Nā mea
Ma kēia ʻatikala makemake wau e kamaʻilio e pili ana i nā kumu kumu o ke kūkulu ʻana i kahi alahaka uila kiʻekiʻe, no ka mea he nui nā "mea hana pūnaewele" e manaʻoʻiʻo e lawa ke kūʻai aku i nā lako ʻoihana kiʻekiʻe, hoʻokomo a loaʻa ka 100% hoʻihoʻi mai iā lākou - ʻo ia ka mea. ʻaʻole lanakila nā kānaka a pau.
CCQ - he aha ia?
Ua unuhi ʻia ʻo CCQ (Client Connection Quality) mai ka ʻōlelo Pelekania ma ke ʻano he "kūpono pili pili" - ʻo ia ka mea, ma ke kumu, hōʻike i ka pākēneka o ka manaʻo hiki ke hiki i ke kahawai maoli o kēia manawa, ʻo ia hoʻi, ka pākēneka o ka loaʻa ʻana me ka hiki ke hiki. ma luna o nā lako kūikawā.
No ka laʻana, ke hoʻohana nei ʻoe i nā mea hana me ka hiki ke kiʻekiʻe loa o 200 Mbit/s, akā ʻo ka ʻoiaʻiʻo ʻo ke kahawai o kēia manawa ʻo 100 Mbit/s - ma kēia hihia ʻo ka CCQ he 50%
I nā lako pūnaewele и ʻelua mau hōʻailona kaʻawale
Tx. CCQ (Transmit CCQ) - ka helu hoʻoili ʻikepili.
Rx. CCQ (Loaʻa CCQ) - ka wikiwiki hoʻokipa ʻikepili.
ʻEkolu mau kumu nui e hoʻololi i ka maikaʻi o CCQ
1. Hoʻoponopono ʻelua antenna. Inā mākou e kamaʻilio e pili ana i kahi alahaka uila ʻokoʻa, ʻike maopopo ʻia e nānā pono nā antenna i kekahi i kekahi me ka pololei, "maka i ka maka."
Inā makemake ʻoe i kahi alahaka Wi-Fi point-to-multipoint, a laila pono ʻoe e noʻonoʻo i ka hoʻolālā holoʻokoʻa mai ka antenna ʻāpana o ka mea hoʻolako a hiki i ka mea kūʻai aku, i mea e hoʻopili pololei ai lākou.
2. Loaʻa ka walaʻau ma ke kahawai. Ma mua o ka hoʻoholo ʻana i ke alapine o ke alahaka Wi-Fi, e nānā pono i kēlā me kēia alapine no ka hiki ʻana o ka walaʻau, e pili ana i kēia nānā, koho i kahi alapine liʻiliʻi.
3. Wahi Fresnel.
Fresnel zone - he aha ia?
ʻO ka ʻāpana Fresnel ka leo o ke ala hawewe lekiō ma waena o nā antenna ʻelua.
Aia ka leo kaila kiʻekiʻe ma ke kikowaena waena ma waena o nā antenna ʻelua.
No ka hōʻailona kiʻekiʻe loa, pono ʻoe e koho i ka wahi maʻemaʻe, mai nā pilikia kino a mai nā nalu radio (e like me ka mea i kūkākūkā ʻia ma ka paukū ʻelua).
Pehea e helu ai i ka wahi Fresnel?
Kumu no ka helu ʻana i ka ʻāpana Fresnel ma kona kiko waena:
D—ka mamao (km)
f - alapine (GHz)
ʻO ke kumu no ka helu ʻana i ka ʻāpana Fresnel i kēlā me kēia manawa, no ka laʻana ma kahi keakea:
f - alapine (GHz)
D1 - ka mamao i ka helu helu āu e pono ai, mai ka antenna mua (km)
D2 - ka mamao i ka helu helu āu e pono ai, mai ka lua antenna (km)
Ma hope o ka hana pono ʻana i kēia mau mea ʻekolu, e loaʻa iā ʻoe kahi alahaka uʻi paʻa me ka wikiwiki hoʻoili ʻikepili kiʻekiʻe loa.
