\u00cen acest articol voi discuta despre factori fundamentali \u00een construirea unui pod wireless de calitate, deoarece mul\u021bi \u201econstructori de re\u021bele\u201d consider\u0103 c\u0103 este suficient s\u0103 achizi\u021bioneze echipamente de re\u021bea de calitate, s\u0103 le instaleze \u0219i s\u0103 ob\u021bin\u0103 100% randament de la acestea \u2014 lucru care nu reu\u0219e\u0219te pentru toat\u0103 lumea.

CCQ \u2014 ce este?<\/h2>\n

\nCCQ (Calitatea Conexiunii Clientului) se traduce din englez\u0103 ca \u201ecalitatea conexiunii clientului\u201d \u2014 care arat\u0103, \u00een principiu, raportul procentual \u00eentre l\u0103\u021bimea de band\u0103 teoretic posibil\u0103 \u0219i l\u0103\u021bimea de band\u0103 real\u0103 curent\u0103 a canalului, cu alte cuvinte, procentul de l\u0103\u021bime de band\u0103 atins\u0103 \u00een raport cu maximul posibil pe echipamentul specific.<\/p>\n

De exemplu, dac\u0103 folosi\u021bi echipamente cu o l\u0103\u021bime de band\u0103 maxim posibil\u0103 de 200 Mbps, iar \u00een realitate pe canalul curent sunt 100 Mbps \u2014 \u00een acest caz CCQ este 50%<\/p>\n

Trei factori principali care influen\u021beaz\u0103 calitatea CCQ<\/h2>\n

\n1. Alinierea celor dou\u0103 antene.<\/b> C\u00e2nd vine vorba de un pod wireless punct-la-punct, este clar c\u0103 antenele trebuie s\u0103 se uite una la cealalt\u0103 c\u00e2t mai precis, \u201eochi \u00een ochi\u201d.<\/p>\n

Dac\u0103 ave\u021bi nevoie de un pod Wi-Fi punct-la-multipunct \u2014 trebuie s\u0103 planifica\u021bi \u00eentreaga arhitectur\u0103 de la antena sectorial\u0103 a furnizorului p\u00e2n\u0103 la cele ale clien\u021bilor, astfel \u00eenc\u00e2t s\u0103 se intersecteze c\u00e2t mai bine.<\/p>\n

2. Prezen\u021ba zgomotului \u00een canal.<\/b> \u00cenainte de a decide asupra frecven\u021bei podului Wi-Fi, verifica\u021bi fiecare frecven\u021b\u0103 pentru a identifica zgomotul, baz\u00e2ndu-v\u0103 pe aceast\u0103 evaluare, alege\u021bi o frecven\u021b\u0103 mai pu\u021bin aglomerat\u0103.

\n3. Zona Fresnel.<\/b><\/p>\n

Zona Fresnel \u2014 ce este?<\/h2>\n

\nZona Fresnel este volumul canalului de unde radio \u00eentre cele dou\u0103 antene.<\/p>\n

\"Ce
\n
\nVolumul maxim al canalului se afl\u0103 \u00een punctul central \u00eentre cele dou\u0103 antene. <\/p>\n

Pentru un semnal de calitate maxim\u0103, trebuie s\u0103 alege\u021bi cea mai curat\u0103 zon\u0103, at\u00e2t de la obstacole fizice, c\u00e2t \u0219i de la cele de unde radio (a\u0219a cum s-a men\u021bionat \u00een punctul doi).
\n<\/a><\/noindex><\/p>\n

Cum se calculeaz\u0103 zona Fresnel?<\/h2>\n

\nFormula de calcul a zonei Fresnel \u00een punctul s\u0103u central:<\/b><\/p>\n

\"Ce
\n
\nD \u2014 distan\u021ba (km)
\nf \u2014 frecven\u021ba (GHz)<\/p>\n

Formula de calcul a zonei Fresnel \u00een orice punct, de exemplu, \u00een locul unui obstacol:<\/b><\/p>\n

\"Ce
\n
\nf \u2014 frecven\u021ba (GHz)
\nD1 \u2014 distan\u021ba p\u00e2n\u0103 la punctul de calcul dorit, de la prima anten\u0103 (km)
\nD2 \u2014 distan\u021ba p\u00e2n\u0103 la punctul de calcul dorit, de la a doua anten\u0103 (km)<\/p>\n

Analiz\u00e2nd bine ace\u0219ti trei factori, ve\u021bi ob\u021bine un pod wireless stabil, cu viteza maxim\u0103 de transfer a datelor posibil\u0103.
