Chaizvoizvo, kuenzanisa pakati pekuita 5G neWiFi haina kunyatso kufanira.Nekuti 5G ndiyo "chizvarwa chechishanu" chenharembozha yekutaurirana, uye WiFi inosanganisira akawanda "chizvarwa" shanduro dzakadai se802.11/a/b/g/n/ac/ad/ax, zvakada kufanana nekusiyana kweTesla neChitima. .

Zvakawanda, kubva pachiyero chimwe chete, musiyano uripo pakati penharembozha yekutaurirana system (XG, X=1,2,3,4,5) neWifi yatinoshandisa nhasi?
Musiyano uripo pakati peXG neWifi
Semushandisi, ruzivo rwangu nderwekuti Wifi yakachipa zvakanyanya kupfuura XG, uye kana tikaregeredza mutengo weiyo wired Broadband uye ma routers, tinogona kutofunga kuti kushandisa wifi kubatana neInternet ndeyemahara.Nekudaro, kazhinji, mitengo inogona kungoratidza zvimwe zvehunyanzvi zvinhu.Kana iwe ukatora diki diki network woiwedzera munyika uye pasirese, ndeye XG.Asi pane musiyano mukuru pakati pehukuru-hukuru uye diki-mwero.
Kuti titsanangure kusiyana kwazviri, tinofanira kutanga nezvinodiwa.
Demand musiyano
Competitive
Panyaya yeWifi neXG, mutsauko wehunyanzvi pakati pavo wakafanana nekuzvimiririra kwedunhu uye centralization.Ivo vanotungamira kune zano rekuti mazhinji maWifi node akavakwa neakazvimirira (kana kambani, kana guta), nepo Vashandisi vachigadzira XG base zviteshi munyika.
Mune mamwe mazwi, mukufambiswa kwemasaini isina waya, nekuti marouters ega haatauri kune mumwe nemumwe uye anogovana zvakafanana spectrum, kuendesa data pamusoro peWifi kunokwikwidza.Kusiyana neizvi, kuendesa data pamusoro peXG hakusi kukwikwidza, kuri pakati pekugadzirisa zviwanikwa.
Zvishoma zvehunyanzvi, hatizoziva kana mharadzano inotevera ichingoerekana yaona mutsetse wakareba wemota dzine marambi matsvuku pamberi pedu patinenge tichityaira mumugwagwa.Chitima hachizove nerudzi urwu rwedambudziko;iyo central dispatch system inotumira zvese.
Privacy
Panguva imwecheteyo, Wifi yakabatana kune yakavanzika tambo Broadband.Iyo XG base station yakabatana neiyo backbone network yeOperators, saka Wifi kazhinji ine zvakavanzika zvinodiwa uye haigone kuwanikwa pasina mvumo.
Mobility
Nekuti Wifi yakabatana kune yakavanzika Broadband, iyo yemunhu tambo yekupinda nzvimbo yakagadziriswa, uye tambo ine waya.Izvi zvinoreva kuti wifi ine zvishoma kufamba kunodiwa uye diki yekuvhara nzvimbo.Zvinowanzodikanwa chete kufunga nezve maitiro ekumhanya kwekufamba pane chiratidzo chekufambisa, uye sero switching haina kutariswa.Nekudaro XG base station ine yakakwira kufamba uye sero switching zvinodiwa, uye zvinhu zvinomhanya-mhanya senge mota nezvitima zvinoda kutariswa.
Kwakadaro kukwikwidza / kusiri-kukwikwidza kuvanzika uye kufamba zvinodiwa zvinounza mutsauko wemisiyano kubva pabasa, tekinoroji uye kuvharika, kuwana, spectrum, kumhanya, nezvimwe.
Musiyano wehunyanzvi
1. Spectrum / Access
Spectrum pamwe ndiyo inonyanya kukonzera makwikwi.
Iyo frequency spectrum inoshandiswa newifi ndeye (2.4GHz/5G) iratidziro isina kunyoreswa, zvinoreva kuti haina kupihwa / kutengeserwa kune vanhu kana makambani, uye chero munhu / bhizinesi anogona kushandisa yavo wifi mudziyo kuiwana pamadiro.Iyo spectrum inoshandiswa neXG iratidziro ine rezinesi, uye hapana mumwe munhu ane kodzero yekushandisa iyi spectrum kunze kweVashandi vakawana huwandu.
Naizvozvo, paunobatidza wifi yako, uchaona runyoro rurefu rusina waya;mazhinji acho ari 2.4GHz routers.Izvi zvinoreva kuti iyi frequency bhendi yakawandisa, uye panogona kunge paine ruzha-sekupindira kwakawanda.
