CHANNEL SCANNING DEVICE AND METHOD THEREOF
First Claim
1. A channel scanning device for scanning channel status of a wireless local area network (WLAN), comprising:
- a status recording module for setting up a channel status list comprising multiple sequence fields and status fields, the sequence fields representing a channel sequence, and one sequence field corresponding to a status field, and recording the channel status into the channel list;
a probing module for pre-probing the channel in sequence according to the channel sequence fields, in order to find an idle channel, probing the idle channel; and
a transmission module for transmitting a pre-probe packet over the idle channel.

Abstract
A channel scanning device (100) for scanning channel status of a wireless local area network (WLAN) is provided. The channel scanning device includes a status recording module (120), a transmission module (130), and a probing module (140). The status recording module is used for setting up a channel status list including multiple sequence fields and status fields, the sequence fields representing a channel sequence, and one sequence field together with a status field corresponding to each channel. The probing module is used for pre-probing the channel according to the channel sequence, in order to find an idle channel, probing the idle channel, and recording the channel status into the channel status list set up by the status recording module. The transmission module is used for transmitting a pre-probe packet over the idle channel. A channel scanning method for scanning channel status of the WLAN is also disclosed.

18. A method for scanning status of channels in a wireless local area network (WLAN), comprising:
-
pre-probing preset communicable channels in a WLAN in sequence by means of transmitting a predetermined packet, including a waiting time therein which is set based on a total number of said channels, on each of said channels; and
probing said each of said channels to determine status thereof according to reply to said transmitted pocket of said each of said channels after said pre-probing step for said each of said channels is completed and said waiting time expires. - View Dependent Claims (19, 20)
