Incazelo: I- decibel (dB) iyunithi ejwayelekile yokulinganisa amandla wezimpawu zomsakazo ezingenantambo ze- Wi-Fi . Ama-decibel asetshenziselwa njengendlela yokusebenzisa imishini yokulalelwayo namanye ama-electronics omsakazo kuhlanganise namakhalekhukhwini.
Ama-antenna omsakazo we-Wi-Fi nama- transceivers womabili afaka izilinganiso ze-decibel njengoba kunikezwe umenzi. Imishini yenethiwekhi yasendaweni ngokuvamile iveza ukulinganisa kumayunithi e- dBm , lapho 'm' imelela ama-milliwatts kagesi kagesi.
Ngokuvamile, imishini ye-Wi-Fi ene-dBm yenani elikhulu kakhulu ekwazi ukuthumela noma ukuthola i-network wireless traffic ezindaweni ezikude. Noma kunjalo, amanani amakhulu we-dBm akhombisa futhi ukuthi idivaysi ye-WiFi idinga amandla amaningi okusebenza, okuhumusha ekunciphiseni impilo yebhethri kumasistimu weselula.