Izvi zvinoreva kuti kana mamwe matekinoroji akafanana, iyo Wifi SNR (chiratidzo kune ruzha chiyero) ichave yakaderera kune nharembozha pabhendi iri, izvo zvinozokonzera kudiki kuvharika kwewifi uye kutapurirana.Nekuda kweizvozvo, ikozvino wifi maprotocol ari kuwedzera kusvika ku5GHz, 60GHz uye mamwe mabhendi ekukanganisa akaderera.
Nerunyorwa rurefu rwakadai, uye frequency bhendi yewifi ishoma, pachave nemakwikwi ezviwanikwa zvechiteshi.Saka, iyo yakakosha air interface protocol ye wifi ndeye CSMA/CA (Mutakuri pfungwa kuwanda kuwana / kudhumhana kudzivirira).inoita izvi nekutarisa chiteshi isati yatumira uye kumirira nguva isina kujairika kana chiteshi chakabatikana.Asi iyo yekuona haisi nguva chaiyo, saka zvichiri kuitika kuti kune nzira mbiri pamwe chete kuti dzione iyo isina basa spectrum pamwe chete uye kutumira data panguva imwe chete.Ipapo dambudziko rekudhumhana rinoitika, uye nzira yekudzosera ichashandiswa kuendesa zvakare.
MuXG, nekuti nzira yekupinda yakagoverwa ne base station uye izvo zvinokanganisa zvinotariswa mugorogorithm, nzvimbo yekuvhara ye base station ine tekinoroji yakafanana ichave yakakura.Panguva imwecheteyo, mukufambiswa kwechiratidzo kare, XG yakagoverwa kune imwe nzvimbo yakatsaurirwa "mutsara", saka hapana chikonzero chekuonekwa kwechiteshi kusati kwatapukirwa, uye zvinodiwa zvekurovera kudzorera zvakare zvakanyanya.
Mumwe mutsauko wakakosha maererano nekuwana ndewekuti XG haina password nekuti maOperators anoda yakazara-saiti kuwana, uye vanoshandisa chitupa muSIM kadhi uye vanochaja nepagedhi rekubhadharisa.Private wifi kazhinji inoda password.
2.Coverage
Sezvambotaurwa, kufukidzwa kwewifi kunowanzo kuve kwakadzikira, mukuenzanisa, base station ichange iine chivharo chakakura nekuti simba rayo rekufambisa uye kukanganiswa kwebhendi.
Kumhanyisa kwenetiweki kunogona kukanganiswa nezvakawanda zvinhu, isu hatizokurukura kumhanya kwewifi neXG, kutaura zvazviri, kana zvinogoneka.
Asi muchivakwa chekambani, semuenzaniso, kana iwe uchida kuwedzera yako wifi yekuvhara kuti udimbure vashandi vako.A single wireless router zvirokwazvo haishande.Iyo imwechete isina waya router inovhara chivakwa chekambani inonyatso pfuura redhiyo rekufambisa simba rakatsanangurwa nenyika.Saka, mambure akabatanidzwa emagetsi akawanda anodiwa, semuenzaniso, router isina waya inotarisira imwe kamuri, asi mamwe ma routers anoshandisa zita rimwe chete uye anoshanda pamwe chete kuti aite network isina waya mukati meimba yese.
Isu tese tinoziva kuti imwe-node sarudzo-yekuita sarudzo ndiyo inonyanya kushanda system.ndiko kuti, kana paine multi-node kubatana mune isina waya network, iyo inonyanya kushanda nzira ndeyekuva netiweki-yakafara controller kubatsira yega yega router kuronga uye kugovera nguva / nzvimbo / spectrum zviwanikwa.
Mune wifi network (WLAN), iyo yakabatanidzwa AP (Access point) uye AC (Access Controller) murouter yepamba inoparadzaniswa.Iyo AC inodzora network uye inogovera zviwanikwa.
Zvakanaka, ko kana tikazviwedzera zvishoma.
Kusvika kunyika yese, imwe AC sezviri pachena haina kukwana data processing speed, ipapo dunhu rega rega rinoda AC yakafanana, uye imwe neimwe AC inodawo kushanda pamwechete kuti itaurirane.Izvi zvinogadzira iyo core network.
Uye imwe neimwe AP inoumba Radio Access Network.
Iyo nharembozha yekutaurirana network yeanoshanda inoumbwa nevarume iyo core network uye network yekuwana.
Sezvinoratidzwa pazasi, izvi zvakafanana newireless router network (WLAN)?
Kubva pane imwe chete router, kusvika kune akawanda-router padanho rekambani, kana kune base station coverage padanho renyika, uyu ungangove mutsauko uye kubatana pakati pewifi neXG.
