1. A repeater comprising:
- a first interface unit configured to be connected to a gateway apparatus via a Wi-Fi communication protocol over a channel in a first frequency band, the first interface comprising a first filter configured to filter the first frequency band to reduce signal noise from frequencies outside of the first frequency band; and
a second interface unit configured to be connected to a client device via the Wi-Fi communication protocol over a channel in a second frequency band, the second interface comprising a second filter configured to filter the second frequency band to reduce signal noise from frequencies outside of the second frequency band,wherein the first frequency band is a different frequency band from the second frequency band,wherein the first and the second frequency bands are spaced apart from each other by a preset number of channels or a preset frequency band, andwherein one of the first frequency band and the second frequency band comprises a frequency band higher than a dynamic frequency selection (DFS) frequency band and the other one of the first frequency band and the second frequency band comprises a frequency band lower than the DFS frequency band.

10. A repeater comprising:
-
first and second interface units respectively configured to communicate with a gateway apparatus and a client device via channels within a first frequency band and second frequency band which is defined according to a Wi-Fi communication protocol, wherein the first interface unit comprises a first filter configured to filter the first frequency band to reduce signal noise from frequencies outside of the first frequency band, and the second interface unit comprises a second filter configured to filter the second frequency band to reduce signal noise from frequencies outside of the second frequency band, and wherein the first frequency band is a different frequency band from the second frequency band; a signal detector configured to detect a frequency usage state of the particular frequency band; and a controller configured to control, when the frequency usage state of the particular frequency band detected by the signal detector indicates that the particular frequency band is being used, at least one of the first and second interface units to use channels of the respective first and second frequency bands, wherein the first and second frequency bands are different from the particular frequency band, wherein the first and the second frequency bands are spaced apart from each other by a preset number of channels or a preset frequency band, and wherein one of the first frequency band and the second frequency band comprises a frequency band higher than a dynamic frequency selection (DFS) frequency band and the other one of the first frequency band and the second frequency band comprises a frequency band lower than the DFS frequency band. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of controlling a repeater which communicates with a gateway apparatus via a first Wi-Fi connection, and which communicates with at least one client device via a second Wi-Fi connection, the method comprising:
-
filtering over a first bandwidth of a first frequency band centered on a first center frequency to reduce signal noise from frequencies outside of the first frequency band; filtering over a second bandwidth of a second frequency band centered on a second center frequency to reduce signal noise from frequencies outside of the second frequency band; receiving a broadcast signal from the gateway apparatus, wherein the broadcast signal is received over the first frequency band via the first Wi-Fi connection; and transmitting the received broadcast signal to a client device from among the at least one client device over a second frequency band via the second Wi-Fi connection, wherein the first frequency band is a different frequency band from the second frequency band, and wherein the first and the second frequency bands are spaced apart from each other by a preset number of channels or a preset frequency band, and wherein one of the first frequency band and the second frequency band comprises a frequency band higher than a dynamic frequency selection (DFS) frequency band and the other one of the first frequency band and the second frequency band comprises a frequency band lower than the DFS frequency band.
