Claim Text:
1. A method for selecting an operation channel to be implemented by a wireless network connecting apparatus, the method comprising the following steps of: (a) obtaining, by the wireless network connecting apparatus, information about at least one preoccupied channel for a first wireless network over which the wireless network connecting apparatus is able to communicate with a first wireless device through the preoccupied channel, and determining by the wireless network connecting apparatus, from a plurality of candidate channels of a second wireless network, a plurality of available channels by excluding the candidate channels that overlap with the preoccupied channel through which the wireless network connecting apparatus is able to communicate with a second wireless device, the first wireless network having a maximum data transmission rate larger than that of the second wireless network; (b) evaluating, by the wireless network connecting apparatus, a channel quality of each of the available channels over the second wireless network; (c) selecting, by the wireless network connecting apparatus, one of the available channels based on the best channel quality thereof as the operation channel, and switching by the wireless network connecting apparatus to the operation channel for the second wireless network, over which the wireless network connecting apparatus is able to communicate with the second wireless device through the operation channel; (d) transmitting, by the wireless network connecting apparatus, an evaluation packet through the operation channel to the second wireless device; (e) determining, by the wireless network connecting apparatus, whether the operation channel needs to be replaced, based on a retransmission threshold of data retransmissions by the wireless network connecting apparatus associated with the evaluation packet; and (f) when the determination made in step (e) is affirmative, excluding, by the wireless network connecting apparatus, the operation channel from the available channels, and repeating steps (b) to (e).
