Ukubheka izinzuzo nokulinganiselwa kwamafreedom amabili we-Wi-Fi
Amanethiwekhi we-Wi-Fi asebenzisa izimpawu zomsakazo kumabutho ama-2.4 GHz noma ama-GHz angu-5. Lezi zinamba zikhangiswa ngokucacile emaphaketheni yomkhiqizo, kodwa izincazelo zabo ngokuvamile aziqondakali kahle.
Wonke amadivayisi we-Wi-Fi yanamuhla asekela ukuxhumana okungama 2.4 Ghz, ngenkathi ezinye izinto zisekela kokubili. Ama- router asekhaya asekhaya asetshenziswa ama- 2.4 GHz nama-5 GHz ama-radios abizwa ngokuthi ama- router angama- double-band angenantambo .
Ukuhlukaniswa okubalulekile okwenziwe kuphakathi kwenethiwekhi ye-WiFi nenethiwekhi yakho engenantambo yefoni yeselula. Lezi zobuchwepheshe obuhlukile kakhulu, futhi zingase zidideke nakakhulu uma uxoxa nge-GHz ye-WiFi band band kanye nobuchwepheshe bokuxhumana benethiwekhi ye-5G , esikhundleni sika- 4G .
Lapha sizoxoxa ngezixhumanisi ze-WiFi ongasetha ekhaya lakho usebenzisa i-router, futhi amaqembu womvamisa amabili asetshenziswa nokuthi ingabe inethiwekhi yomhlaba ye-double-band ingahle isetshenziswe ukuze ithathe inzuzo enkulu kunazo zonke zomculo womabili. Lokhu akubandakanyi ubuchwepheshe benethiwekhi yeselula ye-Smartphones namanye amadivayisi.
I-GHz ne-Network Speed
Ukuxhumana kwenethiwekhi ye-WiFi kuza ezinhlobonhlobo ezimbalwa. La mazinga we-WiFi achaza ukuthuthukiswa kokuxhumana nobuchwepheshe. Izindinganiso zikhona (ngokulandelana kokukhululwa, endala kuya ezisha):
- 802.11a
- 802.11b
- 802.11g
- 802.11n
- 802.11ac
Lezi zindinganiso zixhunywe kumafomu we-GHz band, kepha lokhu akukhulunywe ngakho ngokuningiliziwe lapha, kepha kubhekiselwa kubo.
Inethiwekhi ye-GHz engama-5 ingathatha idatha engaphezu kwenethiwekhi ye-2.4 GHz ngakho-ke ngokusemthethweni ishesha (ukucabanga ukuthi amandla kagesi kumsakazo ophezulu wegridi igcinwa ezingeni eliphakeme). Ama-radios angu-5GHz asekela kakhulu izinga eliphezulu lemininingwane yedatha kumazinga wenethiwekhi 802.11n no- 802.11ac . Amadivayisi asekhaya akhiqiza noma adle inani elikhulu kunazo zonke lomgwaqo wenethiwekhi, njengama-units esakaza ukusakaza noma ama-console wegeyimu, ngokuvamile agijima ngokushesha kunamaxhumanisi angu-5 GHz.
I-GHz ne-Network Range
Ukuphakama kwemvamisa yesignali engenawo ucingo, kufushane ububanzi bayo. 2.4 amanethiwekhi angenantambo angama-GHz ngakho-ke ahlanganisa uhla olubanzi kakhulu kunamanethiwekhi we-GHz angu-5. Ngokuyinhloko, amasignali amafremu ama-5 GHz ayangena ngaphakathi ezintweni eziqinile cishe kanye namasignali angu-2.4 GHz, enciphisa ukufinyelela kwabo emakhaya.
Ukungafani kwe-GHz neNethiwekhi
Ungabona ukuthi amanye amafoni angenawo ucingo, ama-opener door door, kanye nezinye izinto zokusebenza zasemakhaya nazo zisebenzisa ukuguqulwa kwe-2.4 GHz. Ngenxa yokuthi lolu hlu lwamagremu luvame ukusetshenziswa emikhiqizo yabathengi, ligcwele izibonakaliso. Lokhu kungenza kube lula ukuthi inethiwekhi yekhaya ye-2.4 GHz izobe iphazamiseka emakhonjeni kunokuba inethiwekhi yasekhaya ye-5 GHz izobe ikhona. Lokhu kungancipha futhi kuphazamise isivinini senethiwekhi ye-WiFi kulezi zimo.
I-GHz nezindleko
Abanye abantu bakholelwa ngephutha ukuthi ubuchwepheshe benethiwekhi ye-GHz buyi-entsha noma ngandlela-thile busha ngaphezu kwe-2.4 GHz ngoba ama-router ekhaya ase-5 GHz ngokuvamile atholakale ngemuva kwalabo abasebenzisa ama-radios 2.4 GHz. Eqinisweni, zombili izinhlobo zokubonisa zikhona iminyaka eminingi futhi zombili ubuchwepheshe obuqinisekisiwe.
Ama-Routers anika ama-ray angu-2.4GHz no-5GHz ngokuvamile ayabiza kunalabo abanikeza ama-radios angu-2.4GHz kuphela.
Okubalulekile
I-GHz ne-2.4 GHz yizikhathi ezihlukahlukene zokungena ezingenantambo ezingenazintambo eziba nenzuzo yezinethiwekhi zokuxhumana ze-Wi-Fi, futhi lezi zinzuzo zingancika ekutheni uhlela kanjani inethiwekhi yakho-ikakhulukazi uma ucabangela ukuthi kude kangakanani nokuthi yikuphi okuvimbela isignali yakho ukuthi kungadingeka ukuthi ifinyelele. Uma udinga ububanzi obuningi nokungena okuningi ngezindonga, i-2.4GHz izosebenza kangcono; Kodwa, ngaphandle kwalokhu okulinganiselwe, i-5 GHz cishe iyoba yisinqumo esisheshayo.
Okubizwa okuthiwa ama-hardware we-band amabili afana nalawo atholakala kuma-router angu-802.11ac ahlanganisa okungcono kakhulu kokubili izinhlobo ze-hardware ngokuhlanganisa izinhlobo zombili zamarediyo, isisombululo esithandayo esiphuthumayo sokwenza inethiwekhi ekhaya.
