1. A first beacon device comprising:
- a first communication unit configured to communicate with one or more other first beacon devices in a tree topology;
a second communication unit configured to communicate with one or more second beacon devices, wherein the second beacon devices are designated within a different level in the tree topology from the first beacon devices; and
a controller configured to control transmission of a beacon signal by;
allocating a respective usable frequency as a communication channel for each of the one or more other first beacon devices; and
allocating, within a preset usable frequency that is different from the respective usable frequencies allocated to the one or more other first beacon devices, a time slot to each of the one or more second beacon devices for defining usable times during which a respective second beacon device communicates with the one or more other first beacon devices through the preset usable frequency, wherein the time slot lasts for a predetermined length of time; and
wherein the controller is configured to check usable frequencies for each different first beacon device corresponding to a parent node, a sibling node, and a child node, and allocate the respective usable frequencies to the each different first beacon devices so as not to overlap the usable frequencies of the other first beacon devices.

1. A first beacon device comprising:
-
a first communication unit configured to communicate with one or more other first beacon devices in a tree topology; a second communication unit configured to communicate with one or more second beacon devices, wherein the second beacon devices are designated within a different level in the tree topology from the first beacon devices; and a controller configured to control transmission of a beacon signal by; allocating a respective usable frequency as a communication channel for each of the one or more other first beacon devices; and allocating, within a preset usable frequency that is different from the respective usable frequencies allocated to the one or more other first beacon devices, a time slot to each of the one or more second beacon devices for defining usable times during which a respective second beacon device communicates with the one or more other first beacon devices through the preset usable frequency, wherein the time slot lasts for a predetermined length of time; and wherein the controller is configured to check usable frequencies for each different first beacon device corresponding to a parent node, a sibling node, and a child node, and allocate the respective usable frequencies to the each different first beacon devices so as not to overlap the usable frequencies of the other first beacon devices. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A non-transitory computer-readable recording medium storing a program for executing a method for setting a wireless mesh network, the program, when executed by a first beacon device, causes the first beacon device to:
-
communicate with a plurality of first beacon devices in a tree topology; allocate a respective usable frequency as a communication channel for each of the plurality of first beacon devices; connect one or more second beacon devices to at least one of the plurality of first beacon devices, wherein the second beacon devices are designated within a different level in the tree topology from the first beacon devices; and allocate, within a preset usable frequency that is different from the respective usable frequencies allocated to the one or more first beacon devices, a time slot to each of the one or more second beacon devices for defining usable times during which a respective second beacon device communicates with the one or more first beacon devices through the preset usable frequency, wherein the time slot lasts for a predetermined length of time; and allocate the respective usable frequencies by checking usable frequencies of different first beacon devices corresponding to a parent node, a sibling node, and a child node of each of the first beacon devices, and allocate the respective usable frequencies to the different first beacon devices so as not to overlap the usable frequencies of the first beacon devices. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of setting a wireless mesh network, performed by a first beacon device, the method comprising:
-
communicating with a plurality of first beacon devices in a tree topology; allocating a respective usable frequency as a communication channel for each of the plurality of first beacon devices; connecting one or more second beacon devices to at least one of the plurality of first beacon devices, wherein the second beacon devices are designated within a different level in the tree topology from the first beacon devices; and allocating, within a preset usable frequency that is different from the respective usable frequencies allocated to the one or more first beacon devices, a time slot to each of the one or more second beacon devices for defining usable times during which a respective second beacon device communicates with the one or more first beacon devices through the preset usable frequency, wherein the time slot lasts for a predetermined length of time; and wherein the allocating of the respective usable frequencies includes checking usable frequencies of different first beacon devices corresponding to a parent node, a sibling node, and a child node of each of the first beacon devices, and allocating the respective usable frequency to each first beacon device so as not to overlap the usable frequencies of the different first beacon devices. - View Dependent Claims (16)
