摘要： A control unit of a wireless connection terminal compares the received signal strength indicator of an access point currently connected to by the wireless connection terminal with the received signal strength indicator of a neighboring access point. If the difference between the two received signal strength indicators is higher than or equal to 40%, the connection to the current access point is severed and roaming in which the connection is switched to the neighboring access point is performed. Even when the difference between the two received signal strength indicators is not higher than or equal to 40%, roaming in which the connection is switched to the neighboring access point is performed if the received signal strength indicator of the access point to which the wireless connection terminal is currently connected becomes lower than or equal to 20%.

摘要： A communication terminal device includes a wireless LAN module configured to search a plurality of communication channels by channel scanning in order to find a communication channel available for communication and configured to perform wireless communication using the found communication channel through a wireless LAN. In a search process by channel scanning for searching for the communication channel available for communication, if the communication channel available for communication is not found within a predetermined time period from the beginning of the search process, the wireless LAN module stops the search process, and an operation mode of the wireless LAN module is shifted from a normal operation mode to a power-saving mode.
