1. A wireless communication system comprising a first wireless communication device wirelessly communicating with a second wireless communication device to establish a first provisioning network, the second wireless communication device receiving at least one provisioning parameter from the first wireless communication device over the first provisioning network to join a target communication network that is different from the first provisioning network,
the first wireless communication device having:
a receiver configured to receive a router advertisement transmitted from another wireless communication device in a second provisioning network that is different from the first provisioning network and the target communication network, the router advertisement designating a channel hopping pattern used by the another wireless communication device, the channel hopping pattern used by the another wireless communication device identifying a plurality of channels and a time slot for using each of the plurality of channels, the channel hopping pattern used by the another wireless communication device including at least one time slot not used for the plurality of channels and at least one channel in the plurality of channels that is not used;
a generator configured to generate, when the router advertisement is received by the receiver, a channel hopping pattern that does not use a same channel at a same time defined in the channel hopping pattern designated by the router advertisement received by the receiver, and configured to select, when the router advertisement is not received by the receiver, a channel hopping pattern prescribed in advance; and
a transmitter configured to transmit a router advertisement designating the generated channel hopping pattern after the generator generates the generated channel hopping pattern when the router advertisement is received by the receiver, and configured to transmit a router advertisement that designates the channel hopping pattern selected by the generator after the generator selects the channel hopping pattern when the router advertisement is not received by the receiver, and
the second wireless communication device receiving the router advertisement transmitted from the first wireless communication device to establish the first provisioning network with the first wireless communication device using the channel hopping pattern designated in the router advertisement received from the first wireless communication device,
wherein the generator is configured to generate the channel hopping pattern which uses only the at least one time slot not used for the plurality of channels and the at least one channel in the plurality of channels that is not used in the channel hopping pattern used by the another wireless communication device.
