FDMA, TDMA, and CDMA Multiple Access: Effective Utilization of Bandwidth (2)

The smartphones used by all sorts of people today are capable of transferring audio, image, and video data without interference. This is possible thanks to technologies that prevent problems such as the overlapping of different streams of data or interference from noise. This article describes two such technologies: “multiplexing,” which is aimed at enabling efficient utilization of radio signals, and “multiple access,” which makes use of multiplexing technology.
