Abstract: In the QoS control system of the wireless LAN network including the wireless LAN access points, and the wireless LAN terminals to be connected thereto, the wireless LAN access point authenticates the user on the basis of the recorded user's authentication information when the user carries out the authentication request from the wireless LAN terminal. The wireless LAN access point is connected to the servers to notify the wireless LAN access point of the information for identifying the wireless LAN terminal and the recorded user's QoS service content through the communication network. The wireless LAN access point and the wireless LAN terminal carry out the priority control in accordance with the priority information of the QoS service from the server. Even when the terminal to be used is changed, if the same user logs onto the certificate server by using the same authentication information, the same QoS service can be offered consistently.

Abstract: A wireless LAN base station is provided with a noise signal scanning antenna separately from a wireless signal reception antenna. An attenuation circuit section attenuates the received signal from the noise scanning antenna according to an attenuation factor from an attenuation factor storage section. A distance setting storage section stores a distance between the wireless signal reception antenna and the noise scanning antenna. An attenuation factor storage section holds pieces of data each of which indicates the relationship between the distance between the antennas and an attenuation factor in the form of a table. An attenuation circuit section employs the attenuation factor so as to attenuate the received signal from the noise signal scanning antenna. A subtraction circuit section subtracts an output signal of the attenuation circuit section from the signal from the wireless signal reception antenna, and reduces or eliminates a noise from the received signal from the wireless signal reception antenna.

Abstract: If a PHS wireless LAN combo is constituted in which a PHS base station and a wireless LAN base station are placed in the same case, their frequency bands are different but they interfere with each other due to an influence of higher harmonics, which decreases communication efficiency. When a PHS base station is in a transmitting state and a wireless LAN base station is in a receiving state, a transmission signal from the PHS base station is multiplied by a predetermined attenuation ratio so as to subtract an attenuated value from a received signal of the wireless LAN base station, and when the wireless LAN base station is in a transmitting state and the PHS base station is in a receiving state, a transmission signal from the wireless LAN base station is multiplied by the predetermined attenuation ratio so as to subtract an attenuated value from a received signal of the PHS base station.

Abstract: A first wireless LAN base station is in an active state. A second wireless LAN base station is in a power off state or a power save mode. The first wireless LAN base station and the second wireless LAN base station are disposed in the same support area. When a fault occurs in the first wireless LAN base station and a communication state of the wireless LAN deteriorates, the first wireless LAN base station detects the fault and places the second wireless LAN base station in the active state. When the first wireless LAN base station confirms that the second wireless LAN base station has been placed in the active state, the first wireless LAN base station sends setting thereof to the second wireless LAN base station. When the first wireless LAN base station confirms that the setting of the second wireless LAN base station is the same as the setting of the first wireless LAN base station, the first wireless LAN base station enters the power off state or the power save mode.
