Nekuvandudzwa kweInternet, masevhisi akadai semifananidzo yepamhepo, mavhidhiyo uye kutenderera midhiya akaisa yakakwirira bandwidth zvinodiwa pane isina waya yeLAN tekinoroji.inozivikanwawo se "High Efficiency Wireless Standard".
Saizvozvo,802.11axyakagadzirirwa kugadzirisa dambudziko rekusimba kwetiweki, iro rave nyaya huru munzvimbo dzakasimba senge nhandare dzendege, zviitiko zvemitambo uye makampasi sezvo Wi-Fi yeruzhinji yave yakakurumbira.Saka ndedzipi dzakanyatsoitika tekinoroji ye11ax sechizvarwa chitsva cheWiFi protocol?
1. wifi6 inotsigira 2.4G uye 5G
Iyo 802.11ax protocol yakavakirwa pamabhendi maviri efrequency, 2.4GHz uye 5GHz.Iri bhendi rembiri harisi rakasiyana protocol kune akasiyana mabhendi mabhendi senge ac dual band routers, asi demo protocol pachayo inotsigira maviri frequency mabhendi.Izvi zviripachena zvinoenderana neazvino maitiro eIoT, smart imba uye zvimwe zviitiko.Kune mimwe michina yemumba yakangwara isingade yakakwira bandwidth, unogona kushandisa 2.4GHz bhendi kuti ubatanidze kuti uve nechokwadi chekutapurirana chinhambwe, ukuwo michina inoda kumhanyisa-kumhanya, shandisa bhendi re5GHz.
2. Tsigira 1024-QAM, yakakwirira data data
Panyaya yemodulation WiFi 5 ndeye 256-QAM uye WiFi-6 ndeye 1024-QAM, yekare inotsigira huwandu hwemadhata mana emvura apo iyo yekupedzisira inotsigira huwandu hwe8. Naizvozvo, WiFi 5 inogona kuwana theoretical throughput ye3.5Gbps, nepo WiFi 6 inogona kuwana inoshamisa 9.6Gbps.
3. Tsigiro yeshanduro yakazara yeMU-MIMO
MIMO inoreva kuti Multiple Input Multiple Output tekinoroji, zvinoreva kushandiswa kweantenna akawanda ekutepfenyura uye kugamuchira antenna pane inotapurirana uye inogamuchira inopera zvichiteerana, kuitira kuti masaini akwanise kutapurirwa uye kugashirwa kuburikidza nemaantenna akawanda pane anotumira uye anogashira anopera kuti awane yakakwirira mushandisi mitengo pa. mari shoma, nokudaro kuvandudza hutano hwekukurukurirana.Muchokwadi, tekinoroji yeMIMO yakaunzwa neIEEE mu802.11n protocol era, uye MU-MIMO tekinoroji inogona kunzwisiswa seyakakwidziridzwa kana yakawanda-mushandisi vhezheni yayo.
Mukutaura kwe layman, iyo yapfuura MIMO pa802.11n inogona kungotsanangurwa seSU-MIMO, uko yechinyakare SU-MIMO router masiginecha anounzwa mudenderedzwa, achitaurirana ega neInternet maturusi ekushandisa mukurongeka kwepedyo.Kana michina yakawandisa yakabatana, pachava nemidziyo yakamirira kutaurirana;kana uine 100MHz yebandwidth, maererano nemusimboti we "imwe chete inogona kushanda panguva", kana paine michina mitatu yakabatana kunetiweki panguva imwe chete, mudziyo wega wega unogona kuwana anenge 33.3MHz yebandwidth, uye imwe yacho. 66.6MHz haina basa.Imwe 66.6MHz haina kushandiswa.Izvi zvinoreva kuti iyo yakawanda michina yakabatana kune imwecheteyo Wi-Fi nharaunda, iyo diki bandwidth inoyerwa kunze, iyo yakawanda zviwanikwa inoraswa uye inononoka network kumhanya.
