I-Dualband ONU ibizwa nangokuthi i-5G onu, futhi ingaphinda ibizwe nge-AC onu.
Ngakho yini i-dualband onu?
Ngokwezinga lenethiwekhi engenantambo, i-dualband onu izoba ngcono kune-single-band onu.Kuzoba i-onu edume kakhulu esikhathini esizayo.
IEEE 802.11ac
I-IEEE 802.11ac iyindinganiso yokuxhumana yenethiwekhi yekhompyutha engenantambo engu-802.11, esebenzisa ibhendi yefrikhwensi engu-6GHz (eyaziwa nangokuthi i-5GHz frequency band) yokuxhumana kwenethiwekhi yendawo engenantambo (WLAN).Ngokombono, ingahlinzeka okungenani ngomkhawulokudonsa ongu-1 we-Gigabit ngesekhondi yokuxhumana yenethiwekhi yendawo engenantambo yeziteshi eziningi (i-WLAN), noma okungenani ama-megabhithi angu-500 ngomzuzwana (500 Mbit/s) kumkhawulokudonsa owodwa wokudlulisa uxhumano.
Yamukela futhi yandise umqondo wesixhumi esibonakalayo somoya osuselwe ku-802.11n, okuhlanganisa: ububanzi be-RF bandwidth (kufika ku-160 MHz), imifudlana eminingi yendawo ye-MIMO (ekhuphuke yafinyelela ku-8), MU-MIMO , Kanye nokwehliswa kwe-high-density (modulation, kufika ku-256QAM ).Kungaba umlandeli we-IEEE 802.11n.
Inkampani yethu, i-Shenzhen HUANET Technology CO., Ltd ingahlinzeka ngazo zonke izinhlobo zama-onts ama-dualband.Nawa amamodeli we-dualband onu.
I-5GHz WiFi isebenzisa ibhendi yefrikhwensi ephezulu ukuletha ukuminyana kwesiteshi okuncane.Isebenzisa iziteshi ezingama-22 futhi ayiphazamisi enye nenye.Uma kuqhathaniswa namashaneli angu-3 we-2.4GHz, kunciphisa kakhulu ukuminyana kwesignali.Ngakho izinga lokudlulisela le-5GHz liyi-5GHz ngokushesha kune-2.4GHz.
Ibhendi yefrikhwensi ye-5GHz Wi-Fi esebenzisa iphrothokholi yesizukulwane sesihlanu engu-802.11ac ingafinyelela isivinini sokudlulisela esingu-433Mbps ngaphansi komkhawulokudonsa ongu-80MHz, kanye nesivinini sokudlulisela esingu-866Mbps ngaphansi komkhawulokudonsa ongu-160MHz, uma kuqhathaniswa nezinga lokudlulisela elingu-2.4GHz eliphakeme kakhulu izinga le-300Mbps selithuthukiswe kakhulu.
Noma kunjalo, i-5GHz Wi-Fi nayo inokushiyeka.Ukushiyeka kwayo kusebangeni lokudlulisela kanye nekhono lokunqamula izithiyo.
Ngenxa yokuthi i-Wi-Fi iyigagasi kagesi, indlela yayo eyinhloko yokusabalalisa ukusakazwa komugqa oqondile.Uma ihlangabezana nezithiyo, izokhiqiza ukungena, ukucabangela, ukuhlukanisa nezinye izenzakalo.Phakathi kwabo, ukungena yiyona eyinhloko, futhi ingxenye encane yesignali izokwenzeka.Ukucabangisisa kanye nokwehluka.Izici ezingokomzimba zamaza omsakazo ziwukuthi lapho imvamisa yehlisa, ubude begagasi buyinde, ukulahlekelwa kuncane ngesikhathi sokusakazeka, kuyanda ukusabalala, futhi kuba lula ukudlula izithiyo;ukuphakama kwemvamisa, kuncane ukumbozwa futhi kuba nzima kakhulu.Hamba uzungeze izithiyo.
Ngakho-ke, isignali ye-5G ene-frequency ephezulu kanye ne-wavelength emfushane inendawo encane yokumboza, futhi ikhono lokudlula izithiyo alilihle njenge-2.4GHz.
Mayelana nebanga lokudlulisela, i-2.4GHz Wi-Fi ingafinyelela ukumbozwa okuphezulu kwamamitha angama-70 ngaphakathi endlini, kanye nokumbozwa okuphezulu okungamamitha angama-250 ngaphandle.Futhi i-5GHz Wi-Fi ingafinyelela kuphela ukumbozwa okuphezulu kwamamitha angama-35 ngaphakathi endlini.
