Abstract: A method for acquiring telecommunication regulations and a system applying the same are provided. The method allows a wireless communication device to acquire the telecommunication regulations, and the system is applicable in the wireless communication device. In the method, a driver installed in the wireless communication device is executed to drive a wireless communication module of the wireless communication device. In the meantime, the driver can obtain location data from a BIOS or an operating system, or through environment detection. The driver uses the location data to compare the multiple telecommunication regulations recorded in program codes of the driver, so as to obtain the telecommunication regulation corresponding to the location data. Therefore, the system having the wireless communication module can operate according to the telecommunication regulation corresponding to the location data.

Abstract: A method of selecting access point, suitable for a communication device, includes following operations: (a) monitoring a channel of at least one frequency band; (b) calculating a first count that the channel is detected to be in an occupied state; (c) calculating a second count that the channel is detected to have an ambient noise; (d) repeating steps (a) through (c) to obtain the first count and the second count of each of a plurality of channels used by a plurality of access points; (e) obtaining a plurality of received signal strength indications (RSSIs) of the plurality of access points, respectively; and (f) selecting a target channel from the plurality of channels and a target access point from the plurality of access points to perform connection according to the plurality of RSSIs and the first count and the second count of each of the plurality of channels.

Abstract: A power managing method applied to a wireless network apparatus includes the steps of periodically detecting whether the wireless network apparatus is operated in a non-link status to determine whether to enter a first power-saving mode when the wireless network apparatus powered on; and determining the wireless network apparatus whether to enter a second power-saving mode according to an information of a beacon received by the wireless network apparatus when the wireless network apparatus is operated in a link status. When the wireless network apparatus is detected to be operated in the non-link status, control the wireless network apparatus to enter the first power-saving mode by a power mode controlling circuit. The first power-saving mode is an inactive power-saving mode, and the second power-saving mode is a linked power-saving mode.
