Abstract
A wireless communication device according to an aspect of this invention includes a main body antenna to communicate with the antenna of a wireless card, and an antenna position setting unit capable of setting a plurality of types of positional relationships between the antenna of the wireless card and the main body antenna.
Claims8
A wireless communication device comprising:
- a main body antenna to communicate with an antenna of a first wireless card;
- antenna position setting means capable of setting a plurality of types of positional relationships between the antenna of the first wireless card and the main body antenna;
- communication means for performing communication between the antenna of the first wireless card and the main body antenna which are set to a predetermined positional relationship based upon the normal position relationship between the antenna of the first wireless card and the main body extension by the antenna position setting means;
- and
- positional relationship control means for controlling setting of the positional relationship between the antenna of the first wireless card and the main body antenna by the antenna position setting means subsequent to a setting based upon the normal position relationship between the antenna of the first wireless card and the main body extension, and as needed on the basis of a communication state by the communication means;
- wherein the positional relationship control means stores the normal position relationship between the antenna of the first wireless card and the main body antenna as communication log information, and when communication is implemented normally in a first communication process, initially sets the antenna of a second wireless card and the main body antenna to the normal position relationship, on the basis of the communication log information, in a second communication process subsequent to the first communication process.

A wireless communication method comprising:
- performing communication between an antenna of a first wireless card and a main body antenna which are set to a predetermined positional relationship based upon the normal position relationship between the antenna of the first wireless card and the main body extension;
- changing the positional relationship between the antenna of the first wireless card and the main body antenna subsequent to a setting based upon the normal position relationship between the antenna of the first wireless card and the main body extension, and, as needed on the basis of a communication state between the antenna of the first wireless card and the main body antenna which are set to the predetermined positional relationship;
- and
- performing communication between the antenna of the first wireless card and the main body antenna which are set to the changed positional relationship;
- wherein the normal position relationship between the antenna of the first wireless card and the main body antenna, and when communication is implemented normally is stored as communication log information in a first communication process, the antenna of a second wireless card and the main body antenna is initially set to the normal position relationship on the basis of the communication log information, in a second communication process subsequent to the first communication process.
