FDMA, TDMA, and CDMA Multiple Access: Effective Utilization of Signals (Bandwidth) in Wireless Communication (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.

Noise Suppression Measures for Wi-Fi 6 (2)

Wi-Fi 6 achieves high-speed communication by adopting a new modulation system, but this can create new noise problems. Moreover, problems are also created by the mixing of the 2.4-GHz band and the 5-GHz band. This section introduces ways to handle these problems.
