenge risina kunaka.
802.11b - Inoshanda pane yakavimbika 2.4Ghz uye inopa kusvika 11 Mbps. Iyi inguva yakauya apo WiFi yakaputika pakuzivikanwa.
802.11g - Yakabudiswa muna 2003. Kunyange zvakadaro, inoshanda pamatare anonzi 2.4GHz, asi yakawedzera nguva yakareba kusvika 54 Mbps. Ndiyo yakanakisisa mumashanduro aya epakuvamba yeWiFi mushure mekukwira kukuru kwekuuya kuuya muna 2009. Zviyero zvizhinji zvichiri kushandura iyi shanduro kubudirira nokuti inodhura kushandiswa.
802.11n - Kuchinja mu network networkities uye nzira dzekutengesa dzinowedzera kukurumidza kusvika kusvika 600 Mbps, pamwe nezvimwe zvinobatsira.
802.11ac - Kuvandudzika kwemuenzaniso wekare, kushandiswa kwakanaka kwema 5Ghz spectrum, uye kupa nokukurumidza zvakanyanya kupfuura 1 Gbps.
802.11ax - Izvi zvinovandudza 802.11ac kuwedzera yakawandisa zvakakurumidza, inoreti kusvika kusvika 10 Gbps. Inowedzerawo kubudirira kweWLANs.
