Large-capacity wireless digital communication technology for short-distance communication

Short-range wireless communication technology has a wide range of applications. Generally speaking, as long as the sender and receiver transmit information by radio waves and the transmission distance is limited in a short range, usually within tens of meters, it can be called short-distance wireless communication. This paper introduces several mainstream short-range wireless communication technologies, including: high-speed WPAN technology; UWB high-speed wireless communication technology, including MB-OFDM and DS-UWB；; ; WirelessUSB technology, and finally introduces the application and development of short-distance wireless communication.
