1. A wireless communication device configured to be capable of performing wireless communication with at least one communication destination device, the wireless communication device being configured to operate in an operation mode, either a ROD (Radio on Demand) mode or a non-ROD mode, wherein:
the non-ROD mode is configured to set a state of the wireless communication device to an active state in which the wireless communication device can perform wireless communication compliant with a predetermined first communication scheme with the communication destination device; the ROD mode is configured to: set the state of the wireless communication device to either the active state or a sleep state in which the wireless communication device can receive an activation instruction signal compliant with a second communication scheme requiring smaller electric power to receive a signal than the first communication scheme and cannot perform wireless communication compliant with the first communication scheme with the communication destination device; in a case where the state of the wireless communication device is the active state and a predetermined sleep condition is satisfied, set the state of the wireless communication device to the sleep state; and in a case where the state of the wireless communication device is the sleep state and the wireless communication device receives the activation instruction signal, set the state of the wireless communication device to the active state, wherein the wireless communication device comprises a compatible information acquiring unit for acquiring compatible information with respect to each of the at least one communication destination devices, the compatible information representing whether the communication destination device is a ROD compatible device capable of transmitting the activation instruction signal or a ROD incompatible device incapable of transmitting the activation instruction signal and wherein the wireless communication device is configured to operate in the ROD mode in a case where the acquired compatible information represents that all of the communication destination devices are ROD compatible devices and, on the other hand, operate in the non-ROD mode in a case where the acquired compatible information represents that at least one of the communication destination devices is a ROD incompatible device, wherein the compatible information acquiring unit is configured to:
transmit, to each of the at least one communication destination devices, a notification transmission request that is a request for transmission of compatibility notification representing that the communication destination device receiving the request can transmit the activation instruction signal; andacquire, with respect to each of the at least one communication destination devices, compatible information, wherein the compatible information is one of:
compatible information representing that the communication destination device is a ROD compatible device when receiving the compatibility notification from the communication destination device in response to the transmitted notification transmission request, andcompatible information representing that the communication destination device is a ROD incompatible device when not receiving the compatibility notification from the communication destination device in response to the transmitted notification transmission request. |
