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 gudbinaya anteenada awoodda shaqada, unugga waa dBm.Awoodda gudbinta wirelessku waxay go'aamisaa xoogga iyo fogaanta calaamadaha wireless-ka.Awoodda weyn, ayaa sii xoogaysanaysa calaamadda.Naqshadeynta 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 si fiican u shaqeyneysa.
2. Dareenka RX: halbeeg tilmaamaya waxqabadka soo dhawaynta shayga la tijaabinayo.Sida wanaagsan ee dareenka soo dhawayntu u wanaagsan yahay, ayaa inta ay sii kordhayso calaamadaha faa'iidada leh ee ay heli doonto oo ay sii weynaato daboolka wireless-ka.Markaad tijaabinayso dareenka helista, ka samee sheyga ku jira gobolka 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 leexinta calaamadda RF ee inta jeer ee xarunta dhexe ee kanaalka halkaas oo calaamaduhu ku yaalliin (cutubka PPM).
4, Baaxadda vector-ka qaladka (EVM): waa tilmaame lagu tixgalinayo tayada calaamadda habaynta, unugga waa dB.Inta yar ee EVM, ayaa ka sii wanaagsan tayada calaamadda.Alaabada wireless-ka ah, TX Power iyo EVM waxay la xiriiraan, weynaanta TX Power, weynaanta EVM, taas oo ah, ka sii xun tayada calaamadaha, sidaas darteed codsiyada la taaban karo, 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.Shabakado aan fiilo lahayn (routers, AP hotspots, kaadhadhka bilaa-waayirka kumbuyuutarka) waxay ku socon karaan kanaalo badan.Marka la eego baaxadda daboolida calaamadaha wireless-ka ee qalabka shabakadaha wireless-ka ee kala duwan waa inay isku dayaan inay adeegsadaan kanaalo kala duwan si looga fogaado faragelinta calaamadaha.
