Abstract:
A wireless terminal and data receiving and transmitting methods thereof are described. When the wireless terminal receives data, an antenna is used for receiving receipt signals from an uplink band and a downlink band, allowing mixed signals to enter a duplexer. The duplexer separates receipt signals from the uplink band and downlink band, and passes the receipt signal from the downlink band through a downlink band receiving end and passes the receipt signal from the uplink band through a shift switch to enter a central processing unit for aggregation together.
Abstract:
A nonradiative communication terminal and a communication system which use visible light for communication are provided. The nonradiative communication terminal includes a visible light emission module, a visible light reception module, and a central processing unit. The visible light emission module and the visible light reception module are connected with the central processing unit. By using visible light to communicate with other visible light communication terminals, the advantages, such as nonradiation, saving frequency resources, stability and reliability in communication performance, low-cost communication, and high transmission speed are achieved.
