Chosangalatsa cha Wi-Fi 6 ndi Huawei

Tikukudziwitsani momwe Huawei amawonera pa Wi-Fi 6 - ukadaulo womwewo ndi zatsopano zofananira, makamaka zokhudzana ndi malo ofikira: zatsopano za iwo, komwe apeza kugwiritsa ntchito koyenera komanso kothandiza mu 2020, ndi njira ziti zaukadaulo zomwe zimawapatsa. ubwino waukulu wampikisano ndi momwe mzere wa AirEngine umapangidwira.

Zomwe zikuchitika muukadaulo wopanda zingwe masiku ano

M'zaka zomwe mibadwo yapitayi ya Wi-Fi - yachinayi ndi yachisanu - ikukula, lingaliro la ofesi yopanda zingwe, ndiko kuti, malo opanda zingwe opanda zingwe, adapangidwa mumakampani. Koma kuyambira nthawi imeneyo, madzi ambiri adutsa pansi pa mlatho, ndipo zofuna zamalonda zokhudzana ndi Wi-Fi zasintha bwino komanso mochuluka: zofunikira za bandwidth zawonjezeka, kuchepetsa latency kwakhala kovuta, ndipo kupitirira, kukakamiza kwambiri kulumikiza ambiri ogwiritsa ntchito.

Pofika chaka cha 2020, mawonekedwe atsopano adawonekera omwe ayenera kugwira ntchito modalirika pamanetiweki a Wi-Fi. Fanizoli likuwonetsa mbali zazikulu zomwe kugwiritsa ntchito kotereku kumakhudzana. Mwachidule za ochepa a iwo.

A. Augmented ndi zenizeni zenizeni. Kwa nthawi yayitali, mawu achidule a VR ndi AR adawonekera powonetsa ogulitsa ma telecom, koma ndi anthu ochepa omwe adamvetsetsa kuti kugwiritsa ntchito matekinoloje kumbuyo kwa zilembozi kunali chiyani. Masiku ano akulowa mwachangu m'miyoyo yathu, zomwe zikuwonetsedwa muzinthu za Huawei. Mu Epulo, tidayambitsa foni yam'manja ya Huawei P40 ndipo nthawi yomweyo idakhazikitsidwa - mpaka pano kokha ku China - ntchito ya Huawei Maps yokhala ndi ntchito ya AR Maps. Sikuti "GIS yokhala ndi ma hologram". Chowonadi chotsimikizika chimamangidwa mozama mu magwiridwe antchito: ndi chithandizo chake, sizimawononga chilichonse "kulanda" zambiri za bungwe linalake lomwe ofesi yake ili mnyumbamo, konzekerani njira kudutsa malo ozungulira - ndipo zonsezi mu 3D. mtundu komanso wapamwamba kwambiri.

AR iwonanso chitukuko champhamvu m'magawo a maphunziro ndi zaumoyo. Ndizofunikiranso kupanga: mwachitsanzo, kuti muphunzitse antchito momwe angachitire pakagwa mwadzidzidzi, ndizovuta kupeza china chabwinoko kuposa ma simulators muzowona zenizeni.

B. Machitidwe otetezera okhala ndi mavidiyo. Ndipo zokulirapo: yankho lililonse lakanema lomwe limakwaniritsa miyezo yapamwamba kwambiri. Sitikulankhula za 4K zokha, komanso za 8K. Otsogola opanga makanema apa TV ndi mapanelo azidziwitso amalonjeza kuti mitundu yopanga zithunzi za 8K UHD idzawoneka pazogulitsa zawo mu 2020. Ndizomveka kuganiza kuti ogwiritsa ntchito mapeto adzafunanso kuwonera makanema apamwamba kwambiri ndi bitrate yowonjezereka kwambiri.

B. Zoyimirira zabizinesi, ndipo choyamba chogulitsa. Tiyeni titenge chitsanzo Lidl - imodzi mwamaunyolo akulu kwambiri ku Europe. Amagwiritsa ntchito Wi-Fi yatsopano, zochokera ku IoT zochitika zolumikizana ndi ogula, makamaka, zidayambitsa ma tag amitengo yamagetsi a ESL, kuwaphatikiza ndi CRM yake.

