Understanding the RF path - CommScope
www.commscope.comWireless communication is a mature science. RF systems have been in commercial use since the 1940s, with the earliest examples including community repeaters, paging systems, point-to-point links and specialized mobile radio (trunked) systems. More recent innovations and uses of the RF spectrum include the cellular radio networks we are all now ...
