Abstract: 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.

Abstract: A system and method of displaying incoming pager messages on a receiver using infrared signals. The paging device includes a receiver for receiving paging signals including paged information. The output signal from the receiver is supplied to a baseband processor where it is converted into a digital signal, under the control of a processor. If the thus digitized signal is determined to be the selecting signal for the particular paging receiver, the digital signal is then preferably sent directly to a protocol translator, where it is converted into a signal having an infrared protocol. After processing in the protocol translator, the signal is then sent to a transmitter and transmitted as an infrared signal. The infrared signal is then received in a light-receiving element in a receiver where it is thereafter decoded by a protocol decoder in accordance with instructions contained in a memory connected thereto to retrieve the paging signal or paged message.
