A communication system includes plural application servers; a first base station and a second base station; and a radio communication apparatus configured to use one of the application servers via the first base station, wherein, when the radio communication apparatus is handed over to the second base station, it is determined whether to switch the application server that the radio communication apparatus uses to another application server based on a communication quality of a communication path including the communication path between the second base station and the application server.

Communication system, communication method and radio communication apparatus

A radio wave detecting apparatus that can perform carrier sense of radio waves subjected to spread spectrum with a simple configuration, in which a spread code is multiplied by an information signal, the band is spread, and a spread information signal is generated. A beacon signal in a predetermined band is synthesized with the spread information signal, and a synthesized signal is transmitted as a radio wave. Furthermore, only a signal component in a predetermined band is extracted from a received radio wave, so that a beacon signal is separated. The presence of a radio wave is detected based on the receiving power of the separated beacon signal. If the presence of the radio wave is detected, the transmission of the radio wave is stopped.

Spread spectrum transmitting and receiving apparatus using a beacon signal for carrier sensing

Each wireless communication apparatus forming a wireless network has an operation mode in which a wireless communication apparatus becomes a control station with priority, an operation mode in which a wireless communication apparatus may operate as a control station, and an operation mode in which a wireless communication apparatus does not become a control station. By providing a function in which a user selects and sets one of these three operation modes, the wireless network can be constructed as desired by the user. As a result of providing the mode in which the wireless communication apparatus does not become a control station, a wireless communication apparatus that is connected to a device but that cannot operate as a control station is not specified as a control station. Therefore, by allowing a specific apparatus in the wireless network to function as a control station, the wireless network can be constructed.

Wireless communication system, wireless communication control method, wireless communication apparatus, method of controlling the wireless communication apparatus, and computer program

A communications system sets a network frame period that can be repeatedly used by a plurality of wireless networks in a predetermined time period. A plurality of channel slots for use by each of the wireless networks is prepared in advance in the network frame. A coordinator operating a PAN activates its PAN in an area of a channel slot that is not used by the other coordinator(s). Since each of the wireless networks detects an unused channel slot in the network frame and uses the unused channel slot, the association process is greatly simplified.
