Selles artiklis tahan r\u00e4\u00e4kida kvaliteetse traadita silla loomise fundamentaalsetest teguritest, kuna paljud \"v\u00f5rguehitajad\" arvavad, et piisab kvaliteetse v\u00f5rgu varustuse ostmisest, paigaldamisest ja 100% tootluse saavutamisest \u2013 mis l\u00f5ppkokkuv\u00f5ttes ei \u00f5nnestu k\u00f5igil.

CCQ \u2013 mis see on?<\/h2>\n

\nCCQ (Client Connection Quality) t\u00f5lgitakse inglise keelest kui \"kasutaja\u00fchenduse kvaliteet\" \u2013 see n\u00e4itab protsentuaalset suhet teoreetiliselt v\u00f5imaliku ja tegeliku kanalil\u00e4bilaskev\u00f5ime vahel, teisis\u00f5nu saavutatud l\u00e4bilaskev\u00f5ime protsenti maksimaalsest, mis konkreetsel seadmel v\u00f5imalik.<\/p>\n

N\u00e4iteks, kui kasutate varustust, mille maksimaalne l\u00e4bilaskev\u00f5ime on 200 Mbit\/s, kuid tegelikku kanalit m\u00f6\u00f6da on 100 Mbit\/s \u2013 sellisel juhul on CCQ 50%<\/p>\n

V\u00f5rgu seadmetes Mikrotik<\/a><\/noindex> ja Ubiquiti<\/a><\/noindex> on kaks eraldi indikaatorit
\nTx. CCQ (Transmit CCQ) \u2013 andmete edastuskiirus.

Kolm peamist tegurit, mis m\u00f5jutavad CCQ kvaliteeti<\/h2>\n

\n1. Kahte antenni t\u00e4psustamine.<\/b> Kui r\u00e4\u00e4kida traadita sillast \u201epunkt-punkt\u201d, siis on selge, et antennid peavad \u00fcksteisele v\u00f5imalikult t\u00e4pselt vaatama, \u201esilm silma vastu\u201d.<\/p>\n

Kui on vaja wi-fi silda \u201epunkt-mitme punktini\u201d \u2013 siis tuleb alguses l\u00e4bi m\u00f5elda kogu arhitektuur sektorantenni ja klientide vahel, et need ristuksid v\u00f5imalikult t\u00e4pselt.<\/p>\n

2. H\u00e4irete olemasolu kanalil.<\/b> Enne wi-fi silla sageduse m\u00e4\u00e4ramist tuleb kindlasti kontrollida iga sagedust h\u00e4irete suhtes, ning selle p\u00f5hjal valida v\u00e4hem koormatud sagedus.
\n<\/a><\/noindex>
\n3. Fresneli zona.<\/b><\/p>\n

Fresneli zona \u2013 mis see on?<\/h2>\n

\nFresneli zona on ruum raadiolainete kanalist kahe antenni vahel.<\/p>\n

\"Mis
\n
\nKanalite maksimaalne maht asub kahe antenni vahelisel keskpunktil. <\/p>\n

Kvaliteetse signaali saavutamiseks tuleb valida k\u00f5ige puhtam ala, nii f\u00fc\u00fcsiliste takistuste kui ka raadiolainete t\u00f5ttu (millest r\u00e4\u00e4giti teises punktis).
\n<\/a><\/noindex><\/p>\n

Kuidas arvutada Fresneli zona?<\/h2>\n

\nFresneli zona arvutamise valem selle keskpunktis:<\/b><\/p>\n

\"Mis
\n
\nD \u2014 kaugus (km)
\nf \u2014 sagedus (GHz)<\/p>\n

Freneli tsooni arvutamise valem igas punktis, n\u00e4iteks takistuse kohal:<\/b><\/p>\n

\"Mis
\n
\nf \u2014 sagedus (GHz)
\nD1 \u2014 kaugus soovitud arvutamispunkti esimesest antennist (km)
\nD2 \u2014 kaugus soovitud arvutamispunkti teisest antennist (km)<\/p>\n

Korrigeerides neid kolme tegurit, saavutate l\u00f5puks stabiilse traadita sildi, millel on maksimaalne andmeedastuskiirus.
