Patent number: 8121554Abstract: A data rate is to be determined depending on circumstances. A control unit (30) transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit (30) receives rate information from the targeted radio apparatus. The control unit (30) sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit (30) identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit (30) lowers the frequency at which the rate request signal is transmitted.Type: GrantFiled: June 26, 2006Date of Patent: February 21, 2012Assignee: Sanyo Electric Co., Ltd.Inventors: Yasuhiro Tanaka, Seigo Nakao, Ken Nakaoka, Akifumi Hirata, Kiyoshige Ito, Yoshiyuki Otani

Publication number: 20120040703Abstract: A processing unit generates timing information on timing, with which each of radio apparatuses is to synchronize in communication between the radio apparatuses when each of the radio apparatus broadcasts a signal, to control the communication between the radio apparatuses. A modem unit and the like broadcast the thus generated timing information. An RF unit and the like receive a signal which is synchronous with the timing information broadcast by them. When a signal which is asynchronous with the timing information and when the duration of this signal continues for a period longer than a first threshold value and the quality of this signal is more deteriorated than a second threshold value, a decision unit detects that the received signal is a disturbing signal. The modem unit and the like also broadcast to the effect that the disturbing signal has been detected.Type: ApplicationFiled: January 28, 2010Publication date: February 16, 2012Inventors: Kunihiro Kawase, Ken Nakaoka, Hanae Suzuki, Yoshiyuki Otani

Publication number: 20100290522Abstract: The control unit verifies whether or not the coded data of one frame has been transmitted within each frame period. When it hasn't, the control unit increases the compression ratio of a compression unit.

When the amount of coded data is greater than or equal o the first threshold value, the control unit increases the compression ratio of the compression unit. When it is less than or equal to the second thresh hold, the control unit lowers the compression ratio of the compression unit.Type: ApplicationFiled: November 13, 2008Publication date: November 18, 2010Applicant: SANYO ELECTRIC CO., LTD.Inventor: Yoshiyuki Otani
