The millimeter wave communication standard employed for the radio communication device 300 is WiGig in the above-described embodiment but is not limited thereto. For example, the millimeter wave communication standard employed for the radio communication device 300 may be various other radio communication standards with directivity, such as IEEE 802.15.3c. Similarly, the beam forming protocol is not limited to the above-described SLS.

The number and shapes of the beam patterns of the radio communication device 300 are not limited to the example described with reference to FIG. 2.

The connection switch determination condition, the switch source candidate terminal condition, and the switch destination candidate device condition are not limited to the above-described example. For example, the switch destination candidate device condition may be caused to be a condition related to the load on each of the radio communication devices 300 so as not to include the number of connections of the radio terminals 400, and the switch determiner 330 may determine the radio communication device 300 that has the lightest load and is included in the neighboring radio communication devices 300 as the switch destination candidate device 300.

The device information may indicate the reception quality at the radio terminal 400. In this case, the connection switch determination condition and the switch source candidate terminal condition can give a priority to the radio terminals 400 lower in the reception quality so that one of such radio terminals 400 becomes the switch source candidate terminal 400.
