Ukwenza Ingqiqo yeMilinganiselo eyahlukeneyo yeProtocol ye-WiFi
I-WiFi iteknoloji engena-wire ngokugqwesa kumanethiwekhi angingqi. Kunzima ukuzicingela i-smartphone yakho, i-tablet ye-tablet, i-router, i-repeater okanye nayiphina ifowuni yeselula okanye icomputer ngaphandle kokuba i-WiFi inikwe amandla. Sifakela iifowuni ze- Ethernet ngokukhawuleza.
Enye yezinto zokuqala esiziqinisekisileyo kwiimpawu ngaphambi kokuthenga idivayisi yeselula kukuba ingaba isekela i-WiFi kuba ivula umnyango kwizitshixo, ukuguqulwa, ukuhlaziywa kunye nokunxibelelana, izinto ngaphandle kwesi sixhobo esiza kubakho nto. Kodwa ngaba ukwanele ukujonga i-WiFi? Ukuze ukwazi ngokubanzi ngeemfuno ze-WiFi, ukulinganiselwa, kunye neenzuzo, funda le ngcaciso .
Kwiimeko ezininzi, ewe, kodwa xa kuziwa kwiirdware ezithile ezifana neziphinda kunye nee-routers, kulungile ukujonga iinguqulelo ze-WiFi.
Ukuhambelana phakathi kwamazinga e-WiFi
Indawo yokufikelela eyenza i- WiFi hotspot , njenge-router kunye nesixhobo sokuxhuma, kufuneka ukuba neenguqu ezifanayo ukuxhunywa kunye nokudluliselwa kwimpumelelo. Iphumelela phantse kuwo onke amacala kuba kukho ukulandelelana okubuyiselwayo, kodwa ingxaki ibangqongqo. Umzekelo, ukuba unayo i-Samsung Galaxy yakutsha exhasa i-WiFi entsha yakutsha, ilungele ukuhamba ngesivinini kwiigigabits ngesibini, kodwa idibanisa kwi-intanethi eneendawo zokufikelela ezixhasa i-WiFi yangaphambili kunye neyephuzayo. I-smartphone ayiyi kuba bhetele kunanoma iyiphi enye ifowuni ngokubhekiselele kwisantya soxhumano.
I-WiFi isebenza kwimibonakalo ehlukeneyo yee-frequency-2.4 GHz kunye ne-5 GHz. Olu hlobo lunikeza uluhlu olukhulu kwaye lukhubazeka kakhulu, ngoko ke uxhumano olukhawulezayo, kodwa luthembeke kangako kunokuba lwangaphambili. Ukuba idivaysi esebenzayo kwisiqalo sokuqala izama ukuxhuma komnye osebenza kwimiba yesibili kuphela, ukuxhumeka kuya kuphumelela. Ngethamsanqa, amaninzi amanqaku asebenzayo kunye nobabini.
Ngoko ke, kunokwenzeka ukuba unakho i-hardware elungileyo kunye nesofthiwe yexhumo olukhawulezayo, kodwa oluphuculwayo kwaye oluphantsi kwekhwalithi kuphela ngenxa yokungahambelani kwezinye indawo, apho ungathanda ukutshintsha ezinye izicwangciso, okanye utshintshise i-adapter okanye i sixhobo.
Imigangatho ye-WiFi kunye neenkcukacha zabo
I-WiFi ibizwa ngokuba yi-802.11 protocol . Imilinganiselo eyahlukileyo eyaqhubeka ukuza yonke iminyaka imelwe ngamagama athathwe njengesihlomelo. Nazi ezinye:
802.11 - Intetho yokuqala eyasungulwa ngo-1977. Ngoku ayisasetyenziswa. Isebenza kwi 2.4 GHz.
802.11a - Isebenza kwi-5GHz. Ukukhawuleza 54 Mbps. Unobunzima bokudlula kwiimingcipheko, ngoko ke uluhlu olubi.
802.11b - Isebenza kwi-2.4Ghz ethembekileyo kwaye inika ukuya kuma-11 Mbps. Le nguqulo yafika xa i-WiFi ibhujiswe ekuthandeni.
I-802.11g - Yakhishwa ngo-2003. Sekunjalo, isebenza kwi-2.4GHz ethembekileyo, kodwa yandisa isivinini esikhulu kwi-54 Mbps. Yiyona nto ingcono kwiinguqulelo zangaphambili ze-WiFi ngaphambi kokuba kuqhutywe phambili ukuza ku-2009. Izixhobo ezininzi zisasebenzisa le nguqulo impumelelo kuba ixabiso elincinci lokuphumeza.
802.11n - Utshintsho kwizakhono zobuchwephesha kunye neendlela zokusasaza zandisa isantya ukuya kuma-600 Mbps, kunye nezinye izinto ezintle.
802.11ac - Ukuphuculwa komgangatho wangaphambili, ukwenza usebenziso olungcono lwe-spectrum yeGGz, kunye nokunikela ngesivinini ngaphezu kwe-1 Gbps.
I-802.11ax - Oku kuphucula i-802.11ac ukwandisa i-speedfold, ifikelele kwi-10 Gbps. Kwakhona kwandisa ukwenziwa kwe-WLAN.