Ponena za kupanga kwakukulu, zomwe zinachitikira Volkswagen ndizodabwitsa, zomwe zatumiza Wi-Fi kuchokera ku Huawei m'mafakitale ake ndikuzigwiritsa ntchito kuthetsa mavuto osiyanasiyana. Mwa zina, kampaniyo imadalira Wi-Fi 6 kuti igwiritse ntchito maloboti omwe amayenda mozungulira fakitale, kusanthula magawo munthawi yeniyeni pogwiritsa ntchito mawonekedwe a AR, ndi zina zambiri.

G. "Maofesi anzeru" imayimiranso malo akuluakulu opanga zinthu zatsopano pogwiritsa ntchito Wi-Fi 6. Chiwerengero chachikulu cha zochitika za intaneti za "nyumba yanzeru" zaganiziridwa kale, kuphatikizapo kulamulira chitetezo, kuyatsa magetsi, ndi zina zotero.

Sitiyenera kuiwala kuti mapulogalamu ambiri amasamukira kumtambo, ndipo kupeza mtambo kumafuna kugwirizana kwapamwamba, kokhazikika. Ichi ndichifukwa chake Huawei amagwiritsa ntchito mawuwa ndikuyesetsa kukwaniritsa cholinga cha "100 Mbps kulikonse": Wi-Fi ikukhala njira yayikulu yolumikizirana ndi intaneti, ndipo mosasamala kanthu komwe wogwiritsa ntchito ali, timakakamizika kumupatsa mwayi wapamwamba kwambiri. mulingo wogwiritsa ntchito.

Momwe Huawei akufunira kuyang'anira chilengedwe chanu cha Wi-Fi 6

Pakadali pano, Huawei akulimbikitsa njira yokonzekera yomaliza-yomaliza ya Cloud Campus, yomwe cholinga chake, kumbali imodzi, kuthandiza kuyang'anira zomangamanga zonse kuchokera mumtambo, komanso kumbali ina, kukhala ngati nsanja yoyendetsera zatsopano. Zochitika za IoT, zikhale kasamalidwe ka nyumba, kuyang'anira zida kapena, mwachitsanzo, ngati titembenukira ku nkhani kuchokera kumunda wamankhwala, kuyang'anira magawo ofunikira a wodwalayo.

Gawo lofunikira pazachilengedwe kuzungulira Cloud Campus ndi msika. Mwachitsanzo, ngati wopanga mapulogalamu apanga chipangizo chomaliza ndikuchiphatikiza ndi mayankho a Huawei polemba pulogalamu yoyenera, ali ndi ufulu wopereka mankhwala ake kwa makasitomala athu ena pogwiritsa ntchito chitsanzo cha utumiki.

Popeza maukonde a Wi-Fi amakhala maziko oyendetsera bizinesi, njira zakale zowongolera sizokwanira. M'mbuyomu, woyang'anira adakakamizika kudziwa zomwe zikuchitika ndi maukonde pafupifupi pamanja, kukumba zipika. Njira yothandizirayi ndiyosowa tsopano. Zida ndizofunikira pakuwunikira komanso kuyang'anira magwiridwe antchito opanda zingwe kuti woyang'anira amvetsetse zomwe zikuchitika kwa izo: kuchuluka kwa zomwe ogwiritsa ntchito amapereka, kaya ogwiritsa ntchito atsopano atha kulumikizana nazo popanda zovuta, kaya kasitomala aliyense ayenera kukhala. "Kusamutsidwa" kumalo ofikira oyandikana nawo (AP), komwe node iliyonse ya netiweki ili mkati, ndi zina.

Pazida za Wi-Fi 6, Huawei ali ndi zida zonse zowunikira, kusanthula mozama ndikuwongolera zomwe zikuchitika pa intaneti. Zochitika izi zimakhazikika pamakina ophunzirira makina.

