A communication system that performs first communication and second communication, which differs from the first communication, through wireless connection between a terminal and a communication peer, is provided. The communication system includes communication devices arranged in the communication peer. At least one of the communication devices performs the second communication. The communication devices include a first communication device and a second communication device, which differs from the first communication device. The first communication device is connected to a controller that controls the communication devices, and the second communication device is connected to the first communication device.

A communication system includes a master device and a slave device. The master device can transmit a signal to a slave device. The slave device includes an antenna, a sensor unit, an RFID unit, a changeover switch that connects the antenna to one of the sensor unit and the RFID unit, and a switching circuit that switches the changeover switch based on a switching signal transmitted from the master device. When the antenna in the slave device receives the switching signal from the master device, the switching circuit switches the changeover switch in the slave device from a state in which the antenna and the sensor unit are connected to a state in which the antenna and the RFID unit are connected, in accordance with the switching signal.

A wireless tag system includes: a tag signal antenna configured to receive a tag signal transmitted from a wireless transmission tag; and a communication area shaping antenna configured to transmit a reception area shaping signal for narrowing an area in which the tag signal antenna can communicate with the wireless transmission tag, wherein the tag signal antenna and the communication area shaping antenna are arranged for each prescribed product unit in a group of products that are arranged.

There is provided a communication apparatus, a communication method, and a program that enable short-range wireless communication to be made speedily with various communication parties different in model and service. The communication apparatus includes: a first short-range wireless communication unit configured to communicate with a communication party, via first short-range wireless communication; an acquisition unit configured to acquire, prior to the communication via the first short-range wireless communication, identification information notified from the communication party, via second short-range wireless communication wider in communicable range than the first short-range wireless communication; and a control unit configured to control the first short-range wireless communication unit and the acquisition unit, in which the control unit acquires a parameter file corresponding to the identification information having been acquired, and sets, on the basis of the parameter file, a parameter for the first short-range wireless communication to the first short-range wireless communication unit.

There is provided an information processing device including: a processing unit configured to select a first processing mode in which static information is transmitted or a second processing mode in which dynamic information according to a process is transmitted on a basis of a predetermined request recognized in contactless communication with an external device and to perform a process corresponding to a selected processing mode. The processing unit selects the first processing mode in a case in which the recognized predetermined request is a read request for causing information to be transmitted and selects the second processing mode in a case in which the recognized predetermined request is a write request for causing information to be written in a recording medium.

A vehicle (20) transmits an LF command (Wa), an electronic key (30) transmits, to the vehicle (20), an RF command responsive to the LF command (Wa), the vehicle (20) transmits, to the electronic key (30), an LF command (Wb) having a longer packet length than the LF command (Wa), and the electronic key (30) transmits, to the vehicle (20), an RF command responsive to the LF command (Wb) on the basis of the electric field strength of an LF-RSSI burst of a part of the LF command (Wb), thus turning on an interior light (501).

A satellite communications system is disclosed, the system comprising a ground controller, a decode-and-forward (DF) satellite transponder, and a digital high-power amplifier (HPA). The DF is further comprised of a transponder front end including a digital channelizer and a predistorter. The ground controller is configured to transmit multiple-access frequency-division-multiplexed signals to the DF, where the DF is configured to down-convert the signals received at the transponder front end. The digital channelizer is configured to convert the signals received into a single sample steam and feed the stream through the predistorter into the single digital HPA, wherein the HPA is configured to amplify each input sample of the stream in sample-by-sample fashion and generates a discrete output. The DF is further configured to convert the output of the digital HPA to a continuous time signal and up-convert the output with a main carrier frequency for down-link transmission to multiple-access ground users.
