I-Dualband ONU ibizwa nangokuthi i-5G onu, futhi ingabizwa nangokuthi i-AC onu.
Ngakho-ke iyini i-dualband onu?
Ngokwezinga lenethiwekhi engenantambo, i-dualband onu izoba ngcono kune-single-band onu. Izoba yi-onu ethandwa kakhulu esikhathini esizayo.
I-IEEE 802.11ac
I-IEEE 802.11ac iyindinganiso yokuxhumana kwenethiwekhi yekhompyutha engenantambo engu-802.11 ethuthukayo, esebenzisa ibhendi yemvamisa engu-6GHz (eyaziwa nangokuthi ibhendi yemvamisa engu-5GHz) yokuxhumana kwenethiwekhi yendawo engenantambo (i-WLAN). Ngokwethiyori, inganikeza okungenani i-bandwidth eyi-1 Gigabit ngomzuzwana yokuxhumana kwenethiwekhi yendawo engenantambo (i-WLAN) eneziteshi eziningi, noma okungenani ama-megabit angu-500 ngomzuzwana (500 Mbit/s) yokuxhumana okukodwa kokudlulisa uxhumano.
Yamukela futhi yandisa umqondo wesixhumi somoya osuselwa ku-802.11n, okuhlanganisa: i-bandwidth ebanzi ye-RF (kufika ku-160 MHz), imifudlana eminingi yesikhala se-MIMO (enyuswe yaba ngu-8), i-MU-MIMO, kanye nokususwa kobuningi obuphezulu (ukuguqulwa, kufika ku-256QAM). Ingumlandeli ongaba khona we-IEEE 802.11n.
Inkampani yethu, i-Shenzhen HUANET Technology CO., Ltd ingahlinzeka ngazo zonke izinhlobo zama-ont e-dualband. Nazi ezinye izinhlobo zama-onu e-dualband.
I-WiFi engu-5GHz isebenzisa ibhendi yemvamisa ephezulu ukuletha ukuminyana okuncane kweziteshi. Isebenzisa iziteshi ezingu-22 futhi ayiphazamisi. Uma iqhathaniswa neziteshi ezintathu ze-2.4GHz, inciphisa kakhulu ukuminyana kwesignali. Ngakho izinga lokudlulisa le-5GHz lishesha nge-5GHz kune-2.4GHz.
Ibhendi yemvamisa ye-Wi-Fi engu-5GHz esebenzisa iphrothokholi yesizukulwane sesihlanu ye-802.11ac ingafinyelela isivinini sokudlulisa esingu-433Mbps ngaphansi komkhawulokudonsa ongu-80MHz, kanye nesivinini sokudlulisa esingu-866Mbps ngaphansi komkhawulokudonsa ongu-160MHz, uma kuqhathaniswa nesilinganiso sokudlulisa esingu-2.4GHz sesilinganiso esiphezulu esingu-300Mbps.
Kodwa-ke, i-Wi-Fi ye-5GHz nayo inezinkinga. Izinkinga zayo zisebangeni lokudlulisa kanye nekhono lokudlula ezinkingeni.
Ngenxa yokuthi i-Wi-Fi iyigagasi likagesi, indlela yayo eyinhloko yokusabalalisa iwukusabalalisa umugqa oqondile. Uma ihlangabezana nezithiyo, izokhiqiza ukungena, ukubonakalisa, ukusabalalisa kanye nezinye izinto. Phakathi kwazo, ukungena yiyona eyinhloko, futhi ingxenye encane yesignali izokwenzeka. Ukuzindla kanye nokusabalalisa. Izici zomzimba zamagagasi omsakazo ukuthi lapho imvamisa iphansi, ubude be-wavelength buyanda, ukulahlekelwa kuncane ngesikhathi sokusabalalisa, ukumbozwa kubanzi, futhi kulula ukudlula izithiyo; lapho imvamisa iphakama, ukumbozwa kuncane futhi kuba nzima kakhulu. Hamba uzungeze izithiyo.
Ngakho-ke, isignali ye-5G enemvamisa ephezulu kanye nobude obufushane inendawo encane yokumboza, futhi ikhono lokudlula ezinkingeni alilihle njenge-2.4GHz.
Ngokuphathelene nebanga lokudlulisa, i-Wi-Fi engu-2.4GHz ingafinyelela ukumbozwa okuphezulu kwamamitha angu-70 ngaphakathi, kanye nokumbozwa okuphezulu kwamamitha angu-250 ngaphandle. Futhi i-Wi-Fi engu-5GHz ingafinyelela ukumbozwa okuphezulu kwamamitha angu-35 ngaphakathi.