Izi sizinali zotheka pa malo olowera mndandanda wapitawo, popeza sanagwirizane ndi ndondomeko zoyenera za telemetry, ndipo kawirikawiri machitidwe a zipangizozi sanalole kuti ntchitoyi ichitike mu mawonekedwe omwe malo athu amakono amalola.

Kodi ubwino wa Wi-Fi 6 standard ndi chiyani

Kwa nthawi yayitali, chopunthwitsa kufalikira kwa Wi-Fi 6 idakhalabe mfundo yakuti panalibe zida zopanda malire zomwe zimathandizira muyezo wa IEEE 802.11ax ndipo zimatha kuzindikira bwino zabwino zomwe zimapezeka pamalowo. Komabe, kusintha kukuchitika mumakampani, ndipo ife, monga wogulitsa, tikuthandizira ndi mphamvu zathu zonse: Huawei wapanga ma chipsets ake osati pazinthu zamakampani, komanso zida zam'manja ndi zapanyumba.

- Zambiri za Wi-Fi 6+ zochokera ku Huawei zikufalikira pa intaneti. Ichi ndi chiyani?
- Zili ngati Wi-Fi 6E. Chilichonse ndi chofanana, ndikungowonjezera ma frequency a 6 GHz. Mayiko ambiri pakali pano akuganiza zopangitsa kuti ipezeke pa Wi-Fi 6.

- Kodi mawonekedwe a wailesi ya 6 GHz adzakhazikitsidwa pagawo lomwelo lomwe likugwira ntchito pa 5 GHz?
- Ayi, padzakhala tinyanga zapadera zogwirira ntchito mu 6 GHz frequency range. Malo opezeka pano sathandizira 6 GHz, ngakhale mapulogalamu awo asinthidwa.

Masiku ano, zida zomwe zikuwonetsedwa m'chifanizozi ndi za gawo lapamwamba. Nthawi yomweyo, Huawei AX3 rauta yakunyumba, yomwe imapereka liwiro la 2 Gbit / s kudzera panjira zolumikizira mpweya, sizosiyana ndi mtengo kuchokera kumalo ofikira m'badwo wakale. Chifukwa chake, pali zifukwa zomveka zokhulupirira kuti mu 2020, zida zambiri zapakatikati komanso ngakhale zolowera zilandila chithandizo cha Wi-Fi 6. Malinga ndi mawerengedwe a Huawei, pofika chaka cha 2022, malonda a malo olowera pa Wi-Fi 6 poyerekeza ndi omwe adamangidwa pa Wi-Fi 5 adzakhala 90 mpaka 10%.

Mu chaka ndi theka, nthawi ya Wi-Fi 6 ifika.

Choyamba, Wi-Fi 6 idapangidwa kuti ipangitse ma netiweki opanda zingwe kukhala abwino. M'mbuyomu, siteshoni iliyonse inkapatsidwa nthawi yotsatizana ndipo inkatenga njira yonse ya 20 MHz, kukakamiza ena kuti adikire kuti atumize magalimoto. Tsopano ma 20 MHz awa amadulidwa kukhala ma subcarriers ang'onoang'ono, ophatikizidwa kukhala zida zothandizira, mpaka 2 MHz, ndipo mpaka masiteshoni asanu ndi anayi amatha kuwulutsa nthawi imodzi. Izi zimabweretsa kuwonjezeka kwakukulu kwa machitidwe a intaneti yonse.

Tanena kale kuti machitidwe apamwamba osinthika adawonjezeredwa ku mibadwo yachisanu ndi chimodzi: 1024-QAM motsutsana ndi 256 yapitayi. 25 bits.

Chiwerengero cha mitsinje ya malo chawonjezekanso. M'miyezo yam'mbuyomu panali anayi, pomwe pano alipo asanu ndi atatu, ndipo akale a Huawei amafikira mpaka khumi ndi awiri.