Iyo MU-MIMO router yakasiyana, sezvo iyo MU-MIMO routing chiratidzo yakakamurwa kuita zvikamu zvitatu mudura renguva, frequency domain uye airspace domain, sekunge masaini matatu akasiyana anoburitswa panguva imwe chete, uye anogona kushanda nemidziyo mitatu pa. nguva imwe chete;kunyanya kukosha kutaurwa ndeyekuti, sezvo zviratidzo zvitatu zvisingakanganisi kune mumwe nemumwe, saka zviwanikwa zvebandwidth zvakagamuchirwa nemudziyo wega wega hazvina kukanganisa, uye zviwanikwa zvinowedzera.Kubva pakuona kwe router, chiyero chekufambisa data chinowedzerwa nechikamu chetatu, kuvandudza kushandiswa kwezviwanikwa zvetiweki uye nekudaro kuve nechokwadi chekubatanidza Wi-Fi isina kukanganiswa.
4. OFDMA tekinoroji
OFDM, kana Orthogonal Frequency Division Multiplexing, chirongwa chekutakura chinotakura zvakawanda chakagadzirwa kubva kune akawanda-anotakura modulation ane kuderera kwekuita kuomarara uye kuwanda kwehuwandu hwekushandisa.Kuenzanisira nemuenzaniso wakajeka: ngatiti isu iye zvino tine motokari dzakawanda dzinobva kuA kusvika kuB. Kusati kwashandiswa teknolojia yeOFDM, mugwagwa uri mugwagwa, motokari dzose dzinofamba-famba uye dzinoputika, semugumisiro, hapana anogona kukurumidza. .Iye zvino neOFDM tekinoroji, mugwagwa muhombe wakakamurwa kuita nzira dzakawanda uye munhu wese anotyaira zvinoenderana nemukoto, izvo zvinogona kuwedzera kumhanya uye kuderedza kupindirana pakati pemotokari.Panguva imwecheteyo, kana paine mota dzakawanda munzira iyi, dzakaenzaniswa zvishoma kune iyo nzira ine mota shoma, izvo zviri nyore kubata.
tekinoroji yeOFDMA yakavapo kubva kuOFDM nekuwedzera tekinoroji yekuwana yakawanda (kureva kuti yakawanda-mushandisi) kwairi.
Mhinduro yeOFDM ndeyekutumira rori kamwe kune mutengi wega wega.Pasinei nehuwandu hwekutakura, rwendo rumwe chete runotumirwa, izvo zvisingadzivisiki zvinoguma nevhavha isina chinhu.Mhinduro yeOFDMA, kune rumwe rutivi, inotumira akawanda maodha pamwe chete, ichibvumira marori kuti arove mugwagwa akazara zvakakwana sezvinobvira, zvichiita kuti zvekufambisa zvinyatsoshanda.
Kwete izvozvo chete, asi mhedzisiro yeOFDMA uye MU-MIMO inogona kukwidziridzwa pasi peWiFi6.Vaviri ava vanopa hukama hwekuwedzerana, neOFDMA ichikodzera kufambisa kwakafanana kwemapaketi madiki kuvandudza mashandisirwo echiteshi uye kutapurirana zvakanaka.MU-MIMO, kune rumwe rutivi, inokodzera kufambisa kwakafanana kwemapaketi makuru, kuwedzera bandwidth inoshanda yemushandisi mumwechete uye zvakare kuderedza latency.
Kuenzanisa kwe5G uye WIFI6
1. Mamiriro ekushandisa:
5G LTE ma routers anoshandiswa mune zvakasiyana siyana zvekushandisa, senge
1. Kufambisa: 5G LTE ma routers anogona kushandiswa kupa yakakwirira-kumhanya internet yekubatanidza kumotokari dzakadai semabhazi, zvitima uye marori.Vanogonesa vafambi kuti vasvike paInternet uye vatepfenyure vhidhiyo vachiri munzira.
2. Simba: 5G LTE ma routers anogona kushandiswa kupa kukurumidza-kumhanya kweInternet kune nzvimbo dziri kure dzesimba dzakadai semapurazi emhepo nemafuta emafuta.Ivo vanogonesa vashandi kuwana chaiyo-nguva data uye kutaurirana nevanoshanda navo.
