Waa maxay dualband ONU

Dualband ONU waxaa sidoo kale loo yaqaan 5G onunu, waxaana sidoo kale loogu yeeri karaa AC onu.

Haddaba waa maxay dualband onnu?

Marka loo eego halbeegga shabakadda wireless-ka, dualband onnu waxa uu ka fiicnaan doonaa onnu hal-band ah.Waxay noqon doontaa onnu ugu caansan mustaqbalka.

IEEE 802.11ac

IEEE 802.11ac waa soo koraya 802.11 halbeeg isgaarsiineed oo kombuyuutar ah oo wireless ah, kaas oo adeegsada xadhkaha soo noqnoqda ee 6GHz (sidoo kale loo yaqaano 5GHz band) ee isgaadhsiinta shabakada deegaanka ee wireless (WLAN).Aragti ahaan, waxay ku siin kartaa ugu yaraan 1 Gigabit bandwidth labaad ee isgaadhsiinta shabakadaha aagga wirelesska ee saldhigyada badan (WLAN), ama ugu yaraan 500 megabits ilbiriqsi kasta (500 Mbit/s) ee hal xabbo oo gudbinta isku xirka.

Waxay qabataa oo balaadhisaa fikradda is-dhexgalka hawada ee laga soo qaatay 802.11n, oo ay ku jiraan: baaxadda ballaaran ee RF (ilaa 160 MHz), durdurro badan oo MIMO ah (oo lagu kordhiyay 8), MU-MIMO, iyo hoos u dhigista cufnaanta sare (modulation, ilaa 256QAM). ).Waa bedelka suurtagalka ah ee IEEE 802.11n.

Shirkaddayada, Shenzhen HUANET Technology CO., Ltd waxay bixin kartaa dhammaan noocyada kala duwan ee dualband onts.Waa kuwan qaar ka mid ah moodooyinka dualband onnu.

5GHz WiFi waxay isticmaashaa band soo noqnoqda sare si ay u keento ciriiri yar.Waxay isticmaashaa 22 kanaal mana faragelin midba midka kale.Marka la barbardhigo kanaalka 3 ee 2.4GHz, waxay si weyn u yaraynaysaa ciriiriga calaamadaha.Markaa xadiga gudbinta 5GHz waa 5GHz ka dhakhso badan 2.4GHz.

Xawaaraha soo noqnoqda ee 5GHz Wi-Fi iyadoo la adeegsanayo nidaamka jiilka shanaad ee 802.11ac waxay gaari kartaa xawaaraha gudbinta 433Mbps ee hoos yimaada xawaaraha 80MHz, iyo xawaaraha gudbinta 866Mbps ee ka hooseeya xawaaraha 160MHz, marka la barbar dhigo heerka gudbinta 2.4GHz ee ugu sarreeya xawaaraha 300Mbps ayaa si weyn loo hagaajiyay.

Si kastaba ha noqotee, 5GHz Wi-Fi sidoo kale waxay leedahay cillado.Dhaliiladeedu waxay ku jirtaa fogaanta gudbinta iyo awoodda ay u leedahay inay ka gudubto caqabadaha.

Sababtoo ah Wi-Fi waa mowjadaha korantada, habka ugu weyn ee faafintiisa waa faafinta khadka tooska ah.Marka ay la kulanto caqabado, waxa ay soo saartaa gal-gal, milicsi, kala fogaansho iyo ifafaale kale.Waxaa ka mid ah, dhexgalka waa kan ugu weyn, qayb yar oo ka mid ah calaamadaha ayaa dhici doona.Milicsiga iyo kala fogaanshiyaha.Astaamaha jireed ee mowjadaha raadiyaha ayaa ah in inta jeer ee ay hooseeyaan, dhererka mawjadaha, ay yaraadaan khasaaraha inta lagu jiro faafinta, balaadhinta tebinta, oo ay fududahay in la dhaafo caqabadaha;Inta jeer ee uu sarreeyo, waa yaraanta daboolka iyo way ka sii adag tahay.Ku wareego caqabadaha.

Sidaa darteed, calaamadda 5G ee leh soo noqnoqoshada sare iyo hirarka dhererka gaaban ayaa leh aag daboolan oo yar, iyo awoodda looga gudbi karo caqabadaha uma fiicna 2.4GHz.

Dhanka fogaanta gudbinta, 2.4GHz Wi-Fi wuxuu gaari karaa daboolka ugu badan ee 70 mitir gudaha, iyo ugu badnaan daboolida 250 mitir bannaanka.Iyo 5GHz Wi-Fi waxay gaari kartaa kaliya daboolka ugu badan ee 35 mitir gudaha.