Kuphatikiza apo, Wi-Fi 6 imagwiritsanso ntchito ma frequency a 2,4 GHz, zomwe zimapangitsa kuti zitheke kupanga ma chipset otsika mtengo opangira ma terminal omwe amathandizira Wi-Fi 6 ndikulumikiza zida zambiri, zikhale ma module a IoT kapena zina zambiri. zotsika mtengo masensa

Chofunikira kwambiri ndichakuti mulingowu umagwiritsa ntchito matekinoloje ambiri kuti agwiritse ntchito bwino ma wailesi, kuphatikiza kugwiritsa ntchitonso ma tchanelo ndi ma frequency. Choyamba, mitundu ya Basic Service Set (BSS) ndiyoyenera kutchulidwa, yomwe imakulolani kunyalanyaza malo omwe anthu ena akugwiritsa ntchito pa njira yomweyo, ndipo nthawi yomweyo "mverani" zanu.

Ndi malo ati a Wi-Fi 6 ochokera ku Huawei omwe tikuganiza kuti akuyenera kuchitidwa poyamba?

Zithunzizi zikuwonetsa malo omwe Huawei amapereka lero ndipo, chofunika kwambiri, zomwe zidzayamba kupereka posachedwa, kuyambira ndi chitsanzo choyambirira cha AirEngine 5760 ndikutha ndi apamwamba.

Malo athu ofikira omwe amathandizira mulingo wa 802.11ax amakhazikitsa mayankho osiyanasiyana apadera aukadaulo.

• Kupezeka kwa module yomangidwa mu IoT kapena kutha kulumikiza yakunja. Pamalo onse olowera, chivundikiro chapamwamba tsopano chikutsegulidwa, ndipo pansi pake pali mipata iwiri ya ma module a IoT, pafupifupi mtundu uliwonse. Mwachitsanzo, kuchokera ku ZigBee, yoyenera kulumikiza ma socket anzeru kapena ma relay, masensa a telemetry, ndi zina zotero. Hansow). Kuphatikiza apo, malo ena ofikira angapo amakhala ndi cholumikizira chowonjezera cha USB, ndipo gawo la intaneti la Zinthu limatha kulumikizidwa kudzera pamenepo.
• Mbadwo watsopano waukadaulo wa Smart Antenna. Malo okhalamo amakhala ndi tinyanga 16, zomwe zimapanga mitsinje yofikira 12. "Nnyanga zanzeru" zotere zimapangitsa kuti zikhale zotheka, makamaka, kukulitsa utali wozungulira (ndi kuchotsa "zigawo zakufa") chifukwa chakuti aliyense wa iwo ali ndi mitundu ingapo ya kufalikira kwa ma wayilesi ndi "kumvetsetsa" komwe kuli kofunikira. malo malo lili nthawi imodzi kapena kasitomala wina.
• Mawonekedwe okulirapo amakanema zikutanthauza kuti RSSI ya kasitomala, kapena mlingo wa chizindikiro cholandirira, udzakhalanso wapamwamba. M'mayesero ofananiza, pomwe malo ofikira amni-directional nthawi zonse ndi imodzi yokhala ndi tinyanga tanzeru imayesedwa, yachiwiri imakhala ndi mphamvu zowonjezera kawiri - 3 dB yowonjezera.

Mukamagwiritsa ntchito tinyanga tanzeru, palibe chizindikiro cha asymmetry, chifukwa kukhudzika kwa malo ofikira kumawonjezeka molingana. Chilichonse mwa tinyanga 16 chimakhala ngati kalilole: chifukwa cha mfundo ya kufalitsa kwachulukidwe, kasitomala akatumiza mtengo wazidziwitso, mawayilesi ofananirako, omwe amawonekera kuchokera ku zopinga zosiyanasiyana, amamenya tinyanga zonse 16. Kenako mfundoyo, pogwiritsa ntchito ma aligorivimu ake amkati, imawonjezera zizindikiro zomwe zalandilidwa ndikubwezeretsanso deta yosungidwa ndi kudalirika kwakukulu.

