Zamkatimu
M'nkhaniyi ndikufuna kunena za zinthu zofunika kwambiri pomanga mlatho wopanda zingwe, popeza ambiri "omanga ma netiweki" amakhulupirira kuti zikhala zokwanira kugula zida zapamwamba zapaintaneti, kukhazikitsa ndikupeza 100% kubwerera kuchokera kwa iwo. pamapeto pake si onse amene amapambana.
CCQ - ndichiyani?
CCQ (Client Connection Quality) amamasuliridwa kuchokera ku Chingerezi monga "client Connection quality" - yomwe, makamaka, imasonyeza chiΕ΅erengero cha chiwerengero cha zomwe zingatheke ndi njira yomwe ilipo panopa, mwa kuyankhula kwina, peresenti ya zomwe zatheka ndi zomwe zingatheke. pa zida zapadera.
Mwachitsanzo, mukugwiritsa ntchito zida zomwe zimatha kupitilira 200 Mbit / s, koma kwenikweni njira yamakono ndi 100 Mbit / s - pakadali pano CCQ ndi 50%
Mu zida za netiweki ΠΈ pali zizindikiro ziwiri zosiyana
Tx. CCQ (Transmit CCQ) - kuchuluka kwa kusamutsa deta.
Rx. CCQ (Landirani CCQ) - liwiro lolandirira deta.
Zinthu zitatu zazikulu zomwe zimakhudza mtundu wa CCQ
1. Kusintha kwa tinyanga ziwiri. Ngati tilankhula za mlatho wopanda zingwe wolunjika ku nsonga, zikuwonekeratu kuti tinyanga ziyenera kuyang'anizana molondola momwe zingathere, "diso ndi diso."
Ngati mukusowa mlatho wa Wi-Fi wapoint-to-multipoint, ndiye kuti poyamba muyenera kuganizira zomangamanga zonse kuchokera ku antenna ya gawo la wothandizira kupita kwa kasitomala, kuti adutse molondola momwe angathere.
2. Kukhalapo kwa phokoso mu njira. Musanasankhe pafupipafupi pa mlatho wa Wi-Fi, onetsetsani kuti mwayang'ana pafupipafupi kuti pakhale phokoso, potengera cheke ichi, sankhani ma frequency ochepera.
3. Fresnel zone.
Fresnel zone - ndichiyani?
Fresnel zone ndi kuchuluka kwa mayendedwe a wailesi pakati pa tinyanga ziwiri.
Voliyumu yayikulu kwambiri ya chiteshi imakhala pakatikati pakati pa tinyanga ziwirizi.
Kuti mukhale ndi chizindikiro chapamwamba kwambiri, muyenera kusankha malo oyera kwambiri, kuchokera ku zopinga zakuthupi komanso kuchokera ku mafunde a wailesi (monga momwe tafotokozera m'ndime yachiwiri).
Momwe mungawerengere zone ya Fresnel?
Fomula yowerengera malo a Fresnel pakatikati:
D - mtunda (km)
f - pafupipafupi (GHz)
Njira yowerengera malo a Fresnel nthawi iliyonse, mwachitsanzo pa chopinga:
f - pafupipafupi (GHz)
D1 - mtunda wopita kumalo owerengera omwe mukufuna, kuchokera pa mlongoti woyamba (km)
D2 - mtunda wopita kumalo owerengera omwe mukufuna, kuchokera pa mlongoti wachiwiri (km)
Pambuyo pochita bwino pazifukwa zitatuzi, mudzapeza mlatho wosasunthika wopanda zingwe wokhala ndi liwiro lapamwamba kwambiri losamutsa deta.
