To provide an communication apparatus such as a facsimile apparatus that allows
radio communication in different modes to be used so that efficient communication
can be implemented. For instance, even in a state where the image reading section
(hand scanner) is removed, it allows an image read by the facsimile apparatus to
be sent to another first terminal and simultaneously radio-communicated to a public
switched line by a second terminal by way of the facsimile apparatus. Also, it
allows a quality cordless telephone function to be implemented by a TDMA radio
line and simultaneously high-speed transmission of image data and so on to be implemented
by a frequency hopping radio line. The communication apparatus according to the
present invention is characterized by concurrently using a radio communication
line such as TDMA of which transmission band is guaranteed to be used although
its transmission speed is not fast as exemplified by PHS and a radio communication
line such as frequency hopping that has a possibility of interference occurring
in the transmission band although its transmission speed is fast as exemplified
by Bluetooth.
