Wireless communication device, communication control method, and computer program

A base station apparatus, configured to establish a wireless link for a backhaul line with a relay apparatus, and provide a first period in which a radio resource is used by the base station apparatus for the backhaul line, and a second period in which the radio resource is not used by the backhaul line.

Base station apparatus, terminal apparatus, and control methods for the same for cellular communication network in which relay communication is performed

Provided is a display antenna including a display including a plurality of light emitters arranged in a grid, an antenna array having an antenna assembly in which a plurality of patch antennas through which light in a wavelength band of a visible region is transmitted is disposed in a grid, the antenna array being disposed to be superimposed on the display, and a phase shifter disposed in a gap region sandwiched between the plurality of light emitters, connected to at least one of the plurality of patch antennas, and configured to shift a signal to be transmitted and received.

Display antenna

A relay apparatus for wirelessly relaying communication between a base station apparatus and a terminal apparatus determines, when a connection destination apparatus of wireless connection in a relay path is changed while being connected to a first base station apparatus via a relay path, whether a base station apparatus connected via the changed connection destination apparatus is the first base station apparatus or a second base station apparatus different from the first base station apparatus, and executes, when the base station apparatus connected via the changed connection destination apparatus is the second base station apparatus, first setting concerning a relay path after the change, and executing, when the base station apparatus connected via the changed connection destination apparatus is the first base station apparatus, second setting different from the first setting and concerning a relay path after the change.

Relay apparatus for relay communication, control method, and storage medium

Provided is an antenna device including an antenna array including a plurality of patch antennas arrayed in a grid, a first switch group including a first switch disposed on a wiring line connecting two adjacent patch antennas, and a second switch group including a second switch disposed on a wiring line between an antenna assembly formed by at least four adjacent patch antennas and a signal source connected to at least one patch antenna constituting the antenna assembly.

Antenna device and display antenna

A radio communication apparatus makes it possible to prevent contents of communication from being intercepted. The radio communication apparatus includes a generation unit configured to generate a first unique word based on operation time information of the radio communication apparatus before communication with a radio communication apparatus is started, and generate, for each radio frame, an ith unique word (i: an integer equal to or greater than two) based on an (i−1)th unique word when the communication is started, and a transmitting unit configured to transmit a first radio frame including the first unique word and an ith radio frame including the ith unique word to the radio communication apparatus.

Radio communication apparatus and radio communication method

A management device is configured to acquire a flight-schedule time/date, a flight-start position, and a flight-end position with respect to a flight device, to determine a plurality of base stations based on the flight-start position and the flight-end position, to estimate allocatable radio resources, which are allocated to the flight device at the flight-schedule time/date by each of the base stations, according to the history information of the communication status of the base stations, to compare allocatable radio resources to the flight device with necessary radio resources scheduled to be used for a communication of the flight device, and to thereby set a flight route of the flight device over a cell of a base station which provides allocatable radio resources to the flight device larger than necessary radio resources scheduled to be used for the communication of the flight device.

Management device, flight management system, flight management method and program

A non-limiting example game system includes a processor incorporated within a main body apparatus, and the processor creates, based on operation inputs of a player, a game stage by selecting components corresponding to a virtual room and by arranging panels corresponding to the components on a grid-shaped arrangement area. In the virtual room, a passage, a stairs, a door with lock blocking the passage and a treasure chest are arranged. A key for releasing the door with lock is contained in the treasure chest. The player creates the game stage by connecting all of the passages and the stairs from a start room that a game is started to a room where a boss enemy object is arranged and by taking arrangement of the doors with lock and the treasure chests containing the key into consideration.

Storage medium, information processing apparatus, information processing system and information processing method

A processor () in a wireless terminal () executes a communication service application to thereby perform an operation as a client for using a communication service. Further, in an abnormal situation where the wireless terminal () cannot access a server system () of an operator of the communication service, the processor () executes a predetermined activation procedure in the wireless terminal () without passing through the server system () to thereby activate a special account in the wireless terminal (). This makes it possible, for example, to perform communication by the special account using an online service application installed in the wireless terminal during an abnormal situation where the wireless terminal cannot access the online service server.

Wireless terminal and method for messaging

A node in a DTN includes: a memory; and a processor coupled to the memory and configured to execute data transfer processing for the DTN, wherein the data transfer processing including: receiving a plurality of bundles to be transferred to a same destination node on the DTN, each of the plurality of bundles including any one of a plurality of data segments acquired by dividing data of a content; deleting a part of the bundles from among the plurality of bundles without transferring to any other node or compressing a data size of a payload of the part of the bundles in accordance with a communication status of the DTN; and transmitting either a rest of the bundles excluding the deleted part of the bundles or the plurality of bundles including the part of the bundles having the compressed payloads to the DTN for transmitting to the destination node.

Apparatus and method for data delivery in delay-tolerant network (DTN)

A processor () implemented in a wireless terminal () is configured to perform gateway processing by executing a first application program () stored in a memory (). The gateway processing includes: (a) receiving transmission data of other application programs (-); (b) selecting, from a plurality of communication interfaces (-), at least one communication interface to which the transmission data is to be transmitted; and (c) sending the transmission data to the selected at least one communication interface. This contributes, for example, to allowing an application program to easily communicate via a communication interface (i.e., communication path) conforming to a communication protocol that is additionally installed on a wireless terminal (e.g., smartphone).
