Izindinganiso zenethiwekhi ze-IEEE 802.11 zinquma ukuvinjelwa kwamazwi.
Ijubane lenethiwekhi ye-Wi-Fi wireless incike ezintweni eziningana. Njengezinhlobo eziningi zamanethiwekhi wekhompuyutha, i-Wi-Fi isekela amazinga asebenzayo ahlukene, kuye ngokuthi izinga lobuchwepheshe.
Amazinga we-Wi-Fi aqinisekiswe yi-Institute of Electrical and Electronics Engineers (IEEE). I -standard ngayinye ye-Wi-Fi ilinganiswa ngokuvumelana nomkhawulokudonsa womthamo wayo wenethiwekhi. Noma kunjalo, ukusebenza kwamanethiwekhi e-Wi-Fi akuhambisani nalezi zimiso zokufunda.
Imingcele ye-Theoretical vs. Actual Network Speeds
Inethiwekhi ye-802.11b isebenza ngokusheshisa kunamaphesenti angama-50 okuphakama kwayo, cishe 5.5 Mbps. Ama-802.11a nama-802.11g amanethiwekhi ngokuvamile agijima ngokushesha kunama-20 Mbps. Ngisho noma ama-802.11n amanani ku-600 Mbps uma kuqhathaniswa ne- Fast Ethernet yocingo kuma-100 Mbps, uxhumano lwe-Ethernet lungaphumelela ku-802.11n ekusetshenzisweni kwezwe langempela. Noma kunjalo, ukusebenza kwe-Wi-Fi kuyaqhubeka nokuthuthuka ngesizukulwane ngasinye esisha sobuchwepheshe.
Nasi ishadi lesivinqo se-Wi-Fi eliqhathanisa ukuvinjelwa kwangempela kanye nokwaziswa kwamanethiwekhi amaningi we-Wi-Fi wamanje:
| Izinganekwane | Empeleni | |
| 802.11b | 11 Mbps | 5.5 Mbps |
| 802.11a | 54 Mbps | 20 Mbps |
| 802.11g | 54 Mbps | 20 Mbps |
| 802.11n | 600 Mbps | 100 Mbps |
| 802.11ac | 1,300 Mbps | 200 Mbps |
Inombolo ye-802.11ac, evame ukubizwa nge-Gigabit Wi-Fi, inezici ezilandelayo:
- Isivinini esiphezulu se-1.3 Gbps
- Isebenza ku-5-GHz band
- Ixhumeka kuze kufike kumadivaysi amane ngesikhathi esisodwa usebenzisa i-Multi-User, Multi-Input, Multi-Output (MU-MIMO) ubuchwepheshe
Yini Okulandelayo?
Inombolo elandelayo yokuxhumana ye-wireless iyoba yi-802.11ax. Akulindeleke ukuba kuqinisekiswe ngokomthetho yi-IEEE kuze kube ngu-2019. Kuzobe kuhamba ngokushesha kunomlinganiso we-802.11ac, futhi uzokwazi ukusebenza ngisho nalapho isignali ibhekana nokuphazamiseka okukhulu. Ukwengeza, ama-router angu-802.11ax azoba yi-MU-MIMO enikwe amandla; bazokwazi ukuthumela idatha kumadivaysi amaningi-abizwa ukuba abe amadivayisi angu-12-ngesikhathi esifanayo.
Ama-router amaningi amadala athumela idatha kudivayisi eyodwa ngesikhathi esisodwa ngenkathi eshintsha futhi ephuma phakathi kwamadivayisi ngokushesha ngokushesha inkinobho ayitholakali.
Izinto ezilinganiselwe Isivinini sokuxhumeka kwe-Wi-Fi
Ukungafani phakathi kokusebenza kwe-Wi-Fi nokusebenza okusebenzayo kuvela kunethiwekhi ye-protocol , ukuphazanyiswa komsakazo , ukuvimbela ngokomzimba emgqeni wokubona phakathi kwamadivayisi, kanye nebanga phakathi kwamadivayisi.
