Abstract:
1. A method for communicating between apparatuses by selectively using a plurality of communication methods including a centralized control method, in which each communication apparatus sends and receives data according to an instruction issued based on a schedule providing sending timing of each of the communication apparatuses, from a control apparatus, and a distributed control method, in which each communication apparatus performs carrier sensing, and sends and receives data in an autonomous distributed manner, the method comprising: detecting radio frequency interference; searching for an available radio frequency channel when a predetermined radio frequency interference is detected; switching to the available radio frequency, when the available radio frequency is found when the predetermined radio frequency interference is detected when communicating with other communication apparatuses using the centralized control method; switching from the centralized control method to the distributed control method, when the available radio frequency channel is not found when the predetermined radio frequency interference is detected when communicating with other communication apparatuses using the centralized control method; temporarily storing received data; and increasing an amount of received data that can be temporarily stored when the centralized control method is switched to the distributed control method.
