A wireless communication device comprising a communication unit, a storage, an operation unit, a communication quality measuring unit, and a controller that controls the communication unit and the storage, wherein the controller further controls the storage to store, when the operation unit detects a transmission starting operation during every channel frequency is used by other wireless communication devices, the voice data until the operation unit detects a transmission stopping operation; controls the communication unit to transmit, when every channel frequency is not used and the bit error rate is smaller than a first threshold, all pieces of voice data that have not been transmitted, and to transmit, when every channel frequency is not used and the bit error rate is between the first threshold and a second threshold, a piece of divided data having a predetermined length from a head of the voice data which has not been transmitted.

Wireless communication device, wireless communication base station, and wireless communication method

A determination unit refers to position information of a terminal device registered in a given base station device to determine ease of connection to another base station device. A generator generates, for the terminal device, guidance information to prompt the terminal device to move to a position where a likelihood of connection to the other base station device is increased, based on a result of determination in the determination unit. A transmitter transmits the guidance information generated in the generator to the terminal device.

Management device, management method, and terminal device for displaying additional information on image and displaying image

A plurality of groups each including a plurality of terminal devices are formed, and each of a plurality of base station devices assigns a channel to each group to enable communication from one of the terminal devices included in the group to which the channel is assigned to another terminal device included in the group, and a receiving unit receives information on the number of terminal devices included in the groups registered in each base station device. A display unit displays information indicating the number of terminal devices for each base station device based on the received information.

Monitoring device and memory medium for monitoring communication between terminal devices in a group

An acquirer acquires parameters that correspond to a plurality of base station devices using a resource for communication with a terminal device and can be used for predicting a shortage of a resource of each base station device. A generator generates information relating to a priority level of a resource desired to be used by a terminal device connected to one of the plurality of base station devices in accordance with the parameters acquired by the acquirer. A transmitter transmits the information generated by the generator.

Management device, terminal device, and management method performing process of selecting resource of radio link

An event information memory stores an occurrence time of an event so as to cause the occurrence time of the event to correspond to each of monitoring targets in which the events occurred (or are scheduled to occur) among a plurality of the monitoring targets. Based on position information for displaying each of a plurality of monitoring targets on a general view, a controller instructs control to draw an event display image on the general view so as to cause the event display image to correspond to the monitoring target in which the event occurred (or scheduled to occur), the monitoring target being stored in the event information memory. The event display image includes: a circular portion indicating a predetermined time in a circumferential direction, an indicator indicating a current hour or minute, and an event occurrence time display portion caused to correspond to the occurrence time of the event.

Information display device, information display method, and information display program

A plurality of groups including a plurality of terminal devices are formed, and further, each of a plurality of base station apparatuses assigns a channel in a unit of the group such that communication is performed from one of the terminal devices included in a group to which the channel is assigned to the other terminal devices included in the group, and a receiver receives information on a busy count generated in the group registered in each of the base station apparatuses. A display unit displays information indicating the busy count for each of the base station apparatuses based on the received information.
