Abstract: A wireless communication system performs high-quality communication using Multicast communication where re-transmission processing is performed. The wireless communication system includes a program distribution unit for distributing a program using the Multicast communication; a first communication path for transmitting the program distributed from the program distribution unit; first communication units; user terminals; and a second and the user terminal and is also a wireless communication path where the re-transmission of a frame is performed, wherein the first communication unit selects a Multicast frame of a program requested by the user terminal from the first communication path, converts the selected Multicast frame into a Unicast frame, and transmits the converted Unicast frame to the user terminal.

Abstract: A wireless terminal communicates with a wireless communication apparatus including one or more wireless access points, and is used in a facility including a plurality of seats. The wireless terminal includes a seat position identifying unit, a distance determination unit, and a processing setting unit. The seat position identifying unit identifies a seat position of a user of the wireless terminal. The distance determination unit determines a distance from the identified position to the one or more wireless access points. The processing setting unit sets the processing associated with communication based on the determined distance.

Abstract: A noise reduction device, including a microphone for detecting noise, a noise controller for reversing the phase of noise detected by the microphone based on information outputted from the microphone, and a speaker for outputting sound based on information outputted from the noise controller, is arranged at a seat surrounded by a shell portion having a cavity, wherein a speaker is disposed in the cavity of the shell portion.
