Kwenikweni, kufananitsa pakati pa 5G ndi WiFi sikoyenera.Chifukwa 5G ndi "m'badwo wachisanu" wamakina olumikizirana ndi mafoni, ndipo WiFi imaphatikizanso mitundu yambiri ya "mibadwo" monga 802.11/a/b/g/n/ac/ad/ax, ndizofanana ndi kusiyana pakati pa Tesla ndi Sitimayi. .

Mokulirapo, kuchokera pamlingo womwewo, kusiyana pakati pa njira yolumikizirana yam'manja (XG, X=1,2,3,4,5) ndi Wifi yomwe timagwiritsa ntchito masiku ano?
Kusiyana pakati pa XG ndi Wifi
Monga wogwiritsa ntchito, zomwe ndakumana nazo ndikuti Wifi ndiyotsika mtengo kwambiri kuposa XG, ndipo ngati tinyalanyaza mtengo wa mawilo amtundu wa waya ndi ma routers, titha kuganiza kuti kugwiritsa ntchito wifi kulumikiza pa intaneti ndi kwaulere.Komabe, nthawi zambiri, mitengo imatha kuwonetsa zinthu zina zaukadaulo.Ngati mutenga netiweki yaying'ono ndikuyikulitsa kudziko lonse lapansi komanso kumayiko ena, ndi XG.Koma pali kusiyana kwakukulu pakati pa zazikulu ndi zazing'ono.
Kuti tifotokoze kusiyana pakati pawo, tiyenera kuyamba ndi zofunika.
Kusiyana kwa zofuna
Wopikisana
Pankhani ya Wifi ndi XG, kusiyana kwaukadaulo pakati pawo kuli kofanana ndi kudziyimira pawokha kwachigawo ndi centralization.Amatsogolera ku lingaliro loti ma Wifi node ambiri amamangidwa ndi payekha (kapena kampani, kapena mzinda), pomwe Othandizira amapanga masiteshoni a XG mdziko muno.
Mwanjira ina, potumiza ma siginecha opanda zingwe, chifukwa ma routers pawokha samalumikizana wina ndi mnzake ndikugawana mawonekedwe omwewo, kutumiza kwa data pa Wifi ndikopikisana.Mosiyana ndi izi, kutumizirana ma data pa XG sikuli mpikisano, ndikukonza zida zapakati.
Zocheperako mwaukadaulo, sitingadziwe ngati mphambano yotsatira idzawona mwadzidzidzi mzere wautali wa magalimoto okhala ndi nyali zofiira kutsogolo kwathu tikamatuluka mumsewu.Njanjiyo sidzakhala ndi vuto lotere;central dispatch system imatumiza chilichonse.
Zazinsinsi
Nthawi yomweyo, Wifi imalumikizidwa ndi bandi yachinsinsi.XG base station imalumikizidwa ndi netiweki yam'mbuyo ya Operators, kotero Wifi nthawi zambiri imakhala ndi zofunikira zachinsinsi ndipo sangathe kupezeka popanda chilolezo.
Kuyenda
Chifukwa Wifi ndi yolumikizidwa ku burodibandi yachinsinsi, malo olowera chingwe amakhala okhazikika, ndipo chingwecho chimakhala ndi mawaya.Izi zikutanthauza kuti wifi ili ndi mayendedwe ochepa komanso malo ocheperako.Nthawi zambiri zimangofunika kuganizira momwe liwiro la kuyenda limakhudzira potumiza ma siginecha, ndipo kusintha kwa ma cell sikuganiziridwa.Komabe malo oyambira a XG ali ndi mayendedwe apamwamba komanso zofunikira zosinthira ma cell, ndipo zinthu zothamanga kwambiri monga magalimoto ndi masitima apamtunda ziyenera kuganiziridwa.
Zofunikira zachinsinsi zopikisana / zopanda mpikisano komanso zoyenda zidzabweretsa kusiyana kosiyanasiyana kuchokera ku ntchito, ukadaulo ndi kuphimba, mwayi, mawonekedwe, liwiro, ndi zina zambiri.
Kusiyana kwaukadaulo
1. Spectrum / Access
Spectrum mwina ndiye choyambitsa mpikisano mwachangu.
Ma frequency spectrum omwe amagwiritsidwa ntchito ndi wifi ndi (2.4GHz/5G) ndi mawonekedwe osavomerezeka, zomwe zikutanthauza kuti sanagawidwe / kugulitsidwa kwa anthu kapena makampani, ndipo aliyense/bizinesi atha kugwiritsa ntchito chida chawo cha wifi kuti apeze momwe angafune.Sipekitiramu yogwiritsidwa ntchito ndi XG ndi sipekitiramu yovomerezeka, ndipo palibe amene ali ndi ufulu wogwiritsa ntchito sipekitiramuyi kupatula Ogwiritsa ntchito omwe apeza mitundu.
Chifukwa chake, mukayatsa wifi yanu, mudzawona mndandanda wautali kwambiri wopanda zingwe;ambiri aiwo ndi 2.4GHz routers.Izi zikutanthawuza kuti gulu lafupipafupili ndi lodzaza kwambiri, ndipo pangakhale phokoso lalikulu ngati kusokoneza.
