- Kutenderera uye kutungamira nebhendi
Kufamba-famba zvakanaka kunoita kuti vashandisi vasasiye kana vachichinja nzvimbo. Kutungamira kwebhendi kunokurudzira zvishandiso zvinoenderana kuti zvishandise mabhendi e5 GHz/6 GHz, ayo anowanzova akakura kupfuura 2,4 GHz.
4. Kutarisa uye Kugadzirisa Matambudziko
Kutarisira network hakumire mushure mekuitwa kwayo. Kutarisa kunodiwa kuti uone matambudziko asati apararira. Zvinhu zvakakosha zvekutarisa zvinosanganisira:
- Simba rechiratidzo (RSSI) uye mhando yechiratidzo (SNR)
RSSI inoratidza simba remasaini, ukuwo SNR ichiratidza chiyero chesignal-to-noise. Matambudziko ekubatanidza anogona kuitika kunyangwe paine RSSI yakanaka kana ruzha rwakakwira.
- Kuburikidza, kunonoka, uye kurasikirwa kwepaketi
Mapurogiramu epanguva chaiyo akadai seVoIP nemavhidhiyo anonyanya kukanganiswa nekunonoka uye kurasikirwa.
- Huwandu hwevatengi paAP imwe neimwe
MaAP akawandisa anoderedza mashandiro. Mhinduro dzinosanganisira kuwedzera maAP, kugadzirisa simba, kana kuenzanisa mutoro.
- Kupindirana uye kushandiswa kwenzira
Zvishandiso zvekuongorora zveSpectrum kana maficha ekuongorora pamidziyo yebhizinesi anogona kuona kukanganiswa kusiri kweWi-Fi.
Kugadzirisa matambudziko kunowanzoitwa nenzira yedanho nedanho: tarisa kana dambudziko riri pamutengi, AP, network yemagetsi (uplink), authentication service (RADIUS), kana internet connection. Magwaro uye mashandiro anobatsira kukurumidzisa kuongororwa kwedambudziko.
5. Kuchengetedzwa kweNetwork isina waya
Kuchengetedzeka chinhu chakakosha pakutarisira network isina waya, nekuda kwekuvhurika kwenzira yekutumira mashoko. Maitiro akajairika anosanganisira:
- Shandisa WPA3 kana kuti WPA2-Enterprise
WPA2/WPA3-Enterprise ine 802.1X uye RADIUS inopa humbowo hwekuti inoshanda sei pamunhu wega wega, zvichiita kuti ive yakakodzera masangano. Kune veruzhinji, portal inogona kushandiswa, asi dziviriro yekuwedzera ichiri kudiwa.
- Kupatsanurwa kwenetiweki (VLAN/SSID yakasiyana)
Manetwork emidziyo yevashandi, vaenzi, uye yeIoT akasiyana. IoT inowanzova isina kuchengetedzeka kwakasimba, saka kupinda kwayo kunofanira kudziviswa.
- Nzira dzekupinda uye firewall
Shandisa pfungwa yekuti hapana mukana wekushandisa: vashandisi vane mukana wekuwana zvavanoda chete. Shandisa maACL, mafirewall, kana micro-segmentation kana zviripo.
- Zvigadziriso zveFirmware uye maPatches
MaAP nevanodzora vanoda nguva nenguva kuti vadzivise matambudziko ekuchengetedza. Vatungamiriri vakanaka vane purogiramu yekuchengetedza uye nzira dzekudzosera zvinhu kumashure.
- Tsvaga AP ine hutsinye uye kurwiswa
Masisitimu eWireless Intrusion Detection/Prevention (WIDS/WIPS) anobatsira kuona nzvimbo dzekupinda dzisina kurongeka kana kuedza kunyengedza.
6. Kutarisira QoS uye Ruzivo rweMushandisi
Hunhu Hwebasa (QoS) hunoita kuti mapurogiramu akakosha apihwe mukana wekutanga. Semuenzaniso, vanhu vanoteerera manzwi nemavhidhiyo vanopihwa mukana wekutanga kupfuura vanhu vakawanda vanodhawunirodha. PaWi-Fi, QoS inogona kushandisa WMM (Wi-Fi Multimedia). Uyezve, manejimendi emazuva ano anowanzo tarisa paHunhu Hwechiitiko (QoE): kwete chete hunyanzvi hwekuongorora, asi kana vashandisi vachiona kubatana kwacho se "kunokurumidza uye kwakagadzikana."
Mamwe matanho anoshanda anosanganisira kurambidzwa kwebandwidth kune network dzevashanyi, kurambidzwa kwemitengo kune mamwe maapplication, uye mitemo yekushandiswa kwakaringana kana network yazara.
7. Kuzvigadzira otomatiki uye Kutarisira Kwepakati
Munzvimbo yebhizinesi, manejimendi yemaoko paAP imwe neimwe haishande zvakanaka. Saka, masangano mazhinji anoshandisa ma controllers kana mapuratifomu anodzorwa negore. Zvakanakira:
- magadzirirwo akafanana uye anokurumidza,
- nhamba dziri pakati,
