摘要:
A wireless communication control system includes a first radio having a directional antenna, a second radio, a directivity control unit controlling the directivity of the directional antenna, and a directivity information storage unit storing directivity information relating to a directivity, the directivity information being applied to the directional antenna in relation to wireless communication between the first and second radios in accordance with a plurality of change patterns indicating a temporal change in a received signal intensity. The directivity control unit acquires a temporal change in a received signal intensity during wireless communication between the first and second radios, selects, from among pieces of the directivity information stored in the directivity information storage unit, directivity information corresponding to the change pattern corresponding to the temporal change in the received signal intensity, applies the selected directivity information, and executes wireless communication between the first and second radios.
摘要:
A sensor module that transmits at a predetermined transmission interval, via a network, data obtained by measurement to an externally installed information processing device sets, together with a nearby sensor module, a predetermined module group in which a plurality of sensor modules for transmitting measurement data according to data processing in the information processing device are put together. Then, together with the nearby sensor modules, one sensor module among the predetermined module group is set as a reference sensor module for which a transmission interval is maintained at a predetermined transmission interval, and transmission intervals of measurement data of sensor modules other than the reference sensor module are changed to a prolonged transmission interval that is longer than the predetermined transmission interval. With this, a reduction in power consumption is realized as much as possible in the sensor module that measures environmental parameters and transmits to the information processing device.
