I-Dualband ONU ikwabizwa ngokuba yi-5G onu, kwaye ingabizwa ngokuba yi-AC onu.
Ngoko ke yintoni i-dualband onu?
Ngokwemigangatho yenethiwekhi engenazingcingo, i-dualband onu iya kuba ngcono kune-single-band onu. Iya kuba yeyona onu idumileyo kwixesha elizayo.
IEEE 802.11ac
I-IEEE 802.11ac ngumgangatho wonxibelelwano lwenethiwekhi yekhompyutha engenazingcingo we-802.11 okhulayo, osebenzisa ibhendi yefrikhwensi ye-6GHz (ekwaziwa ngokuba yibhendi yefrikhwensi ye-5GHz) kunxibelelwano lwenethiwekhi yendawo engenazingcingo (i-WLAN). Ngokwethiyori, inokubonelela ubuncinane i-1 Gigabit ngesekhondi yonxibelelwano lwenethiwekhi yendawo engenazingcingo (i-WLAN) yezikhululo ezininzi, okanye ubuncinane i-500 megabits ngesekhondi (500 Mbit/s) yonxibelelwano olunye lwefrikhwensi yokudlulisa uqhagamshelo.
Yamkela kwaye yandisa ingcamango yojongano lomoya ethathwe kwi-802.11n, kuquka: i-bandwidth ebanzi ye-RF (ukuya kuthi ga kwi-160 MHz), imijelo engaphezulu yendawo ye-MIMO (enyuswe ukuya kwi-8), i-MU-MIMO, kunye ne-demodulation ephezulu (i-modulation, ukuya kuthi ga kwi-256QAM). Ingumlandeli onokubakho we-IEEE 802.11n.
Inkampani yethu, iShenzhen HUANET Technology CO., Ltd inokubonelela ngazo zonke iintlobo zee-ont ze-dualband. Nazi ezinye zeemodeli ze-dualband onu.
I-5GHz WiFi isebenzisa ibhendi yefrikhwensi ephezulu ukuze inciphise ukuxinana kweziteshi. Isebenzisa iitshaneli ezingama-22 kwaye ayiphazamisi enye kwenye. Xa ithelekiswa neetshaneli ezi-3 ze-2.4GHz, inciphisa kakhulu ukuxinana kwesignali. Ngoko ke izinga lokudluliselwa kwe-5GHz likhawuleza nge-5GHz kune-2.4GHz.
Ibhendi ye-Wi-Fi ye-5GHz esebenzisa iprotokholi yesizukulwana sesihlanu ye-802.11ac inokufikelela kwisantya sokudlulisela se-433Mbps phantsi kwe-bandwidth ye-80MHz, kunye nesantya sokudlulisela se-866Mbps phantsi kwe-bandwidth ye-160MHz, xa kuthelekiswa nesantya sokudlulisela se-2.4GHz sesantya esiphezulu se-300Mbps. Iphuculwe kakhulu.
Nangona kunjalo, i-5GHz Wi-Fi nayo ineengxaki. Iingxaki zayo zikwibanga lokudluliselwa kwe-intanethi kunye nokukwazi ukugqitha imiqobo.
Ngenxa yokuba i-Wi-Fi yi-electromagnetic wave, indlela yayo ephambili yokusasaza kukusasaza umgca othe tye. Xa idibana nemiqobo, iya kuvelisa ukungena, ukubonakalisa, ukusasaza kunye nezinye izinto. Phakathi kwazo, ukungena yeyona nto iphambili, kwaye inxalenye encinci yesignali iya kwenzeka. Ukubonakalisa kunye nokusasaza. Iimpawu zomzimba zamaza erediyo kukuba okukhona i-frequency iphantsi, ubude bobude bomda, kokukhona ilahleko incinci ngexesha lokusasaza, kokukhona ukugubungela kubanzi, kwaye kulula ukudlula imiqobo; okukhona i-frequency iphezulu, kokukhona ukugubungela kuncinci kwaye kunzima ngakumbi. Hamba ujikeleze imiqobo.
Ke ngoko, isignali ye-5G ene-frequency ephezulu kunye ne-wavelength emfutshane inendawo encinci yokugubungela, kwaye amandla okudlula kwimiqobo awekho ngcono njenge-2.4GHz.
Ngokuphathelele umgama wokudluliselwa, i-2.4GHz Wi-Fi inokufikelela kumlinganiselo ophezulu weemitha ezingama-70 ngaphakathi, kunye nomlinganiselo ophezulu weemitha ezingama-250 ngaphandle. Kwaye i-5GHz Wi-Fi inokufikelela kumlinganiselo ophezulu weemitha ezingama-35 ngaphakathi.