Izi zikutanthauza kuti ngati matekinoloje ena onse ali ofanana, Wifi SNR (chiŵerengero cha chizindikiro cha phokoso) idzakhala yotsika kwa mafoni a m'manja pa gulu ili, zomwe zidzachititsa kuti pakhale kufalikira kwa wifi ndi kutumiza.Zotsatira zake, ma protocol apano a wifi akukulira mpaka 5GHz, 60GHz ndi magulu ena otsika osokoneza pafupipafupi.
Ndi mndandanda wautali wotere, ndipo gulu lafupipafupi la wifi ndilochepa, padzakhala mpikisano wazinthu zamakina.Chifukwa chake, njira yayikulu yolumikizira mpweya ya wifi ndi CSMA/CA (Carrier sense multiple access/kupewa kugunda).imachita izi poyang'ana tchanelo musanatumize ndikudikirira kwanthawi yochepa ngati tchanelo chili chotanganidwa.Koma kuzindikira si nthawi yeniyeni, kotero n'zothekabe kuti pali njira ziwiri palimodzi kuti zizindikire zosagwira ntchito pamodzi ndi kutumiza deta nthawi imodzi.Kenako vuto la kugunda limachitika, ndipo njira yotumiziranso idzagwiritsidwa ntchito kutumizanso.
Mu XG, chifukwa njira yolowera imaperekedwa ndi malo oyambira ndipo zinthu zosokoneza zimaganiziridwa mu algorithm yogawa, malo ofikira malo oyambira ndiukadaulo womwewo adzakhala okulirapo.Panthawi imodzimodziyo, potumiza chizindikiro chisanachitike, XG yaperekedwa ku "mzere" wodzipatulira woyambira, kotero palibe chifukwa chodziwira njira musanayambe kupatsirana, ndipo zofunikira za kugundananso ndizochepa kwambiri.
Kusiyana kwina kwakukulu pankhani yofikira ndikuti XG ilibe mawu achinsinsi chifukwa Ogwiritsa ntchito amafunikira malo onse, ndipo amagwiritsa ntchito chizindikiritso cha SIM khadi ndikulipiritsa kudzera pachipata cholipira.Wifi yachinsinsi nthawi zambiri imafuna mawu achinsinsi.
2.Kufotokozera
Monga tanena kale, kufalikira kwa wifi nthawi zambiri kumakhala kotsika, poyerekeza, malo oyambira amakhala ndi njira yokulirapo chifukwa mphamvu zake zotumizirana zambiri komanso kusokoneza kwa band pafupipafupi.
Kuthamanga kwa intaneti kungakhudzidwe ndi zinthu zambiri, sitidzakambirana za liwiro la wifi ndi XG, kwenikweni, mwina ndizotheka.
Koma m'nyumba yamakampani, mwachitsanzo, ngati mukufuna kuwonjezera kufalikira kwa wifi kuti muchotse antchito anu.Router imodzi yopanda zingwe sigwira ntchito.Rauta imodzi yopanda zingwe yomwe ikuphimba nyumba ya kampaniyo ipitilira mphamvu yotumizira mawayilesi yomwe dzikolo likunena.Choncho, makina ophatikizana a ma routers ambiri amafunikira, mwachitsanzo, router yopanda zingwe imayang'anira chipinda chimodzi, pamene ma routers ena amagwiritsa ntchito dzina lomwelo ndikugwira ntchito limodzi kuti apange makina opanda zingwe m'nyumba yonse.
Tonse tikudziwa kuti njira yopangira zisankho za node imodzi ndiyo njira yabwino kwambiri.ndiko kuti, ngati pali mgwirizano wamagulu ambiri mu intaneti yopanda zingwe, njira yabwino kwambiri ndiyo kukhala ndi wolamulira wapaintaneti kuti athandize ndondomeko iliyonse ya rauta ndikugawa nthawi / malo / masewero.
Mu netiweki ya wifi (WLAN), AP (Access point) ndi AC (Access Controller) mu rauta yakunyumba zimasiyanitsidwa.AC imayendetsa maukonde ndikugawa zothandizira.
Chabwino, bwanji ngati tikulitsa pang'ono.
Kufikira dziko lonse lapansi, AC imodzi mwachiwonekere sikokwanira kuthamanga kwa data, ndiye kuti dera lililonse likufunika AC yofanana, ndipo AC iliyonse iyeneranso kugwirira ntchito limodzi kuti ilankhulane.Izi zimapanga core network.
Ndipo AP iliyonse imapanga Radio Access Network.
Netiweki yolumikizirana yam'manja ya woyendetsayo imapangidwa ndi ma netiweki oyambira ndi netiweki yofikira.
Monga momwe zilili pansipa, kodi izi zikufanana ndi netiweki yopanda zingwe (WLAN)?
Kuchokera pa rauta imodzi, kupita ku ma rauta angapo pamlingo wamakampani, kapena kufalitsa masiteshoni pamtunda wadziko lonse, izi mwina ndiye kusiyana ndi kulumikizana pakati pa wifi ndi XG.
