18. A wired/wireless bridge device for relaying communication data between a wireless host performing a master operation and at least one device performing a slave operation to communicate with the wireless host, comprising:
-
a wireless communication unit transmitting/receiving packet data to/from the wireless host via a radio link; and
a wired communication unit transmitting/receiving packet data to/from the device via a wired link, which limits transmission/reception of packet data to/from the device if a communication bandwidth of the radio link is below a threshold bandwidth that is set based on a transmission/reception amount of the packet data with the device. - View Dependent Claims (19, 20, 21)