Ngaphezu kwalokho, njengoba amadivaysi amaningi exhumana kwinethiwekhi ngesikhathi esisodwa, ukusebenza kwawo kunciphisa ngenxa yokuthi ukusebenza komkhawulokudonsa kuyasebenza kodwa futhi nokulinganiselwa kwehadiwe lenethiwekhi.
Ukuxhumeka kwenethiwekhi ye-Wi-Fi isebenza ngejubane eliphakeme kunazo zonke ukuthi amadivaysi womabili, ngokuvamile abizwa ngokuthi ama-endpoints, angase asekele. Ikhompuyutha ye-802.11g exhunywe kumzila we-802.11n, isibonelo, amanethiwekhi esiteshini esingaphansi se-laptop ye-802.11g. Womabili amadivayisi kufanele asekele izinga elifanayo ukuze asebenze ngesivinini esiphezulu.
Abahlinzeki Besevisi Ye-inthanethi Ye-Inthanethi Dlala ku-Speed Speed
Emanethiwekhi asekhaya , ukusebenza kwenethiwekhi ye-intanethi ngokuvamile kuyisici esinqunyelwe ekuvinjeni kwenethiwekhi ekupheleni. Ngisho noma amanethiwekhi amaningi okuhlala asekela ukwabelana ngamafayela ngaphakathi kwekhaya ngesivinini se-20 Mbps noma ngaphezulu, amaklayenti e-Wi-Fi namanje axhuma kwi-inthanethi ngesivinini esivamile esisekelwa abahlinzeki benkonzo ye-intanethi .
Iningi labanikezeli bezinsizakalo ze-intanethi banikeza ngamasevisi amaningi we-intanethi. Ngokushesha uxhumano, lapho uhola khona.
Ukubaluleka okwandayo kokuvinjelwa kwenethiwekhi
Ukuxhumeka okusheshayo kwe-speed kwaba okubaluleke kakhulu njengoba ividiyo yokusakaza ithola ukuthandwa. Ungase ubhalisele ku-Netflix, Hulu, noma enye insizakalo yokusakaza ividiyo, kodwa uma uxhumano lwakho lwe-intanethi nenethiwekhi engakwazi ukuhlangabezana nezidingo ezincane zejubane, ngeke ubukele amabhayisikobho amaningi.
Okufanayo kungashiwo ngezinhlelo zokusebenza zokusakaza ividiyo. Uma ubukela i-TV nge- Roku , i- Apple TV , noma okunye okunamathiselwe okukhangayo kwezokusakaza, uchitha isikhathi sakho esiningi sokubuka ithelevishini kuzinhlelo zeziteshi zezentengiselwano nezinsizakalo ze-premium.
Ngaphandle kwenethiwekhi esheshayo esheshayo, lindela ukubhekana nekhwalithi yevidiyo empofu kanye nama-pauses avamile ukuze uhlasele.
Isibonelo, i-Netflix incoma isivinini sokuxhumeka kwe-broadband se-1.5 Mbps kuphela, kodwa sincoma ukuvinjelwa okuphakeme kwekhwalithi ephakeme: 3.0 Mbps ngekhwalithi ye-SD, 5.0 Mbps ngekhwalithi ye-HD, nama-Mb Mbhidi we-Ultra HD.
Indlela Yokuhlola Isivinini Senethiwekhi Yakho
Umnikezeli wakho wesevisi ye-intanethi anganikeza isevisi yokuhlola ijubane inthanethi. Vele ungene ngemvume ku-akhawunti yakho, iya ekhasini lokuvinjelwa kokuxhumana, uphinde usebenzise le nsizakalo. Phinda uhlolo ngezikhathi ezihlukahlukene zosuku ukuze ufike esiteji sokulinganisela.
Uma umnikezeli wakho wesevisi ye-intanethi enganikezeli ukuhlolwa kwejubane, iningi lezinsizakalo ze-intanethi ze-intanethi zitholakalayo ukuhlola isivinini sakho senethiwekhi .