• Malo onse atsopano a Huawei akugwiritsa ntchito ukadaulo wa SDR (Software-Defined Radio). Chifukwa cha izi, kutengera zomwe amakonda kugwiritsa ntchito zida zopanda zingwe, woyang'anira amasankha momwe ma module atatuwa amagwirira ntchito. Ndi mitsinje ingati yapadziko lapansi yomwe ingagawidwe kwa wina ndi mnzake imatsimikiziridwanso mwamphamvu. Mwachitsanzo, mutha kupanga ma module awiri a wailesi kuti agwirizane ndi makasitomala (imodzi mu 2,4 GHz, ina mu 5 GHz), ndipo yachitatu imagwira ntchito ngati scanner, kuyang'anira zomwe zikuchitika ndi chilengedwe cha wailesi. Kapena gwiritsani ntchito ma module atatu kuti mulumikizane ndi makasitomala.

  Chinthu china chodziwika bwino ndi pamene palibe makasitomala ambiri pa intaneti, koma zipangizo zawo zimayendetsa ntchito zolemetsa kwambiri zomwe zimafuna bandwidth yapamwamba. Pachifukwa ichi, mitsinje yonse ya malo imamangiriridwa ku maulendo afupipafupi a 2,4 ndi 5 GHz, ndipo mayendedwe amaphatikizidwa kuti apatse ogwiritsa ntchito osati 20, koma 80 MHz bandwidth.

• Malo olowera akugwira ntchito zosefera malinga ndi 3GPP specifications, kuti mulekanitse ma module a wailesi omwe amatha kugwira ntchito pama frequency osiyanasiyana mumtundu wa 5 GHz wina ndi mnzake, kuti mupewe kusokoneza mkati.

Malo olowera amapereka ntchito m'njira zosiyanasiyana. Chimodzi mwa izo ndi RTU (Ufulu-Kugwiritsa). Mwachidule, mfundo yake yaikulu ndi iyi. Mitundu yamitundu ingapo idzaperekedwa mu mtundu wokhazikika, mwachitsanzo ndi mitsinje isanu ndi umodzi. Kupitilira apo, mothandizidwa ndi chilolezo, zitha kukulitsa magwiridwe antchito a chipangizocho ndikuyambitsa mitsinje ina iwiri, kuwulula kuthekera kwa Hardware komwe kumakhalamo. Njira ina: mwina, pakapita nthawi, kasitomala adzafunika kuyika mawonekedwe owonjezera a wailesi kuti ayang'ane ma airwaves, ndipo kuti ayambe kugwira ntchito, zidzakhala zokwanira kugula laisensi kachiwiri.

Pansi kumanja kwa fanizo lapitalo, malo ofikira ali ndi makalata a digito, mwachitsanzo 2 + 2 + 4 pokhudzana ndi AirEngine 5760. Mfundo ndi yakuti AP ili ndi ma modules atatu odziimira okha.

Njira yowerengera ikuwonetsedwa pachithunzi pamwambapa. Tiyeni tiwone zomwe ochulutsa momwemo ndi.

Yoyamba ndi chiwerengero cha mitsinje yapakatikati (pa 2,4 GHz - mpaka inayi, pa 5 GHz - mpaka eyiti). Chachiwiri ndi gawo logawidwa ndi kuchuluka kwa nthawi ya chizindikiro komanso nthawi yachitetezo molingana ndi muyezo womwe wagwiritsidwa ntchito. Popeza mu Wi-Fi 6 nthawi ya chizindikiro imawirikiza kanayi mpaka 12,8 μs, ndipo nthawi ya alonda ndi 0,8 μs, zotsatira zake ndi 1/13,6 μs.

Chotsatira: monga chikumbutso, chifukwa chakusintha kwa 1024-QAM, mpaka ma bits 10 tsopano atha kusindikizidwa pachizindikiro chilichonse. Pazonse, tili ndi bitrate ya 5/6 (FEC) - chochulukitsa chachinayi. Ndipo chachisanu ndi chiwerengero cha subcarriers (matoni).

Pomaliza, kuwonjezera magwiridwe antchito apamwamba a 2,4 ndi 5 GHz, timapeza mtengo wochititsa chidwi wa 10,75 Gbps.

