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.

What Is Low-Power Wide-Area (LPWA) Wireless Communication? - Utilization

Low-Power Wide-Area (LPWA) is wireless communication technology that features low power consumption and wide-area and long-distance communication. Although the amount of communication data is small, communication over 10 km is possible. LPWA is attracting attention as the fundamental technology behind the Internet of Things (IoT) and Machine-to-Machine (M2M) technologies in the smartification of factories, logistics, agriculture, housing, life infrastructure, and other facilities. We explain in this article LPWA utilization examples and Murata Manufacturing’s LPWA modules.
