Abstract: Data communicated on one wireless channel is converted and communicated via a wired line. Alternatively, data communicated on a plurality of wireless channels is bundled and communicated via a wired line using a number of channels smaller than that of the wireless channels. In a case where another wireless communication apparatus wishes to use a wireless communication channel when a plurality of wireless channels are being used for communication, some of the plurality of wireless channels are released, thereby making it possible for the other communication apparatus to perform communication even when communication is being carried out using the plurality of wireless channels. When communication by the other wireless communication apparatus subsequently ends, communication on the original number of wireless channels is resumed.

Abstract: In a wireless communication system capable of communication with a frequency hopping method, if predetermined control information is received from a third wireless communication device while a first wireless communication device is in communication with a second wireless communication device, the first wireless communication device interrupts the communication with the second wireless communication device and executes communication with the third wireless communication device. When the communication between the first and third wireless communication devices is terminated, the communication with the second wireless communication device is re-started. All these communications are executed in a same hopping pattern, and the second wireless communication device switches the frequency according to such hopping pattern even while the communication is interrupted.

Abstract: A digital signal radio communication system employing frequency hopping for multi-purpose data processing apparatuses communicates predetermined information to a multi-purpose data processing apparatus by transmitting a carrier to a predetermined number of time slots of a communication frame having a plurality of time slots and communicates different information in accordance with which time slot the carrier is to be transmitted to among the plurality of time slots. A detector detects whether the carrier is in the predetermined number of time slots among the plurality of time slots or in more than the predetermined number of time slots. A controller performs control based on the carrier when the detector detects that the carrier is in the predetermined time slots, and judges that noise is generated when the detector detects the carrier in more than the predetermined number of time slots.

Abstract: Radio communication method and apparatus that performs communication as follows. When a radio communication apparatus receives data transmitted by data terminal equipment, the radio communication apparatus identifies the type of the data, and checks whether another data terminal equipment is transmitting data by detecting a carrier. If no carrier is detected, the radio communication apparatus monitors occurrence of a carrier for a time period determined depending on the priority of data to be transmitted. After elapse of the above time period, it is determined whether another data terminal equipment is transmitting a carrier indicating intention to start data transmission. If it is concluded that no such a carrier is detected, the radio communication apparatus transmits a carrier a predetermined number of times, and then starts data transmission. This technique allows data having a high priority to be transmitted earlier than low-priority data.
