Inkcazo: I- decibel (dB) iyunithi eqhelekileyo yokulinganisa amandla e- Wi-Fi engenazintambo zomsakazo ezingenazintambo. I-Decibels nayo isetyenziswe njengesilinganiselo sezinto ezivakalayo kunye nezinye i-elektroniki zombane eziquka iifowuni.
I-antenna zomsakazo ze-Wi-Fi kunye ne-transceivers zombini ziquka ukulinganisa kwe-decibel njengoko kunikwe ngumenzi. Izixhobo zonxibelelwano zasekhaya zihlala zibonisa ukulinganiswa kwiinqununu ze- dBm , apho 'm' imela ama-milliwatts yamandla kagesi.
Ngokubanzi, izixhobo ze-Wi-Fi ezinexabiso elikhulu kakhulu le-DBm liyakwazi ukuthumela okanye ukufumana inethiwekhi yomnxeba ongenazintambo kumgama omkhulu. Nangona kunjalo, ixabiso elikhulu le-DBm libonisa ukuba idivayisi ye-WiFi idinga amandla amaninzi okusebenza, okuguqulela ukunciphisa ubomi bhetri kwiinkqubo zeselula.
