A na-akpọkwa Dualband ONU 5G onu, a pụkwara ịkpọ ya AC onu.
Kedu ihe bụ dualband onu?
Dị ka ọkọlọtọ nke netwọk ikuku, dualband onu ga-adị mma karịa otu-band onu.Ọ ga-abụ onu kacha ewu ewu n'ọdịnihu.
IEEE 802.11ac
IEEE 802.11ac bụ ọkọlọtọ nkwurịta okwu netwọọdụ kọmputa ikuku na-emepe emepe 802.11, nke na-eji bandwit 6GHz (nke a makwaara dị ka bandwit 5GHz) maka nkwukọrịta mpaghara mpaghara ikuku (WLAN).Na tiori, ọ nwere ike ịnye opekata mpe 1 Gigabit kwa nke abụọ bandwit maka nkwukọrịta mpaghara mpaghara ikuku ikuku ọtụtụ ọdụ (WLAN), ma ọ bụ opekata mpe 500 megabits kwa nkeji (500 Mbit / s) maka otu bandwidth nnyefe njikọ.
Ọ na-anakwere ma gbasaa echiche ikuku ikuku nke sitere na 802.11n, gụnyere: bandwidth RF obosara (ruo 160 MHz), ọtụtụ iyi MIMO spatial iyi (abawanye na 8), MU-MIMO , na nnukwu njupụta demodulation (modulation, ruo 256QAM). ).Ọ bụ onye nwere ike ịnọchi anya IEEE 802.11n.
Ụlọ ọrụ anyị, Shenzhen HUANET Technology CO., Ltd nwere ike inye ụdị ọ bụla nke dualband onts.Nke a bụ ụfọdụ ụdị onunu dualband.
WiFi 5GHz na-eji eriri ugboro dị elu weta obere mkpọkọ ọwa.Ọ na-eji ọwa 22 ma ọ naghị egbochi ibe ya.E jiri ya tụnyere ọwa 3 nke 2.4GHz, ọ na-ebelata mkpọtụ mgbaàmà.Ya mere ọnụego nnyefe nke 5GHz bụ 5GHz ngwa ngwa karịa 2.4GHz.
Ugboro ugboro 5GHz Wi-Fi na-eji usoro 802.11ac nke ise nke ise nwere ike iru ọsọ ọsọ nke 433Mbps n'okpuru bandwit nke 80MHz, na nnyefe ọsọ nke 866Mbps n'okpuru bandwit nke 160MHz, ma e jiri ya tụnyere 2.4GHz nnyefe ọnụego nke kacha elu. Ọnụọgụ 300Mbps ka emelitere nke ukwuu.
Agbanyeghị, 5GHz Wi-Fi nwekwara adịghị ike.Mmejọ ya dị n'ebe dị anya na-ebufe na ikike ịgafe ihe mgbochi.
N'ihi na Wi-Fi bụ ebili mmiri electromagnetic, usoro mgbasa ozi ya bụ isi bụ ịgbasa ahịrị kwụ ọtọ.Mgbe ọ zutere ihe mgbochi, ọ ga-emepụta ntinye, ntụgharị uche, mgbagwoju anya na ihe ndị ọzọ.N'ime ha, ntinye bụ isi, na obere akụkụ nke mgbaàmà ga-eme.Ntughari uche na diffraction.Ihe e ji mara anụ ahụ nke ebili mmiri redio bụ na ọ na-ebelata ugboro ole, ogologo ebili mmiri na-adịru ogologo oge, na-adị ntakịrị ihe na-efunahụ mgbe a na-ekesa ya, na-agbasawanye ihe mkpuchi ahụ, na-adị mfe karị ịgafe ihe mgbochi;ọnụ ọgụgụ dị elu nke ukwuu, obere mkpuchi na-esikwu ike karị.Gagharịa ihe mgbochi.
Ya mere, akara ngosi 5G nke nwere ogologo oge dị elu na obere ebili mmiri nwere obere mkpuchi mkpuchi, na ikike ịgafe ihe mgbochi adịghị mma dị ka 2.4GHz.
N'ihe gbasara anya nnyefe, 2.4GHz Wi-Fi nwere ike iru mkpuchi kachasị nke mita 70 n'ime ụlọ, yana mkpuchi kachasị nke mita 250 n'èzí.Na 5GHz Wi-Fi nwere ike iru mkpuchi kachasị nke mita 35 n'ime ụlọ.