DBS radio frequency resource management yawonekeranso m'malo athu ofikira ndi owongolera. Ngati m'mbuyomu mumayenera kusankha m'lifupi mwa njira ya SSID inayake kamodzi (20, 40 kapena 80 MHz), tsopano ndizotheka kukonza wowongolera kuti azichita izi mwamphamvu.

Ukadaulo wa SmartRadio wabweretsa kusintha kwina pakugawa zinthu zamawayilesi. M'mbuyomu, ngati panali malo angapo olowera m'dera limodzi, zinali zotheka kufotokozera ndi zomwe aligorivimu kuti agawirenso makasitomala, pomwe AP ilumikizane yatsopano, etc. kulumikizana ndi netiweki ya Wi-Fi. Pankhani ya AirEngine, ma aligorivimu owongolera katundu amatha kugwiritsidwa ntchito munthawi yeniyeni pomwe makasitomala akugwira ntchito ndipo, mwachitsanzo, kusuntha pakati pa malo ofikira.

Chofunikira chokhudza zinthu za mlongoti: mumitundu ya AirEngine nthawi imodzi amagwiritsa ntchito polarization yoyima komanso yopingasa. Iliyonse imakhala ndi tinyanga zinayi, ndipo pali zinthu zinayi zotere. Choncho chiwerengero chonse - 16 tinyanga.

Chinthu cha antenna palokha sichimangokhala. Chifukwa chake, kuti muzitha kuyang'ana mphamvu zambiri molunjika kwa kasitomala, ndikofunikira kupanga mtengo wocheperako pogwiritsa ntchito tinyanga tating'ono. Huawei adachita bwino. Zotsatira zake ndi kuwulutsa pawayilesi pa avareji 20% kuposa mayankho opikisana.

Ndi Wi-Fi 6, ultra-high throughput and high modulation levels (MCS 10 ndi MCS 11 schemes) ndizotheka pokhapokha chiŵerengero cha signal-to-noise, kapena Signal-to-Noise Ratio, chikuposa 35 dB. Decibel iliyonse imawerengera. Ndipo mlongoti wanzeru umakulolani kuti muwonjezere mlingo wa chizindikiro chomwe mwalandira.

M'mayesero enieni, kusinthika kwa 1024-QAM ndi MCS 10 chiwembu kudzagwira ntchito mtunda wosapitilira 3 m kuchokera pamalo ofikira, aliwonse omwe akupezeka pamsika. Chabwino, mukamagwiritsa ntchito mlongoti "wanzeru", mtunda ukhoza kuwonjezeka mpaka 6-7 m.

Tekinoloje ina yomwe Huawei waphatikiza ndi malo atsopano olowera imatchedwa Dynamic Turbo. Cholinga chake ndi chakuti AP imatha kuzindikira ndikuyika mapulogalamu pa ntchentche ndi kalasi (mwachitsanzo, imatumiza kanema wanthawi yeniyeni, kuchuluka kwa mawu kapena china chake), kusiyanitsa makasitomala malinga ndi kufunikira kwawo ndikugawa magawo othandizira njira yotereyi kuti muwonetsetse kuti ntchito zapamwamba zomwe zili zofunika kwa ogwiritsa ntchito zimathamanga mofulumira momwe zingathere. M'malo mwake, pamlingo wa Hardware, malo ofikira amachita DPI - kusanthula kwakuzama kwa magalimoto.

Monga tanena kale, Huawei ndiye yekha wogulitsa yemwe amapereka ntchito imodzi ya MU-MIMO ndi OFDMA pamayankho ake. Tiyeni titenge tsatanetsatane pang'ono za kusiyana pakati pawo.

