Abstract
An optimal channel is selected in correspondence with the radio environment of the setting place of a system. A plurality of channels are divided into a plurality of groups, and a communication is performed using a channel in a group selected according to the radio environment. Since channels in the group are selected to be free from intermodulation, even when a plurality of communications are simultaneously performed in the system, the communication using one channel can be prevented from influencing that using another channel.
Claims40
A radio communication apparatus comprising:
- storage means for storing at least one group including a plurality of radio channels where an influence of intermodulation has been considered when the radio communication apparatus simultaneously performs communication with a plurality of radio communication apparatuses;
- selection means for selecting a radio channel among the plurality of radio channels included in the group;
- and
- control means for controlling communication using the radio channel selected by said selection means.
A radio communication system having a plurality of radio communication apparatuses and a radio control apparatus, the system comprising storage means for storing at least one group including a plurality of radio channels where an influence of intermodulation has been considered when the radio communication apparatus simultaneously performs communication with a plurality of radio communication apparatuses,
- wherein said radio control apparatus comprises:
- allocating means for allocating a radio channel in the group to each of the plurality of radio communication apparatuses, and
- said radio communication apparatus comprises:
- communication means for performing radio communication using the radio channel allocated by said allocating means.
A control method for a radio communication apparatus, storing at least one group including a plurality of radio channels where an influence of intermodulation has been considered when the radio communication apparatus simultaneously performs communication with a plurality of radio communication apparatuses, comprising the steps of:
- selecting a radio channel among the plurality of radio channels included in the group;
- and
- controlling communication using the radio channel selected in said selecting step.
A control method for a radio communication system having a plurality of radio communication apparatus and a radio control apparatus, the system comprising storage means for storing at least one group including a plurality of radio channels where an influence of intermodulation has been considered when the radio communication apparatus simultaneously performs communication with a plurality of radio communication apparatuses,
- wherein the radio control apparatus comprises the step of:
- allocating a radio channel in the group to each of the plurality radio communication apparatuses, and
- the radio communication apparatus comprises the step of:
- performing radio communication using the radio channel allocated in said allocating step.
