A basic method of calculation in dB for wireless applications
In recent years, even circuit design and digital design engineers should learn radio technologies with the increase of
wireless applications. Some of those engineers may not be good at analyzing in dB. This paper presents a way how
to create level diagram of a wireless application using anechoic box.
