摘要 |
[Object] To enable reduction of electrical power consumption and efficient use of channels. [Solution] A sending apparatus is configured to be able to support a plurality of transmission modes that use different occupied frequency bands in a channel. When user setting information indicates that electrical power consumption is reduced, a coordinator decides upon a transmission mode on a narrowly occupied frequency band side so long as a condition that a transmission rate necessary for transmission of digital information is satisfied. In order to make it possible to use a channel adjacent to a certain channel in sending of digital information from another sending apparatus, the coordinator changes a transmission mode whose occupied frequency band is wide to a transmission mode whose occupied frequency band is narrow for the transmission using the certain channel so long as a condition that the transmission rate necessary for the transmission of the digital information is satisfied. |
