<p><P>PROBLEM TO BE SOLVED: To provide a communication terminal device to which two or more radio communication modules carried in an identical cabinet can perform stable transmission. <P>SOLUTION: A game instrument 10 has a first radio communication module 12 and a second radio communication module 14. The first radio communication module 12 performs transmission using a Bluetooth protocol. The second radio communication module 14 performs transmission using an IEEE802.11 protocol. The first radio communication module 12 and the second radio communication module 14 have a common reference transmission period and communicate at a transmission period of integral multiple of reference transmission period. A controller 16 establishes an offset time from a start time of transmission of the first radio communication module 12 to a start time of transmission of the second radio communication module 14. At this time, the controller 16 supervises transmission loading of the first radio communication module 12, and establishes the offset time based on monitor result. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
