1. A method of configuring a network of a power transmitting unit (PTU), the method comprising:
determining whether a neighboring PTU is operating in a master mode;
determining an operation mode of a PTU based on a result of the determining;
setting a network between the PTU and the neighboring PTU based on the operation mode of the PTU; and
setting an index for either one or both of the PTU and the neighboring PTU, wherein a result of the determining of whether the neighboring PTU is operating in the master mode is that the neighboring PTU is operating in a slave mode;
the setting of the index for the either one or both of the PTU and the neighboring PTU comprises transmitting information on an index to the neighboring PTU operating in the slave mode in response to an operation mode of the PTU being a master mode,
wherein the neighboring PTU is one of a plurality of neighboring PTUs that are network-connected to the PTU, and
the transmitting of the information on the index to the neighboring PTU operating in the slave mode comprises generating the information on the index based on a sequential order in which the plurality of neighboring PTUs were network-connected to the PTU.
