I-Dualband ONU ikwabizwa ngokuba yi-5G onu, kwaye ingabizwa ngokuba yi-AC onu.
Ke yintoni i-dualband onu?
Ngokomgangatho wenethiwekhi engenazingcingo, i-dualband onu iya kubangcono kune-single-band onu.Iya kuba yeyona onu idumileyo kwixesha elizayo.
IEEE 802.11ac
I-IEEE 802.11ac ngumgangatho ophuhlisayo we-802.11 wenethiwekhi yekhompyutha engenazingcingo, esebenzisa i-6GHz frequency band (ekwaziwa ngokuba yi-5GHz frequency band) yonxibelelwano lwengingqi (WLAN) engenazingcingo.Kwithiyori, inokubonelela ubuncinci be-1 Gigabit ngesibini i-bandwidth ye-multi-station wireless local area network (WLAN) yonxibelelwano, okanye ubuncinane i-500 megabits ngesekhondi (500 Mbit / s) yothungelwano olulodwa lonxibelelwano.
Yamkela kwaye yandise ingcamango yojongano lomoya ephuma kwi-802.11n, kubandakanywa: ububanzi be-RF (ukuya kwi-160 MHz), imilambo yendawo ye-MIMO (inyuke ukuya kwi-8), i-MU-MIMO , kunye nokuchithwa kwe-high-density (modulation, ukuya kwi-256QAM) ).Ingumlandeli onokubakho kwi-IEEE 802.11n.
Inkampani yethu, i-Shenzhen HUANET Technology CO., Ltd inokubonelela ngazo zonke iintlobo zee-onts ezimbini.Nazi ezinye iimodeli ze-onu ezimbini.
I-WiFi ye-5GHz isebenzisa ibhendi yefrikhwensi ephezulu ukuzisa ingxinano encinci yesitishi.Isebenzisa amajelo angama-22 kwaye ayiphazamisi omnye komnye.Xa kuthelekiswa neendlela ezi-3 ze-2.4GHz, kunciphisa kakhulu ukuxinana kweempawu.Ngoko izinga lothumelo lwe-5GHz yi-5GHz ngokukhawuleza kune-2.4GHz.
I-5GHz Wi-Fi frequency band isebenzisa i-protocol yesizukulwana sesihlanu i-802.11ac protocol inokufikelela kwisantya sothumelo se-433Mbps phantsi kwe-bandwidth ye-80MHz, kunye nesantya sothumelo se-866Mbps phantsi kwe-bandwidth ye-160MHz, xa kuthelekiswa ne-2.4GHz isantya esiphezulu izinga le-300Mbps liphuculwe kakhulu.
Nangona kunjalo, i-5GHz Wi-Fi nayo ineentsilelo.Ukusilela kwayo kulele kumgama wothumelo kunye nokukwazi ukunqumla imiqobo.
Ngenxa yokuba i-Wi-Fi iliza lombane, eyona ndlela iphambili yokusasaza kukusasazwa komgca othe ngqo.Xa idibana nemiqobo, iya kuvelisa ukungena, ukubonakalisa, ukuphazamiseka kunye nezinye izinto.Phakathi kwabo, ukungena kuyona nto iphambili, kwaye inxalenye encinci yesignali iya kwenzeka.Ukucinga kunye nokuphazamiseka.Iimpawu ezibonakalayo zamaza kanomathotholo kukuba okukhona kusezantsi i-frequency, kokukhona ubude bamaza, ilahleko encinci ngexesha lokusasaza, kokukhona ukugubungela, kwaye kulula ukudlula imiqobo;okukhona iphezulu i-frequency, incinci i-coverage kwaye inzima ngakumbi.Hamba ujikeleze imiqobo.
Ke ngoko, isiginali ye-5G enezandi eziphakamileyo kunye nobude obufutshane bobude bunendawo encinci yokugubungela, kwaye ukukwazi ukudlula kwimiqobo akulunganga njenge-2.4GHz.
Ngokubhekiselele kumgama wothumelo, i-2.4GHz Wi-Fi inokufikelela kwindawo ephezulu yeemitha ezingama-70 ngaphakathi endlini, kunye nobukhulu obungaphezulu beemitha ezingama-250 ngaphandle.Kwaye i-5GHz Wi-Fi inokufikelela kuphela kukhuselo oluphezulu lweemitha ezingama-35 ngaphakathi.
