Abstract

A networking apparatus and channel switching method being used by the same, wherein the networking apparatus includes a beacon frame checking unit which determines whether a beacon frame to be transmitted to a device has been transmitted, a channel searching unit which searches for another channel as a result of the determination, and a first channel switching unit which switches a current channel to another channel as a result of the search.

Claims

1. A wireless networking apparatus comprising:

a beacon frame checking unit which determines whether a beacon frame to be transmitted to a device has been transmitted;

a channel searching unit which searches for another channel according to a result of the determination by the beacon frame checking unit; and

a channel switching unit which switches a current channel to the other channel which is found as a result of the search by the channel searching unit.

2. The apparatus of claim 1, further comprising a memory unit, wherein the channel searching unit stores channel information associated with the other channel in the memory unit.

3. The apparatus of claim 2, wherein the beacon frame checking unit determines whether the transmission has been successful based on an interrupt produced when transmitting the beacon frame.

4. The apparatus of claim 3, wherein the channel searching unit searches for the other channel according to a predetermined search condition, if a number of transmission failures of the beacon frame exceeds a reference number of failures.

5. The apparatus of claim 3, wherein the channel searching unit updates channel information stored in the memory unit with the channel information associated with the other channel.

6. The apparatus of claim 2, wherein the channel searching unit transmits the channel information associated with the other channel to a station existing in a wireless network to which wireless networking apparatus belongs.

7. A wireless networking apparatus comprising:

a channel information receiving unit which receives channel information from a device;

a memory unit which stores the channel information received by the channel information receiving unit therein; and

a channel switching unit which switches a current channel to a channel specified in the channel information stored in the memory unit.

8. The apparatus of claim 7, wherein the channel information is received if a number of transmission failures of the beacon frame exceeds a reference number of failures.

9. The apparatus of claim 8, wherein the channel specified in the channel information is a current channel of the device.

10. A channel switching method of a wireless networking apparatus, the method comprising:

determining whether a beacon frame to be transmitted to a device has been transmitted;

searching for another channel as a result of the determining; and

switching a current channel of the wireless networking apparatus to the other channel which is found as a result of the searching.

11. The method of claim 10, wherein transmission of the beacon frame is determined based on an interrupt of beacon transmission produced when transmitting the beacon frame.

12. The method of claim 11, wherein the other channel is searched according to a predetermined search condition if a number of transmission failures of the beacon frame exceeds a reference number of failures.

13. The method of claim 12, further comprising storing channel information associated with the other channel which is found as a result of the searching.

14. The method of claim 12, further comprising transmitting the channel information associated with the other channel to a station existing in a wireless network to which wireless networking apparatus belongs.

15. A channel switching method of a wireless networking apparatus, the comprising:

receiving channel information from a device;

storing the channel information which is received; and

switching a current channel of the wireless networking apparatus to a channel specified in the channel information.

16. The method of claim 15, wherein the channel information is received if a number of transmission failures of the beacon frame exceeds a reference number of failures.

17. The method of claim 16, wherein the channel specified in the channel information is a current channel of the device.