Matekinoloje onsewa adapangidwa kuti azipereka mwayi kwa ogwiritsa ntchito ambiri. Pakakhala ogwiritsa ntchito ambiri pamanetiweki, OFDMA imalola kuti pafupipafupi gwero ligawidwe kuti makasitomala ambiri alandire ndikulandila zambiri nthawi imodzi. Komabe, MU-MIMO pamapeto pake imayang'ana chinthu chomwecho: makasitomala angapo akapezeka m'malo osiyanasiyana mchipindacho, aliyense amatha kutumizidwa mtsinje wapadera wamalo. Kuti timveke bwino, tiyeni tiyerekeze kuti gwero lafupipafupi ndilo njira ya Moscow-St. OFDMA ikuwoneka kuti ikupereka lingaliro lakuti: “Tiyeni tipange msewuwo osati msewu umodzi, koma uŵiri, kuti ugwiritsidwe ntchito bwino kwambiri.” MU-MIMO ili ndi njira yosiyana: "Tiyeni tipange msewu wachiwiri, wachitatu kuti magalimoto aziyenda modziyimira pawokha." Mwachidziwitso, chimodzi sichitsutsana ndi chimzake, koma zenizeni, kuphatikiza kwa njira ziwiri kumafuna maziko a algorithmic. Chifukwa chakuti Huawei adatha kupanga maziko awa, kutulutsa kwa malo athu ofikirako kwawonjezeka pafupifupi 40% poyerekeza ndi zomwe opikisana nawo amatha kupereka.

Ponena za chitetezo, malo atsopano olowera, monga zitsanzo zam'mbuyomu, amathandizira DTLS. Izi zikutanthauza, monga kale, CAPWAP control traffic itha kubisidwa.

Ndi chitetezo ku zisonkhezero zoipa zakunja, chirichonse chiri chofanana ndi mbadwo wakale wa olamulira. Kuwukira kwamtundu uliwonse, kaya ndi mphamvu yankhanza, kuukira kofooka kwa IV (ma vector oyambira ofooka) kapena china chake, kumadziwika munthawi yeniyeni. Zomwe zimachitika ku DDoS zimathanso kusinthika: dongosololi limatha kupanga mindandanda yakuda, dziwitsani woyang'anira zomwe zikuchitika poyesa kugawa maukonde, ndi zina zambiri.

Ndi mayankho ati omwe amatsagana ndi mitundu ya AirEngine

Pulogalamu yathu yowunikira ya CampusInsight Wi-Fi 6 imathetsa mavuto angapo. Choyamba, imagwiritsidwa ntchito pakuwongolera wailesi limodzi ndi wowongolera: CampusInsight imakupatsani mwayi wowongolera komanso kugawa bwino ma tchanelo munthawi yeniyeni, kusintha mphamvu ya siginecha ndi bandwidth ya njira inayake, ndikuwongolera zomwe zikuchitika ndi Wi-Fi. network. Ndi zonsezi, CampusInsight imagwiranso ntchito pachitetezo chopanda zingwe (makamaka, popewa kulowerera ndi kuzindikira), osati pokhudzana ndi malo enaake olowera kapena SSID imodzi, koma pamlingo wazinthu zonse zopanda zingwe.

WLAN Planner ndiyofunikanso kuyang'ana - chida chowonetsera wailesi, ndipo imatha kudziwa zopinga zina, monga makoma. Pazotulutsa, pulogalamuyo imapanga lipoti lalifupi, lomwe, mwa zina, limasonyeza kuti ndi zingati zomwe zimafunikira kuti zitheke kuphimba chipindacho. Kutengera zomwe zaperekedwa, ndizosavuta kupanga zisankho zodziwitsidwa bwino za zida, kukonza bajeti, ndi zina zambiri.

Pakati pa mapulogalamuwa, timatchulanso Cloud Campus App, yomwe imapezeka kwa aliyense pa iOS ndi Android ndipo ili ndi zida zonse zowunikira maukonde opanda zingwe. Zina mwazo zidapangidwa kuti ziziyesa mtundu wa Wi-Fi (mwachitsanzo, kuyesa koyendayenda). Mwa zina, mukhoza kuyesa mlingo wa chizindikiro, kupeza magwero a zosokoneza, kuyang'ana zomwe zikuchitika m'dera linalake, ndipo ngati pali mavuto, dziwani zomwe zimayambitsa.
