To provide a wireless LAN system in which a wireless LAN terminal that is shut down or on standby can be controlled and activated from a remote site even in the environment where the connection is attested by an authentication server, using the security technology for wireless LAN, a different encryption key from other terminals is employed in the communication, and the encryption key is periodically renewed. A wireless LAN access point controls a beacon transmission interval control part by recognizing a terminal activation instruction signal from a management terminal. The beacon transmission interval control part controls the transmission interval of beacon by switching between a normal operation mode and a patterned transmission interval mode. A beacon transmission interval detection circuit of a wireless LAN terminal always monitors the interval of beacon, and upon detecting patterned beacons, outputs a detection signal. A wireless LAN module receives the detection signal from the beacon transmission interval detection circuit, and then makes an activation request to the wireless LAN terminal.
A wireless LAN (Local Area Network) system for activating a wireless LAN terminal in either a shutdown or standby state upon an instruction via a wireless LAN access point from a remote management terminal in a network using a security technology for wireless LAN, said wireless LAN access point comprising control means issuing the activation instruction to said wireless LAN terminal using an unencrypted beacon.
A wireless LAN (Local Area Network) access point for use in a wireless LAN system for activating a wireless LAN terminal in either a shutdown or standby state upon an instruction from a remote management terminal in a network using a security technology for wireless LAN, said wireless LAN access point comprising control means issuing the activation instruction to said wireless LAN terminal using an unencrypted beacon.
A wireless LAN (Local Area Network) terminal that is activated in either a shutdown or standby state upon an instruction via a wireless LAN access point from a remote management terminal in a network using a security technology for wireless LAN, said wireless LAN terminal comprising detection means detecting an unencrypted beacon from said wireless LAN access point, wherein said wireless LAN terminal is activated based on the detected beacon.
An activation control method for use with a wireless LAN (Local Area Network) system for activating a wireless LAN terminal in either a shutdown or standby state upon an instruction via a wireless LAN access point from a remote management terminal in a network using a security technology for wireless LAN, the method comprising a control step of issuing the activation instruction from said wireless LAN access point to said wireless LAN terminal using an unencrypted beacon.
