Abstract
A discrimination unit of a communication apparatus discriminates information on devices configuring a network, and a selection unit of the communication apparatus selects whether or not to execute a process of selecting an antenna to be used in communication, based on the information discriminated by the discrimination unit. The information discriminated by the discrimination unit in the present circumstance is type, the function, the type of power supply, or the remaining battery life, of other communication apparatuses.
Claims15
A communication apparatus comprising:
- a Multiple Input Multiple Output (MIMO)-antenna-selection device which selects antennas to be used in MIMO technology communication;
- a discrimination device which discriminates a type of another communication apparatus;
- a decision device which decides whether or not to execute an antenna selection process for selecting antennas to be used in the MIMO technology communication by the MIMO-antenna-selection device, based on a discrimination result by the discrimination device and a type of the communication apparatus;
- and
- a communication device which communicates with the other communication apparatus using a MIMO technology in ad hoc communication in a case that the decision device decides to execute the antenna selection process, and without using a MIMO technology in ad hoc communication in a case that the decision device decides not to execute the antenna selection process.

A control method of a communication apparatus, comprising:
- selecting, by a Multiple Input Multiple Output (MIMO)-antenna-selection device, antennas to be used in MIMO technology communication;
- discriminating a type of another communication apparatus;
- deciding whether or not to execute an antenna selection process for selecting antennas to be used in the MIMO technology communication by the MIMO-antenna-selection device, based on a discrimination result in the discriminating step and a type of the communication apparatus;
- and
- communicating with the other communication apparatus using a MIMO technology in ad hoc communication in a case that it is decided to execute the antenna selection process in the deciding step, and without using a MIMO technology in ad hoc communication in a case that it is decided not to execute the antenna selection process in the deciding step.
