Abstract: An RRH includes a power supply device, an AISG interface, a PA, and a control unit. The PA is operated by a power source with a first voltage or a second voltage that is lower than the first voltage and amplifies a transmission signal. The AISG interface is connected to an antenna control device operated by the power source with the second voltage. The power supply device supplies the power source to the PA and the power source to the antenna control device to the AISG interface. When the antenna control device is operated, the control unit controls such that the power supply device generates the power source with the second voltage, supplies the generated power source to the PA and the antenna control device, and increase power of the transmission signal output from the PA that is operated by the power source with the second voltage.

Abstract: A control device of a receiving device includes an interference wave detector that detects an interference wave within an intermediate frequency band in a signal converted by a mixer that converts a reception signal of a radio frequency band with a certain radio frequency as a center into an intermediate signal of the intermediate frequency band based on a signal of a local oscillation frequency different from the radio frequency. The control device further includes a frequency controller that changes the local oscillation frequency so that the intermediate frequency band gets away from a band of the interference wave when the interference wave is detected.

Abstract: A feedback section acquires an analog signal that has passed through a band-pass filter, and converts the analog signal to a digital signal. A digital signal processing section compares the digital signal obtained from the feedback section and an input digital signal with each other to measure modulation accuracy, and performs delay correction on a subsequently input digital signal so as to improve the modulation accuracy.

Abstract: In a master device, an address for a transmission origin and an address of an ultimate transmission destination, included in a message from an end device, are stored, as a pair, as proxy information, and the address of the transmission origin included in the message is overwritten with the local communication address, to form a proxy message to the destination device. Moreover, the master device performs a search for a round-trip route to the destination device and sends the proxy message to the destination device following the outbound route that has been searched. The destination device, upon receipt of a proxy message, sends back a message to the master device following the inbound route that has been searched by the master device. The master device uses the proxy information to send back, to the end device, the message from the destination device.

Abstract: Based on slave information from a master device (a maximum number of connectable slaves Nmax and an address reporting period) and on a device number #n that is set locally, slave devices calculate address information reporting timing and, after a delay, report the local address information (a logical address and a communication address) to the master device with each period. Each time address information is received, the master device stores a combination of the logical address and the communication address, and if, at the time of this storing, a logical address matching the received logical address has already been stored, checks the communication address that is stored in combination with that logical address, and if the received communication address does not match, determines that the received logical address is redundant.