3. Kuchengetedzwa kwevanhu vose: 5G LTE routers inogona kushandiswa kupa yakakwirira-yekukurumidza Internet yekubatanidza kune vanopindura zvekukurumidzira semapurisa nevanodzima moto.Ivo vanogonesa vanopindura kuti vawane ruzivo rwakakosha uye kutaurirana nevanoshanda navo mumamiriro ekukurumidzira.
4. Retail: 5G LTE routers inogona kushandiswa kupa yakakwirira-yekukurumidza Internet yekubatanidza kune zvitoro zvekutengesa, zvichiita kuti vape ruzivo rwekutenga rwemunhu uye real-time inventory management.
Nepo WiFi6 ichinyanya kutariswa mukati memukati mapfupi-renji yekuvhara, Wi-Fi6 isarudzo yakanaka kumahofisi emakambani.Kupa mamwe sarudzo kuti mabhizinesi ave akangwara.Pamusoro pezvo, kubva pamaonero ekushandiswa kwevashandisi vekumba, wifi6 chete ndiyo inogona kuburitsa kushanda kwakanyanya kwe5G.
2. Kubva pahutano hwehutano
Chiyero chakanaka chewifi6 i9.6Gbps, nepo chiyero chakanaka che5G chiri 10Gbps, kwete misiyano yakawanda pakati pezviyero zviviri zvakakodzera.
Kuvharwa, kufukidzwa kwakabatana nesimba rekufambisa, Wi-Fi6 APs inovhara anenge 500 kusvika 1000 square metres;yekunze 5G base station inogona kutumira kusvika ku60W, kuvharika kwayo ikiromita nhanho.Panyaya yenzvimbo yekuvhara, 5G yakakwirira kune wifi6.
Indoor mumwechete mushandisi ruzivo: Wi-Fi6 APs inogona kusvika ku8T8R, ine mwero chaiwo weinenge 3Gbps-4Gbps.yakajairika yemukati 5G diki base station antenna inowanzo 4T4R, ine chiyero chaicho che1.5Gbps-2Gbps.saka, single device performance Wi-Fi6 ichapfuura 5G.
3. Mari yekuvaka:
Manetiweki e5G anofanirwa kusimbiswa nekuronga kwepedyo uye simulation nekuda kwekupera kuri nyore kwemasaini.Pamusoro pezvo, hunhu hwe5G mabhendi uye wavelengths zvinoda 5G base zviteshi kuti zviite dense, zvichikonzera kudhura kwenzvimbo yekuisa chiteshi.
Kusiyana neizvi, kukwidziridzwa kwewifi6 kunongoda kukwidziridzwa kweiyo main chip, uye kutumira kunogona kuwanikwa nekungotenga yakazara Wi-Fi6 AP kana fiber iri mumba kana mubhizinesi.
5G uye Wifi6 imwe neimwe ine simba rayo uye kusasimba kwayo.5G iine network network ine ma frequency band akatenderwa, nepo WiFi iri bhendi risingatenderwe, rakafanana netiweki yega yega, uye kunyangwe 5G ikawana bhendi risina mvumo, zvakaoma kudzikisa mutengo wenzvimbo dzekuwana nekuda kwe kusagadzikana kwetiweki uye kwenguva pfupi, saka WiFi 6 inova mubatsiri wakanaka kune ichi chidimbu chemukati IoT.
Semuenzaniso, kana tikaenzanisa tekinoroji yekukurukurirana neyekufambisa, 5G yakafanana nendege inokwanisa kukurumidza kutakura tsamba kubva kune rimwe guta kuenda kune rimwe, asi haikwanise kukubatsira kutora zvekutora mukati me1 km, uye zviri nani kushandisa iyo yepamusoro-soro. motokari yemagetsi kunotora takeaways.
Tikugashirei kushanyira webhusaiti yeZBT kuti uwane rumwe ruzivo nezve ma routers asina waya:
