Alaabooyinka WiFi waxay nooga baahan yihiin inaan gacanta ku cabbirno oo aan ka saarno macluumaadka awoodda WiFi ee alaab kasta, haddaba intee ayaad ka taqaannaa cabbirrada cabbirka WiFi? Aan halkan ku baro:
1, TX Power: waxaa loola jeedaa sheyga wireless-ka gudbiya anteenada awoodda shaqada, unugga waa dBm. Awoodda gudbinta wirelessku waxay go'aamisaa xoogga iyo fogaanta calaamadaha wireless-ka. Awoodda weyn, ayaa sii xoogaysanaysa calaamadda. Naqshadaynta sheyga wireless-ka, waxaa jira awood bartilmaameed ah oo saldhig u ah naqshadeena, marka la eego aragtida la kulanka saxanka spectrum iyo EVM, awoodda gudbinta ee weyn, ayaa ka sii wanaagsan waxqabadka.
2. Dareenka RX: halbeeg tilmaamaya waxqabadka soo dhawaynta shayga la tijaabinayo. Sida wanaagsan ee dareenka soo dhawayntu u wanaagsan yahay, waxa sii badanaya calaamadaha faa'iidada leh ee ay heli doonto oo way sii badanaysaa daboolka wireless-ka. Markaad tijaabinayso dareenka helitaanka, ka samee sheyga ku jira gobolka wax helaya, isticmaal aaladda cabirida WiFi si aad u dirto faylal mowjad gaar ah, oo alaabtu hesho. Heerka awooda dirida waxa wax lagaga badali karaa aaladda cabirida WiFi ilaa heerka khaladka xidhmada (PER%) ee badeecadu la kulmo heerka
3. Ciladda Soo noqnoqota: waxay ka dhigan tahay baaxadda leexashada calaamadda RF ee inta jeer ee xarunta dhexe ee kanaalka halkaas oo calaamaduhu ku yaalliin (cutubka PPM).
4, baaxadda baaxadda qaladka (EVM): waa tilmaame lagu tixgalinayo tayada calaamadda wax-ka-beddelka, unugga waa dB. Inta yar ee EVM, ayaa ka sii wanaagsan tayada calaamadda. Badeecada wireless-ka, TX Power iyo EVM waxay la xiriiraan, weynaanta TX Power, weynaanta EVM, taas oo ah, ka sii darnaanta tayada calaamadaha, sidaas darteed codsiyada wax ku oolka ah, si ay u qaataan tanaasul u dhexeeya TX Power iyo EVM.
5. Qaabka soo noqnoqda ee calaamada la gudbiyay waxa uu cabbiri karaa tayada calaamada la kala qaado iyo awoodda xakamaynta faragelinta ee kanaalka ku xiga. Qaabka spectrum ee calaamada la cabbiray waxa uu u qalmaa qaabka caadiga ah.
6. Kanaalka, sidoo kale loo yaqaan kanaalka iyo band band, waa kanaalka gudbinta signalka xogta oo leh signalka wireless-ka (mawjada elektromagnetic) sida gudbiyaha gudbinta. Shabakadaha wireless-ka (router, AP hotspots, kaadhadhka wireless-ka kumbuyuutarka) waxay ku socon karaan kanaalo badan. Marka la eego baaxadda daboolida calaamadaha wireless-ka ee qalabka shabakadaha wireless-ka ee kala duwan waa in ay isku dayaan in ay isticmaalaan kanaalo kala duwan si looga fogaado faragelinta calaamadaha.
